After this, make sure to wipe down the surface, so it is entirely free of any sanding dust and other debris.
Why is my resin print cracking?
When SLA printed part shrinks due to ongoing curing, cracks typically occur at spots where the biggest stresses arise. For example, such spots can be sudden transitions from thick wall to thin wall like “T” joints, i.e. when thinner wall is somewhat perpendicular to the thicker one.
