摘要
FIELD: synthesis technology.;SUBSTANCE: group of inventions relates to the field of synthesis technologies, i. e. fabrication of three-dimensional physical objects by additional deposition (layering) using, in particular, polymeric materials, and more specifically to 3D inkjet printing technologies, auxiliary operations of these technologies and equipment for performing auxiliary operations. way to clean the printhead of a 3D printer involves moving the printhead moving the printer when starting printing or changing the nozzle position from inactive to active one, in which the hole of the activated nozzle is aligned with the hole of the cleaner installed on the holder, after the holes coincide, the internal channel of the cleaner is deformed, then the printer pushes the plastic into the channel, thus equalizing the pressure and temperature of the plastic to the operating state, after cleaning, the nozzle is moved to the working area, while the internal channel of the cleaner stops deforming and captures the plastic, the extruded thread remains in the cleaner or is cut off the edge of the cleaner. Device for cleaning the printhead of a 3D printer for carrying out the method comprising: desktop; mechanism for moving the printhead of the printer, printer print head with plastic nozzles, cleaner placed on the holder. Cleaner of the printer head cleaning device of the 3D printer is designed as a rubber or silicone cap with an internal channel.;EFFECT: pressure and temperature of the plastic melt are equalized at the start of printing or changing the nozzle and at the same time cleaning the nozzle from the flash.;6 cl, 7 dwg
