    The ceramic heatbed of 3DGence DOUBLE P255 printer ensures good adhesion of basic printing materials. However, there is a wide range of commercially available solutions improving adhesion of printout to heatbed for difficult-to-print materials. Grease and dirt on the heatbed have detrimental impact on adhesion.
  • Page 60 – optoelectronic switch that restricts the 3D printer movements to the allowable limits. 3DGence DOUBLE P255 printer is equipped with 3 optical endstops – one for each axis. The optical endstop does not require the physical contact with the corresponding breaker, which guarantees its long life. However, attention should be paid to its sensitivity to sources of bright light, which can cause false activation.
  • Page 61 3DGence Slicer software recognizes these surfaces and analyses the angle of overhang relative to the heatbed. If the angle exceeds the boundary angle defined in the software, 3DGence Slicer will automatically generate support structures under such a surface.
  • Page 62 Support (supports) – a "support" added by the designer of the model or the slicing software (3DGence Slicer) on which parts of the model suspended in the air are based. Properly made support is not a part of the model and can be easily separated from the finished printout.
