Snapmaker Orca Download: Free Slicer for Snapmaker 3D Printers

Download Snapmaker Orca

How this download box works

• It is live. Each visit asks GitHub for the newest stable release of Snapmaker’s official Snapmaker Orca project, so you are never sent to an outdated file. Your browser keeps the answer for ten minutes; the Refresh button asks again straight away.
• It shows the current version only. If one system has no file in the newest release, the box says so instead of quietly offering an older build.
• Test builds are flagged, not offered. Snapmaker publishes alpha and beta builds before each stable release. They are marked as pre-releases, may be unstable and are left out of the download list; if a newer one exists, the box mentions it so you can try it if you want.
• The notes are in English. Snapmaker writes its release notes in Chinese and English; the box shows the English text.
• 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.
• Linux has two kinds of file. Current releases include an AppImage for Ubuntu 24.04 and Flatpak bundles for x86-64 and Arm64. Snapmaker’s wiki says the Linux versions have to be downloaded from GitHub.

Download Safety and How to Verify the File

Slicers run with full access to your files, so where the installer comes from matters. Download Snapmaker Orca from the official GitHub release page (the box above reads from it) or from Snapmaker’s own download page, which Snapmaker’s wiki points to. Be wary of mirror and “free download” sites: some show out-of-date version numbers or repackaged installers.

Check the SHA-256 checksum

A checksum is a fingerprint of the file. If the fingerprint of your download matches the one shown in the box above, the file is exactly what was published. Replace the file name with yours.

Windows (PowerShell)

Get-FileHash .\Snapmaker_Orca_Windows_Installer.exe -Algorithm SHA256

macOS (Terminal)

shasum -a 256 ~/Downloads/Snapmaker_Orca_Mac_universal.dmg

Linux (terminal)

sha256sum Snapmaker_Orca_Linux_AppImage*.AppImage

Compare the printed value, character by character, with the SHA-256 shown for that file. If they differ, delete the file and download it again from the official link.

What Is Snapmaker Orca?

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. Snapmaker Orca is Snapmaker’s slicer. Its README calls it an open-source slicer for FDM printers based on OrcaSlicer, and Snapmaker’s wiki describes it as slicing software based on Orca and specifically customised for Snapmaker 3D printers.

On GitHub the project is a fork of the main OrcaSlicer repository, released under the GNU Affero General Public License v3. It keeps Orca’s model handling and slicing and adds Snapmaker’s own work on top: machine, filament and process profiles, and, for the Snapmaker U1, remote monitoring, device management and device control. Snapmaker follows Orca’s releases. Version 1.0.0 Beta was based on OrcaSlicer 2.2.0 Beta, and version 2.2.1 was aligned with OrcaSlicer 2.3.1, so the layout will feel familiar if you have used Orca Slicer.

What’s New in Recent Releases

The table summarises selected stable releases from the official release notes, newest first. The download box above shows the very newest release’s notes live, so it stays current even as this table ages. Some features need a minimum firmware version on the printer, so read the notes for your machine before you update.

The Snapmaker U1’s print presets, machine control and machine management first arrived in the 2.1 series (a beta in September 2025), so the table starts the U1 story at 2.1.1, the first stable release after it.

Key Features

Full Spectrum Colour Mixing Explained

Traditional multi-colour printing changes colour by switching between filaments, say red, then blue, then yellow. Each region of the model uses a single colour, the boundaries between colours are sharp and the palette is limited to the filaments you loaded. Colour mixing works differently: it creates new colours by combining and alternating filaments of different colours. Snapmaker’s wiki gives the examples red plus blue for purple, and yellow plus blue for green.

The principle

Full Spectrum is Snapmaker’s name for multi-colour printing built on colour mixing, designed for the Snapmaker U1. It stacks thin layers of different colours alternately along the Z axis (red layer, blue layer, red layer, blue layer and so on). To the human eye the stack looks like one blended colour, here purple. The thinner the layers, the more often the colours alternate and the smoother the blend, as long as the hardware allows it.

Practical guidance from Snapmaker

• Hardware and software: the guide recommends the Snapmaker U1, the latest firmware and Snapmaker Orca 2.3.6 or later.
• Filament: use filaments with a higher TD value and good translucency, such as Snapmaker’s PLA Full Spectrum bundle. The built-in “Snapmaker PLA Full Spectrum” parameter package suits colour mixing.
• Nozzle and layer height: the 2.3.6 release notes recommend a hot end of 0.4 mm or smaller with a layer height of 0.1 mm or less; a larger nozzle or taller layers can leave visible layer lines. A 0.10 mm colour-mixing process preset for the U1 with a 0.4 mm nozzle was added in that release.
• Safeguards: since 2.3.5 slicing is blocked when you pick an incompatible filament combination in Color Mixing mode, and the slicer warns if Variable Layer Height and Subdivide Mix Layer are on together.

Which Snapmaker Printers Does It Support?

Snapmaker’s wiki has one quick-start guide for the U1 and another for the Artisan, 2.0 series and J1/J1s. The profile package that ships with the program lists these machines:

The U1 gets the newest features first; the 2.0, Artisan and J1 machines are covered mainly by profile and G-code improvements. If your printer is not in the list, use Orca Slicer or the maker’s own slicer.

Who Should Use Snapmaker Orca?

