M'kati mwa Kusindikiza kwa 3D, chifukwa cha zinthu zosiyanasiyana adzapanga kukapanda kukapanda akamaumba shrinkage mapindikidwe, dongosolo zovuta za dongosolo ayenera zina ndondomeko thandizo dongosolo, zotsatira za makwerero akapanda kuleka akamaumba ayenera kutenga ndondomeko miyeso kuchepetsa ndi zifukwa zina, pamaso kupanga bungwe chitsanzo ayenera kukhazikitsa njira zina ndondomeko kusintha, kusintha kapena kubweza chitsanzo digito. Pali njira ziwiri zazikulu zogwirira ntchito, imodzi ndiyo kugwiritsa ntchito mwachindunji chitsanzo cha CAD 3D, chinacho ndikusintha, kapena kusintha deta ya jambulani, motsatana ndikufotokozera motere.
1. Mwachindunji gwiritsani ntchito zitsanzo za CAD 3D
(1) Sinthani mayendedwe amachitidwe panthawi yopanga.
(2) Onjezani kapena kuchepetsa mapatani.
(3) Pangani mapangidwe angapo nthawi imodzi.
(4) Khazikitsani malo azithunzi pa benchi yonyamulira.
2. Sinthani kapena sinthani njira yosanthula deta
Pofuna kukonza kulondola kwa mapangidwe, deta yachitsanzo chamagulu atatu ikhoza kusinthidwa ndi kusinthidwa, kapena deta ya scanning trajectory ya mawonekedwe atatu-dimensional mawonekedwe akhoza kusinthidwa.
(1) Kukonzekera kolondola:zimatanthawuza kukhazikitsidwa kwa cholakwika chachikulu chovomerezeka pakati pa gawo lachitsanzo cha mbali zitatu chomwe chapangidwa ndi mawonekedwe enieni a mtengo wa laser pa ndege ya XY. Cholakwika chaching'ono, pamwamba pake chimakhala chosalala.
(2) Gawo la makulidwe a gawo la magawo:Pamene makulidwe a gawo ndi osasinthasintha, ang'onoang'ono Angle pakati pa ndege ndi yopingasa, ndiye kuti zotsatira zake zimakhala zazikulu. Choncho, makulidwe ang'onoang'ono a gawo akhoza kukhazikitsidwa motsatira malangizo a chitsanzo ndi Angle yaying'ono pakati pa pamwamba ndi ndege yopingasa.
(3) Kusanthula kwa trajectory offset:laser mtengo kupanga sikani contour ndi yayikulu kuposa kapangidwe kameneka, kotero kuti drip ikawumbidwa imakhala ndi malire; Kapena pangani mbiri yojambulira kukhala yaying'ono kuposa mawonekedwe apangidwe, kuti madontho apangidwe akhale ndi malire.
(4) Onjezani chithandizo chapansi cha khushoni:pakati pa kupanga gulu chitsanzo ndi kukweza nsanja ayenera kukhazikitsa wosanjikiza pansi khushoni thandizo chimango, kuti chitsanzo kuchokera kukweza nsanja mtunda pang'ono kupanga, kotero kuti kupanga mbali sakhudzidwa ndi kukweza nsanja kusamvana. Zingwe zapansi pa bedi ndi zomangika zomwe zimafanana ndi mbale zoonda zolimba kuti zitha kuchotsedwa mosavuta ndikuchotsedwa pamtundu wazinthu zitapangidwa.
(5) Onjezani chimango ndi gawo lothandizira:pamene UV walitsa pa photocuring utomoni kuchiza kwathunthu, chifukwa shrinkage wa machiritso utomoni, kotero kuti mbali adzakhala opunduka mu kupanga ndondomeko, ziribe kanthu njira ntchito pang'ono kukonza kukhudzana mbali ya utomoni, zingalepheretse mapindikidwe a workpieces.
(6) Kusankha njira yojambulira:pali njira zitatu zowunikira gawo la laser, zomwe ndi, kusanthula m'mphepete mwa mawonekedwe akunja a gawolo; Kusanthula m'mbali mwa zisa za uchi kupatula m'mphepete; Mkati kwambiri kudzaza sikani. Chitsanzo chokhala ndi dongosolo lovuta likhoza kusankhidwa, ndipo njira yopangira ikuphatikizapo njira zitatu zowunikira zomwe tazitchula pamwambapa. Itha kugwiritsa ntchito mtundu wophatikiza kuphatikiza kuyika chosinthira, mota ndi zina zambiri kuti amalize kupanga kwake, kuti ayese mawonekedwe ake.
Pamwambapa ndikuwonetsa momwe aSLA kuwala kuchiritsa 3D chosindikizira akamaumba ndondomeko ndi kusanthula,Chithunzi cha JSADD 3D imatha kupereka okhwima ngati SLA prototyping service. Ndikuyembekeza kukupatsirani chidziwitso.
