Joris Peels from the 3D printing startup Shapeways has been experimenting with making stovetop bioplastics, with mixed (but promising) results:
Overall making bioplastic at home was a fun activity. It had a certain magical, "oh my, I made plastic" quality to it. Bioplastic in thin sheet form does seem to be a fun and practical application as a build material. However right now the results, as far as I have found with molds, are not promising enough for one to be able to use it to make your own things or to produce plastic for your DIY projects. I need to qualify this by saying that any of the problems with the bioplastic could of course be my fault for not cooking it long enough, cooking it too high/low, measuring out the proportions incorrectly, using the wrong starch,drying the bioplastic in too hot/too humid/too dry a room etc.
Taking that into account, at the moment shrinkage, warping and the long drying times, as I have found them, make it unpractical. As for using it as a 3D printing material, I am not comfortable enough with this material at the moment to even properly test it in a 3D printer. The "gunky" quality and long drying times seem to currently make it impractical for use as a 3D printing material. Someone could possibly tweak the recipe and make it more practical both for 3D printing and molding and I hope this happens. Perhaps you could with some careful experimentation be the one to make bioplastic a practical reality for molding and 3d printing?

In ye olden days, a telephone user had to ask the operator to call the desired party and make the connection. Then the dial telephone empowered us all to, er, reach out and touch someone. This 1927 instructional film from the telephone company explains the basics: “The ringing signal is an intermittent burring sound telling […]
