Forward AM Ultrafuse PP (formerly BASF) is an industrial polypropylene filament suitable for functional prototypes, chemically resistant parts and mechanically stressed components. It offers low density, excellent fatigue strength and outstanding chemical resistance - all in combination with printing on standard FFF printers.

Industrial polypropylene for demanding applications

Ultrafuse PP is an engineer-grade material developed for parts that must withstand mechanical stress, cyclic loading and aggressive chemical environments. It finds use in automotive, chemical industry, packaging technology and everywhere the combination of strength, toughness and resistance is key. If you need an alternative to other technical materials, also check out our category of nylon filaments or polycarbonate.

Excellent chemical resistance

Polypropylene is one of the most chemically resistant thermoplastics available for FFF printing. Ultrafuse PP resists aggressive solvents, acids and bases, which predestines it for containers, sumps, connectors and components for handling liquids. Parts made of PP thus find use in laboratory environments as well as in chemical operations.

Low density and low part weight

PP has a density below 1 g/cm³ - i.e. it is one of the lightest thermoplastics. Thanks to this you get a strong yet extremely lightweight part, which you will appreciate for jigs, fixtures, portable parts and wherever weight saving is essential compared to PLA or PETG.

High fatigue resistance and toughness

Ultrafuse PP withstands repeated mechanical stress without fatigue failure. Elongation at break reaches up to 118.6 % in the XY direction, which indicates excellent ductility and impact absorption capability. The material is therefore ideal for living hinges, flexible clips and components exposed to vibration.

Recyclable and sustainable

The filament is fully recyclable and is supplied on recyclable spools in eco-friendly packaging. Forward AM thus brings a compromise between industrial performance and sustainable production - an important factor for companies with ESG goals.

Easy printing on standard FFF printers

Ultrafuse PP prints without the need for an enclosed chamber at a nozzle temperature of 220-240 °C and with a heated bed at 60-80 °C. The key to success is a suitable print surface - PP tape or PP glue, which eliminates warping and ensures firm first-layer adhesion. We recommend a nozzle with a diameter of at least 0.4 mm.

Wide print speed range

The material handles print speeds from 20 up to 300 mm/s depending on the profile and machine. For the highest speeds it is advisable to slightly increase the nozzle temperature. Forward AM also offers ready-made print profiles for Ultimaker, Prusa, Raise3D and Bambu Lab.

Typical applications

Ideal for chemical containers, laboratory aids, packaging prototypes, clips and clamps, automotive parts, as well as jigs and fixtures in manufacturing, sealing elements and lightweight functional parts. If you are looking for an alternative with higher stiffness, also consider ABS or ASA. For elastic parts, the category of flexible filaments is suitable.
