---

Bambu Studio is a feature-rich slicing software. It offers project-based workflows, systematically optimized slicing algorithms, and an easy-to-use graphic interface, delivering a smooth printing experience.

This fork tracks BambuLab's upstream and adds what desktop and Linux users miss most: native package distribution across every major platform, automated nightly and release builds, and hardened, fully reproducible CI/CD pipelines. Prebuilt Windows, macOS and Linux binaries are published on the releases page.

✨ What this fork adds

Area	Details
Native packaging	Signed APT repository, Ubuntu PPA, AUR, Fedora COPR, Flatpak, AppImage, Homebrew cask, and Windows winget
Automated releases	Nightly pre-releases from develop, GPG-signed release tags, automatic deployment to every package channel
Hardened pipelines	Pinned action SHAs, egress-audited runners, reproducible distro build containers mirrored to GHCR
Continuous security	CodeQL (security & quality), OpenSSF Scorecard, dependency review, signed commits required on master
Quality gates	A single aggregating status check guards master; every change lands through develop and a full-platform nightly first

Debian / Ubuntu — APT (recommended)

curl -fsSL https://apt.s3-dev.ovh/KEY.gpg | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/bambustudio.gpg
echo "deb [signed-by=/etc/apt/trusted.gpg.d/bambustudio.gpg] https://apt.s3-dev.ovh stable main" | sudo tee /etc/apt/sources.list.d/bambustudio.list
sudo apt update && sudo apt install bambu-studio

Supports Debian 12+, Ubuntu 22.04 and 24.04. Update with sudo apt upgrade.

Ubuntu — PPA (Launchpad)

sudo add-apt-repository ppa:benlue/bambu-studio
sudo apt update && sudo apt install bambu-studio

Native apt updates from Canonical's Launchpad. Built for Ubuntu 22.04 (jammy) and 24.04 (noble). Update with sudo apt upgrade.

Fedora — COPR

sudo dnf copr enable benlue/bambu-studio
sudo dnf install bambu-studio

Native dnf updates from Fedora COPR. Update with sudo dnf upgrade.

Arch Linux — AUR

yay -S bambu-studio-bin

Works with any AUR helper (paru, trizen, …). The pre-built binary requires no compilation.

macOS — Homebrew

brew tap BenJule/homebrew-tap
brew install --cask bambu-studio

Supports macOS 13+ (Intel & Apple Silicon). Update with brew upgrade --cask bambu-studio.

Windows — winget

winget install BenJule.BambuStudio

Requires Windows 10 or later. The .exe installer (x64 / ARM64) is also on the releases page.

Any Linux — AppImage / Flatpak

Download the portable AppImage from the releases page:

chmod +x BambuStudio_*.AppImage && ./BambuStudio_*.AppImage

A Flatpak build is also available for all distributions.

🚀 Features

Core

• Project-based workflow with GCode viewer
• Multiple plate management
• Remote control & monitoring
• Auto-arrange and auto-orient objects
• Normal / Tree / Hybrid and customized supports
• Multi-material printing with rich painting tools
• Global / object / part-level slicing parameters

Advanced

• Dynamic cooling logic controlling fan speed and print speed
• Auto brim based on mechanical analysis
• Arc path support (G2/G3) and STEP format
• Assembly & explosion view
• Flushing transition-filament into infill/object during filament change

🔧 Building from source

Supported build platforms (see the upstream compile guides):

• Windows 64-bit — Compile Guide
• macOS 64-bit — Compile Guide
• Linux — Compile Guide

On Linux, the distro packaging jobs build inside reproducible containers (Debian, Fedora, Arch) so a local ./BuildLinux.sh -dsi reproduces CI exactly.

🔄 Release process

Changes flow through a controlled, automated pipeline:

fix/feat branch ──PR──▶ develop ──nightly (all platforms)──▶ master ──tag──▶ release

• Every PR targets develop and must pass the aggregating status check.
• The nightly builds develop on all platforms (Windows, macOS Intel/ARM, Linux) and publishes a pre-release with a 14-day rolling history.
• A green, stable develop is promoted to master — the release-ready snapshot.
• Tagged releases are GPG-signed and deployed to APT, AUR, Homebrew, winget and Flatpak automatically.

🔒 Security

• CodeQL static analysis (security & quality suite) on every change to master
• OpenSSF Scorecard and dependency review on every pull request
• GPG-signed commits and release tags; force-push and branch deletion blocked on master
• Action versions pinned by commit SHA; runners restricted with egress auditing

Found a vulnerability? Please follow the security policy — do not open a public issue.

🤝 Contributing

Contributions are welcome. Every change follows Issue → Branch → PR → Review → Merge, opened against develop:

1. Open an issue describing the bug or feature.
2. Branch off develop as fix/short-description or feat/short-description.
3. Open a pull request to develop referencing the issue (Closes #N); CI runs automatically.
4. Once the status check is green, the change is squash-merged.

Report bugs and request features via the issue tracker.
