Isigaba sokuqala socwaningo sasigxile ekukhetheni i-monomer ezosebenza njengebhlokhi yokwakha i-polymer resin. I-monomer bekufanele yelapheke nge-UV, ibe nesikhathi esifushane sokwelapha, futhi ibonise izakhiwo ezifiselekayo zomshini ezifanele izinhlelo zokusebenza ezinokucindezeleka okuphezulu. Ithimba, ngemva kokuhlola abantu abathathu abangase bangenele ukhetho, ekugcineni lizinze ku-2-hydroxyethyl methacrylate (sizovele siyibize nge-HEMA).
Lapho i-monomer isivaliwe, abacwaningi baqala ukuthola ukugxiliswa kwe-photoinitiator okuphelele kanye ne-ejenti efuthayo efanelekile yokubhanqa i-HEMA nayo. Izinhlobo ezimbili ze-photoinitiator zahlolelwa ukuzimisela kwazo ukwelapha ngaphansi kwezibani ezijwayelekile ze-405nm UV ezivame ukutholakala kumasistimu amaningi we-SLA. Ama-photoinitiators ahlanganiswe ngesilinganiso esingu-1:1 futhi axutshwa ngo-5% ngesisindo ukuze kube nomphumela ofaneleka kakhulu. I-ejenti efuthayo - eyayizosetshenziswa ukusiza ukunwetshwa kwesakhiwo samaselula we-HEMA, okuholela 'ekukhihlizeni amagwebu' - kwaba iqhinga elincane ukulithola. Ama-ejenti amaningi ahloliwe ayengancibiliki noma kunzima ukuzinzisa, kodwa ithimba lagcina lizinze endaweni engeyona eyendabuko evuthela umoya ngokuvamile esetshenziswa nama-polymers afana ne-polystyrene.
Ingxube eyinkimbinkimbi yezithako yasetshenziswa ukwenza inhlaka yokugcina ye-photopolymer futhi ithimba laqala ukusebenza ekuphrinteni kwe-3D imiklamo embalwa ye-CAD engeyona inkimbi kangako. Amamodeli abeyi-3D aphrintwe ku-Anycubic Photon esikalini esingu-1x futhi ashisiswe ku-200°C kuze kube yimizuzu eyishumi. Ukushisa kwabolisa i-ejenti ephephethayo, kwavula isenzo esinegwebu se-resin futhi kwandise usayizi wamamodeli. Lapho beqhathanisa ubukhulu bangaphambi nangemuva kokunwetshwa, abacwaningi babale ukunwetshwa kwevolumu okungafika ku-4000% (40x), bephusha amamodeli aphrintiwe e-3D adlule imikhawulo yobukhulu yepuleti lokwakha le-Photon. Abacwaningi bakholelwa ukuthi lobu buchwepheshe bungasetshenziselwa izinhlelo zokusebenza ezingasindi ezifana ne-aerofoil noma izinsiza zokuvuselela ngenxa yokuminyana okuphansi kakhulu kwezinto ezinwetshiwe.
