OK so I have 3D printed and am currently smoothing and finishing a replica head of the robot IG-88 from Star Wars: The Empire Strikes Back.Here is a photograph of the object:https://ift.tt/2QFadB4 the objective is to be able to create a mold where I would be able to pour in X amount of resin to create the object with a hollow interior with about 1/8" thick walls as it currently exists in plastic.I very much would like to maintain its wall thickness and the void inside for wiring and lights etc.My initial thoughts on the process would bePlug the holes Rebound 25 brush on the entire outsideMake a 2 part mother moldFlip it upside down pour some silicone on the inside to create a flat surface at the bottomplace a plug inside the mold to fill as much as the void as possibleFill around the plug with Moldstar 15.So in theory now when i remove the plug I'd be able to collapse and remove the mold from the interiorObject would be casted upside down using the bottom collar as the opening1 - Does this method make any sense or is it comically bad?2 - If the above make sense, what are some steps i can take to make sure the interior silicone mold won't contact the walls if casted upside down?Does it make more sense to cast it right side up using the top as a pour spout? via /r/DIY https://ift.tt/2zUsVNX
