nx_print_process.nx

nx_print_process.nx -- bits-up sealed enum of additive-manufacturing PROCESS classes (orthogonal to material chemistry; classifies the physics of how the material is deposited and consolidated). ===================================================================== Multi-process / multi-material vision ===================================================================== Operator directive (2026-05-20): "i want to print lots of materials like concrete metal glass clay etc as you roadmap out so i could hypothetically have different types of printers printing different parts on a timing that lets a robot put them together" This file is the BITS-UP foundation for that vision. Every process class below has measurably different physics (temperature, viscosity, cure mechanism, layer time, mechanical strength). The NxMaterialProfile struct currently models FDM polymers; future profile shapes (sealed per-process structs) will model: - DIW dispensing rate + cure-vs-print-rate ratio (concrete, clay) - SLA cure energy + wavelength + Z-jerk-at-peel - DMLS laser power + scan speed + powder bed parameters - Binder jet droplet volume + saturation + cure cycle Substrate primitives queued (NOT in this file yet): nx_print_backend -- per-process emit interface (extends NxGcodeEmitter) nx_build_plan -- multi-part coordination (which printer, which part, when) nx_assembly_timing -- per-part complete-by-T, robot-pickup-at-T schedule nx_robot_pickup_spec -- end-effector orientation, grip force, part registration nx_part_compatibility -- interlock + fit verification across separately-printed pieces nx_coord_frame_transform -- bed coords -> assembly coords per part EXCEED motivation: NO production slicer handles cross-process coordination. OrcaSlicer / Bambu / Cura / PrusaSlicer are FDM-only. Specialized slicers exist per-process (Chitubox for resin, Materialise Magics for DMLS, etc.) but none coordinate ACROSS process types with timing for assembly. Nishi's bits-up substrate model treats process as a sealed enum parameter to a unified slicer + emitter stack, so a single .nx conductor can schedule: "FDM PLA torso prints on printer A by T+4h, concrete base
