Bambu Studio Basics

Bambu Studio is the free slicer software for Bambu Lab printers. It takes 3D model files (STL, 3MF, OBJ) and converts them into print instructions (G-code) that the printer understands. It's based on PrusaSlicer but with deep integration with Bambu hardware: automatic calibration profiles, direct cloud printing, and MakerWorld integration.

1. Download from the Bambu Lab website (bambulab.com/download)
2. Install and launch
3. Log in with your Bambu Lab account
4. Select your printer model in the setup wizard, then bind the printer: in Bambu Handy (Devices → + Bind Printer) or in Studio via PIN code (A, P and H series; the X1 series does not support it) or IP address plus LAN access code. It then shows up on the Device tab.

• 3D view (center): Your build plate. Drag models here, move them, arrange them.
• Left sidebar: Printer, Filament and Process presets, with the object list below
• Toolbar above the 3D view: Import, Move (M), Rotate (R), Scale (S), Place on Face (F) and the other tools
• Top bar: View modes, slice button, send to printer
• Device tab: Printer status, camera view and remote control

1. Import: Drag and drop an STL file onto the build plate, or use File → Import
2. Position: Select the model. Use Move (M), Rotate (R), Scale (S), Place on Face (F)
3. Configure: In the left sidebar, verify Printer, select Filament, set Process (layer height)
4. Slice: Click "Slice Plate", check estimated time, filament use, and layer preview
5. Send: Click "Print" to send over Wi-Fi, or export to the microSD card or USB drive (depending on the model)

Enable in Process → Support. Which surfaces get support depends on the threshold angle: with an auto support type, Bambu Studio supports every surface whose slope to the horizontal is less than the threshold. The default is 30°, which Bambu calls safe to print without support for most materials. A higher threshold generates more support.

• Normal supports: project the overhang straight down to the plate. Under large flat overhangs they usually give a better underside than tree supports.
• Tree supports: grow branches down from points on the overhang. For complex models with mostly small, curved overhangs they are stronger and use less material and time, at similar surface quality.
• Tree Hybrid: normal grid support under big flat overhangs, tree support everywhere else. Studio picks this style by default when you print with support filament or adaptive layer height; otherwise the default is Tree Organic.

Top Z distance: when model and support use the same filament, keep it around 0.2 mm. Set it to 0 only with a dedicated support filament such as Bambu Support for PLA, or the support becomes very hard to remove.

Every support setting, support filaments, PVA and fixes in one place: Supports in Bambu Studio.

• 2 walls, visual/display models
• 3–4 walls, functional parts
• 4+ walls, structural / high-load parts

More walls = stronger part, longer print time. Walls matter more than infill for strength in most cases.

Bambu Studio supports multiple plates in one project file. Add a new plate with the Add Plate button in the toolbar (up to 36 per project) and drag models to it; each plate can have its own settings. Slice all / Print all works on the H2 series, X1 series and P2S, on the P1S with a "Send All Plates" prompt, and not yet on the A series. Useful for batching prints with different materials or settings in one session.

For cloud printing, the file uploads to Bambu's servers and the printer pulls it. For LAN-only mode (useful if you've disabled cloud access), your computer has to reach the printer over your local network; if the two sit on different subnets or VLANs, bind the printer with its IP address plus access code. LAN mode is also faster for large files.
