Polypropylene printed by fused deposition modeling is a semi-crystalline polyolefin thermoplastic extruded from filament and built up layer by layer. Its high crystallization shrinkage makes warping and corner lift common, so printing usually needs a heated bed, a surface it adheres to, and often an enclosed chamber. Parts are anisotropic, with weaker bonding between layers than along the deposited paths, visible layer lines, and marks where supports touch. Voids between beads depend on infill and settings. Printed parts serve as chemically resistant housings, fluid-handling fixtures, living hinges, lightweight jigs, and prototypes of molded parts.
