This time i wanted to do a single solid cast part rather than a rotocast part.
this would require a different type of mold and casting in a pressurized environment.
I also wanted to experiment with a new technique for mold registration that i thought would make my process much more efficient.
Since i and many others have covered 3d print finishing techniques, silicone mold making and resin casting in the past i will skip over some of those details to focus on the more innovative portion of this project.
For the design I stuck with a melting theme but this time worked in the idea of melting weapons as i thought it suggested a sentiment of anti violence.
Step 1: Realize the concept
My software of choice is solidworks.
the knuckle design was a few simple extrusion commands, the first from the front plane to build out the actual knuckle portion and the second from the ground plane to create the general shape of the melted puddle. I added a few chamfers around the edges of the knuckles and a lof of filleting to blend the puddle in to the knuckle portion in a convincingly melted manner.
after the 3d work was completed the file was exported to an objet 3d printer.
after a significant amount of high grit sanding and a light gloss coat i had a pattern ready for a silicone mold.
