First experiences with a BCN3D Sigma

By | 3D Printing | No Comments

This week Tresdenou delivered tome a BCN3D Sigma R17 3D printer.

I was looking for a Dual Extruder and that it was quite plug’n’play for once 😉

And my choice was between this one and the one from Ultimaker. I went for BCN3D being cheaper and local.

Sigma R17

The first experiences this week are very positive, still few things could improve.

The packaging shows a good deal of thought behind, interface is simple and there are plenty of improvements compared to my BCN3D original 4 years old already.

As you start an assistant kicks in that lets you load filament and calibrate heated bed and the extruders. Very simple and effective.

And then you make it work as usual with a SD card.

The software seemed to me a bit basic because it is a customized version of Cura for BCN3D and it is not updated. So I am missing some functionality for example the support options are limited. There is also the option to use Simplify3D but I haven’t tried yet.

With the software you also get profiles for different materials and quality by default which makes things easier.

The same night I unboxed I was already printing, after doing the setup process 🙂

With BCN3D I have a problem that I need to sort out. It doesn’t print with exact size on Z axis. Since I had to change the electronics a couple of months ago, I don’t have a clue of the reason behind…and I think it was happening already before that. The fact is that for 3D printing services that require exact measurements I was not in a condition to provide them, wile for figurines and other objects without precision there was no issue at all as we speak of a difference of 1 mm over 150 mm total height.

And now with the Sigma I just got a couple of requests packed in this week about parts for 3D printer kits. Waiting for the feedback 😉

 

While I am writing this I am 3D printing a Draudi in two colors, a must!!

Cura con Draudi

Cura customized version for BCN3D

The progress up to now:

 

From this four days here is what I liked more and what I liked less:

More

  • Initial experience. The packaging is well thought, with documentation, tools and first steps properly guided.
  • The 3D printer management is simple with clear menus, and the usual functions maximum two clicks away. Filament change and calibration are walked through and easy to perform. The slicer piece could be simplified a bit more, but they already provide default profiles and their website has a profile generator that makes its use even easier. However, I think Cura shows too many options if it is for a newbie that only wants to always get good 3D prints and that’s all.
  • Dual independent extruder. It looks pretty good and has plenty of potential. After the Draudi in two colors, PVA supports is the next thing to try 😀
  • Quite silent, as fara as I heard it is an important improvement to the previous Sigma version.
  • Amazing jump compared to my first 3D printer, the BCN3D, from the same company called RepRapBCN at that time.

Less

  • The interface is simple but the trade-off is that it is also limited. For instance if you have a problem in filament load process you cannot stop it. It happened to me that I started the setup again since I did not complete it in the first round and I messed up (user fault :P). The filament load started when I already had filament loaded and I could not stop it, unless I switched off the machine. The outcome was that the motor kept pushing filament as in normal procedure and made a dent to the filament while it was blocked in the end. Then it could not push anymore. I had to find a way to push the filament a bit more so it got grip again. It also happened to me that when the filament is not caught at first try it pushes following the procedure but may get only to half the bowden tube. Then, following the next procedure step of fine tuning load you have to keep pushing the button many times at low speed until you get it loaded properly, caught in a process that was thought for the last mm probably.
  • I understand it has bowden because there is enough complexity in X axis with the IDEX system, but it does not seem to me that it get the speed advantage that a lighter carry would bring. Like in Delta printers for example. For now I 3d printed properly at 100 mm/s.
  • LEDs are nice, but I am afraid there is no way to switch them off. If oyu leave the printer working at night, you know the drill…

Several disclaimers

Although I know BCN3D Technologies and its CEO Roger, I have no relationship with them. I bought this printer because I think this is a good machine among Dual Extruders.

In fact I bought it at Tresdenou, a shop in Poble Nou (Barcelona) managed by Rafa and César. They are members of the 3D Print Barcelona group for three years I guess, but less involved lately since they have to cover the commercial schedule and we meet just at the other side of Barcelona.

