PC+PTFE

Filament PC + PTFE (polycarbonate + polytetrafluoroethylene) is a technical material, aimed at professionals. Characterized by high mechanical and temperature resistance, the material is perfect for making parts with good dimensional stability that have to work at high temperatures. Elements printed from this filament can work at temperatures around 120 ° C. Due to the low values of the static and dynamic friction coefficient, it can be used in the production of sliding elements. Printouts made of PC + PTFE can be machined to obtain a perfectly smooth surface.

Recommended printing parameters:

extrusion temperature: 270-295 ° C;

bed temperature: 90-120 ° C;

printing speed: 40-60 mm / s;

supply: 0-50% (depends on the geometry of the model);

compatible work tables: glass, smooth PEI, textured PEI.

Filament can be printed on both direct and Bowden printers. We recommend that you close the chamber. In case of problems with adhesion, we recommend the use of adhesive preparations. Due to the high printing temperatures, it will be necessary to install a full-metal heatbreak (without a Teflon tube inside). We recommend drying the filament before printing at 110 ° C for at least 3 hours. Use this: Filament dryer.
