--- title: "Encrust: a free resin slicer for MSLA and SLA printers" description: "Free, open-source resin slicer with auto supports, hollowing and a layer check that finds islands and suction cups before you print. No account, no cloud." url: "https://encrust.app/" lang: "en" updated: "2026-10-03" --- Resin slicer for MSLA and SLA printers # The resin slicer that answers to you. Supports, hollowing and a layer-by-layer check that catches a failed print before it costs you resin. Free, open source, and your files stay on your computer. [ Download](https://encrust.app/download/) [ Source code](https://github.com/vvvlladimir/Encrust) ## From model to printer in one window. Pick your printer from 100 profiles, scroll through every layer before you commit, and send the file straight to the printer if it’s on your network. ![Encrust's Prepare view: the Encrust logo on the build plate of an Elegoo Saturn 4 Ultra, with the layer slider and the Slice to .goo button.](https://encrust.app/_astro/prepare.BCvbU3bc_25T2Tt.webp) **Prepare.** Choose your printer and resin, drop the model on the plate, and slice it to the file your printer reads. ![Encrust generating supports: the Encrust logo held up by 118 branching supports, with the support settings and the Generate supports button in the side panel.](https://encrust.app/_astro/supports.BX42VLV3_XFUe.webp) **Supports.** Automatic supports branch into shared trunks, so fewer of them reach the plate. Every setting can be tuned by hand, and if a support has nowhere to stand, Encrust tells you. ![Encrust hollowing a model: the cut-away mask shows a 2 mm wall, and the panel reports of resin saved.](https://encrust.app/_astro/hollow.BoNCuFKU_Z1KMLlW.webp) **Hollow.** Hollow a model to the wall thickness you want and see right away how much resin you save. ![Encrust's Preview view: a dragon model beside its layer mask, the layer slider marked with 66 issues, and the resin volume, weight, price, print time and peel forces in the side panel.](https://encrust.app/_astro/slice.Ccd3ngvT_Zh3pGM.webp) **Preview.** Scroll through every layer next to the model. Resin, cost and print time are already worked out, and anything the check found is marked on the slider. ## Everything a resin print needs, in one app. No plug-ins, no separate tool for supports. Every step leaves a file you can open and check. 1. **Send** 20+ formats, SDCP and PrusaLink 2. **Check** Islands, suction cups, thin walls 3. **Slice** Adaptive layers, anti-aliasing 4. **Support** Branching trunks, rafts, painted areas 5. **Hollow** Infill, drain holes, trapped resin 6. **Orient** Auto-orient, arrange, several plates 7. **Repair** Holes, broken edges, flipped faces 8. **Import** STL, OBJ and 3MF, with textures ## Find the failed print before you print it. Encrust reads back the file it just wrote and checks, layer by layer, what will actually cure. Every warning comes with the measurement behind it. - **Islands**: Parts that start in mid-air, with nothing underneath to hold them. - **Suction cups**: Closed hollows that tug on the film every time the plate lifts. - **Thin sections**: Walls and pins likely to tear off on the way up. 100 printer profiles from 14 makers ## 1 of 100 confirmed. Yours could be next. Each block is a printer, drawn to the size of its build volume. The lit one has already printed a file from Encrust. One test print from you lights up the next. - Anycubic 19 - Elegoo 16 - Creality 15 - Phrozen 13 - EPAX 8 - FlashForge 8 - Nova3D 5 - Peopoly 4 - QIDI 4 - Wanhao 3 - Prusa 2 - Kelant 1 - UniFormation 1 - Voxelab 1 [Report a test print](https://github.com/vvvlladimir/Encrust/issues/new/choose) [Find your printer](https://encrust.app/printers/) ## Where it stands, honestly. 1 /100 printers confirmed by a real print so far: the ELEGOO Saturn 4 Ultra. The other profiles are built from the makers’ specs and should be close. Start with a calibration print. \~1,500 tests run on Windows, macOS and Linux with every change. 20+ file formats, and every file is read back to check it. 0 accounts, trackers or crash reports. Your projects are plain files. Alpha Keep your current slicer installed for now. ## Start with a calibration print. Worst case, you lose a few hours and a few millilitres of resin.
