I-resin enwebekayo yokunyathelisa ye-3D

Isigaba sokuqala socwaningo sasigxile ekukhetheni i-monomer ezosebenza njengebhloko yokwakha i-polymer resin. I-monomer kwakudingeka ilapheke nge-UV, ibe nesikhathi esifushane sokwelapha, futhi ibonise izakhiwo ezifiselekayo zemishini ezifanele ukusetshenziswa kwengcindezi ephezulu. Ithimba, ngemva kokuhlola abantu abathathu abangaba khona, ekugcineni lanquma ukusebenzisa i-2-hydroxyethyl methacrylate (sizoyibiza ngokuthi i-HEMA).

Lapho i-monomer isivaliwe, abacwaningi baqala ukuthola ukuhlushwa kwe-photoinitiator okufanele kanye ne-ejenti yokufutha efanele ukuhlanganisa i-HEMA nayo. Izinhlobo ezimbili ze-photoinitiator zahlolwa ukuthi zizimisele yini ukwelapha ngaphansi kwezibani ze-UV ezijwayelekile ezingama-405nm ezivame ukutholakala ezinhlelweni eziningi ze-SLA. Ama-photoinitiator ahlanganiswe ngesilinganiso esingu-1:1 futhi axutshwa ngo-5% ngesisindo ukuze kube nomphumela omuhle kakhulu. I-ejenti yokufutha - eyayizosetshenziselwa ukwenza kube lula ukwandisa isakhiwo seseli se-HEMA, okwaholela 'ekuphumeni kwegwebu' - kwakunzima kancane ukuyithola. Amaningi ama-ejenti avivinyiwe ayenganyibiliki noma kunzima ukuwaqinisa, kodwa ekugcineni iqembu lanquma i-ejenti yokufutha engeyona yendabuko evame ukusetshenziswa nama-polymer afana ne-polystyrene.

Ingxube eyinkimbinkimbi yezithako yasetshenziswa ukwakha i-resin yokugcina ye-photopolymer futhi ithimba laqala ukusebenza ekunyatheliseni i-3D imiklamo embalwa ye-CAD engeyona inkimbinkimbi kangako. Amamodeli aphrintiwe nge-3D ku-Anycubic Photon esikalini esingu-1x futhi ashiswa ku-200°C imizuzu efika kweyishumi. Ukushisa kwaqeda i-ejenti yokufutha, kwavuselela isenzo sokufutha kwe-resin futhi kwandisa usayizi wamamodeli. Lapho beqhathanisa ubukhulu bangaphambi nangemuva kokunwetshwa, abacwaningi babale ukwanda kwevolumu okufika ku-4000% (40x), besunduza amamodeli aphrintiwe nge-3D adlule imikhawulo yobukhulu bepuleti yokwakha ye-Photon. Abacwaningi bakholelwa ukuthi lobu buchwepheshe bungasetshenziswa ekusetshenzisweni okulula njenge-aerofoils noma izinsiza zokuntanta ngenxa yobuningi obuphansi kakhulu bezinto ezinwetshiwe.