Good people, always willing to help, and I did not doubt for a second buying from them since I know I would have excellent local support if I need it. ¡¡Very recommended!!

I bet for local. You know, if you buy from China you better be independent to repair all the issues that the machine may bring at the beginning, or those that you can make afterwards.

This post is not in any case a review of the machine, simply my first impression as advanced user. I do not perform thorough reviews and I do not have intention to perform them. For this you have several youtubers that have already published.

Enjoying our 3D printing project: the VIT

By | 3D Printing, Startup | No Comments

We are just few days from the Makerfaire Rome, after the craziness of Barcelona Printer Party this Saturday where I am also part of the organization. And in just a couple of days we leave for Rome.
makerfaire rome

Days of intense activity. We continue at top speed with the last external finish details of the third VIT prototype, a low cost laser sintering 3D printer. There are few options in the low cost range for 3D printers of SLS technology, and we expect high demand at least from the request received up to now from interested resellers.

VIT 3D printer front

The VIT 3D printer prototype version 2
In addition, we are preparing a crowdfunding campaign for Kickstarter, to be launched when I return form Nepal. The initial aim was to launch by mid October, but the campaign preparation requires more work than we thought.
When you watch others campaigns you get the feeling that it’s two guys that met, made a video and took some pictures and that’s all…but everything needs to be thought and calculated. The major difficulty is to define what you get in exchange of the rewards. Because if you make a mistake it goes against you, and it does not happen often to ask for additional money and it is not well considered anyway.

One aspect that is becoming more complex than expected is shipment, for example, since the volume of a machine plus the 10kg powder is a European pallet of 130cm height and almost 140kg.
Well, I said this before shooting the video!! this will really be difficult 😛
These are intense moments, but also very exciting. What we do now determines the future of the Natural Robotics company and its growth. Let’s see how we remember this in a while!!
I got friends that started an entrepreneurial activity related to 3D printing and had to shut down. I hope I learnt something from the mistakes they shared with me…

Mochila reparada

Backpack repair with 3D printing and the Delta Black

By | 3D Printing, DIY | No Comments

3D printing is so polyvalent, that one gets lost with the amount of things you can do, be printing existing objects from repositories such as Thingiverse or Youmagine or create new designs.

My view is that at he beginning people get caught with printing things from those repositories, but quickly discover he part that brings more passion in 3D printing: to imagine something, to model it and to print it. What I like most is to build small solutions. Quick and pragmatic. And I applied this to several things at home or with mountain equipment. Knowing that the strength of pieces is almost zero compared to what is required in mountain activity, just be careful. No belay material. And don’t dare to print a carabiner!

The problem

The other day I broke a backpack, one of those you get in courses, a piece of cloth with metallic parts that did not last long. But looking at the design, it does not surprise me.

Mochila rota

The metallic supports for the small ropes had a very small contact surface, so the cloth just broke apart from the metallic piece. Then I took the caliper, and started measuring the current piece in order to have a starting point to improve it.

The solution

I just had to do a top for the small ropes that as enough wide to avoid breaking the cloth again.

I keep using MOI for modeling, especially when you look at something more organic. In fact it’s a spin-off form Rhino…

MOI tope mochila

I uploaded the model to Thingiverse here.

Mochila reparada

This is what I really like from 3D printing, the capacity to solve things. You will see plenty of jars and figurines 3D printed in the fairs. But what really adds value is the ability to design, model and create useful objects, and not talking about prototypes. In my case what gives me more satisfaction i exactly this, to repair or to improve something in a matter of minutes of design work. And some more to 3D print it.

3D printing at ultrafast speed 500 mm/s

In addition, since I co-founded Natural Robotics I have plenty of Delta Black 3D printers at my disposal. If there is something to mention that makes them special its their speed.

