Molding and casting

group assignment:

review the safety data sheets for each of your molding and casting materials,
then make and compare test casts with each of them
compare printing vs machining molds

individual assignment:

design a mold around the process you'll be using,
produce it with a smooth surface finish,
and use it to cast parts
extra credit: use more then two mold parts

In the beginning I wanted to make a 20 sided dice. (a D20). I followed this tutorial I found online and used an old english font i found on dafont

My result:
It turned out cool looking but the topology didnt turn out great for the numbers and the design felt too complicated to mold so instead of risking ruining it I decided to switch it. Looks cool tho!

I Dice

So instead of using the dice I decided to try to use the puffin scan from the scanning week.

For this week I followed this great tutorial I found online

The fun began when I put in my STL file, it was far too complicated for Fusion and the software froze a couple of times when I tried to convert the stl into a mesh. I followed this tutorial for that part
Freeze

Eventually it worked. I simplified it a bit through the modify menu and followed Kevin´s tutorial on the mold. The biggest major difference is that he used the cut command when combining the object with the box. I did the opposite and simply combined them.

Next I created another sketch and extruded it. I then used the draft feature and put it on a 10 degree angle. I combined the objects and then exported it as an stl to print. I used the prusa 3d printer for this.
I began by making a miniature version of the mold.
This was mostly to test the silicone. We were unsure of whether it was still usable.

Here is the first test! I printed it through the Prusa 3d printer.
