# How to Identify

Solvent Warping can be diagnosed as follows:

- Only **RPU 130** resin is affected by this type of warping
- Parts washed OFF platform

# Explanation & Causes

## Explanation

RPU 130 parts washed OFF platform can absorb solvent unevenly during washing, which in turn leads to uneven off-gassing during thermal curing.
