  1. Stable

    OrcaSlicer 2.4.2

    This is the OrcaSlicer V2.4.2 release — a maintenance update on top of 2.4.1, focused on making profiles, cloud sync, and printer connectivity more dependable. Upgrading from an older version is smoother: presets that were built on a printer or filament that…

  2. Stable

    OrcaSlicer 2.4.1

    This is the OrcaSlicer V2.4.1 release — a maintenance update on top of 2.4.0 with a broad round of profile and preset fixes at its core: it restores filaments that had gone missing or were miscategorized in the Orca Filament Library and the filament selection…

  4. Pre-release

    OrcaSlicer 2.4.0-beta

    This is the OrcaSlicer V2.4.0 Beta. A lot of effort has gone into this release to improve stability, speed, and print quality, along with the interface and printer support. Bridging in particular has been greatly improved by @ianalexis, @kisslorand, and many…

Source review:

Good to know

OrcaSlicer is an open-source FFF slicer with detailed calibration tools, broad printer support and direct connections to several network print hosts. It combines a modern plate workflow with unusually deep control over extrusion, walls, seams and motion.

Sources reviewed:

Where it fits

A strong choice when you tune a Klipper, Bambu, Prusa, Voron or other FFF machine and want calibration, slicing and network delivery in one application.

Install and update note

Use the stable release for routine printing; nightlies are for testing recent changes. Match the package to the CPU and operating system, and export important presets before a major upgrade.

Common questions

Where is the official OrcaSlicer download?

The project identifies orcaslicer.com and the OrcaSlicer GitHub repository as its official channels. The repository explicitly warns about look-alike download sites, so verify the domain before installing.

Check the source ↗
Which OrcaSlicer package should I choose?

Windows publishes installers for x64 and ARM64 plus a portable option. macOS uses a universal DMG, while Linux offers Flathub and AppImages for x86_64 and aarch64.

Check the source ↗
What makes OrcaSlicer's calibration workflow different?

Its documentation groups temperature, flow ratio, pressure advance, retraction, tolerance, volumetric speed and motion tests into a dedicated calibration workflow instead of leaving them as unrelated settings.

Check the source ↗
Can OrcaSlicer send jobs directly to networked printers?

Yes. The official feature list names integrations such as Klipper, PrusaLink and OctoPrint. Availability still depends on the selected printer profile and host configuration.

Project documentation ↗
A quick check before installing
0/3

A project file is not an installer

A .3mf file holds model or project data. Opening it does not install the slicer. After opening a project, check the printer, nozzle and material settings.

Check the official requirements

Files are hosted by the developers. Before installing, check their system requirements and release notes. A file labelled for your platform does not establish the minimum OS version.
