How to Use Orca Slicer

Step 1: Launch Orca Slicer

Once you’ve installed the software. Open Orca Slicer on your computer. You can see a clean and organized dashboard. It shows you options to add a printer, load models, and start slicing.  Select your printer model type of filament.

Step 2: Add Your 3D Printer

Before slicing any model. You need to add your printer profile.

• Click on “Add Printer” from the top menu.
• Choose your printer brand and model. Choose from the list.
• If your printer isn’t listed. You can manually create a custom printer profile by entering parameters. Add the bed size, diameter, and filament.

Step 3: Import Your 3D Model

Now import and load your 3D model file.

• Click on “Open File” or simply drag and drop your.STL or.OBJ file into the Orca Slicer.
• The model will appear in the 3D preview.
• You can move, rotate, or scale it using toolbar.

Step 4: Adjust Print Settings

When your model is loaded. You can customize your print settings:

Layer Height

Controls print quality. Select smaller layers = smoother print.

Infill Density

Adjust how solid your model is for standard prints.

Supports

Add automatic support for models with overhangs.

Adhesion

 Enable a skirt or raft if needed for bed adhesion.

Step 5: Choose Filament and Material

Orca Slicer enable to select the type of filament. Choose the option from  PLA, ABS, and TPU.
You can pick from the Global Filament Library. Create your own custom filament profile.
Each material provides recommended temperature and speed settings.

Step 6: Preview Your Print

Before slicing, use the Preview Mode to inspect your print situation.

• Click on “Preview” to see how each layer printed results.
• Check supports, infill patterns, and travel paths.
• You can adjust settings if something doesn’t look right.

Step 7: Slice Your Model

When everything looks good, click “Slice”. It processes your model and generates the G-code file for your printer. You can see estimated print time, material usage, and cost. 

Step 8: Send to Printer or Save the File

Once slicing is done, you can choose from two options:

• Save the G-code file in SD card or USB.
• Send it to your printer over Wi-Fi and using the Device Tab.  

Step 9: Monitor Your Print 

If you’re using the Obico integration. You can monitor your print remotely:

• Watch a live webcam feed.
• Get AI-based alerts for print failures.
• Pause or stop prints from anywhere.

Step 10: Fine Tuning

After printing, you can review your results and changing adjustments:

• If the print shows stringing or blobs. Try lowering retraction or temperature.
• If layers don’t stick well. Increase bed temperature or add a raft.
• Save your optimized settings as a custom profile for future prints.
