3D Printing Pen and Bioplastics

Using a 3D printing pen is much akin to using a glue gun. Except it's more finicky and unpredictable. I'm going to have to practice on this a bit. The bioplastics were a fail. I am not happy that they curled and became shrunken and disfigured. I supposed I can anticipate that they will warp in this manner next time I cook them up in my kitchen. Their texture is also odd. I wanted to create some kind of facial prosethics for special effects makeup, but I don't know if I want this touching my face.... Maybe there is a way to create biodegradable glitter if I mess with the formula and make it super brittle. I love glitter, but I hate how harmful to the environment it is.... Further experimentation needed. I have a kit of mica powder.... It needs to be used.
