Nhanganyaya:
Iyo minda yekuwedzera yekugadzira uye nekukurumidza prototyping yaona shanduko dzakakosha nekuda kwekupwanya kwepasi3D kudhinda tekinorojiinozivikanwa sestereolithography (SLA). Chuck Hull akagadzira SLA, rudzi rwekutanga kudhinda kwe3D, muma1980. Isu,FCE, inokuratidza zvese nezve maitiro uye mashandisirwo esterolithography mune ino chinyorwa.
Nheyo dzeStereolithography:
Chaizvoizvo, stereolithography ndiyo maitiro ekuvaka matatu-dimensional zvinhu kubva kudhijitari modhi akaturikidzana. Kusiyana nemaitiro echinyakare ekugadzira (akadaro ekugaya kana kuveza), ayo anowedzera zvinhu imwe layer panguva, 3D kudhinda-kusanganisira sterolithography-inowedzera zvinhu layer by layer.
Matatu akakosha pfungwa mune sterolithography inodzorwa stacking, resin kurapa, uye photopolymerization.
Photopolymerization:
Maitiro ekuisa mwenje kune resin yemvura kuishandura kuita yakasimba polymer inonzi photopolymerization.
Photopolymerizable monomers uye oligomers aripo mune resin inoshandiswa mune stereolithography, uye anoita polymeri kana akafumurwa kune mamwe mwenje wavelengths.
Resin Kurapa:
A vat yemvura resin inoshandiswa senzvimbo yekutanga kudhinda kwe 3D. Chikuva chiri pazasi pevheti inonyudzwa muresin.
Zvichienderana nemhando yedhijitari, UV laser beam inosarudzika inoomesa resin yemvura yakaturikidzana sezvainoongorora nzvimbo yayo.
Iyo nzira yepolymerization inotangwa nekunyatso kuburitsa resin kune UV mwenje, iyo inoomesa iyo mvura kuita coating.
Controlled Layering:
Mushure mega rega rakasimba, chikuva chekuvaka chinosimudzwa zvishoma nezvishoma kuratidza uye kurapa rinotevera resin.
Layer by layer, maitiro aya anoitwa kusvika iyo yakazara 3D chinhu chagadzirwa.
Digital Model Kugadzirira:
Uchishandisa komputa-inobatsira dhizaini (CAD) software, yedhijitari 3D modhi inogadzirwa kana kuwanikwa kuti itange 3D kudhinda maitiro.
Kucheka:
Imwe neimwe yakatetepa yemhando yedhijitari inomiririra muchinjiko-chikamu chechinhu chakapedzwa. Iyo 3D printer inorairwa kudhinda zvimedu izvi.
Kudhinda:
Iyo 3D printer inoshandisa stereolithography inogamuchira yakachekwa modhi.
Mushure mekunyudza chikuva chekuvaka mune resin yemvura, resin inorapwa zvine mutsindo nedhiza uchishandisa UV laser zvinoenderana nemirairo yakachekwa.
Post-Processing:
Mushure mokunge chinhu chacho chadhindwa muzvikamu zvitatu, zvinonyatsotorwa kubva mumucheka wemvura.
Kuchenesa resin yakawandisa, kuwedzera kurapa chinhu, uye, mune mamwe mamiriro, kugezesa kana kupururudza kuti ipedze yakapfava yese mienzaniso yekumashure-kugadzirisa.
Zvishandiso zveStereolithography:
Stereolithography inowana zvikumbiro mumaindasitiri akasiyana siyana, kusanganisira:
· Prototyping: SLA inoshandiswa zvakanyanya kukurumidza prototyping nekuda kwekugona kwayo kuburitsa yakatsanangurwa uye yakaringana modhi.
· Kuvandudza Chigadzirwa: Inoshandiswa mukuvandudza chigadzirwa kugadzira prototypes yekusimbisa dhizaini uye kuyedzwa.
· Mienzaniso yezvokurapa: Munzvimbo yezvokurapa, stereolithography inoshandiswa kugadzira maitiro akaomarara eanatomical ekuronga kuvhiya nekudzidzisa.
· Tsika Kugadzira: Iyo tekinoroji inoshandiswa kugadzira zvakagadziridzwa zvikamu uye zvikamu zvemaindasitiri akasiyana.
Mhedziso:
Tekinoroji dzemazuva ano dzekudhinda dze3D, dzinopa huchokwadi, kumhanya, uye kuita zvakasiyana-siyana mukugadzirwa kwezvinhu zvakaomarara zvine mativi matatu, dzakagoneswa nestereolithography. Stereolithography ichiri chikamu chakakosha chekuwedzera kugadzira, kubatsira kuvandudza maindasitiri mazhinji sekufambira mberi kwehunyanzvi.
