    Next, slice the model in the slicing software and generate G-code, which tells Snapmaker J1 how to behave. Finally, the G-code is transferred to the Snapmaker J1 and printing begins on the printer. Snapmaker J1 will heat the molten material and extrude it onto the PEI glass platform and stack it layer by layer to create a 3D object corresponding to the model.

  • Page 46 Fused Filament Fabrication (FFF) technology is very sensitive to temperature. To ensure ideal printing results, place the 3D printer at the recommended ambient temperature. The Snapmaker J1 has a recommended operating ambient temperature of 10 ° C to 35 ° C (50 ° F to 95 ° F) If the ambient temperature is too high, it may affect the printing effect of some filaments (such as PLA), and there is a risk of damaging the 3D printer components.
  • Page 47 Keep the workbench clean and dry.
  • Page 48 Calibration How it works The heated bed and the PEI glass platform on it are the basis for the formation of prints. By leveling the heated bed, you can ensure that the print adheres smoothly to the PEI glass platform. By calibrating the Z-axis offset, you can ensure that the left and right printheads always work at the correct and consistent height during printing, avoiding problems such as poor first-layer adhesion, nozzle scraping the platform, and head bumping.
