Download Now (v2.3.2)What is Orca Slicer?
Orca Slicer is an open-source 3D printing software that converts 3D models into G-code, which is the exact language your printer understands. It slices your model into thin layers and tells the printer how to move, when to extrude material, and how fast to print. In short, it translates your imagination into physical form.
SoftFever developed Orca Slicer using Bambu Studio as a starting point, then made it more flexible and packed with features. It’s a community-driven upgrade that takes the best parts of Bambu Studio, SuperSlicer, and PrusaSlicer, and adds its own smart improvements.
Orca Slicer runs well on Windows, macOS, and Linux, and includes printer profiles that are ready to use. You can start printing quickly without spending a lot of time adjusting settings.
Features in Detail
1. Advanced Algorithm
Orca’s slicing engine is built to handle even the most complex models without slowing down. It calculates precise tool paths and optimizes the print speed and layer thickness to reduce time and material waste. You can expect faster prints with clean, detailed results.
2. Precise Wall and Seam Control
If you’ve noticed small ridges or uneven walls on your prints, you know how annoying that can be. Orca Slicer helps by letting you control where seams appear. You can hide them, line them up, or place them randomly, depending on your model. The precise wall feature gives you smoother surfaces and stronger edges.
3. Calibration Tools
Getting great prints depends on good calibration, and Orca Slicer has all the tools you need. You can adjust temperature, flow rate, retraction, and pressure advance with easy-to-follow tests.
- Temperature test for consistent filament flow
- Flow rate tuning to avoid over or under extrusion
- Retraction tests to reduce stringing
- Pressure advance calibration to eliminate blobs and oozing
- Tolerance tests for perfect fitting parts
- Vertical Fine Artifact tests for the cleanest surface finish
4. Wide Compatibility
A major advantage of Orca Slicer is that it works with many different printers. It supports brands like Prusa, Bambu Lab, and more. You can also use it with custom or DIY printers because of its flexible profiles.
5. Regular Community Updates
Since it’s open-source, anyone can contribute to Orca Slicer. Developers, makers, and everyday users help improve the software by adding features, fixing bugs, and optimizing performance. The result is a tool that keeps getting better with every update.
6. Open-Source Advantage
Because Orca Slicer is open-source, you’re free to customize it to fit your workflow. Whether you want to modify settings, integrate scripts, or explore advanced slicing logic, the flexibility is in your hands.
What’s New in the Latest Version
The latest version of Orca Slicer is much easier to use. One standout feature is its integration with Obico, which lets you manage your 3D printer from anywhere.
Here’s what you can now do right from inside Orca Slicer:
- Control your printer remotely. Start or stop prints even when you are away.
- Monitor in real-time. Watch live video feeds and track progress on your phone or computer.
- AI failure detection. Two smart systems now analyze your print and the first layer to detect problems before they ruin the entire job.
- Notifications and alerts. If your print fails, the system can pause or stop automatically.
- Direct integration with OctoPrint, Mainsail, and Fluidd. Send files wirelessly and manage everything from one dashboard.
These updates make Orca Slicer more than just slicing software. It becomes your printing assistant, keeping your workflow organized and efficient.

Steps to Install
- For Windows: Run the
.exefile, follow the on-screen setup, and finish installation. - For macOS: Open the
.dmgfile and drag the Orca Slicer icon to your Applications folder. - For Linux: Run the
.AppImagefile directly or execute it using the terminal.
Once installed, open Orca Slicer. The first time you run it, a setup wizard will guide you through adding your printer and filament profiles. That’s it you are ready to slice your first model.
It’s easy to get started with Orca Slicer. You can go from opening the app to printing your first object in just a few steps.
How to Use Orca Slicer
Using Orca Slicer is simple once you know the basics. It’s designed to make 3D printing faster, easier, and more precise. Follow these quick steps to get started.
1. Set Up Your Printer
When you open Orca Slicer for the first time, it asks you to select your printer.
- Choose your printer model from the list, or add a custom one if it’s not listed.
- Pick your filament type such as PLA, PETG, or ABS. Orca automatically adjusts print temperature and speed for your chosen material.
- If your printer supports Wi-Fi (like Bambu Lab models), you can connect directly and send files wirelessly.
2. Import Your 3D Model
Click New Project, then drag and drop your 3D model file (STL, OBJ, or 3MF) into the workspace.
You can move, rotate, or resize your model using the tools on the left. Make sure it’s placed flat on the virtual bed for better adhesion.
3. Adjust Print Settings
Orca Slicer offers ready-made profiles, but you can customize settings if you want.
- Layer Height: Thinner layers give more detail.
- Infill Density: Higher infill means stronger prints.
- Supports: Add supports only where needed to save material.
- Print Speed: Slower speeds improve surface quality.
4. Slice and Preview
Click Slice Plate to generate the G-code. Then use the Preview Mode to check each layer and confirm there are no gaps or floating parts. This helps prevent print failures before you start.
5. Send the File to Your Printer
You can export the sliced file in several ways:
- Save to an SD card or USB and insert it into your printer.
- Send directly via Wi-Fi if your printer supports it.
- Connect through OctoPrint, Klipper, or Obico to monitor prints remotely.
Once printing starts, watch the first few layers to ensure good bed adhesion. After that, Orca Slicer handles the rest smoothly, giving you consistent, high-quality results every time.
