Usage of PETG in Fillamentum
Fillamentum is a producer of top-quality filaments for industrial applications. No wonder that we have applied our own 3D printed components into production.
Hopper lid
Before a material for filaments is processed it needs to be perfectly dry. The material is dried in the hopper with the metal lid and during drying the temperature can reach up to 70 °C. The original heavy metal lid was replaced with lighter PLA. But this material cannot withstand high temperatures and the lid was twisted by the heat. The new version was printed in PETG that resists high temperatures. At the same time, PETG has a perfect tightness due to minimal shrinkage and excellent dimensional stability.
Cups for collecting hot material
Material is usually mixed with colored masterbatch. When mixing the material one can manipulate with granulate that reaches high temperatures, sometimes up to 75 °C. Mixing takes place in a special industrial box, in which the hot material is poured. For this application, PETG cups are used. PETG is used because of its long-term dimensional stability in high temperatures.
Boxes for moisture extraction
PETG material is, thanks to its dimensional stability, suitable also for applications where there is necessary high tightness. Like the two-parts box which purpose is to get rid of excess water on the surface of the extruded filament. Leaks were causing problems and the extruded filament was not dry enough. PETG is more resistant to water than CPE HG100 that was used for the box originally.
