Fashionable 3D luam ntawv thev naus laus zis Nrog kev txhim kho thev naus laus zis thiab cov cuab yeej hloov khoom dua tshiab, txhua yam khoom tuaj yeem ua 3D luam tawm. Niaj hnub no peb yuav tham txog lub teeb kho 3D luam ntawv. Lub teeb-kho 3D luam ntawv yog lub siab ceev, siab-precision 3D luam ntawv thev naus laus zis. Siv UV lasers thiab kua UV-kho tau photopolymers- "photosensitive resins" los luam qhov chaw. Lub laser beam yog tswj los luam theej duab ntawm resin nto kom solidify cov resin nto los ua ib tug scanned ib feem ntawm cross-sectional txheej zaj duab xis. Tom qab kho ib txheej, npog cov txheej txheem tshiab nrog ib txheej ntawm cov kua resin thiab txuas ntxiv scanning kom solidify thiab muab tso rau ntawm tus ntoo khaub lig-section ntawm ib feem uas tsim los ntawm yav dhau los curing. Yog li reciprocating thiab loj hlob txheej los ntawm txheej, thiaj li mus luam ib tug tiav peb-dimensional ib feem.
SLA photosensitive resin 3D luam ntawv yog tam sim no nrov tshaj plaws 3D tshuab luam ntawv rau kev lag luam, thiab nws yog dav siv nyob rau hauv ntau lub teb xws li prototypes, prototypes, kho mob, thiab kos duab. Cov khoom tsim los ntawm 3D luam ntawv muaj qhov du, siab precision thiab zoo heev cov nyhuv. Cia peb saib cov qauv luam tawm los ntawm peb Zhongrui Technology! Loj-loj Suav zaj, complex thiab high-precision aerospace cav, mini ntxim hlub cartoon daim duab, tswv yim tsim rau kev lag luam zaub, thiab lwm yam.
Lub teeb curing khoom
Ib tiam ntawm cov khoom siv, ib tiam ntawm cov khoom siv, qhov zoo thiab qhov tseeb ntawm cov khoom ua los ntawm cov khoom sib txawv yog txawv, thiab lawv cov kev siv kuj txawv. Cov khoom siv rau lub teeb-kho 3D luam ntawv yog cov khoom siv photosensitive polymer, uas yog hais txog ib hom kev ua haujlwm ntawm cov khoom siv polymer uas tuaj yeem tsim cov tshuaj thiab lub cev hloov pauv hauv lossis nruab nrab ntawm cov molecules tom qab nqus lub zog. Nyob rau hauv lub irradiation ntawm ib tug tej yam wavelength ntawm ultraviolet lub teeb (250 ~ 300 nm), cov tshuaj tiv thaiv polymerization tshwm sim tam sim ntawd, thiab kho tiav. Nws yog ib qho tshwj xeeb cob nrog ntau yam zoo. Nws yog tsim los ntawm lub hauv paus ntawm UV txheej txheej. Tom qab kho, nws muaj cov khoom ntawm engineering plastics. Yog li ntawd, nws cov khoom yog txawv ntawm cov photosensitive resins. Feem ntau, nws yuav tsum ua tau raws li cov cai hauv qab no:
Ua ntej. Khoom siv tau zoo
1. Ceev curing ceev, me me curing shrinkage
2. High degree ntawm kev kho ib zaug
3. Tsawg viscosity
4. Cov khoom kho tau zoo txhua yam khoom
5. Cov khoom kho tau swells me ntsis
6. Zoo hnyav kuj
7. Tsim nyog qhov sib kis qhov tob
8. Zoo cia ruaj khov
9. Tsawg toxicity
Thib ob, Kev faib cov khoom siv
Raws li cov tshuaj tiv thaiv mechanism ntawm lub teeb-kho resin koom rau hauv lub teeb-kho crosslinking txheej txheem, lub teeb-kho resin yuav muab faib ua:
(1) Radical light-curable resin (qhov no yog thawj hom khoom peb siv)
(2) Cationic light-curing resin (tus nqi siab, kev ua haujlwm zoo)
(3) Hybrid light-curing resin (Cov qauv yav tom ntej)
