Gusobanukirwa Stereolithography: Kwibira muri tekinoroji yo gucapa 3D

Iriburiro:
Imirima yinyongera yinganda hamwe na prototyping byihuse yabonye impinduka zikomeye tubikeshaUbuhanga bwo gucapa 3Dbizwi nkastereolithography (SLA). Chuck Hull yakoze SLA, ubwoko bwa mbere bwo gucapa 3D, mu myaka ya za 1980. Twebwe,FCE, izakwereka ibisobanuro byose bijyanye nuburyo bukoreshwa hamwe na stereolithography muriyi ngingo.

Amahame ya Stereolithography:
Icyibanze, stereolithography ninzira yo kubaka ibintu bitatu-bingana kuva muburyo bwa digitale kumurongo. Bitandukanye nubuhanga busanzwe bwo gukora (nko gusya cyangwa kubaza), byongeramo ibikoresho icyarimwe, icapiro rya 3D - harimo na stereolithography - ryongeramo ibintu kumurongo.
Ibintu bitatu by'ingenzi muri stereolithographe bigenzurwa gutondeka, gukiza resin, no gufotora.

Photopolymerisation:
Inzira yo gukoresha urumuri kumazi kugirango ihindurwe polymer ikomeye yitwa Photopolymerisation.
Photopolymerizable monomers na oligomers biboneka muri resin ikoreshwa muri stereolithography, kandi ikora polymerize iyo ihuye nuburebure bwumucyo.

Gukiza Resin:
Vat ya resin yamazi ikoreshwa nkintangiriro yo gucapa 3D. Umwanya uri munsi ya vatiri winjijwe muri resin.
Ukurikije icyitegererezo cya digitale, urumuri rwa UV laser rwatoranije rukomera rwamazi ya resin kumurongo uko isuzuma hejuru.
Uburyo bwa polymerisation butangizwa no kwerekana witonze ibisigazwa byumucyo UV, bigakomera mumazi.
Igenzurwa:
Nyuma yuko buri cyiciro kimaze gukomera, kubaka kubaka bizamurwa buhoro buhoro kugirango bishyire ahagaragara kandi bikize urwego rukurikira rwa resin.
Inzira kumurongo, iyi nzira irakorwa kugeza ikintu cya 3D cyuzuye.
Gutegura Icyitegererezo cya Digital:
Ukoresheje porogaramu ifashwa na mudasobwa (CAD), uburyo bwa 3D bwa digitale burarema cyangwa bugurwa kugirango utangire inzira yo gucapa 3D.

Gukata:
Buri cyerekezo cyoroshye cya digitale yerekana guhuza ibice byarangiye. Mucapyi ya 3D asabwa gucapa ibice.

Gucapa:
Mucapyi ya 3D ikoresha stereolithography yakira moderi yaciwe.
Nyuma yo kwibiza muri platifomu yubaka mumazi ya resin, resin ikizwa muburyo butandukanye ukoresheje lazeri ya UV ukurikije amabwiriza yaciwe.

Nyuma yo gutunganya:
Ikintu kimaze gucapurwa mubipimo bitatu, bivanwa mubwitonzi mumazi.
Kwoza resin irenze, gukomeza gukiza ikintu, kandi, mubihe bimwe na bimwe, umusenyi cyangwa gusya kugirango birangire neza ni ingero zose nyuma yo gutunganywa.
Porogaramu ya Stereolithography:
Stereolithography isanga porogaramu mu nganda zitandukanye, harimo:

· Prototyping: SLA ikoreshwa cyane muburyo bwihuse bwa prototyping kubera ubushobozi bwayo bwo gukora moderi zirambuye kandi zuzuye.
· Gutezimbere Ibicuruzwa: Ikoreshwa mugutezimbere ibicuruzwa kugirango ikore prototypes yo kwemeza no kugerageza.
· Icyitegererezo cyubuvuzi: Mu rwego rwubuvuzi, stereolithography ikoreshwa mugukora imiterere igoye ya anatomique yo gutegura kubaga no kwigisha.
· Gukora ibicuruzwa: Ikoranabuhanga rikoreshwa mugukora ibice byabigenewe hamwe nibigize inganda zitandukanye.

Umwanzuro:
Ikoranabuhanga rya kijyambere rya 3D, ritanga ubunyangamugayo, umuvuduko, hamwe nuburyo bwinshi mugukora ibintu bigoye cyane-bitatu, byashobokaga na stereolithography. Stereolithography iracyari igice cyingenzi cyinganda ziyongera, zifasha guhanga inganda zitandukanye uko ikoranabuhanga ritera imbere.
