Shrink Line
Shrink Line
Lines on the part surface corresponding to changes in geometry.

Shrink lines can be diagnosed as follows:
- Lines correspond to a feature change in the geometry.
- Lines can appear in any direction relative to the build platform.
- Lines do not have a sharp edge.
- Lines can often be seen but not felt.Cosmetic only

Cause - Cross Section
Solution - Print Preparation or Part Design
The following solutions will address print or part-related causes of the defects. Choose among the suggested actions below and select the best approach for your application. Usually only one type of adjustment is needed.
If problems persist, please reach out to Carbon Support.
- The process of polymerization produces heat as each slice cures.
- Slices cool after initial cure.
- Cooling rate is determined by cross section.
- When cross section changes due to a feature change in the geometry, cooling will occur at different rates where the geometry changes.
- Smaller cross sections cool more quickly than larger cross sections.

Root Issue | Problem | Why Defect Presents |
---|---|---|
Cross Section | Cross section changes suddenly | Smaller cross sections cool more quickly than larger cross sections. When a sudden change in cross section occurs between slices, the change in cooling can manifest in a surface finish difference. |
