Why Did the Model Not Print While the Supports Printed?

1. What’s Wrong with My 3D Print?

When you notice that the bottom layer is stuck onto the building plate, even though the supports have been printed out successfully, the 3D model itself has fallen off from the supports mid print. After dropping into the resin vat, the 3D model is now stuck onto the release film.

2. What Causes the Printing Issue?

That only supports and bottom layers are printed out usually indicates that supports are not strong enough to hold the model. Below are the common causes of the printing issue:

• Incorrect support settings
• Insufficient normal layer exposure time
• Other incorrect parameter settings
• Incorrect model hollowing

3. Before Moving On 

Before moving on, it is necessary to remove any cured resin on the building plate and the resin vat. If you encounter issues while removing cured resin from the release film, please refer to this article.

4. Troubleshooting the Printing Issue

To address the printing issue, adjusting several settings are essential. The following steps are organized in order of likelihood to identify and resolve the printing issue:

Adjusting the resin profile settings

• Check out the Offical Resin Profile and make sure you have dialled in the resin correctly
• Increase normal layer exposure time by 10%
• Lower the lifting speed to below 40 mm/min
• Make sure your Light-off delay time is set correctly

Adjusting support settings

• Increase support density, thickness, and upper diameter (for detailed information, please refer to this article)
• Avoid setting supports on a flat surface. Instead, try rotating models on both the X and Y axis.
• Avoid printing models at an angle that may cause the formation of a suction cup as the model faces the resin vat. Instead, try rotating models and add drain holes.
• If models are hollow, wall thickness for small models should be at least 1.5 mm and large models at least 2 mm. Also, add at least 2 drain holes that are at least 3 mm wide to the bottom of models.

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.
