All or part of the bottom layer of the prints cannot adhere to the build plate

  • Before printing, confirm whether the ambient temperature is higher than 20°C.In winter, because the indoor temperature is very low, the viscosity of the resin increases, which is not conducive to 3d printing.If this is the case, it is recommended to put the resin bottle in hot water at 60~80℃ for 10 minutes before printing.

  • Check if the FEP film is loose.Flick the FEP film with your nails, if it makes a crisp sound, it means it is no problem.

  • Maybe the exposure time of the bottom layer is too short. It is recommended to double the bottom exposure time(No more than 100s) and print again.

  • If the bottom exposure time is set to 100s and the problem cannot be solved, it is recommended to level the build plate.Place the A4 paper between the build plate and the LCD screen, press the plate with your hands and tighten the screws in diagonal order. (as shown below)

  • If the above does not solve the problem, please level the build plate again.Press plate directly on the LCD screen (without A4 paper,as shown below)

  • If this does not solve the problem, it may be that the light-shielding tape on one side of the LCD screen is against the build plate, causing the difference distance between the two sides of the plate and the LCD screen. If it is, it is recommended to remove the tape or replace with thinner shading tape(as shown below)

  • If the above does not solve the problem,this is probably a problem with the mechanical structure. After the plate is locked, one side of it tilts up. (as shown below)

  • The solution is as follows:

  • If the above does not solve the problem, it may be due to uneven build plate or LCD screen. Increase the exposure time of the bottom layer,or replace the uneven part, or add a certain proportion of transparent resin with faster curing speed to the resin before printing.
