We have one Bukito 3d printer, from the Kickstarter by Deezmaker.
Glen assembled it at the Deezmaker store in Pasadena.
This device prints in PLA and nylon using 1.75-mm filament; here is a link to the inventors' specifications.
Would you like to borrow it, to have a few of your students see their own designs printing? Please let us know, and please try to find your own filament to use (until the day when we find the funding to provide you with filament ourselves).
