Testing & processing disclaimer
High Heat Deflection Temperature HDT 3D resins despite being rigid tend to be fragile and have a short lifetime, degrading thermally at high temperature. If durable materials with high HDT are needed it is recommended the use of machined polyimide, or injecting PolyAmide Imide PAI or other high HDT conventional polymers in metal or 3D printed molds.
Disclaimer
This material is supplied as a professional manufacturing material and is not marketed as a finished medical device. Final part performance and suitability must be validated by the user according to the intended application.
This technical datasheet should be used together with the relevant processing, calibration, safety and workflow documentation available in the 3Dresyns® Resources section.
