Thawj theem ntawm txoj kev tshawb no yog tsom rau kev xaiv ib lub monomer uas yuav ua raws li lub tsev thaiv rau cov polymer resin. Lub monomer yuav tsum yog UV-kho tau, muaj lub sijhawm kho luv luv, thiab tso saib cov khoom siv kho tshuab tsim nyog rau kev siv zog siab dua. Pab pawg, tom qab kuaj peb tus neeg sib tw muaj peev xwm, nws thiaj li txiav txim siab ntawm 2-hydroxyethyl methacrylate (peb tsuas yog hu nws HEMA).
Thaum lub monomer raug kaw, cov kws tshawb fawb tau tawm mus nrhiav qhov zoo tshaj plaws photoinitiator concentration nrog rau tus neeg sawv cev tsim nyog los ua khub HEMA rau. Ob hom photoinitiator tau sim rau lawv txoj kev txaus siab los kho raws li tus qauv 405nm UV teeb uas feem ntau pom hauv SLA systems. Cov photoinitiators tau muab tso rau hauv qhov sib piv 1: 1 thiab sib xyaw ntawm 5% los ntawm qhov hnyav rau qhov txiaj ntsig zoo tshaj plaws. Lub tshuab tshuab - uas yuav siv los pab txhawb kev nthuav dav ntawm HEMA cov qauv ntawm tes, ua rau 'ua npuas dej' - yog qhov nyuaj me ntsis los nrhiav. Ntau yam ntawm cov tshuaj ntsuam xyuas tsis zoo los yog nyuaj rau stabilize, tab sis pab neeg thaum kawg tau txiav txim siab ntawm cov tshuab tshuab tsis yog ib txwm siv nrog polystyrene zoo li polymers.
Qhov sib xyaw ua ke ntawm cov khoom xyaw tau siv los tsim qhov kawg photopolymer resin thiab pab pawg tau txais kev ua haujlwm ntawm 3D luam ntawv ob peb qhov tsis yooj yim CAD tsim. Cov qauv yog 3D luam tawm ntawm Anycubic Photon ntawm 1x nplai thiab rhuab ntawm 200 ° C txog li kaum feeb. Lub tshav kub decomposed tus neeg sawv cev tshuab, ua kom cov foaming nkaus ntawm cov resin thiab nthuav qhov loj ntawm cov qauv. Raws li kev sib piv qhov ntev ua ntej thiab tom qab nthuav dav, cov kws tshawb fawb tau suav cov kev nthuav dav txog li 4000% (40x), thawb cov qauv 3D luam tawm dhau los ntawm cov kev txwv qhov ntev ntawm Photon lub phaj tsim. Cov kws tshawb fawb ntseeg tias cov thev naus laus zis no tuaj yeem siv rau cov ntawv thov hnyav xws li aerofoils lossis buoyancy aids vim tias qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom.
