Overcuring in resin 3D printing is when the resin gets too much exposure to the light source, causing it to harden excessively. This can lead to issues like a rough surface or extreme lines visible in the print.
Here are some steps you can take to address print overcuring:
-
Reduce the exposure time of the regular layers: Since overcuring is often a result of too much light exposure, reducing the exposure time can help ensure that the resin doesn’t harden more than necessary.
-
Increase the wait time before lift: Increasing the wait time before the build plate lifts can help reduce stresses on the cured resin and allow more time for the resin to settle and properly form the desired shape.
-
Decrease the lift speed and retract speed: Slowing down the speed at which the build plate lifts and retracts can help reduce the chance of overcuring, as it reduces the amount of stress on the part during the printing process.
Remember that it’s important to make changes gradually and monitor the results, as too much adjustment at once can lead to other issues.
If the problem persists, it might be a good idea to check if there is any issue with the 3D printer’s hardware. Make sure that the build plate is leveled and check if there is any wobble in the Z-axis.
