Photon File Validator 2.1

Photon File Validator is a utility for resin 3D printing that checks sliced build files before you print. It loads .photon and other common MSLA formats, provides a fast layer-by-layer preview, and highlights error-prone regions such as islands and other unsupported areas. By surfacing problematic layers and visualizing support coverage, it helps you catch issues early, reduce failed prints, and save time and resin.

Key capabilities:

• Layer-by-layer visualization to verify orientation and exposure
• Detection of islands/unsupported pixels with per-layer indicators
• File insights such as model size and layer count
• Non-destructive validation so you can fix issues in your slicer of choice

Photon File Validator is developed by Bonosoft. The most popular versions of this product among our users are: 1.4, 1.5, 2.0 and 2.1. The name of the program executable file is photonfilevalidator.exe.
