Encrust is a free, open-source slicer for MSLA and SLA resin 3D printers. It checks every layer of the file it writes for islands, suction cups, thin walls and hard peel before you print, and that check runs in the same pass as the slice: a million-triangle model is sliced, written and checked in 0.72 seconds on an eight-core computer.
Supports, hollowing, drain holes, auto-orientation and a command line are all included. There's no paid tier, no account and no cloud, and your files never leave your computer. Encrust runs on Windows, macOS and Linux, and in the browser at encrust.app/app.
Encrust is in alpha. The whole pipeline works and has printed real parts, but only one printer (ELEGOO Saturn 4 Ultra) is confirmed so far. Start other printers with a small calibration print.

Features
- Checks every layer of the written file for islands, suction cups, thin walls and hard peel
- Fixes issues in one press: supports every island, removes islands, drills suction cups
- Sliced, written and checked in 0.72 s for a million triangles (8-core computer)
- Auto supports sized by load, with branching trunks, rafts and painted areas
- Hollowing with infill, drain holes, flush-fitting plugs and trapped-resin detection
- Auto-orientation that counts islands at your printer's resolution
- Writes 20+ printer formats (.goo, .ctb, .pwmx, .sl1, .cxdlp and more) and reads each one back
- Sends to Elegoo/Chitu (SDCP) and Prusa (PrusaLink) printers over your network
- Imports resin settings from another slicer's sliced file or a .cfgx/.ini profile
- Command line for scripts and batch slicing, with JSON output
- Runs offline. No account, no cloud, no paid tier