In less than four minutes I had the object printed. I took the opportunity to record a video, the first ever that I am talking :O

And the thing is that it went very improvised, and so you notice because yes, it’s totally improvised 😛

 

This is the perfect use case to print at maximum speed, the amazing 500 mm/s. The piece was a top that goes inside the backpack, and is not visible so if the print finish is not completely perfect nothing happens. My goal is to print it in the lower possible amount of time.

This is also applicable to prototypes where you only want to check the shape, more than details. We have performed quality printings at 350 mm/s, which is a speed highly outstanding already if we take into consideration that a cartesian 3D printer usually prints at 100 mm/s.

New spool holder

Updating my 3D printer – spool holder

By | 3D Printing, DIY | No Comments

I have a BCN3D 3D printer that starts to be a relic now. I built it three years ago in a workshop from bcn3dtechnologies, reprapbcn at that time.

And during these years I did several upgrades at different moments: layer fan, full metal extruder, and an auto bed leveling that I have not finished yet because I need to tweak the firmware. Hardware is in place and I am waiting that we organize the next 3D Printer maintenance workshop in 3dprint Barcelona group to finish the job.

The Marlin firmware provided by RepRapBCN had several functions skimmed, so I need to pick up a recent Marlin version and transfer all the configs from my printer, plus check if there is any function out of standard that I need to transfer.

It’s in my ToDo list…

In the meantime, some weeks ago I upgraded the spool holder. The original one broke in several points, due to a design shortcoming. This is clearly due to

moving the 3d printer around, to different events such as maker faires, printer parties and so on. By the way, we are organizing a Printer Party in Barcelona for October 8th.
I took the original spool holder STL files from BCN3D+ 3D printer and reused some of the material I had in my broken spool holder.

Old spool holder

Final result is here. I would have liked something more flexible to change the holder position according to the spool size, but I do not have time to work on it right now. In fact with independent screws for both sides it’s probably easy to adjust.

New spool holder

Anyway this is more for nostalgic feeling, I got now plenty of Natural Robotics 3D printers at my disposal 😀

Check the Delta Black, a fast FDM 3D printer…

3D printing – the hype is finished

By | 3D Printing, Thoughts | No Comments

We are all human and we cannot avoid to get excited. This explains some of the bubbles, magnified by the natural drive to greed for some people.

3D Printing for consumers

We also suffered this with 3D printing. In fact, it follows the natural cycle that Gartner points in the Annual Hype Cycle Chart.

lt’s interesting to see in this blog the evolution of Gartner charts since 2012. Consumer 3D printing moved from the peak of Inflated Expectations to way in the Trough of Disillusionment. However, Enterprise 3D printing is approaching the Plateau of Productivity.

 

gartner-hype-2012-to-2015

The effect is already visible, with several movements and announcements:

Pinshape joins Formlabs

3D Printing for Enterprise

In Enterprise 3D Printing there is not much to say. The industry existed for thirty years, formerly known as Rapid Prototyping and it will continue to grow. I don’t know the 2015 stats, but until now and for all these years this industry experienced annual growth rates of 25-30%.

Whv? Because 3D printing has obvious advantages for prototyping. In addition, during this hype period new fabrication techniques and tools, or substantial improvements, have moved 3D printing from the prototyping scenario to final product fabrication. This is the case of aeronautical companies, automobile, health and others that benefit of 3D printing fabrication of high value added products.

lt is true that 3D printing allows making objects with complex geometries, impossible to build in another way. So they simplify the fabrication process, add lightness and strength with maximum customization, and these advantages keep spreading into more and more industries. Enterprise 3D printing will not stop growing since there is a clear driver for improvement.

Conclusions

On the other hand, the consumer 3D printing is decreasing. Deception among consumers?
Probably. The manufacturers also deserve it somehow. I remember pictures of Makerbot a couple of years ago where they were showing objects that were not made with their own printers, pure unfaithful marketing. The consumer has not been properly educated, giving the impression that it was another home appliance and as easy to use as an appliance, only thinking about selling and selling more. While in fact the printers have maintenance, have problems, bottom line you need to be patient. And all this to make objects that are not wonderful in fact.

