SuperSlicer Download: Free PrusaSlicer Fork with Calibration Tools

Download SuperSlicer

How this download box works

• It is live. Each visit asks GitHub for the release it marks as the latest stable one in the official supermerill/SuperSlicer project. Your browser keeps the answer for ten minutes; the Refresh button asks again straight away.
• Why it shows a 2024 build. GitHub’s “latest” release is still version 2.5.59.13 from July 2024. Every newer build, from 2.5.60.0 to the 2.7 series, is marked as a pre-release, so the box does not list their files, and it mentions the newest one in a notice instead. The next section helps you choose.
• Mac files: there are separate files for Apple Silicon and Intel Macs. Linux files: two AppImages (a standard one and a GTK2 one) and an archive. Windows: a zip you extract; there is no installer in the stable release.
• No checksums for 2.5.59.13. GitHub shows SHA-256 checksums only for the 2.7.61.5 and newer builds, so the stable files in this box have none.
• Every link goes to GitHub. The script only accepts download addresses on the official project’s release path. If GitHub cannot be reached, the box falls back to links that always point to the newest release.

Download Safety

Slicers run with full access to your files, so where the installer comes from matters. SuperSlicer’s README points to its GitHub releases page for prebuilt Windows, Linux and macOS builds, and mentions package managers (Chocolatey, Scoop, Homebrew and Arch Linux). The download box above reads from that same releases page. At the time of writing, the project’s website (superslicer.org) has an expired security certificate, which makes browsers show a warning, and its news and links pages are out of date, so this page does not rely on it.

Binaries are not signed. The release notes tell Windows users to say to the operating system that they trust the program, and tell Mac users how to remove the quarantine flag. The developer wrote in March 2026 that a Mac malware warning was not malware: the build was simply not signed with a certificate. Download only from GitHub, and compare checksums when a build has them.

Check the SHA-256 checksum (builds that have one)

A checksum is a fingerprint of the file. For builds that carry one (2.7.61.5 and newer), if the fingerprint of your download matches the one shown on the release page, the file is exactly what was published. Replace the file name with yours.

Which SuperSlicer Version Should You Download?

The facts first, as of 18 October 2026. All dates are the GitHub publication dates.

Is SuperSlicer still being developed?

The developer has not published any statement that the project is halted or abandoned. What can be checked: no release has been published since 19 November 2025; the default branch’s last commit is dated 18 November 2025; but other branches have been active in 2026 (a commit on the dev_3_0 branch dated 8 October 2026, and GitHub “release candidate” build runs on 6 September 2026); and the developer’s last issue and pull-request comments date from March 2026. A community discussion on the project’s GitHub page asks for a status note in the README; at the time of writing the developer has not replied there. The roadmap the developer published in March 2025 planned a feature release (2.7.62) followed by a catch-up with PrusaSlicer 2.9.

Our suggestion

• You want the program that GitHub calls stable and don’t mind its age: use 2.5.59.13 from the download box above. It is what most people have installed (the Windows zip has been downloaded about 70,000 times) and the project’s own links page still names it as the latest stable version.
• You want the newer features and accept pre-release quality: open the releases page (the link in the box) and choose 2.7.61.10, the last 2.7.61 build, or the 2.7.62.0-beta2 if your system is covered. Keep a copy of your settings first; versions can change profile formats.
• You want a maintained slicer with the same roots: PrusaSlicer (the parent project) and Orca Slicer are actively released; see the comparison below.

What Is SuperSlicer?

A slicer is the program between a 3D model and a printer. It cuts the model into thin layers, works out the path the nozzle should follow for each one and writes those instructions as G-code. SuperSlicer (previously called Slic3r++) takes STL, OBJ and AMF models, and 3MF and STEP files, and turns them into G-code for FFF printers or PNG layers for mSLA resin printers. The README says it is compatible with any modern printer based on the RepRap toolchain that runs a firmware such as Marlin, Prusa or Klipper.

Lineage and licence

The README describes it as “a PrusaSlicer fork (which is a Slic3r fork)”. It is released under the GNU Affero General Public License v3, and GitHub lists it as a fork of prusa3d/PrusaSlicer. The developer’s own wiki, in a page dating from 2020, says it has nothing to do with Prusa Research and is a personal fork for the developer’s own use. SuperSlicer is not a fork of Orca Slicer or Bambu Studio, though it has borrowed some ideas: Bambu Studio’s arc-fitting algorithm arrived in version 2.5.59.2, and Orca-style small-area flow compensation and project import came in 2.5.60.0 and 2.5.59.7.

Accounts and privacy

No official page says an account is required, and the first-run wizard has no sign-in step. The project’s privacy statement on its wiki says the program does not send information to other networked systems unless you request it; the only path is when you launch a print to a printer you configured. The program has a “check for application updates” option that notifies you at startup and does not install anything automatically in the 2.5 line.

What’s New in Recent Releases

The table summarises the 2.5 stable builds and the 2.7 pre-releases, newest first, from the official release notes. SuperSlicer’s version numbers have four fields: the first two follow the PrusaSlicer line that was merged (2.5, 2.7), the third is SuperSlicer’s own counter, and the fourth is the release in that series.

Key Features

The README lists what SuperSlicer adds to PrusaSlicer; the cards below follow that list and the release notes. It also has all the PrusaSlicer features of the version it was merged with (per-object settings, variable layer height, spiral vase, several infill patterns, post-processing scripts, a command-line interface and more).

