TrioSlicer

Android slicer for 3D printing - CuraEngine, OrcaSlicer, PrusaSlicer engines and Ai driven blender.

TrioSlicer (formerly DuoSlicer, and EnderSlicerCura before that) is an Android-first front end for CuraEngine, PrusaSlicer and OrcaSlicer - importing, preparing, slicing, previewing and sending 3D prints from a phone or foldable. It is 1.4.0 and runs on Android 10+ on ARM64, with all three engines cross-compiled for the phone together with their own upstream profile systems: CuraEngine 5.14.0-alpha.0, PrusaSlicer 3.0.0-alpha11 and OrcaSlicer 2.4.2. Its most-tested baseline is a modified Creality Ender 3 V2.

What it does Slices on the phone, offline. Three engines behind one switcher, each with its own settings and profile tree, and an accent colour that follows the active one: Cura (blue), PrusaSlicer (orange), OrcaSlicer (teal). Saved profiles belong to one engine. Print profiles and filaments are captured from, listed for and applied to the active engine, each behind its own type-and-range check, so the Profiles & filament sheet can only ever change the settings the running engine reads. Takes the setup you already have. Cura .3mf projects and .curaprofile files, PrusaSlicer .ini config bundles, OrcaSlicer presets and bundles, and STL models. Plate, viewer and preview. Move, rotate, scale, centre, lay flat and drop to bed; build-volume checks before slicing; OpenGL viewer; layer preview; nozzle-path view with speed-coloured beads. Edits a sliced print without re-slicing. Pause, filament change, temperature, fan, speed, flow, retraction, camera, message and guarded custom G-code, placed as layer events. Automatic mesh leveling (AML) for mriscoc firmware: the probe sequence covers the model footprint instead of the whole bed, so leveling takes seconds. BumpMesh texturing, offline. Planar, triplanar, cubic or cylindrical displacement mapping, 100k-8M triangles. Modelling with Blender 3.6 inside the app. An AI agent drives the embedded engine over a local MCP socket, sees the same render you do, and hands the finished STL to the plate. An AI assistant on the plate. It talks to a DeepSeek harness you run yourself: ask about the model, paint a region to show what should change, or have a photograph turned into a printable STL on a remote GPU box. Smart Infill and build-process thermal FEA (filaSim), solved natively on the phone, offline. Experimental overhang paths - arc (Multiplex), wave and the smart overhang strategy, mutually exclusive and off by default. OctoPrint: encrypted authorization, upload, select, print, file browser, monitoring, webcam and guarded printer controls.
