TECAFIL PC FR natural - 2.85 mm

Flame retardant Polycarbonate Filament

As a leading manufacturer of high performance and engineering plastics, our goal was to find a solution for processing engineering plastics on desktop printers. In order to make engineering grade filaments printable on printers without a heating chamber, we specially developed a polycarbonate filament for Ultimaker printers: TECAFIL PC FR natural.
TECAFIL PC FR natural can be classified as a fire-retardant filament and is available in diameters of 2,85 mm and 1,75 mm.
This polycarbonate filament is intended for applications in the aerospace and railway industry. To meet the special requirements of aircraft interior applications, this PC 3D printer filament was developed based on a flame-retardant polymer. By using flame-retardant additives within an engineering grade filament, we are able to offer an alternative to inherently flame-retardant materials like PEEK, PEKK or PEI. This makes our flame-retardant 3D printer filament a perfect choice for applications like housings, cell holders, brackets or connectors. It can also be a cost-efficient alternative to applications previously made from inherently flame-retardant materials.
3D printed samples of TECAFIL PC FR natural are qualified according to FAR 25.853 (a) and UL94 V-0 by testing the Ultimaker printed components according to market standards and regulations.
Printing polycarbonate is often described as difficult, especially without a heated building chamber. We overcame this challenge by reducing the glass transition temperature of this polycarbonate 3D filament to 80 °C. As a result, this flame-retardant filament can be printed without a heated chamber and the printed components will not warp. The printing of Ensinger's polycarbonate 3D printing filament thus enables perfect layer adhesion with almost no voids, even without a heated chamber.
Our efforts in material development are aimed, among other things, at ensuring ideal mechanical properties. In the process, we have succeeded in optimsing the tensile strength (XY Orientation) of our Ultimaker PC FR filament so that it almost reaches the values of injection molded parts (97 %).
This 3D printing material is a flame-retardant filament, that has been tested according to FAR 25.853 and UL94 V-0.
