overview fpu 50 (flexible polyurethane) is a rigid 2 part resin that is unique in the additive industry, with properties similar to polypropylene offering high impact strength and cycle life, it is designed to withstand repetitive stresses resource links about the material material overview and uses cases technical data sheet mechanical properties and data safety data sheet login required protocol sheet this downloadable pdf provides important usage information, including instructions about hardware storage resin dispensing & printing washing curing example protocol sheet print it out and bring it into the lab english https //archbee doc uploads s3 amazonaws com/uxbzokjjtgpphjapq8fvm ye5jh3mgemuab5r15 ozc 20250521 011822 pdf spanish/español https //archbee doc uploads s3 amazonaws com/uxbzokjjtgpphjapq8fvm iphg7m5yaxvtfgwwc2lcc 20250129 165351 pdf german/deutsch https //archbee doc uploads s3 amazonaws com/uxbzokjjtgpphjapq8fvm dmz9vsvemzpq7stzcgoar 20250129 165411 pdf japanese/日本語 https //archbee doc uploads s3 amazonaws com/uxbzokjjtgpphjapq8fvm zqmxd51ocurdrmzpf6nhg 20250129 165457 pdf resin dispensing fpu 50 must be stirred after dispensing and between every print while all resins require stirring to check the window for bits of cured resin between prints, fpu requires more vigorous stirring to ensure proper mixing of the part a & b components comprising the liquid resin fpu 50 parts can sometimes exhibit small, localized regions of reduced toughness due to the part a & b components settling between prints stirring the resin mitigates negative effects to the material properties curing no uv flash before salt baking some resins recommend a short uv flash curing prior to salt baking this process is not recommended with fpu 50 additional uv light after printing can cause brittleness in fpu 50 to maintain fpu's remarkable ability to withstand repetitive stress with its flexibility, it is important to limit uv exposure to only the printing process the uv light used to shape fpu parts in printing is carefully calibrated to maintain material properties in the final part
