3D printing filaments for non-brittle, waterproof parts with form and function - engineered performance, made from polyolefins (polypropylene and polyethylene).

Compatible with a wide range of filament 3D printers, and designed to be used in engineering and home-use applications, our filaments are water and moisture resistant, are clean and easy to print with, are recyclable and are made in the UK. We sell 1.75mm diameter filaments in 130m spools, which hold 10% more filament than a typical 0.5kg spool of PLA.

Polyolefins (Polypropylene PP & Polyethylene PE) are used and trusted the world over in food packaging, sports clothing and medical applications, to name a few. Forefront has engineered the unique property set of polyolefins into a range of filaments specifically for 3D printing, then matched them to a bed plate material (supplied with the products) to create a unique 3D printing system.

Launched in 2016, Forefront's 3D Print Filament range includes:

  • Forefront F43 TOUGH™ - a tough high-performance 3D printing filament for high quality, impact, moisture and chemical resistant parts - great for engineering models and functional parts including living hinges and can withstand temperatures up to 100°C

  • Forefront F41 FLEX - a flexible high-performance 3D printing filament offering the same benefits as the 43 Tough filament but with flexibility and excellent 'memory' for printing flexible parts, hinges, seals and shock-absorbing components or elements with no stress whitening.
