Understanding the Interface
When you first open OrcaSlicer, you're greeted with a clean 3D viewport and a toolbar on the left. The main areas you'll interact with are:
- Top toolbar: Add models, arrange objects, and slice.
- Left panel: Object list and transformation tools (move, scale, rotate).
- Right panel: Printer, filament, and process (print settings) selections.
- Bottom bar: Layer preview and slicing controls.
Spend a few minutes clicking around these panels before loading your first model — understanding where things live will save you a lot of time later.
Importing a Model
To add a 3D model to your build plate, you have three options:
- Click the Add button (cube with a plus icon) in the top toolbar.
- Drag and drop an STL, 3MF, OBJ, or STEP file directly onto the viewport.
- Use File → Import → Import 3D Model from the menu bar.
OrcaSlicer supports all common file formats. The 3MF format is particularly useful because it preserves all your slicer settings alongside the model geometry.
Selecting a Printer Profile
Before you do anything else, make sure you have the correct printer selected in the right panel. OrcaSlicer ships with profiles for many popular printers including Bambu Lab, Creality Ender series, Prusa MK series, Voron, and many more.
If your printer isn't listed, you can:
- Search for a community-created profile on GitHub or the OrcaSlicer forums.
- Create a custom profile based on a similar machine and adjust the bed size and firmware settings.
Tip: Always verify your bed dimensions and nozzle diameter match your actual hardware before slicing.
Configuring Basic Settings
Once your printer is selected, choose your filament type (PLA, PETG, ABS, etc.) from the filament dropdown. OrcaSlicer includes well-tuned generic profiles for all common materials.
For a basic first print, focus on these three settings in the Process panel:
| Setting | Recommended Starting Value | What It Does |
|---|---|---|
| Layer Height | 0.2 mm | Controls print resolution and speed |
| Infill Density | 15–20% | How solid the inside of the print is |
| Support | Auto (Normal) | Generates support structures for overhangs |
Slicing and Exporting
When your settings are configured, click the Slice button (or press Ctrl+R). OrcaSlicer will process the model and display a layer-by-layer preview. Use the layer slider on the right to inspect the toolpath for any obvious issues.
Once you're happy, export your file:
- Export G-code: For SD card or USB printing.
- Send to Printer: If your printer is connected over LAN (Bambu Lab, Klipper, etc.).
- Export 3MF: To save your project with all settings intact.
Congratulations — you've sliced your first model with OrcaSlicer! From here, explore the calibration tools and advanced settings to dial in even better print quality.
