Why did Some Part of the Print Become Flat Disks?

What’s Wrong with my Resin 3D Print?

When inspecting your 3D print, you notice that some parts of your 3D print have failed to print correctly and instead have become flat disks hanging in mid-air.

What Causes the Issue?

Similar to prints falling off from its supports, this usually means that the supports are not strong enough and have failed to hold onto parts of the resin 3D model.

Troubleshooting the Model Cracking Issue

Resolving this issue requires adjusting several settings on slicing software and redialing your resin before adjusting the supports. The following steps are in the order of the most likely cause of the issue:

Adjusting the Resin Profile Settings

  1. Check out the official resin profile and make sure you have dialed in the resin correctly.
  2. Increase normal layer exposure time by 10%.
  3. Lower the lifting speed to below 40 mm/min.
  4. Make sure your light-off delay time is set according to this auto-calculator.
Make sure lift height is set according to our official resin profile.

Adjusting the Support Settings

  1. Increase the Upper Diameter and Support Density. For suggested values, please refer to this article.
  2. Avoid setting supports on a flat surface. Instead, rotate your model on both the X-axis and Y-axis.
  3. Avoid printing your model at an angle that may cause the formation of a suction cup as the model faces the resin vat. If that is the case, make sure to rotate your model or add drain holes to your 3D print.
  4. If it is a hollowed 3D model, make sure the wall thickness for small prints is set at 1.5 mm or above, while wall thickness for large prints is set at 2 mm or above. Then add at least 2 drain holes that are at least 3 mm wide to the bottom of the 3D print.
