OrcaSlicer is an open-source slicer software for 3D printing that has quickly become popular. Originally created as a fork of Bambu Studio, it blends modern user interface design with advanced control over the slicing process.
The source code can be found in the OrcaSlicer github repository.

Key Features
Built-in Calibration Tools
OrcaSlicer includes built-in test suites for temperature, pressure advance, flow rate, max volumetric speed, and retraction tuning directly within the application, eliminating the need for manual G-code tweaks.
Broad Machine Support
Unlike slicers tied strictly to single ecosystems, OrcaSlicer natively supports a wide variety of 3D printers, including Voron, Creality, Anycubic, Elegoo, Prusa, and Bambu Lab machines. Bambu Lab are a bit special though as they only directly connect to OrcaSlicer when in Lan only mode and requiring Bambu Connect to act as a middle man otherwise.
Advanced Features
It packs power-user capabilities such as native Klipper integration, organic tree supports, per-plate settings for multi-object prints, and precise seam placements. More or less all the new features are part of OrcaSlicer or are being added shortly after.
Modern Interface
Its tab-based design provides a clean preview mode and straightforward project organization without sacrificing access to deep technical parameters.
