Native MSLA slicer · Early access
Written in Rust with its own GPU viewport. Tree supports and voxel hollowing that run at full speed, a layer view you can actually read. Nothing in a browser tab, nothing waiting on a spinner.
The whole job lives in one tab bar, in the order you actually work. These are real captures of the app, and every time on this page was measured on one real run with the model below: scroll and the run plays back.
01 · Transform
Press G, R or S and drag. A live chip reads distance or degrees as you go, and axis guide lines keep you honest. Or type it in the numeric inspector: position, lift, rotation, size.
0.39 s to open a 92 MB, 1.9-million-triangle miniature
02 · Hollow
A translucent cavity preview that follows the wall slider live, a Recommended thickness one click away, fine ±0.1 and ±1 mm steps, and drain holes before or after.
0.87 s for the live cavity. Meanwhile the supports are being made in the background.
03 · Supports
Trunks, branches, leaves, braces and rafts, prepared in the background while you worked, so Generate is often instant. Add with A, remove with X, with a live preview before every click.
0.15 s from Generate to the supports on screen: they were ready before the click
04 · Slice
Print time, resin and weight. Then a split view that zooms to 32× with crisp, honest pixels. Sealed cavities slice correctly: what you see is what gets exposed.
0.66 s to slice 991 layers
05 · Export
The file your printer reads, written before you can blink: every layer is encoded on every core, and the bytes are the same as a careful one-layer-at-a-time write. Your project keeps its state, so a last-minute fix is one tab away.
0.12 s to write the 26.9 MB printer file, every layer encoded on every core
Four short recordings of the app at work, on the same miniature. The small things that make an evening of preparing prints feel quick.
Move with G, rotate with R, scale with S, and lock any of them to X, Y or Z. A chip reads the distance, degrees or scale as you go, and the plate turns red the moment the model leaves it.
With A a green support follows the cursor, already routed to the plate. With X everything that would go turns red. One undo per click.
The translucent cavity follows the wall setting as you change it: ±1 and ±0.1 mm steps, and a Recommended thickness for this model one click away.
A real layer of this miniature at the printer’s own pixels (19 µm on a Saturn 3 Ultra). Zoom to 32× with no smoothing: what you see is what the screen exposes.
Why native
Most desktop apps today are a website in a window: a whole browser engine shipped inside, sitting between you and your model. Every click goes through it. We wrote Breadslicer from scratch in Rust, with its own GPU renderer, so nothing sits in between. You feel it in the first second, and in every second after.
Then 0.39 s to open a 92 MB, 1.9-million-triangle miniature. No splash screen to watch.
On our 16-core test machine, 991 layers are encoded at once and written in 0.12 s. Supports are prepared on the spare cores while you look at the cavity.
A single executable that talks to the GPU through DirectX 12, Vulkan or Metal, directly.
A walk-through that gets exposure right for a new resin without a spreadsheet.
Force-based analysis that flags supports likely to fail before the print does.
Pull a pre-supported file apart into model and supports so each can be edited on its own.
Report from inside the app, with the context attached, straight to the people who fix it.
Breadslicer is in early access. Builds are being handed out in small batches. The download will appear here, and so will the Discord.
