Warping - Print-Stress
Print-Stress Warping
Parts bowing during thermal curing.

Large XY cross sections bow away from their platform-facing surface.

Cause - Orientation
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.

Internal stresses are created in large XY cross sections during printing that are released during curing.
- Most prominent with large, thin cross sections on the platform. The platform itself further constrains the part, amplifying the print stress.
- More common with rigid two-part resins. Print-stress warping occurs in large XY cross sections with resins that have a high cross-link density in their green state: commonly seen with rigid two-part resins. As the material builds its end-state polymer network in the thermal curing process, the UV network built in the green state breaks down and those stresses are released.

Root Issue | Problem | Why Defect Presents |
---|---|---|
Orientation | Large, thin cross section on the platform | The platform constrains the part. With resins that have a high cross-linked density in their green state (ie during printing), that constraint builds high stress that is released during thermal curing. |