You reap what you sow, so here it is: Disillusionment.

In our 3D Print Barcelona group we have been using 3D printers for years, and we make clear the constraints and limitations in our Introduction events. Sooner or later you will have to deal with the 3D printer. Our group events continue to be fully crowded, so I cannot tell from this if there is a downward trend.
In fact events like “3D printing workshop: from your mind to your hands” had a waiting list longer than the attendees numbers. We scheduled another session and we had waiting list again. What is special here? it is hands-on. We explain how to make the whole process starting with the idea, modeling with an application, slicing to transfer it to the 3D printer and finally the printing.

There is no star use case for consumers. For example, 2D printer avoided people to go to the printing shops then. I think it was more about comfort than price, since the price per liter of the ink is way higher than any other liquid on the planet. Now 2D printers are also in a downward trend because the smartphones adoption has made us all more digital. One example: you don’t need to print the ticket anymore to attend an event, or the boarding pass to board a plane.
In 3D printing you have two options as a consumer:

  • You model objects yourself
  • You download models from a repository

Using only the second option does not justify the cost of a 3D printer. However, there was a study that concluded that printing your day to day objects was even cheaper than buying them so you could offset the printer cost.
When I started in 3D printing 3 years ago I thought modeling was the bottleneck, the one thing that prevented 3D printer massive adoption at home. I was thinking about the long learning curve of a CAD application then. But when I see software so intuitive as TinkerCAD, I think this is not the problem anymore.

The problem is to have something to print. And I am not talking about the usual Yodas and vases. I am talking about something that people need, in the broader sense of need.

Leaving hobbies particular cases apart and the prosumers who use the printer for some professional or almost professional activities, what people around me is printing at home is:

  • Replacements and repairs. Old spare parts that broke and there is no replacement. You model it and you print it. e.g. an old microwave button.
  • Objects improvements. Tuning stuff. e.g. a bicycle support, GoPro accessories.
  • Practical customized objects. e.g. small drawers to keep something in particular, USB cables support to fit at your table, etc.
  • Decoration. The vases and the Yodas!

Yoda ABS

You have to be passionate about the topic to get involved, honestly.
How many 3D printers may be parked somewhere at people’s home? Who knows…
Anyway I am ta king at macro levels. The big sales and consumer industry growth are gone, does not mean that there are niches that will continue to grow.

In prosumers it’s obvious, the DLP 3D printers bloomed and there are more and more jewelry shops that use them. Designers need to see their creations quick and with the ability to perform iterations, no sense to order it outside since you offset the printer cost pretty soon.
Makers are always making stuff, it is a nice tool to combine with other things.
And we have the hobbyists. They find multiple options to apply 3D printing in their hobby. If it is related to small dimensions they may need a DLP 3D printer, for example for train models.

Let’s see how this evolves in the following months.

Mini MakerFaire Barcelona 2016

By | 3D Printing, Events, maker | No Comments

[Reviewing my blog I found a post that was never published. From February this year. Here it goes as is]

Last Sunday we went to the Barcelona Mini MakerFaire, that took place at CosmoCaixa. With our 3d Print Barcelona group.

It’s not the same to organize than to exhibit, clear enough. We just sorted out what we were going to do in a couple of meetings.

For the Printer Party it took us a month and a half with weekly meetings, it is really not the same 😉

We went around 10 volunteers from our group. I was even a bit embarrassed when sending such a big list of participants to the organization, but well, they know us..

Some stayed the whole day, while the rest were shifting between morning and afternoon.

The group article is in this link, so I am going to explain the most personal piece.

A petar

Few members of the group in  full action

The place got really crowded, we honestly did not know how it was going to go in such a far place, but it was already full the moment they opened.  And it got even more full during the day!

