The best option is to tape a sheet of PP packing tape to your bed — PP only sticks reliably to itself. Alternatively, use a PP-compatible adhesive sheet. Print at 230–240°C nozzle, 90°C bed, and 30–40mm\/s. Use a brim of at least 10mm. An enclosed printer significantly reduces warping. PP-T warps less than pure PP thanks to the talc filler, but it still warps more than PLA or PETG.\u003c\/p\u003e\n\n  \u003ch3\u003ePro Tips\u003c\/h3\u003e\n  \u003cp\u003ePP cannot be glued with standard adhesives — most glues simply don't bond to its surface. For multi-part assemblies, design mechanical joints (snap-fits, press-fits, screws) instead of relying on glue. PP also cannot be painted without a specialty PP primer. These limitations sound frustrating, but they're actually the same properties that make PP so chemically resistant — if solvents and chemicals can't bond to it, neither can glue or paint.\u003c\/p\u003e\n\n  \u003ch3\u003eBest Applications\u003c\/h3\u003e\n  \u003cp\u003eChemical-resistant containers, living hinge boxes, food-safe prototypes, medical device prototypes, automotive fluid reservoirs, battery cases, laboratory equipment, waterproof enclosures, snap-fit containers that need to survive thousands of open\/close cycles, and any application where chemical resistance and fatigue life are critical.\u003c\/p\u003e\n\n  \u003cp\u003eFor the 2.85mm version, see below.
