Ngohlelo lwe Ukuphrinta kwe-3D, ngenxa yezici ezihlukahlukene kuzokwenza ukuwohloka kokuncipha kwe-drip molding, isakhiwo esiyinkimbinkimbi samaphethini sidinga isakhiwo esingeziwe sokusekela inqubo, umphumela wesitebhisi wokubunjwa kwamaconsi udinga ukuthatha izinyathelo zenqubo yokunciphisa nezinye izizathu, ngaphambi kokuba imodeli yebhizinisi ekhiqizayo idinga ukusetha izinyathelo ezithile zenqubo yokuguqula, ukulungisa noma ukunxephezela imodeli yedijithali. Kunezindlela ezimbili eziyinhloko zokwenza umsebenzi, eyodwa iwukusebenzisa ngokuqondile imodeli ye-CAD 3D, enye iwukushintsha, noma ukulungisa idatha yendlela yokuskena, ngokulandelana okuchazwe kanje.
1. Sebenzisa ngokuqondile amamodeli e-CAD 3D
(1) Lungisa isiqondiso samaphethini ngesikhathi sokukhiqiza.
(2) Nweba noma unciphise amaphethini.
(3) Yenza amaphethini amaningi ngesikhathi esisodwa.
(4) Setha indawo yamaphethini ebhentshini lokusebenza eliphakamisayo.
2. Lungisa noma lungisa idatha yendlela yokuskena
Ukuze kuthuthukiswe ukunemba kokwakheka, idatha yemodeli yezinhlangothi ezintathu ingashintshwa futhi ilungiswe, noma idatha yomzila wokuskena womumo wesigaba esinezinhlangothi ezintathu ingashintshwa.
(1) Isilungiselelo sokunemba:ibhekisela ekumisweni kwephutha elikhulu elivumelekile phakathi kwephrofayela yesigaba semodeli yezinhlangothi ezintathu eklanyelwe kanye nephrofayela yangempela yokuskena ye-laser beam endizeni ye-XY. Iphutha lincane, ingaphezulu lomkhiqizo liba bushelelezi.
(2) Ukulungiselelwa kobukhulu besigaba kwesigaba samaphethini:Uma ukushuba kwesigaba kungashintshi, i-engeli encane phakathi kwendiza engaphezulu nendawo evundlile, umphumela wesinyathelo uba mkhulu. Ngakho-ke, ukushuba kwesigaba esincane kungasethwa ngokuvumelana nesiqondiso semodeli kanye ne-Angle encane phakathi kwendawo kanye nendiza evundlile.
(3) Iskena i-trajectory offset:i-laser beam scanning contour inkulu kune-contour yokuklama, ukuze ukubunjwa kwe-drip kube nomphetho wokucubungula; Noma yenza iphrofayela yokuskena ibe yincane kunephrofayili yokuklama, ukuze ukubunjwa kwama-drip kube nomphetho wokumboza.
(4) Engeza usekelo lomcamelo ongezansi:phakathi kwemodeli yebhizinisi eyakhayo kanye neplathifomu yokuphakamisa kudingeka kumiswe isendlalelo sohlaka olusekela umcamelo ongezansi, ukuze imodeli esuka endaweni yokuphakamisa ibe nebanga elincane ukwakha, ukuze izingxenye ezakhayo zingathintwa ukungalingani kwendawo yokuphakamisa. Izikaki ezingaphansi kombhede ziyizakhiwo ezifana namapuleti amancane aqinile ukuze akhishwe kalula futhi akhishwe kumodeli yebhizinisi ngemva kokwakhiwa.
(5) Engeza ukwesekwa kohlaka nekholomu:lapho i-UV irradiation ku-resin ye-photocuring ukuyiphulukisa ngokuphelele, ngenxa yokuncipha kwe-resin yokuphulukisa, ukuze izingxenye zizokhubazeka ekubunjweni kwenqubo, kungakhathaliseki ukuthi iyiphi indlela esetshenziselwa ukulungisa kancane ingxenye yokuchayeka ye-resin, ingavimbela ukuguqulwa kwezinto zokusebenza.
(6) Ukukhethwa kwendlela yokuskena:kunezindlela ezintathu zokuthi ugongolo lwe-laser luskene isigaba, okungukuthi, ukuskena emaphethelweni ephrofayili yangaphandle yesigaba; Ukuskena kwesakhiwo selathisi yangaphakathi yekhekheba lezinyosi ngaphandle kwemiphetho yamakhonta; Ukuskena kokugcwalisa okujulile kwangaphakathi. Iphethini enesakhiwo esiyinkimbinkimbi ingakhethwa, futhi inqubo yokukhiqiza ibandakanya izindlela zokuskena ezintathu ezishiwo ngenhla. Ingakwazi ngisho nokusebenzisa imodeli eyinhlanganisela ehlanganisa ukufakwa kweswishi, injini nokunye ukuze iqedele ukukhiqizwa kwayo, ukuze ihlole ukwakheka kwayo.
Lokhu okungenhla ukwethula indlela iI-SLA ukukhanya ukuphulukisa inqubo yokubumba iphrinta ye-3D ukuhlaziya,I-JSADD 3D ingahlinzeka ngensizakalo ye-prototyping ye-SLA evuthiwe. Ngethemba ukukunikeza ireferensi.
