This video is awesome. You can make your own bioplastic. Starch, glycerine, vinegar and water. 7 parts water, 1 vinegar, .5 glycerine and 1.5 parts starch. You heat the mixture up while stirring. You can then flatten it and it will turn into a sheet of bioplastic. You can even add your own colors to it. The sheet can then be laser cut. You can make plastic and then laser cut it. Wow? I've been watching this video for 20 minutes now over and over again. Guess what I'll be doing this weekend? More than a little fascinated. Thank you Lasern!
At present we can only make flat forms, although it is possible to give surface textures. Our goal is to be able to make moulds, 3 dimensional structures, make waterproof material, and essentially have a database of material that can be used to construct anything using materials you can buy over the counter and use with tools you have in your kitchen.
I tried over the weekend. Was not successful. I tried a whole bunch of different recipes and proportions but ended up with varying degrees of material with a consistency not unlike that of hair gel. I will try again tonight . Would love to see the tutorial!
NIce result Matt!
It does shrink a lot, depending on your mix and the drying speed & shape. We played around with the vinegar and glycerine to see how it reacted as a plasticizer. Taking out the water out of it in the microwave took the water out really quickly, but make it also very brittle. There is a balance to find somewhere..
