OrcaSlicer Mobile v0.1.0 (alpha)

First public release of OrcaSlicer Mobile — an Android slicer running the real OrcaSlicer (libslic3r) engine on-device.

Highlights

• Full OrcaSlicer slicing engine (Arachne walls, tree supports, seam control, and more)
• Import OrcaSlicer .orca_printer / .orca_filament profile bundles, with inheritance resolution and the full extruder/retraction block now preserved
• Multi-color painting with brush, bucket-fill, and height-range tools (up to 16 filaments), with proper tool changes, prime tower, and per-filament flush volumes in the sliced G-code
• Cut tool with plane preview, round/square brush shapes
• G-code preview with feature and filament/tool color views
• Fully offline — no account, no cloud

Fixes in this release

• Flush volume matrix is now sized to the painted filament count (fixes "Flush volumes matrix do not match to the correct size" with any color count other than 4)
• Painted colors now apply to vertical walls, not just top/bottom surfaces (fixed a static-initialization-order bug in the engine's paint segmentation that silently discarded all wall paint on Android builds)

Install

Download the APK below and sideload it. Requires Android 5.0+ on a 64-bit ARM device (arm64-v8a).

⚠️ Alpha software, debug-signed build. Always sanity-check sliced G-code in the preview before printing.
