Wildcard week


Design and produce something with a digital fabrication process (incorporating computer-aided design and manufacturing) not covered in another assignment, documenting the requirements that your assignment meets, and including everything necessary to reproduce it.

I'm really looking forward to Wildcatweek. Now I have to decide what I want to do. Since I can decide badly I will try two things.
I would like to build individual boxes for my electronic parts. I will first create the form and then deep-draw it.
The second thing I would like to try is to cast a gripper out of silicone which is controllable by air pressure.

Individuel Boxes

I would like to create boxes in which exactly my circuit boards, electronics components and the necessary tools to assemble pure fit.
These are to be installed later in my box for the robot system. For this purpose they should be in the form of mines again. This shape is not very suitable for a wooden box so I would like to thermoform them. Another advantage is that I can use transparent material so that you can see directly from the outside what is inside the box. First of all I have to make the moulds to be able to thermoform them. For this I would have different possibilities.
I create a 3D print and draw it deep - that would be impractical in many ways. First of all I could print the form directly. And if you want to thermoform a 3D print you have to make sure that you print it with as much infill as possible otherwise it will deform.


Filocut is a machine that can cut 2D polystyrene foam with a heatable cutting wire. It is possible to load vertig created dfx files or to create them in the software itself.

Vacuum Thermoforming machine


This is a vacuum thermoforming machine.

workspace 430mm x 280mm 160mm


Now that I have created the form out of stüropor he has to prepare it a little bit because the material will be heated during the deepening and so the styropor would melt.


Because my boards would fall out now I made another cover with the laiser cutter.


I would like to create a gripper for my robot system, which can be put into one of the dice. I started with the 3D disein that was easy.

Desine and Cast

So I used different silicone. But with that I had some problems because we had the wrong one in the lab so I could have formed face masks with it but it didn't get hard enough. But now I found the right one and started with my first tests.
