I made my own clear plastic tooth aligners and they worked
Not to be a downer, but was any thought given to the safety of the plastic(s) used?This is something that's in your mouth a lot and constantly exposed to saliva.The Dimension 1200es mentioned doesn't appear to be specific to medical applications.[0] The product page lists the only compatible thermoplastic being ABSplus-P430. The MSDS for that basically says the stuff is dangerous in molten form, and beyond that there's very little data.[1] The same company makes "Dental and Bio-Compatible" materials for use with their other products, and these appear to have considerably more safety data.[2]>The aligner steps have been printed, in addition to a “riser” that I added in order to make sure the vacuum forming plastic (sourced from ebay) ...As another commenter pointed out, the vacuum forming plastic is probably the primary concern because the 3D printer was just used to create the molds. The specific type of vacuum plastic isn't mentioned.Regardless, very neat project.[0] http://www.stratasys.com/3d-printers/design-series/dimension...[1] http://www.stratasys.com/~/media/Main/Files/SDS/P430_ABS_M30...[2] http://www.stratasys.com/materials/material-safety-data-shee...