On Saturday I printed the group logo, in big size, so I had to make it in two pieces. First the “3D” that I could finish at home, then I had the “Print Barcelona” to do the they after during the faire because I had to bring the 3d printer to CosmoCaixa the afternoon before. All unloading was done this day.

Logo 3D

The logo, the piece made at home

So I started another print during the faire.

Logo 3D 2a parte

A failed printing attempt

We had fail samples already, but well, here goes a fail in time. If you look at the right side you will notice a warping. Lack of hairspray was the verdict 😉

Due to my involvement in LynxCross gym, a functional training a bit special because it includes vertical moves on a wall, I no longer follow the maker and 3d printing movement as I did in the past. There is a lot of DIY in my gym, if anyone is interested or curious to see it he is welcome! it’s in Sants neighborhood.

So that these type of events come in handy to get up to speed quickly. You can see things lije a 6 extruders 3D printer, or someone growing up mushrooms with a system automated with Arduino, and others in similar fashion that just keep me in surprise mode.

The most common were drones and 3D printers. We start to have some SLAs in Barcelona: one from Printhatshit, a new one from Raúl from Hangar and I saw another one shown by I did not have the time to talk to them.

Many known people from Barcelona circle between makerspaces and local shops, many of them from group members with a drive for entrepreneurship that have started their own business. And that unfortunately we see less by now, because they have to attend their own business!!

Plenty of good vibes between the people, David from 3D-Seed gave me a sample of PETG filament to test it, but I did not notice it was 1.75 filament and I continue with the old fashioned 3mm. Soon it will be three years with my 3d printer! so I had to give this sample to someone else in our group.

Roger from BCN 3D Technologies gave me a spool of PLA from Colorfila also to test it. It is local filament, and I am hearing positive comments about it, good that we have local products to supports entrepreneurs from here.

Jordi from Makers and Bits gave me a 3D printed minion also haha.

I am printing the second part of the logo again, to have it done once and for all. when it’s done I will test this filament.

From our stand the most successful were the the Fails. We could not get much because I thought about it the evening before. We knew there were many shops, showing the marvels that can be done with 3d printing. What could we add as a non for profit group? well, showing the less nice part, the fails. We all go through it and it is good that people know that it happens and how to prevent them.

Fails

In fact right there the filament broke and I had a fail. You can avoid it, by keeping the filament in a zip bag with dryer material away from humidity, but I haven’t done it before.

The second thing with most success were the 3D printed letters, because we were giving them for free! we had so many spared from the Printer Party that we still have to giver. In fact we missed something important, to add a sign stating that they were for free, only someone thought about it in the afternoon.

And then another thing that was catching a lot of attention from kids was the 3D printed Tetris, because you can play to place the pieces at your will. Some kids were directly jumping into moving pieces around without even asking…times change. What is interesting is the lack of references in some cases, it’s not a modern game, and I was seeing some kids setting pieces on the top side, like a jigsaw. Anyone that has played with Tetris puts the pieces starting at the bottom without even thinking about it, just where the pieces would fall in the game 😛

Tetris

I also met César and Sara from Makespace Madrid, that let me touch and hold the awaited “Manual de Supervivencia Maker” book. They made it happen, not without plenty of effort and issues that happen in such a project. In my case I contributed to the e-book version that I am already reading since few days.

 

Well, a full big day, with plenty of curious people, many creators and new things to learn.

Print the Legend

Print the Legend, the movie

By | 3D Printing, maker, Startup | No Comments

This weekend I finally watched the movie “Print the Legend“, it has been available in fact through Netflix since 2014.

Print the Legend

I was disappointed, because I thought there will be coverage of the open source movement in 3D printing, its origins with Adrian Bowyer and the RepRap project.

Nothing like this.

Focus is on the consumer and prosumer market: the creation and evolution of Makerbot and Formlabs. The star Bre Pettis and his fast evolution from maker to a corporate CEO, abandoning many of his initial values.

