Why Do Part of the 3D Prints Become Flat Disks?

1. What’s Wrong with My 3D Print?

Have you noticed that some parts of your 3D print fail to print correctly and instead have become flat disks hanging in mid-air? Let’s find the causes of this issue and learn what we can do to resolve it.

2. What Causes the Printing Issue?

Similar to Prints Falling Off from Supports, the appearance of flat disks usually indicates that the supports are not strong enough and consequently fail to hold onto specific parts of the resin 3D model.

3. Troubleshooting the Printing Issue

Resolving the flat disk issue requires adjusting several settings in the slicing software and redialing your resin before adjusting the supports. The following steps are organized in order of likelihood to identify and resolve the printing issue:

Adjusting the resin profile settings

• Check out our Official Resin Profile and make sure you have dialled in exposure time and lift height correctly
• Increase normal layer exposure time by 10%
• Lower the lifting speed to below 40 mm/min
• Make sure rest time is proper or your light-off delay time is set according to this Auto-Calculator

Adjusting support settings

• Increase support density and the upper diameter of supports (please refer to this article for detailed suggestions)
• Rotate models on both the X and Y-axis (avoid setting supports on a flat surface)
• Rotate models or add drain holes (avoid printing your model at an angle that may form a suction cup as the model faces the resin vat)
• If models are hollow, make sure wall thickness should be at least 1.5 mm (2 mm for large models). Also, add at least 2 drain holes that are at least 3 mm wide to the bottom of the models
