Why Are Partial Supports Missing?

1. What’s Wrong with My 3D Print?

When inspecting the 3D print, you notice that some of your supports have failed to print, leaving the raft smooth and clean.

2. What Causes the Printing Issue?

While this printing issue seems similar to the Support-Breaking Issue, it is caused by vastly different factors. Supports failing to print are usually caused by a sudden change of suction force or a slicing issue.

3. Troubleshooting the Printing Issue

Resolving this issue requires checking to see if the sliced files are normal and adjusting the support setup. The following steps are organized in order of likelihood to identify and resolve the printing issue:

Adjusting the resin profile settings

• Check out the Official Resin Profile and make sure you’ve dialed in your resin correctly
• Adjust the light-off delay time correctly.

Adjusting support settings

• Toggle to “Raft” at the supports column
• Set the raft thickness and raft height at the same value

Checking sliced files in Chitubox

• Click the “Slice” button on the right side
• Then toggle through the bar on the right and check the layers after the bottom layer count; e.g., if you have set the bottom layer count at 6, please check layer 7 and see if the supports are shown in that layer.

Light-off delay time is essential in resin 3D printing. With the correct settings, each layer will be printed in a much more stable manner, resulting in better quality 3D prints. Please refer to this article to learn more about Light-Off Delay.
