What is Orca Slicer?
Orca converts 3D models into G code. Printers understand G code language easily. So orca helps to print better after converting 3d models. It also slices the 3D models to thin horizental layers and create path for printer nozzle. Hence you will get high quality printing, better output and more flexible projects.
Orca Slicer reduces Z-seams with Seam Gap and Wipe on Loops, ensuring smoother prints with less blobbing and precise seam control. Users will get more control over prints because of additional printers profiles. Main benefit is that orca works on higher number of printers than orher traditional slicers.
OrcaSlicer has 10.7k+ stars, 1.4k forks, and 443 contributors on Github. It has seen 67 official releases, with the latest being v2.3.0 (March 20, 2025)
Main Features of OrcaSlicer
Auto Calibration
Orca has advance calibration tools that work in auto mode as well. Some calibrations, such as the temperature tower test, flow rate calibration, retraction test, tolerance testing, and others, are included.
Polyholes Support
This feature prevents deformation caused by numerical miscalculations. It also ensures the accuracy of holes and circular shapes in 3D designs.
Klipper Support
It works with Klipper firmware. This allows users to optimize prints on their printers, enabling Klipper for fast and accurate printing.
Granular Controls
It provides more granular controls than other slicers. These controls help create desired 3D products. Users can adjust parameters such as print speed, layer heights, pressure, and temperatures.
Sandwich Mode
Sandwich mode is a feature that helps users control layer properties, such as applying different patterns at varying densities from the inside to the outside. This produces clear and unique prints.
Easy to Use
Any newbie can use Orca Slicer easily. Thanks to its intuitive interface and straightforward navigation options, it is very user-friendly. You can create print models effortlessly, whether you are an expert or a beginner.
Works with 3D Printers
One of the main reasons for the increasing downloads of Orca Slicer is its compatibility with a wide range of 3D printers. This gives Orca more flexibility compared to traditional software.
Open and Free
Orca Slicer is an open-source project. It is made by the people, for the people. There are no charges, and it is absolutely free to use.
Printer Control
Now you can control your printer’s interface from your PC or laptop. This makes it much easier to perform 3D printing tasks smoothly.

How To Compile (Build Guide)
For Windows, you need Visual Studio 2019, CMake (3.14+), Git, Git LFS, and Strawberry Perl.
To build, run:
build_release.bat
Make sure you use the x64 Native Tools Command Prompt, run git lfs pull after cloning, and confirm that the Windows SDK is installed.
On macOS, install Xcode Command Line Tools, CMake, Gettext, Libtool, and Automake.
Build using:
./build_release_macos.sh
You’ll need Xcode 11 or higher, adjust scheme settings in Xcode, and check Homebrew dependencies.
Linux builds use Docker Engine, Git, and Build Essentials.
Run the following commands:
./DockerBuild.sh
./DockerRun.sh
Verify Docker permissions, check kernel version requirements, and review the Dockerfile setup before running.
For Ubuntu/Debian, dependencies are installed automatically via the script.
Use these commands:
sudo ./BuildLinux.sh -u
./BuildLinux.sh -dsir
Run with administrator rights, verify package manager sources, and check for secure boot conflicts.
Orca Supported printers
Creality Printers
Creality is well-known for its Ender and CR series. These models are budget-friendly and a good choice for beginners who want reliable prints.
Prusa Printers
Prusa offers high-quality machines like the i3 MK3 and the larger Prusa XL. They are popular for consistent performance and strong community support.
Anycubic
