Dynalabs PP-T Polypropylene Filament 2.85mm 1kg

Dynalabs PP-T Polypropylene Filament 2.85mm — Chemical-Resistant PP for Ultimaker Printers

Polypropylene filament in 2.85mm format is extremely rare — most manufacturers don't even offer it. The Dynalabs PP-T 2.85mm fills this gap for Ultimaker and Lulzbot users who need polypropylene's unmatched chemical resistance, fatigue life, and food-safe properties. Available in Natural (translucent white) at $15.42 per kilogram with free shipping across the USA.

This is the same talc-modified polypropylene formulation as the 1.75mm version, engineered for improved printability over pure PP. The 2.85mm diameter offers an advantage for PP printing — the stiffer filament feeds more reliably through Bowden tube systems, reducing the feeding issues that can occur with softer PP filaments.

Key Specifications

Recommended Print Settings

For Ultimaker printers, create a custom material profile: 235°C nozzle, 90°C bed, 35mm/s print speed. Apply PP packing tape to the build plate for reliable adhesion — PP only bonds to itself. Retraction: 5–7mm at 25mm/s. Enable a 15mm brim. The Ultimaker S5's enclosed build volume helps significantly with PP warping. For Cura settings, set the initial layer speed to 15mm/s and initial layer height to 0.3mm for the strongest first layer bond.

Pro Tips

The Natural color in PP is semi-translucent, which makes it useful for prototyping containers where you need to see the fill level. PP's low density (1.05 g/cm³) means your printed containers are noticeably lighter than identical PLA or PETG versions — important for packaging prototypes where shipping weight affects costs. If you're prototyping injection-molded PP products, 3D printing in actual PP gives you the most accurate material behavior testing possible.

Best Applications

Prototyping injection-molded PP products, chemical-resistant laboratory containers, food packaging prototypes, medical device testing, Ultimaker-based research environments, and any professional application requiring polypropylene's unique properties in 2.85mm format.
