Hot Melt Injection Mold for Maker Faire Robot
Description
*Update (7/1/17):* Turns Out This Design Is Nearly Identical To An Earlier Design: Https://Www.Thingiverse.Com/Thing:796654 Which Another User Just Brought To My Attention. Check It Out, Too! This Is A Test Of A Mold For Hot Melt Glue Injection Molding. I'M Not Sure If It Is Good For Anything, But I Wanted To See If It Is Possible To Injection Mold Hot Melt Glue In A Pla Printed Mold. (It Is!) I Started Off With The Iconic Maker Faire Robot (The Manos Arriba Version) And Created A 2-Part Mold. I Added An Inlet Port And Outlet Ports At The Extremities.To Keep From Melting The Input Port With The Hot Melt Glue Gun Nozzle, I Also Designed A Small Sacrificial Input Duct That Does Get A Little Melted, But It Is Easily Replaced. I Was Worried That The Hot Melt Glue Would Simply Melt The Mold, But Even Though I Was Using High-Temp Hot Glue (The Gun Gets To About 220C) The Mold Survived Fine. The Only Use I Can Think Of For This Technique Would Be For Over-Molding/Potting Of Electronic Components Or Small Circuit Boards.
