I-JS Additive inolwazi olusebenzayo lweminyaka ezinsizeni zokuphrinta ze-3D.Ngokucwaninga, kwatholakala ukuthi kunezici eziningi ezithinta ngqo isivinini sokubumba sokuphrinta kwe-SLA/DLP/LCD 3D.Ukusetha isivinini esifanelekile sokuphrinta kuyasiza ekuthuthukiseni amathuba okuphrinta ngempumelelo nokwenza kahle.Kodwa akulula kangako, ikakhulukazi isandla esisha.Ngaphambi kokusetha isivinini esifanelekile sokuphrinta, udinga ukwazi ukuthi yiziphi izici ezithinta isivinini sokuphrinta samaphrinta we-SLA/DLP/LCD 3D.
Ubuchwepheshe bokuphrinta
Uma kuqhathaniswa ne-SLA, i-DLP ne-LCD inenzuzo efanayo, futhi lokho isivinini sokuphrinta.Lobu buchwepheshe bokuphrinta obubili ngokusobala bushesha.Ngoba amaphrinta e-DLP/LCD 3D akheka endaweni yonke, eyakhiwe ngokushanela, ngokungafani ne-SLA, eyakhiwe ngamachashazi e-laser.

Isakhiwo sephrinta ye-LCD 1 umthombo wokukhanya 2 ilensi egxilile 3 Ilensi yeFresnel 4 ifilimu egqamile 5 Isikrini se-LCD 6 ifilimu ebabazekayo 7 ithangi eliwuketshezi eliphansi ifilimu 8 i-resin ephathekayo 9 i-pallet yokubumba epholile
Izilungiselelo Zephrinta
Uma isivinini sokuphrinta sisethwe kusengaphambili, ngeke sidlule inani elimisiwe.
Esinye isici esihlobene nesivinini sokuphrinta isivinini lapho isistimu iphrinta khona isendlalelo esisodwa.Lapho uphrinta, umthombo wokukhanya udlula ngaphansi komkhombe we-resin okhanyayo, futhi inhlaka esanda kwelashwa idinga inqubo eyisicefe yokuxebuka ngaphambi kokuqhubeka nokwelapha ungqimba olusha.Abanye abakhiqizi benza uhlelo ludlule enqubweni yokucwecwa ngokushesha ukuze kwandiswe isivinini sokuphrinta.Enye indlela yokuqeda lokhu kuhlupheka ukwelapha phezulu kwezinga le-resin, hhayi phansi.
Amandla Omthombo Wokukhanya
Ukuphrinta kwe-resin kusebenzisa umthombo wokukhanya ukuze kwelaphe inhlaka ewuketshezi ethatha izithombe ukuze idale imodeli yokugcina ye-3D.
Umehluko phakathi kwamasu amathathu umthombo wokukhanya osetshenziselwa ukwelapha i-resin.
Ukuqina komthombo wokukhanya osetshenzisiwe bungathinta isivinini sokuphrinta sephrinta.Singayithuthukisa ngokwandisa amandla okukhanya, kodwa lokho futhi kusho izindleko ezengeziwe.
IsendlaleloTukukhuphuka
Ukujiya kwesendlalelo kuthinta kokubili isivinini sokuphrinta nekhwalithi yemodeli.Ugqinsi lwesendlalelo oludingekayo ukuze uphrinte imodeli lunquma isivinini sokuphrinta nesikhathi esisithathayo.Uma ugqinsi lwesendlalelo luba mncane, kuzothatha isikhathi esiningi ukuphrinta imodeli ye-3D yobude obufanayo.Ngenxa yokuthi ubude obuphelele buhlala bufana, lapho ugqinsi lwesendlalelo luba mncane, iphrinta idinga izendlalelo eziningi ukuze iphrinte, futhi kuthatha isikhathi esiningi.Kodwa uma kuqhathaniswa, ukuqina kongqimba oluncane, kukhuphuka izinga lomkhiqizo oqediwe.

Okubalulekile
Ijubane lokuphrinta lephrinta ye-3D nalo lincike ohlotsheni lwezinto.Ama-resin ahlanganiswe ama-monomer ahlukene, ama-prepolymers, ama-photoinitiators, nezinye izithasiselo ezihlukahlukene anezakhiwo ezahlukene kanye nezikhathi zokwelashwa ezihlukene.
Isakhiwo Nokubekwa Kwemodeli
Ukwakheka kwemodeli nakho kuthinta isivinini sokuphrinta.Uma imodeli igobile futhi ingenayo imininingwane eyinkimbinkimbi, ukuphrinta kuyashesha kakhulu.Ukubekwa okunengqondo kwemodeli kuzophinde kuthinte isivinini sokuphrinta.Ngokuvamile, kuzoshesha kakhulu ukubeka imodeli ngokuvundlile kunokuma mpo lapho uphrinta, kodwa ukunemba kungase kuncishiswe.
Lezi izinto eziyinhloko ezithinta isivinini sokuphrinta phakathi kokuphrinta kwe-3D.Enqubweni yokukhiqiza okungeziwe, isimo sangempela singase sibe nzima kunalokho.Ngakho-ke, isivinini sokuphrinta siwukuhwebelana.Uma isivinini sokuphrinta sikhuphuka, kungenzeka ukuthi ikhwalithi yokuphrinta izokwehla.Indlela yokukala okuhle nokubi nayo idinga ukunqunywa ngokwesimo sangempela.