Climax moment when they decide to close the design and abandon Open Source Hardware. Zach Hoeken leaves the company with a clear declaration of disagreement with the new direction, he states it clearly in this post. I remember the comments for that period, but it is better to see the person explaining it in video.

I was shocked by the amount of people that were dismissed by the company, due to “not matching” the management point of view. With this accelerated growth all types of friction appear and you can see how they have to professionalize, up to the point of the big hit with the sale to Stratasys.

It is funny to know all the time across the documentary that Bre is going to stop being the CEO of the company…while he appears putting his life on it, loosing friends, loosing even his own identity for the company. As they say in The Godfather: “It’s not personal, it’s strictly business” 😛

Regarding FormLabs the most interesting piece is the Kickstarter campaign tha they ran -they closed 2.9 million dolars- and what it meant for them in terms of commitment, big delays to deliver, etc.

There is also an episode of founder leaving the company due to conflicts related to the direction to follow.

It seems this is the normal pattern in these startups with fast growth. Frictions show up, frictions that in a small group would be sorted out differently.

What is really sad is that a documentary just limits itself to this part of the planet like there was nothing else happening at the same time. Ultimaker is an example of startup very linked to the RepRap project beginnings and still operates from the Netherlands with an Open Source philosophy.

To summarize, it is worth watching “Print the Legend”, but have in mind this is a partial vision, only in USA, of the history.

Arácnido

Printer Party 2015 my small contribution

By | 3D Printing, Events | No Comments

After the biggest event this year for the group 3D Print Barcelona, the Barcelona Printer Party 2015, we decided to 3dprint all the robots and figurines the kids had made with during the TinkerPlay workshops.

I had to make a normal one and a winner one, this one printed in double size.

The normal gave me some hard times when trying to mount it, with some pieces even broken. I had to use glue to sort it out. Not because I had a lot of work with the printing, the whole thing took only two printing rounds. But the other one was a monster!

Despiece del normal

All the pieces of the normal size robot

For the winner figurine I did not take into account that you can modify the size of the objects in TinkerPlay, and that’s what the kid Eloy did. So I doubled the size of an object that was already big enough.

It took me several 12h printing rounds to get to this:

Arácnido

A sort of aracnid with a gigantic size

But I loved to see the pictures once mounted, especially those compared to a Lego figurine so you can really grab the size.

And it was really nice to see the kids amazed and starting to play when we delivered them.

Printer Party 2015

Barcelona Printer Party

By | 3D Printing, Events | No Comments

Our group 3dprintbarcelona.org is organizing a 3D Printing on Saturday, October 24th. The Barcelona Printer Party.

¡¡It will be huge!!

Altthough I show up as the founder of the group, since I got involved as co-founder of the LynxCross gym this year I do not spend much of my spare time to 3D Printing, and so Iam less up to date on what’s going on, and of course less active.

Fortunately the group counts with highly motivate people and we are making it through. It is a big organizational challenge for a group fully free and based on voluntary collaboration and lots of goodwill. In addition some members are over the acceptable geeky level…and I mean acceptable for already geek people 😛

We are making something huge. You can find the full program in our site (in Spanish).

In our group we usually do events every other week, with simple logistics. The Ateneu has already all the media and equipment we need, if it’s a talk the presenter brings his altptop in, we connect to the beamer and done.

But this is the event of the year. We made a similar one more than two years ago, at that time we called it “Primera quedada con impresoras 3d“, (I translated as “3D Printer Party” in my two languages blog) because we are not much creative haha. And for this year we have not improved in creativity and we adopted the term that people are used for this type of event. In fact we did not even spend time discussing the name, people in the group started calling it Printer Party and it stayed like this.

