In this video, Stefan of CNC Kitchen makes an amazing discovery. By annealing 3D prints in plaster, you can significantly improve their strength and their heat tolerance.
He did have some issues with “demolding” the parts from the plaster and plans to do additional tests. It will be interesting to see where this leads. As someone adds in the comments: “Before putting in plaster, coat with a sealer and then a mold release. Avoids moisture absorption and reduces cleanup.”
