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!
wow i really want to try this, though i have no laser cutter, i'll have to cut by hand. what kind of starch? what kind of vinegar? Can i use corn starch and white vinegar from the supermarket?
@jeff bare don't know if you could run it through the printer but you could try. @erica normal vinegar and corn starch are fine, we used a variation on this recipe - starch is starch.
We'll publish more info on processes next week, have been experimenting with accelerating process with microwave, which is an exciting development - at least for us.
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!
Documentation is a work in progress as we have to replicate. We aim to do some recording this week and find our how exactly we did it in the meantime a brief summary of the project can be found here.
Cheers for that! One of the two amazing things before breakfast.....the other one was Tm.10s Bruce Stirlings talk on Futurity Now. Synopsis "Pretend like its the future, and it will be!"
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..
Cooking & molding bioplastics at home: recipes, results & tips
Inspired by Mendel Heit, Martin Bauer and Jay Cousins we've been doing a lot of playing around with bioplastics. Here you can see the original post with a video that shows you how they made bioplastic. Additionally this video is quite helpful. So why ha
also, can you cut it to letter size and send it thru your ink-jet printer? that would be cool.

Will be recording how to today.

I'm going to experiment some more with it. Thanks for the idea!
Looks great. Mine all look milky white, how did you get it so transparent?
My molds are hardening by the way but I have shrinkage in a lot of the parts. Some parts are 30-50% smaller than initially.
