PRINTING UNIT FOR 3D PRINTING BY HIGH-TEMPERATURE POLYMERS BY FDM TECHNOLOGY

摘要

The utility model relates to the manufacture of three-dimensional physical objects by layer-by-layer deposition of polymeric materials, including high-temperature polymers, and can be used in the manufacture of ZV-models of a wide scope of their subsequent use, in particular science, education, industry, medicine, etc. Technical result use of the claimed utility model is to improve the reliability of the 3D printing process by high-temperature polymers. The technical result achieved is The fact that the pinch rollers are made in the form of gears, mounted on the ends of the angle lever and mounted to engage with the gears, and each extruder is equipped with a liquid radiator, while the filament feed channel passing through the radiator and thermal barrier is a hollow cylindrical ceramic the tube and the nozzles of the extruders are made of wear-resistant titanium alloy, and the radiator and the feed mechanism are enclosed in a thermally insulating housing.