We’ve been about a month and a half working in preparation, with in person meetings every week to speed up organization. Online collaboration is really nice, but we speed up in person, provided there is a moderator to keep focus, usually my role 🙁

Printer Party 2015

If you do not know about 3D Printing

you will like it. You will see shops and business stands form Barceloan and whereabouts, you will have Introduction talks where you can ask all the things you want to know, that we missed to explain already: which 3dprinter I buy, how much it costs, which materials can be used, …and some workshops where oyu can learn the process completely, from modelling to get the real printed object in your hands.

If you have kids

it’s time to make them familiar with the new technologies. I recommend that you bring them in, we will do jumping frog races, we will show them to make a keychain with their own initial, ther ewill be workshops about TinkerPlay and TinkerCAD, two very intuitive tools for 3D objects design.

If you are really interested into making your kids familiar with technology, I recommend to attend the event from our friends Vailets Hacklab on Saturday 17th: the Vailets Hacklab Day. We are specialized in 3D Printing, and Vailets covers all type of digital technology such as robots, programming, arduino, etc…

If you are part of 3D Printing

You whould not miss the tinkerer/maker zone with the best inventions from hobbyists. See by yourself how we can tune and customize a 3D printer. And if you have something to show join us here

Maybe you are interested in the Rhino masterclass, or see how fast we can model simple objects with TinkerCAD.

Proud to be part of the 3dprinting movement

By | 3D Printing, Startup | No Comments

I am proud to be part of the 3dprinting movement in Barcelona.

It’s already two years since I involved myself in the 3dprinting scene by building a RepRap 3dprinter. I was conscious I didn’t know anything about it, so I built the BCN3D 3dprinter in a workshop conducted by RepRapBCN.
If you want to get into this, and don’t plan to buy a commercial product that you cannot touch or modify, best advice is the workshop.

my 3d printer

my 3dprinter

We created the Barcelona community, thanks to many people engaged and caring, many of us marveled by the possibilities of being a 3dprinter owner. The group 3dPrint Barcelona is active two years later. We are currently collaborating to build a drone for many of us and of course, frame will be 3dprinted.
Apart from this project experience we are also running talk events every other week where we give introduction to 3dprinting for newbies, we teach about software tools like CAD tools or slicers, or even hardware like arduino or nozzles. There is always a piece of networking having a drink afterwards, which is the most valuable piece for all of us to share projects and ideas.

logo-3dprintbcn

In fact there were people joining for fun, but others planned to have fun while they start a business related to 3dprinting.

And so we have seen several people from the group taking the risk and starting their own business:

TresdeNou with Rafael Bravo and Cesar Acero, a 3dprinting shop where you can buy 3dprinters, supplies and get scanning and printing services. Make your own figurine for example.

MakersandBits with Jordi Martin. Jordi provides 3dmodeling, scanning and 3dprinting services.

Printhatshit with Fran, a 3dprinting shop for makers where you can buy 3dprinter kits and supplies.

Redresins with Mirjam Versteegh and Beth Deavila, shop specialized in filament and resin for 3dprinters. They also resell the B9Creator 3dprinter in Europe.

Even if it is not a business, I also want to mention the work that Luis Rodriguez is doing in the food 3dprinting space. His blog 3digitalcooks is full of info about the scene with interviews to major actors and inventors, and you can have lot of fun reading through his experiments with his own food 3dprinter or other tools.

 

And what about me? I tried to build a business with 3dprinters a year ago jointly with some other group members, but we failed. Check my posts history for details.
I still love 3dprinting, but I also see that the consumer space, that had opportunities for small startups because the major players were not focused on it, is now starting to get crowded. Soon you will need a big investment to run anything on the hardware space. You can still open a shop and be a reseller but I see no fun on it. Prefer to build or create things!!

In fact, I am building a place in Barcelona which is a mix of a gym and an indoor rock climbing place. We will have boulder walls and also all type of equipment for functional training.
Classes will be guided, the activity is called LynxCross based on the lynx since we do not look for big muscle building but agility, flexibility and resilience. Check out here lynxcross.com
