1// nx_print_process.nx -- bits-up sealed enum of additive-manufacturing 2// PROCESS classes (orthogonal to material chemistry; classifies the 3// physics of how the material is deposited and consolidated). 4// 5// ===================================================================== 6// Multi-process / multi-material vision 7// ===================================================================== 8// 9// Operator directive (2026-05-20): 10// "i want to print lots of materials like concrete metal glass clay 11// etc as you roadmap out so i could hypothetically have different 12// types of printers printing different parts on a timing that lets 13// a robot put them together" 14// 15// This file is the BITS-UP foundation for that vision. Every process 16// class below has measurably different physics (temperature, viscosity, 17// cure mechanism, layer time, mechanical strength). The NxMaterialProfile 18// struct currently models FDM polymers; future profile shapes (sealed 19// per-process structs) will model: 20// - DIW dispensing rate + cure-vs-print-rate ratio (concrete, clay) 21// - SLA cure energy + wavelength + Z-jerk-at-peel 22// - DMLS laser power + scan speed + powder bed parameters 23// - Binder jet droplet volume + saturation + cure cycle 24// 25// Substrate primitives queued (NOT in this file yet): 26// nx_print_backend -- per-process emit interface (extends NxGcodeEmitter) 27// nx_build_plan -- multi-part coordination (which printer, which part, when) 28// nx_assembly_timing -- per-part complete-by-T, robot-pickup-at-T schedule 29// nx_robot_pickup_spec -- end-effector orientation, grip force, part registration 30// nx_part_compatibility -- interlock + fit verification across separately-printed pieces 31// nx_coord_frame_transform -- bed coords -> assembly coords per part 32// 33// EXCEED motivation: NO production slicer handles cross-process coordination. 34// OrcaSlicer / Bambu / Cura / PrusaSlicer are FDM-only. Specialized slicers 35// exist per-process (Chitubox for resin, Materialise Magics for DMLS, etc.) 36// but none coordinate ACROSS process types with timing for assembly. 37// 38// Nishi's bits-up substrate model treats process as a sealed enum parameter 39// to a unified slicer + emitter stack, so a single .nx conductor can 40// schedule: "FDM PLA torso prints on printer A by T+4h, concrete base 41// prints on printer B by T+8h, robot assembles at T+9h". 42// 43// license_tier: ORIGINAL 44 45import "nx_syscalls.nx" 46 47// ===== sealed enum: print process classes ========================= 48 49const NX_PROCESS_FDM_POLYMER: i64 = 0 // current substrate (PLA/PETG/etc) 50const NX_PROCESS_DIW_CEMENT: i64 = 1 // direct ink writing -- concrete, mortar 51const NX_PROCESS_DIW_CLAY: i64 = 2 // DIW -- ceramic green body, dry+kiln after 52const NX_PROCESS_DIW_BIOPRINT: i64 = 3 // DIW -- hydrogel / bio-ink (tissue scaffolds) 53const NX_PROCESS_SLA_RESIN: i64 = 4 // vat photopolymerization, UV cure 54const NX_PROCESS_DMLS_METAL: i64 = 5 // direct metal laser sintering, powder bed 55const NX_PROCESS_EBM_METAL: i64 = 6 // electron beam melting, vacuum chamber 56const NX_PROCESS_BINDER_JET: i64 = 7 // powder + binder droplets, post-cure 57const NX_PROCESS_FDM_METAL: i64 = 8 // metal-filled FDM (BASF Ultrafuse 316L, etc.) 58const NX_PROCESS_FDM_GLASS: i64 = 9 // soda-lime or borosilicate via FDM 59const NX_PROCESS_LDM_FOOD: i64 = 10 // liquid deposition modeling for chocolate/etc 60const NX_PROCESS_SLM_METAL: i64 = 11 // selective laser melting (cousin of DMLS) 61const NX_PROCESS_FFF_WOOD: i64 = 12 // wood-filled FDM 62const NX_PROCESS_N: i64 = 13 // count 63 64func nx_process_is_valid(p: i64) -> i64 { 65 if p < 0 { return 0 } 66 if p >= NX_PROCESS_N { return 0 } 67 return 1 68} 69 70// ===== process taxonomy queries =================================== 71// 72// Each predicate is O(1) so callers can dispatch on physics without 73// switch-casing.
