Lost PLA Casting: First Try at Casting 3D Printed Parts in Aluminum at Home.

Today I try to combine my metal foundry activities with my 3D printing activities. You can probably tell from "first try" that things don't go super well. I 3D printed a mug in Prusa PLA using my Original Prusa i3 MK2S. That part of the process went fine. I then combined it with some wax and foam for the sprue, that part went fine. I then put the 3d print into a plaster of paris mold. That was a bit less "fine" but it seems to work. in this video, i do the burn out of the plaster mold, melt the scrap aluminum into ingots, and also pour into the burned out lost PLA mold. It was... quite an adventure for me. The best adventures involve metal melting, and lots of fire from a janky propane burner. Here is the mug that i printed: https://www.myminifactory.com/object/... This furnace is loosely based on the "mini metal foundry" design by Grant Thomson but with a different refractory lining, the burner is based on the "Oliver Upwind" burner design by Lionel Oliver.
