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.

Main Features

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.

installation guide

If you are facing issues check orca Issues and solutions and compile process If you have trouble running it, use the command: chmod +x /path_to_appimage/OrcaSlicer_Linux.AppImage.

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

The Mega and Kobra series from Anycubic provide affordable options with decent build quality. Many hobbyists prefer them for everyday 3D printing.

Artillery

Artillery printers, such as the Sidewinder and Genius, are known for quiet operation and large print volumes. They are user-friendly and great for bigger projects.

Custom setups allow more flexibility with features like dual extruders (IDEX) or multiple tools. They work well for specialized printing needs. You can also explore slicers like PrusaSlicer and Cura for better results.

How to Import 3D Models in OrcaSlicer

Before slicing, you need a model. Here are three simple ways to import it:

  1. Click the Cube Icon
    Use the cube icon in the top toolbar to browse and import your 3D file.
  2. Drag and Drop
    Simply drag your file from your computer onto the build plate.
  3. Use the File Menu
    Go to File → Import, select your file type, then choose your model
