Gabatarwa:
Filayen masana'anta masu ƙari da samfura cikin sauri sun ga manyan canje-canje godiya ga ƙaddamar da ƙasaFasahar bugu 3Daka sani dastereolithography (SLA). Chuck Hull ya kirkiro SLA, farkon nau'in bugu na 3D, a cikin 1980s. Mu,FCE, zai nuna maka duk cikakkun bayanai game da hanya da aikace-aikacen stereolithography a cikin wannan labarin.
Ka'idodin Stereolithography:
Ainihin, stereolithography shine tsarin gina abubuwa masu girma uku daga ƙirar dijital Layer ta Layer. Ya bambanta da fasahohin masana'antu na al'ada (irin su niƙa ko sassaƙa), waɗanda ke ƙara kayan abu ɗaya a lokaci guda, bugu na 3D - gami da stereolithography - yana ƙara ƙirar abu ta layi.
Mabuɗin maɓalli guda uku a cikin stereolithography ana sarrafa stacking, resin curing, da photopolymerization.
Photopolymerization:
Hanyar yin amfani da haske zuwa guduro ruwa don juya shi zuwa wani m polymer ana kiransa photopolymerization.
Monomers na Photopolymerizable da oligomers suna nan a cikin resin da ake amfani da su a cikin stereolithography, kuma suna yin polymerize lokacin da aka fallasa su zuwa wani tsayin haske na musamman.
Resin Curing:
Ana amfani da vat na resin ruwa azaman wurin farawa don buga 3D. Dandalin da ke ƙasan vat ɗin yana nutsewa cikin guduro.
Dangane da ƙirar dijital, katako na Laser UV yana zaɓi yana ƙarfafa Layer resin ruwa ta Layer yayin da yake duba saman sa.
Ana fara aikin polymerization ta hanyar fallasa resin a hankali zuwa hasken UV, wanda ke ƙarfafa ruwa a cikin rufi.
Sarrafa Layering:
Bayan kowane Layer ya ƙarfafa, ana ɗaga dandalin ginin a hankali don fallasa da kuma warkar da resin na gaba.
Layer ta Layer, ana aiwatar da wannan tsari har sai an samar da cikakken abu na 3D.
Shiri Na Dijital:
Yin amfani da software na ƙira mai taimakon kwamfuta (CAD), ana ƙirƙira ko samo samfurin 3D na dijital don fara aikin bugu na 3D.
Yanka:
Kowane bakin bakin ciki samfurin dijital yana wakiltar ɓangaren giciye na abin da aka gama. An umurci firinta na 3D don buga waɗannan yankan.
Bugawa:
Firintar 3D da ke amfani da stereolithography yana karɓar ƙirar da aka yanka.
Bayan nutsewa dandali na ginin a cikin guduro na ruwa, resin ɗin yana warkewa ta hanyar tsari ta hanyar Layer ta amfani da Laser UV daidai da umarnin yankakken.
Bayan Gudanarwa:
Bayan an buga abun cikin nau'i uku, ana fitar da shi a hankali daga resin ruwa.

Aikace-aikace na Stereolithography:
Stereolithography yana samun aikace-aikace a cikin masana'antu daban-daban, gami da:
Samfura: Ana amfani da SLA sosai don saurin samfuri saboda ikonsa na samar da cikakkun bayanai da ƙima.
· Haɓaka Samfur: Ana amfani da shi a cikin haɓaka samfur don ƙirƙirar samfura don ingantaccen ƙira da gwaji.
Samfuran Likitanci: A fannin likitanci, ana amfani da stereolithography don ƙirƙirar ƙayyadaddun tsarin halittar jiki don tsara tiyata da koyarwa.
· Manufacturing Custom: Ana amfani da fasahar don kera sassa da aka keɓance don masana'antu daban-daban.
Ƙarshe:
Fasahar bugu na 3D na zamani, waɗanda ke ba da daidaito, saurin gudu, da juzu'i a cikin samar da ƙaƙƙarfan abubuwa masu girma uku, an yi su ta hanyar stereolithography. Stereolithography har yanzu wani mahimmin ɓangaren masana'anta ne, yana taimakawa haɓaka masana'antu da yawa yayin da fasahar ke haɓaka.
