TPU (thermoplastic polyurethane) is any engineering thermoplastic in the class of polyurethanes. TPU properties include elasticity, semi-transparency (when desired) and resistance to oil, grease, abrasion and tearing. OnAdditive’s TPU for 3D printing is formulated for additive manufacturing applications. Please talk to OnAdditive before printing with this material. Black and Clear (natural) are stocked in .75kg (while supplies last), 1kg and 2kg spools. Red, blue, white, orange, yellow, green and gray colors are available on special order. Please note that limited experience printing colors (other than black and clear) TPU indicate that printing behavior may be different and need additional material profile tuning beyond the standard profiles we offer for black and clear.
