1. Cov Ntsiab Lus Tseem Ceeb thiab Txhim Kho Pawg
1.1 Kev txhais lus thiab Core Device
(3d luam ntawv alloy hmoov)
Steel 3D luam ntawv, zoo li no hu ua hlau additive manufacturing (AM), yog ib txheej txheej txheej txheej txheej tsim tsim uas tsim peb-dimensional metallic Cheebtsam ncaj qha los ntawm digital versions siv cov hmoov los yog hlau feedstock.
Tsis zoo li kev rho tawm xws li milling lossis tig, uas tshem tawm cov khoom kom tau txais daim ntawv, steel AM ntxiv cov khoom raws li qhov xav tau, enabling extraordinary geometric complexity nrog me me pov tseg.
Cov txheej txheem pib nrog 3D CAD version hlais rau hauv nyias cov khaubncaws sab nraud povtseg (feem ntau 20– 100 µm tuab). Ib qhov chaw muaj zog heev– laser lossis electron beam– precisely melts los yog fuses steel fragments raws li ib tug txheej ntawm cross-section, uas solidifies thaum txias los ua ib tug tuab tuab.
Lub voj voog no rov ua dua kom txog thaum cov khoom ua tiav tiav, feem ntau nyob rau hauv ib qho inert ambience (argon los yog nitrogen) to prevent oxidation of responsive alloys like titanium or light weight aluminum.
The resulting microstructure, mechanical residential or commercial properties, and surface coating are regulated by thermal background, check approach, and material characteristics, requiring precise control of procedure specifications.
1.2 Significant Metal AM Technologies
Both dominant powder-bed fusion (PBF) modern technologies are Discerning Laser Melting (SLM) and Electron Beam Of Light Melting (EBM).
SLM uses a high-power fiber laser (commonly 200– 1000 W) to fully melt metal powder in an argon-filled chamber, producing near-full density (> 99.5%) parts with fine function resolution and smooth surface areas.
EBM utilizes a high-voltage electron beam in a vacuum cleaner environment, running at higher construct temperature levels (600– 1000 ° C), uas txo qis kev ntxhov siab nyob hauv thiab tso cai rau kev ua haujlwm tawg-tiv taus ntawm nkig alloys zoo li Ti-6Al-4V lossis Inconel 718.
Tom qab PBF, Directed Energy Deposition (DED)– muaj xws li Laser Hlau Deposition (LMD) thiab Cord Arc Ingredient Manufacturing (WAAM)– pub hlau hmoov los yog cable rau hauv lub pas dej ua luam dej uas tsim los ntawm laser, ntshav ntshav, los yog hluav taws xob arc, haum rau loj-scale fixings los yog ze-net-puab qhov chaw.
Binder Jetting, txawm li cas los xij tsis tshua muaj cog rau cov hlau, Nws suav nrog kev hloov cov kua dej sib txuas mus rau cov hlau hmoov txheej, ua raws li sintering nyob rau hauv ib tug cua sov system; nws siv kev kub ceev tsis tau qis dua thiab qhov tseeb qhov tseeb.
