Isigaba sokuqala sophononongo sasijolise ekukhetheni i-monomer eya kusebenza njengebhloko yesakhiwo se-polymer resin. I-monomer kwafuneka ukuba i-UV-inonyangeka, ibe nexesha elifutshane lokunyanga, kwaye ibonise iipropati ezinqwenelekayo zoomatshini ezifanelekileyo kwizicelo ezinoxinzelelo oluphezulu. Iqela, emva kokuvavanya abaviwa abathathu, ekugqibeleni bahlala kwi-2-hydroxyethyl methacrylate (siya kuyibiza nje ngokuba yi-HEMA).
Nje ukuba i-monomer itshixiwe ngaphakathi, abaphandi bazimisela ukufumana eyona nto ilungileyo yokufota ifoto kunye nearhente yokuvuthela efanelekileyo ukubhanqa i-HEMA kuyo. Iindidi ezimbini zefotoinitiator zavavanywa ukuba zikulungele na ukunyanga phantsi kwezibane ezisemgangathweni ze-405nm ze-UV eziqhele ukufunyanwa kwiinkqubo ezininzi ze-SLA. I-photoinitiators idibaniswe kwi-1: umlinganiselo we-1 kwaye ixutywe kwi-5% ngesisindo sesona siphumo siphezulu. I-arhente evuthelayo-eya kusetyenziswa ukwenza lula ukwandiswa kwesakhiwo seselula se-HEMA, esikhokelela 'ekuphumeni kwamagwebu' - yayiliqhinga elincinci ukuyifumana. Uninzi lweearhente ezivavanyiweyo zazinganyibiliki okanye kunzima ukuzinzisa, kodwa iqela ekugqibeleni lazinza kwi-arhente yokuvuthela engeyiyo eyesintu eqhelekileyo esetyenziswa ngeepolymers ezifana ne-polystyrene.
Umxube ontsonkothileyo wezithako wasetyenziselwa ukwenza i-resin ye-photopolymer yokugqibela kwaye iqela liye lasebenza kwi-3D yoshicilelo lwe-CAD olungelulo olunzima kangako. Iimodeli zaye zaprintwa kwi-Anycubic Photon kwi-1x isikali kwaye ishushu kwi-200 ° C ukuya kwimizuzu elishumi. Ubushushu bubolile i-agent evuthelayo, kusebenze isenzo sogwebu se-resin kunye nokwandisa ubungakanani beemodeli. Xa kuthelekiswa nemilinganiselo yangaphambili nasemva kokwandiswa, abaphandi babala ukwandiswa kwe-volumetric ukuya kwi-4000% (40x), betyhala iimodeli eziprintiweyo ze-3D ezidlulileyo kwimida ye-dimensional ye-Photon's building plate. Abaphandi bakholelwa ukuba obu buchwephesha bunokusetyenziselwa usetyenziso olukhaphukhaphu olunje nge-aerofoils okanye i-buoyancy aids ngenxa yoxinano oluphantsi kakhulu lwemathiriyeli eyandisiweyo.
