Icapiro rya 3D ryaguka resin

Icyiciro cya mbere cyubushakashatsi cyibanze ku guhitamo monomer yakora nkigice cyo kubaka polymer resin. Monomer yagombaga kuba UV-ishobora gukira, ikagira igihe gito cyo gukira, kandi ikagaragaza imiterere yubukanishi ikwiranye nibisabwa cyane. Itsinda, nyuma yo kugerageza abakandida batatu bashobora kuba, amaherezo ryatuye kuri 2-hydroxyethyl methacrylate (tuzabyita HEMA).

Monomer imaze gufungwa, abashakashatsi bahisemo gushakisha uburyo bwiza bwo gufotora hamwe na agent ikwiye kugirango bahuze HEMA. Ubwoko bubiri bwa fotoinitiator bwageragejwe kubushake bwo gukira munsi yumucyo usanzwe wa 405nm UV ukunze kuboneka muri sisitemu nyinshi za SLA. Abafotora bahujwe mukigereranyo cya 1: 1 hanyuma bavangwa kuri 5% kuburemere kubisubizo byiza cyane. Umukozi uhuha - wakoreshwa mu koroshya iyaguka ryimiterere ya selile ya HEMA, bikavamo 'kubira ifuro' - byari amayeri make yo kubona. Benshi mubakozi bapimwe ntibashobora gukemuka cyangwa kugorana guhagarara, ariko itsinda ryarangije gutura kumashanyarazi adasanzwe gakondo akoreshwa na polymers.

Uruvangitirane ruvanze rwibikoresho rwakoreshejwe mugukora resin ya nyuma ya Photopolymer hanyuma itsinda ryabona akazi ko gucapisha 3D bike mubishushanyo mbonera bya CAD. Moderi yacapishijwe 3D kuri Anycubic Photon ku gipimo cya 1x kandi yashyutswe kuri 200 ° C mu minota icumi. Ubushyuhe bwangirika ibintu bivuza, gukora ibikorwa byo kubira ifuro ya resin no kwagura ubunini bwa moderi. Mugereranije ibipimo byabanjirije na nyuma yo kwaguka, abashakashatsi babaze ubwiyongere bwa volumetricike bugera kuri 4000% (40x), basunika moderi zacapwe 3D zirenze imbibi za plaque yubatswe. Abashakashatsi bemeza ko iryo koranabuhanga rishobora gukoreshwa mu gukoresha ibintu byoroheje nka aerofoil cyangwa ibikoresho bya buoyancy bitewe n'ubucucike buke cyane bw'ibikoresho byagutse.
