Kwinkqubo ye Ushicilelo lwe-3D, ngenxa yezinto ezahlukeneyo kuya kwenza ukuthontsiza ukubumba ukushwabana deformation, ulwakhiwo oluntsonkothileyo iipateni kufuneka inkqubo eyongezelelweyo inkxaso isakhiwo, isiphumo ileli yokubumba drip kufuneka athathe amanyathelo inkqubo ukunciphisa kunye nezinye izizathu, phambi kokuba imodeli iqumrhu lokuvelisa kufuneka ukuseta inkqubo ethile. amanyathelo okuguqula, ukulungelelanisa okanye ukubuyisela imodeli yedijithali.Kukho iindlela ezimbini eziphambili zokwenza umsebenzi, enye kukusebenza ngokuthe ngqo imodeli ye-CAD 3D, enye kukuguqula, okanye ukulungelelanisa idatha yendlela yokuskena, ngokulandelanayo ichazwe ngolu hlobo lulandelayo.
1. Sebenzisa ngokuthe ngqo iimodeli ze-CAD 3D
(1) Lungisa ulwalathiso lweepateni ngexesha lokuvelisa.
(2) Yandisa okanye unciphise iipateni.
(3) Yenza iipatheni ezininzi ngexesha elinye.
(4) Misela indawo yeepateni kwi-workbench yokuphakamisa.
2. Guqula okanye ulungise idatha yendlela yokuskena
Ukuze kuphuculwe ukuchaneka kokubunjwa, idatha yemodeli ye-three-dimensional ingatshintshwa kwaye ilungiswe, okanye idatha ye-scanning trajectory ye-shape-dimensional shape shape ingatshintshwa.
(1) Ulungiselelo oluchanekileyo:ibhekisa kulungiselelo lwemposiso ephezulu evumelekileyo phakathi kwenkangeleko yecandelo lemodeli eyiliweyo ye-dimensional ezintathu kunye neprofayile yokwenyani yokuskena yelaser beam kwinqwelomoya ye-XY.Impazamo encinci, ilula ngakumbi umphezulu wemveliso.
(2) Ukusetwa kobukhulu becandelo lecandelo leepateni:Xa ubukhulu becandelo bungatshintshi, i-Angle encinci phakathi komphezulu kunye ne-horizontal plane, isiphumo esikhulu sesinyathelo.Ngoko ke, ubukhulu becandelo elincinci bunokusetwa ngokwesikhokelo somzekelo kunye ne-Angle encinci phakathi kwendawo kunye nendiza ethe tye.
(3) Ukuskena i-trajectory offset:i-laser beam scanning contour inkulu kune-design contour, ukuze ukubunjwa kwe-drip kunomda wokucubungula;Okanye yenza iprofayile yokuskena ibe ncinci kuneprofayile yoyilo, ukuze ukubunjwa kwedriphu kube nomda wokugquma.
(4) Yongeza inkxaso yomqamelo ongezantsi:phakathi kwemodeli yequmrhu eliqulunqayo kunye neqonga lokunyusa kufuneka limisele umaleko wesakhelo sokuxhasa umqamelo osezantsi, ukwenzela ukuba imodeli esuka kwiqonga lokunyusela umgama omncinci wokwenza, ukwenzela ukuba iindawo zokubumba zingachaphazeli ukungalingani kweqonga.I-Underbed braces zizakhiwo ezifana neepleyiti ezincinci eziqiniweyo ukwenzela ukuba zisuswe ngokulula kwaye zisuswe kwimodeli yequmrhu emva kokuba yenziwe.
(5) Yongeza isakhelo kunye nenkxaso yekholamu:xa i-UV irradiation kwi-resin photocuring ukuyinyanga ngokupheleleyo, ngenxa yokucutheka kwe-resin yokunyanga, ukuze iindawo zikhubazeke kwinkqubo yokwakheka, kungakhathaliseki ukuba yeyiphi indlela esetyenziselwa ukulungisa kancinane indawo yokuvezwa kwe-resin, ingaba thintela ukuguqulwa kwezinto zokusebenza.
(6) Ukukhethwa kwendlela yokuskena:kukho iindlela ezintathu zentsimbi yelaser ukuskena icandelo, oko kukuthi, ukuskena ecaleni komda weprofayile yangaphandle yecandelo;Ukuskena isakhiwo selathisi yangaphakathi yenqatha lobusi ngaphandle kweencam zecontour;Uvavanyo lwangaphakathi lokuzalisa ngokunzulu.Ipateni enesakhiwo esiyinkimbinkimbi inokukhethwa, kwaye inkqubo yokuvelisa ibandakanya iindlela ezintathu zokuskena ezikhankanywe ngasentla.Unako nokuba usebenzise imodeli indibaniselwano kuquka ufakelo iswitshi, motor njalo njalo ukugqiba imveliso yayo, ukwenzela ukuvavanya formability.
Oku kungasentla kukwazisa indlela iSLA ukukhanya ukunyanga inkqubo yokubumba umshicileli we-3D kukuhlalutya,JS Ukongeza inokubonelela ngenkonzo yeprototyping ye-SLA eqolileyo.Ndiyathemba ukukunika ireferensi.
