Why Do 3D Prints have Voxel/Pixel Lines?

1. What’s Wrong with My 3D Print?

Have you ever noticed that after cleaning your 3D Prints, you can still notice some circular/linear lines on your models? This is a very normal phenomenon in resin 3D printing. Let’s find out what causes the voxel/pixel line issue as well as how to improve it.

2. What Causes Voxel/Pixel Lines on Models?

While it may initially appear that a hardware problem is causing the issue, the presence of voxel lines is, in fact, attributed to the square pixels on the LCD screen of the printer. This configuration leads to non-smooth surface finishes rather than being indicative of a hardware malfunction.

3. Troubleshooting the Voxel Line Issue

To address the voxel/pixel lines issue, adjustments to advanced settings in your slicer may be necessary. The following steps are organized in order of likelihood to identify and resolve the printing issue:

Adjusting advanced settings in slicer

• Turn ON Anti-Aliasing Function
• Set Values at 4, 0, 4
• Turn Off Image Blur

Reorienting models

• Tilt models in the X and Y Axis by at least 15 degrees and not more than 45 Degrees.
• Refer to this article to learn “How Angles of Models Affect Surface Quality”
