A lightweight, chemically resistant material family with demanding bed adhesion and warping behaviour.
Check whether it fits your part
Best uses and poor fits
Commonly selected for
- chemical-contact components
- living hinges
- lightweight parts
Consider another material for
- small unsupported precision parts
- general purpose first prints
Starting setup range
Printing difficulty: advanced. Nozzle: 220-250 C. Bed: 80-100 C.
These are generic starting ranges, not a universal profile. Check the exact spool manufacturer guidance. Enclosure expectation: helpful. Drying importance: low.
Property profile
The five-point ratings are editorial comparison bands for typical unfilled material families, not laboratory measurements.
Stiffness 2/5 · Toughness 4/5 · Flexibility 3/5 · Heat resistance 3/5 · Weather resistance 4/5 · Ease 1/5.
Printing and design cautions
- Strong shrinkage and warping
- Poor adhesion without a suitable surface
- Use a surface recommended for the exact PP spool.
- Plan generous tolerances.
Major limitations and safety notes
- Properties depend strongly on grade.
- Do not infer food-contact suitability.
Use normal good workshop practice and manufacturer safety information. This is generic guidance, not a hands-on spool review or a safety certification.
