>>10361665>and then feed them in the opposite side to melt during the next injection so they are used up instead of getting stuck again.About how long are you findingyourself havingto wait between each shot then? Even if I only fill the chamber like 20% full of pellets since that's about as much gets melted each time no matter how full it gets, I still have to wait over a minute or two for that amount of pellets to melt. It's just frustrating and makes the entire process so slow. Completely defeating the purposeof rapid part production which is one of the whole points of injection molders. And that's with like20% of the chamber full which already makes it pretty useless.
>but I have yet to test it in 3D printed moldI'm not using ABS but with the softer materials I have tried, I've been testing with hand poured high temp silicone (Mold Max 60) mold halves within the aluminum mold frame (The large one from Buster Beagle 3D). I've done a good amount of research and seen people have success with Siraya Tech High Temp Resin mold halves both within aluminum mold frames, and also just loose but held together backed by wood and then clamped. If you don't use 3D printed mold halves in an aluminum frame, you'll want to put a metal washer at the opening, ideally sitting in a recessed round spot, so the hot nozzle doesn't make direct contact with the printed molds. Siraya Tech's High Temp clear and white resins are rated for up to 160C but the grey color is rated for up to 220C and I've definitelyseen videos where peoplehave had success with ABS using that. (pictured is a mold frame with some grey Siraya Tech High Temp resin molds) The only printer I have is a Formlabs one which is just too damn expensive to run large things (like mold halves) on, so I haven't tried 3D printed molds yet though.
