Cov khoom siv pab hnov lus, cov khoom tiv thaiv qhov ncauj, cov hniav cog, thiab lwm yam qauv uas ua raws li qhov xav tau feem ntau yog cov khoom ntawm kev luam ntawv 3D. Cov qauv no feem ntau yog ua los ntawm kev siv vat photopolymerization.—ib hom kev luam ntawv 3D uas siv cov qauv ntawm lub teeb los ua kom cov resin khov thiab ua kom khov, ib txheej zuj zus.
Cov txheej txheem kuj tseem cuam tshuam nrog kev luam tawm cov qauv txhawb nqa los ntawm tib cov khoom siv los tuav cov khoom kom ruaj khov raws li nws's luam tawm. Thaum cov khoom tiav lawm, cov kev txhawb nqa raug tshem tawm ntawm tes thiab feem ntau pov tseg ua cov khib nyiab tsis siv tau.
Cov kws ua haujlwm ntawm MIT tau pom ib txoj hauv kev los hla qhov kauj ruam kawg no, uas yuav ua rau cov txheej txheem luam ntawv 3D sai dua. Lawv tau tsim cov resin uas hloov mus ua ob hom khoom sib txawv, nyob ntawm seb hom teeb ci ntsa iab rau nws: Lub teeb ultraviolet kho cov resin kom ua cov khoom khov kho, thaum lub teeb pom kev hloov cov resin tib yam mus ua cov khoom khov kho uas yooj yim yaj hauv qee cov kuab tshuaj.
Cov pab pawg tau muab cov resin tshiab rau tib lub sijhawm rau cov qauv ntawm lub teeb UV los tsim ib lub qauv ruaj khov, nrog rau cov qauv ntawm lub teeb pom kev zoo los tsim cov qauv.'s cov kev txhawb nqa. Es tsis txhob yuav tsum tau ua tib zoo rhuav cov kev txhawb nqa, lawv tsuas yog muab cov ntaub ntawv luam tawm rau hauv cov tshuaj uas yaj cov kev txhawb nqa tawm, qhia txog qhov ruaj khov, UV-luam tawm.
Cov kev txhawb nqa tuaj yeem yaj rau hauv ntau yam kev daws teeb meem uas muaj kev nyab xeeb rau zaub mov, suav nrog cov roj menyuam yaus. Qhov nthuav yog tias cov kev txhawb nqa tuaj yeem yaj rau hauv cov khoom xyaw tseem ceeb ntawm cov resin qub, zoo li lub voos xwmfab dej khov hauv dej. Qhov no txhais tau tias cov khoom siv los luam cov kev txhawb nqa qauv tuaj yeem rov ua dua tshiab tas li: Thaum ib qho qauv luam tawm'cov khoom txhawb nqa yaj, qhov sib tov ntawd tuaj yeem sib xyaw ncaj qha rov qab mus rau hauv cov resin tshiab thiab siv los luam cov khoom tom ntej.—nrog rau lawv cov kev txhawb nqa yaj tau.
Cov kws tshawb nrhiav tau siv txoj kev tshiab los luam tawm cov qauv nyuaj, suav nrog cov iav ua haujlwm thiab cov lattices nyuaj.
