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.

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…

I uploaded the model to Thingiverse here.

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.
