For this assigment I decided to make a cyclops visor mount (from X-men 2).

I designed it on Inventor:

Then I 3D printed it.

After that I put some body filler and after sanding in order to get a better finish

3D printed model with body filler

In order to fabricate the mold I had to make a box (design and then cut with the lasser machine).

I mixed RTV silicone with 2% of its catalyst and then filled the box with the model inside as shown in the next picture

After some hours, we have to remove the 3D printed model

For the compiste I mixed Polyester Resin, "Cobalt" (Activator-1.5%), "Peroxid" (Catalyst-0.5%), Monostyrene (solvent-the necesary to get the correct viscosity) and add some glass fibber.

First I put the glass fibber into the mold and then the Mix :

Finaly the result :
