Esizindeni esikhulayo sokuphrinta kwe-3D, ingxenye eyodwa ikhule ngokuhambisana nokusebenza okubucayi - ilensi ye-F-Theta.Lolu cezu lwesisetshenziswa lubalulekile enqubweni eyaziwa ngokuthi i-Stereolithography (SLA), njengoba luthuthukisa ukunemba nokusebenza kahle kokuphrinta kwe-3D.
I-SLA iyindlela yokwenza okungeziwe ehlanganisa ukugxilisa i-laser ye-UV ku-vat ye-photopolymer resin.Isebenzisa ukukhiqiza okusizwa ngekhompyutha (i-CAM) noma isofthiwe ye-computer-aid design (CAD), i-UV laser ilandelela umklamo ohleliwe endaweni yeresin.Uma kubhekwa ukuthi ama-photopolymer aqina lapho echayeke ekukhanyeni kwe-ultraviolet, iphasi ngayinye ye-laser yakha ungqimba oluqinile lwento ye-3D efiselekayo.Inqubo iphindaphindiwe kungqimba ngalunye kuze kube yilapho into igcwaliseka ngokugcwele.
I-F-Theta Lens Advantage
Ngokolwazi oluqoqwe kwaIwebhusayithi kaCarman HaasAmalensi e-F-Theta, kanye nezinye izingxenye ezifana ne-expander ye-beam, ikhanda le-gavlo nesibuko, akha isistimu yokubona yamaphrinta e-SLA 3D, indawo enkulu yokusebenza ingaba ngu-800x800mm.
Ukubaluleka kwelensi ye-F-Theta kulo mongo akukwazi ukweqiwa.Idlala indima ebalulekile ekuqinisekiseni ukuthi ukugxila kwe-laser beam kuyahambisana kulo lonke indiza ye-photopolymer resin.Lokhu kufana kuqinisekisa ukwakheka kwento okunembayo, kususe amaphutha angenzeka ekugxilweni kwe-beam okungahambisani.
Imibono Ehlukahlukene Nokusetshenziswa
Amakhono ayingqayizivele amalensi e-F-Theta awenza abaluleke kakhulu emikhakheni ethembele kakhulu ekuphrinteni kwe-3D.Izimboni ezifana nokukhiqiza izimoto, i-aerospace, ubuchwepheshe bezokwelapha, ngisho nemfashini zisebenzisa amaphrinta e-3D afakwe amalensi e-F-Theta ukuze adale izingxenye eziyinkimbinkimbi, ezinembe kakhulu.
Kubaklami bemikhiqizo nabakhiqizi, ukufakwa kwelensi ye-F-Theta kunikeza umphumela obikezelwayo nongaguquguquki, kunciphisa ukumoshakala kwezinto ezibonakalayo nokwandisa ukusebenza kahle.Ekugcineni, lokhu kucaciswa konga isikhathi futhi kunciphisa izindleko, izici ezimbili ezibalulekile enqubweni yokukhiqiza eyimpumelelo.
Kafushane, amalensi e-F-Theta aneqhaza elikhulu emhlabeni othuthukayo wokuphrinta we-3D, enikeza ukunemba okudingekayo ukuze kudalwe izinto eziyinkimbinkimbi nezinemininingwane.Njengoba siqhubeka nokuhlanganisa ubuchwepheshe bokuphrinta be-3D emikhakheni eyengeziwe, isidingo sokunemba okuphezulu nokusebenza kahle sizoqinisa indima ebalulekile yamalensi e-F-Theta kulawa maphrinta.
Ukuze uthole ulwazi olwengeziwe, sicela uvakasheleUCarman Haas.