The Calibration Menu and the Documented Order

The Calibration menu is for FFF printers (it is disabled for resin printers) and comes with its own pages, bundled in the program. The introduction page says to calibrate the printer first, then the filament, then the slicer settings, and the tests should be done in this order:

There is no “first layer”, “max speed” or input-shaping entry in the menu. The wiki pages on individual features date from 2019 and 2020, so check a setting against your version before relying on a page.

Which Printers Does SuperSlicer Support?

The README says SuperSlicer works with any modern printer based on the RepRap toolchain that runs a firmware such as Marlin, Prusa or Klipper, and the repository describes it as a G-code generator for 3D printers (“Prusa, Voron, Creality, etc.”). The bundled profiles are snapshots: they are counted from the profile repository versions each build uses.

No Bambu Lab printers are listed. Network sending uses the Host Type setting in Printer Settings: in 2.5.59.13 the choices are PrusaLink, OctoPrint, Duet, FlashAir, AstroBox, Repetier, Klipper, MPMDv2, MKS and Monoprice, and the 2.7 builds add PrusaConnect and “Klipper (via Moonraker)”. The G-code flavours include Marlin, Marlin 2, Klipper, RepRapFirmware, Repetier, Smoothie, Mach3 and Machinekit. To add a printer, pick a vendor and model in the Configuration Wizard, or use its Custom Printer page (name, firmware, bed shape, nozzle and filament diameters, temperatures). The repository also documents how to write a vendor profile bundle.

Who Should Use SuperSlicer?

• PrusaSlicer users who want more control: the settings and the file menu are familiar, and PrusaSlicer configs and bundles can be imported.
• People who like to tune: thin walls, top surfaces, holes, brims and seams all have extra options.
• Calibrators: the Calibration menu generates test prints and documents the order to run them.
• Experienced users who accept a slower, one-person project: the stable build is two years old and newer builds are pre-releases.

If you want a maintained program with the same family look, see PrusaSlicer or Orca Slicer.

System Requirements

How to Install SuperSlicer

The project has no step-by-step install guide, so the steps below combine its release notes with standard behaviour for each system.

Windows

1. Download the Windows zip from the box above and extract it into a folder. The notes name superslicer.exe as the program inside. There is no installer in the stable release; a .msi exists only in 2.7.61.10.
2. The build is unsigned. The 2.7.61.0 notes say to tell your operating system that you trust the program, as with earlier releases. Confirm the file came from GitHub first.
3. Portable settings: if a folder named configuration sits next to the program’s resources folder, SuperSlicer uses it instead of the user data folder; the 2.5.59.6 notes also mention the --datadir option.
4. Package managers: the README says Windows users can use Chocolatey or Scoop. The release notes warn the Chocolatey package can lag the release by a few days for validation, so check its version.

   choco install superslicer

macOS

1. Choose the file for your processor: the one with macos_arm in its name for Apple Silicon, the other for Intel. The newest beta has no Intel file.
2. Open the .dmg and drag SuperSlicer into the Applications folder.
3. The release notes say the Intel build asks for permission, while the Apple Silicon one reports that it is “corrupted”, and the fix is to remove the quarantine flag in Terminal. The developer has said the builds are simply not signed with a certificate.

   xattr -cr /Applications/SuperSlicer.app

4. The README lists a Homebrew cask named superslicer; check its version before relying on it.

Linux

1. Download the AppImage (the standard GTK3 build, or the one with gtk2 in its name), make it executable and run it. The 2.7.61.1 notes say the AppImage tool now needs FUSE 3, so install it if the file will not start.

   chmod +x SuperSlicer-ubuntu_*.AppImage
   ./SuperSlicer-ubuntu_*.AppImage

2. Each release also has a Linux archive. The README says the Linux and macOS builds were compiled but not tested by the developer, so report any bugs you find; an Arch Linux package is also listed there.

First-Time Setup and Your First Print

The Configuration Wizard

On first launch the wizard walks through the printer vendor and model (or a Custom Printer), the filaments, automatic updates, reloading models from disk, file associations (Windows only), the view mode (Simple, Advanced or Expert, with an option for inches) and, for a custom printer, the firmware type, bed shape, nozzle and filament diameters and temperatures. Its update page offers a notification at startup and an option to update built-in presets automatically; a backup snapshot of the whole configuration is taken before a preset update is applied.

Bring your PrusaSlicer settings with you

SuperSlicer keeps its own data folder, separate from PrusaSlicer’s. Use File, Import, Import Prusa Config for a configuration exported from PrusaSlicer and Import Prusa Config Bundle for a bundle of presets. A PrusaSlicer project (.3mf) loads, and since 2.5.59.7 a first version of Orca and Bambu project import exists. Back up your own profiles with File, Export, Export Config Bundle. Help, Show Configuration Directory opens the folder; on Linux it is ~/.config/SuperSlicer.

Do not share one configuration folder between different SuperSlicer versions: the 2.5.59.6 notes warn that an older version can erase newer settings when it saves a profile. The 2.7.62 beta solves this with a separate folder per version.

Slice and print a model

1. Add a model. Drag a file into the window or use File, Import.
2. Calibrate first, in the documented order (see the calibration section above), and save the results in your filament and printer presets.
3. Check the three presets (print, filament, printer) and the view mode, then arrange and orient the model.
4. Slice and read the preview, then export the G-code, export it to an SD card or flash drive, or send it to a configured print host.

SuperSlicer vs PrusaSlicer and Orca Slicer

These three share a lineage, so the choice depends on how much you value extra settings against active development.

Orca Slicer’s README lists SuperSlicer among the projects it drew ideas from, and Orca has ported SuperSlicer features such as mouse-ear brims and polyholes. If you like SuperSlicer’s ideas but want a maintained program, Orca Slicer is the usual alternative.
