How to calibrate your resin 3D printer?

1) Why is "normal layer exposure time" the most important parameter to calibrate?

Exposure time is the most important factor in print quality. Too much exposure time will "overcook" the resin and make your print blurry. Too little exposure time will not make a layer of resin "stick" to the previous layer, making your print partially or totally fail. Therefore, we need to find the perfect balance between over-exposure and under-exposure.

2) When should I do an exposure time test?

We advise you to do an exposure test each time you change your printer or resin, and when there is a big change in weather in your region.

We recommend ABS-like resin because it's tougher and more flexible

3) How should I do an exposure test?

We recommend the cone exposure test to find the optimal normal layer exposure time for your printer / resin.

Step 1) Download and print the cone exposure stl file using your usual printer settings (no need to add support)

Step 2) Observe both sides of the print

The calibration print has 2 sides, the "Success" side and the "Failure" side

On the "Success" side, ALL cones should print perfectly like on the picture. If some cones did not print, it means that the normal layer exposure time you used was too short. Please print the same test again with higher exposure time. If your success side looks like this picture, then let's continue looking at the "Failure" side.

On the "Failure" side, ALL cones should FAIL to print like on the picture. If some of the cones did print, it means that the exposure time you just used was too long. You can get better printing results by reducing the exposure time and try to print it again.

Step 3) When you find the optimal normal layer exposure time, you can input the number in the "Printing File Export Request Form"
