Thaum nws los txog rau 3D luam ntawv, muaj ntau yam thev naus laus zis muaj, txhua tus muaj nws tus kheej tshwj xeeb thiab kev siv. Ob txoj kev nrov yog SLA (stereolithography) thiab SLM (xaiv laser melting) 3D luam ntawv. Thaum ob txoj kev siv los tsim cov khoom peb sab, lawv txawv ntawm lawv cov txheej txheem thiab cov khoom siv. Kev nkag siab qhov txawv ntawm SLA thiab SLM 3D luam ntawv tuaj yeem pab cov neeg siv xaiv txoj kev tsim nyog tshaj plaws rau lawv cov kev xav tau tshwj xeeb.

SLM 3D luam ntawvtseem hu ua hlau 3D luam ntawv, yog ib txheej txheem uas muaj kev siv lub siab-powered laser los xaiv yaj thiab fuse metallic hmoov ua ke, txheej los ntawm txheej, los tsim ib tug khoom khoom. Txoj kev no yog qhov tshwj xeeb zoo rau kev tsim cov hlau tsis sib xws nrog cov geometry intricate, ua rau nws muaj kev xaiv nrov hauv kev lag luam xws li aerospace, automotive, thiab kev kho mob.

Ntawm qhov tod tes,SLA 3D luam ntawvsiv lub UV laser los kho cov kua resin, solidifying nws txheej los ntawm txheej los tsim cov khoom xav tau. Cov qauv no feem ntau yog siv los tsim cov qauv tsim, cov qauv sib txawv, thiab cov khoom me me hauv ntau qhov kev lag luam.

Ib qho ntawm qhov sib txawv tseem ceeb ntawm SLA thiab SLM 3D luam ntawv yog nyob rau hauv cov ntaub ntawv uas lawv siv. Thaum SLA feem ntau siv cov duab-polymer resins, SLM yog tsim tshwj xeeb rau cov hmoov hlau xws li txhuas, titanium, thiab stainless hlau. Qhov kev sib txawv no ua rau SLM zoo tagnrho rau cov ntawv thov uas xav tau lub zog, ruaj khov, thiab kub tsis kam ntawm cov khoom siv hlau.

Lwm qhov sib txawv yog theem ntawm precision thiab nto tiav. SLM 3D luam ntawv muaj ntau dua precision thiab zoo dua saum npoo zoo, ua rau nws tsim nyog rau kev ua haujlwm hlau qhov chaw nrog nruj tolerances. SLA, ntawm qhov tod tes, paub txog nws lub peev xwm los tsim cov ncauj lus kom ntxaws thiab du nto, ua rau nws nyiam xaiv rau cov qauv tsim thiab qauv zoo nkauj.

Hauv cov ntsiab lus, thaum ob qho tib si SLA thiab SLM 3D luam ntawv yog cov txheej txheem tsim khoom muaj txiaj ntsig, lawv ua raws li cov kev xav tau sib txawv thiab kev siv. SLM yog txoj hauv kev mus rau kev tsim cov khoom hlau uas muaj zog nrog cov qauv tsim, thaum SLA tau txais kev pom zoo los tsim cov qauv qhia ntxaws thiab cov qauv pom zoo. Kev nkag siab txog qhov sib txawv ntawm ob lub thev naus laus zis no yog qhov tseem ceeb rau kev xaiv 3D luam ntawv uas tsim nyog tshaj plaws rau cov haujlwm tshwj xeeb thiab cov cai.
