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

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 manufacture 1.75mm and 2.85mm diameter filaments in a range of spool sizes.

Generally speaking, PP is difficult to print with - as a semi-crystalline polymer it can warp when used for 3D printing. As a result, Forefront has engineered its filaments, modifying the polypropylene with ethylene, matching the unique property set of polypropylene with the demands of the 3D printing process.
