A self-hosted slicer for your server. Trident runs OrcaSlicer's slicing engine headless in Docker, with a web UI you can use from any browser or phone. It works with the printers OrcaSlicer supports, resin printers, and belt (conveyor) printers as a bonus. (Trident Studio is the app's name; the image and repository are still trident.)
Security: in single-user mode there is no login, so anyone who can reach port 8000 can use Trident. Keep it on your home network, or use multi-user mode behind an HTTPS reverse proxy.
FDM slicing with OrcaSlicer's full printer, filament and process library (70+ vendors, 800+ settings), plus import of your own profiles, and your own printers and materials
Multi-material and tool-changer printers (for example the Snapmaker U1), multi-plate 3MF files with object picking
Position, scale, auto-orient, auto-arrange and copies; layer-by-layer G-code preview, including Bambu G-code
Resin (MSLA) printing: 150+ printers, a library of published resin exposure and lift settings, supports, hollowing, a layer preview with a peel warning and cost, and your own printers and resins. The formats have not been checked on real printers yet: please report what works
A Printers page: your saved Klipper (Moonraker) and Bambu printers with state, progress, temperatures and camera, and Pause, Resume and Cancel
Send G-code to printers: Moonraker (Klipper) and OctoPrint, and Bambu Lab printers: in Developer Mode (LAN), or sent to the printer's storage in ordinary cloud mode. An experimental mode can start a print on a Bambu printer that is not in Developer Mode (off unless you turn it on; tried on an A1 mini only)
Works with Holecraft, a self-hosted 3D modeler: it sends designs here with an API key, and uses Trident for resin hollowing and support points
Belt printer support (IdeaFormer IR3 V2 and similar)
