Since we're talking about casting, I figure I'd ask: Assuming that I learned how to properly make two-part silicone molds, is there a decent/reliable way to melt sprue in order to recast a piece? My dad is an engineer so I might have access to some tools like a vacuum pot to help reduce the chances of bubbles forming in the mold and casting process.
The reason I want to use the same plastic is because there are going to be pegs and holes on the parts that I need to insert into, and I'm pretty sure resin won't work for that. So ideally I want to melt runner into a very thin consistency, pour it into the mold, shake out bubbles and such, and use a vacuum pot to suck out any remaining bubbles.