• Snapmaker U1 owners, who get device management, remote monitoring and the Full Spectrum workflow built in.
• Owners of the Artisan, J1/J1s and 2.0 machines, who want maker-supplied profiles and direct Wi-Fi sending from the slicer.
• Colour-mixing experimenters, who enjoy gradients and blended colours and are happy to test settings.
• Orca Slicer users who want Snapmaker’s printers and profiles in one program.

If you print on several brands, you will usually be better served by a multi-brand slicer; the comparison below explains the differences.

System Requirements

How to Install Snapmaker Orca

Windows

1. Download the Windows installer from the box above and, if you like, check its SHA-256 checksum.
2. Run the installer and follow the prompts. If Windows SmartScreen shows a warning, confirm that the file came from the official release and matches the checksum before continuing.
3. Prefer not to install? Use the portable .zip: extract it and run Snapmaker Orca from the extracted folder.
4. If the program will not start, install the two Microsoft runtimes named in the README (the Edge WebView2 runtime and the Visual C++ 2019 x64 redistributable), then try again. Version 2.2.4 also fixed a launch failure in some Windows 11 environments, so update first.

macOS

1. Download the macOS DMG. It is a single universal build, so the same file serves Apple Silicon and Intel Macs.
2. Open the .dmg and drag Snapmaker_Orca.app into the Applications folder.
3. If macOS blocks the app from opening, the README describes three ways to open an app that macOS has quarantined: hold Command, right-click the app, choose Open and confirm; remove the quarantine flag in Terminal; or open System Settings, Privacy & Security and click Open Anyway.

   xattr -dr com.apple.quarantine /Applications/Snapmaker_Orca.app

Linux

1. AppImage (built for Ubuntu 24.04): make the file executable and run it, as the README suggests if it will not start. Some distributions need FUSE support installed for AppImages to start.

   chmod +x Snapmaker_Orca_Linux_AppImage*.AppImage
   ./Snapmaker_Orca_Linux_AppImage*.AppImage

2. Flatpak (x86-64 or Arm64): install the downloaded bundle with Flatpak, then start Snapmaker Orca from your application menu. This is the standard way to install a local Flatpak file; Snapmaker’s documentation does not spell it out.

   flatpak install --user ./Snapmaker_Orca-Linux-flatpak_*_x86_64.flatpak

First-Time Setup and Your First Print

First launch and sign-in

The setup wizard asks for three things: your login region, the printers and nozzles you want listed (the Snapmaker U1 is the default), and the filaments you want in your material list. You can change all of them later from the menu, and reopen the wizard from Help, Setup Wizard. For the U1 you sign in with an email address and a verification code, or an email and password; on first use you register and accept the user agreement and privacy policy.

Bind a Snapmaker U1

1. Choose a mode. Cloud mode works even when the printer and computer are on different networks. LAN mode suits data isolation or a network without internet.
2. Cloud mode, PIN method: on the printer open Settings, Account, and check that the printer’s region matches the software’s. A PIN code appears and refreshes (the countdown is 180 seconds). In the slicer click Add Device on the Home or Devices page and choose PIN code binding, or choose Search Device and authorise on the printer.
3. LAN mode: bind by the printer’s IP address or by searching for nearby devices.
4. Prefer the phone? You can also bind from the Snapmaker App, by scanning a QR code in cloud mode or by IP address or nearby search in LAN mode.

Slice and print a model

1. Create a project and add a model. Use File, Import, the first toolbar icon, or drag the file into the window. Supported formats are 3MF, STL, STP, STEP, AMF and OBJ.
2. Check the three presets. Choose the printer and nozzle size, the filament, and a process preset for quality, strength and speed.
3. Orient the model. Place the flattest face on the plate where you can. Layers are weakest between each other, so avoid loading a part in the direction that pulls layers apart.
4. Click Slice Plate (or Slice All for several plates), then read the preview. The preview shows material use, the colour scheme and the estimated print time.
5. Send it. Click Print, then choose Upload or Upload and Print. A pre-processing window lets you pick the printer, edit the filament mapping and set preferences before you press Send. Or choose Export G-code File and carry the file to the printer on a storage device.

Older printers: Artisan, J1/J1s and 2.0

1. Update the printer’s firmware first. Snapmaker’s wiki names V2.8.0 for the Artisan and J1/J1s and V1.21.0 for the 2.0, the versions that talk to the slicer directly without Luban.
2. Open the connection window and choose Octo/Klipper as the host type. In the host field enter the printer’s IP address followed by :8080 and click Test.
3. Click Print, then Upload and Print. Or export the G-code to a USB flash drive, put it in the machine and start the job from the touchscreen.

Settings and Materials Worth Knowing

Start with the profile Snapmaker supplies and change one setting at a time. These are general starting points, not Snapmaker specifications; your printer and filament maker’s advice comes first.

Snapmaker Orca vs Orca Slicer, ElegooSlicer, Creality Print and QIDI Studio

These programs are close relatives, so the right choice depends on your printer more than on any single feature.

Snapmaker Orca, ElegooSlicer and Creality Print are all vendor forks of Orca Slicer: each adds its maker’s printers and device features on top of the same engine. If you only own Snapmaker printers, start with Snapmaker Orca; if you own printers from several makers, Orca Slicer is the natural all-rounder. Our guides to Bambu Studio and PrusaSlicer cover the relatives further up the family tree.
