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.
