Cov kua tshuaj tshiab tshiab rau kev lag luam 3D Printing: Precision in Material Formulation

Kev txhim kho sai ntawm 3-D luam tawm lub sijhawm tau pom zoo cov khoom tsim nyog zoo dua rau kev ua haujlwm tag nrho ntawm cov dej haus tshuaj. Kev tsim cov ntaub ntawv tseeb yog qhov tseem ceeb rau kev tsim kho tshiab hauv 3-D luam ntawv ntawm cov dej haus tshuaj.

UV curable cob
Lub teeb kho tau 3-D luam ntawv era yog predicated ntawm photosensitive resins li cov ntaub ntawv luam ntawv. Daim ntawv no ntawm cov kua tshuaj hu rau tshwj xeeb manipulate ntawm nws cov viscosity, shrinkage tus nqi, hardness, thiab txawv tag nrho cov kev ua tau zoo tsis ua kom paub tseeb tias daim ntawv raug, mechanical zog, thiab pem teb zoo tshaj plaws ntawm cov ntsiab lus tshaj tawm. Los ntawm kev hloov kho tshuaj hauv chav kawm thawj zaug, cov khoom siv photocurable uas ua tau raws li qhov tshwj xeeb 3-D tshuab luam ntawv thiab kev ceeb toom yuav tsum tau tsim.
Cov khoom siv thermoplastic
Thermoplastic 3-D luam ntawv dav siv cov txheej txheem fused deposition modeling (FDM), uas ib txwm hu rau ib tug thermoplastic polymer soften vim cov tshuaj kua. Lub soften index, thermal deformation kub, crystallization kinetics, thiab cov chaw nyob sib txawv ntawm daim ntawv no ntawm daim ntaub ib zaug muaj kev cuam tshuam rau kev luam ntawv raug thiab cov khoom siv tag nrho. Kev ua kom zoo ntawm cov tshuaj ua kua tshuaj tuaj yeem pab txhim kho qhov tseeb qhov tseeb, lub zog txhua yam, thiab hauv pem teb smoothness ntawm thermoplastic 3-D qhia cov ntsiab lus.
Hlau thiab ceramic slurries
Hlau thiab ceramic feem ntau ua raws li tag nrho 3-D luam ntawv yuav tsum tau siv cov ntaub ntawv inorganic slurries ua cov ntaub ntawv luam ntawv. Cov dej haus tshuaj lom neeg ua haujlwm hauv kev sib cais, stabilizing, thiab shaping lub slurry, kom paub tseeb tias cov slurry muaj zoo meej rheological, ziab, thiab sintering nyob. Cov txheej txheem raug cai ntawm cov dej haus tshuaj ua ke nrog cov surfactants thiab cov nplaum yog qhov tseem ceeb rau kev tsim thawj tus nqi hlau lossis ceramic 3-D qhia cov ntsiab lus.
Functional Cheebtsam
Ntxiv rau cov ntaub ntawv luam tawm thawj zaug, ob peb lub hom phiaj ua kua tshuaj lom neeg kuj tseem ua haujlwm tseem ceeb hauv 3-D luam ntawv. Cov tshuaj tua kab mob, cov nplaim hluav taws, cov khoom siv hluav taws xob, thiab lwm yam tuaj yeem ua rau 3-D qhia cov ntsiab lus nrog cov chaw nyob tshwj xeeb. Qhov kev ua kom zoo dua ntawm cov khoom siv ib zaug cuam tshuam rau lub hom phiaj tag nrho kev ua tau zoo ntawm qhov kawg tau qhia tawm.
