Ịghọta Stereolithography: Banye n'ime teknụzụ mbipụta 3D

Okwu mmalite:
Akụkụ nke mmepụta ihe mgbakwunye na ngwa ngwa prototyping ahụla mgbanwe dị ịrịba ama n'ihi nkwụsị alaNkà na ụzụ obibi akwụkwọ 3Dmara dị kastereolithography (SLA). Chuck Hull kere SLA, ụdị mbipụta 3D mbụ, na 1980s. Anyị,FCE, ga-egosi gị nkọwa niile gbasara usoro na ngwa nke stereolithography n'isiokwu a.

Ụkpụrụ nke Stereolithography:
N'ụzọ bụ isi, stereolithography bụ usoro iwu ihe nwere akụkụ atọ site na oyi akwa ụdị dijitalụ. N'adịghị ka usoro mmepụta ihe a na-emekarị (dị ka igwe igwe ma ọ bụ ihe osise), nke na-agbakwunye ihe otu oyi akwa n'otu oge, mbipụta 3D-gụnyere stereolithography-na-agbakwụnye oyi akwa site na oyi akwa.
Echiche atọ dị mkpa dị na stereolithography bụ nchịkọta a na-achịkwa, ọgwụgwọ resin, na photopolymerization.

Photopolymerization:
Usoro nke itinye ìhè na resin mmiri mmiri iji mee ka ọ ghọọ polymer siri ike ka a na-akpọ photopolymerization.
Photopolymerizable monomers na oligomers dị na resin eji na stereolithography, na ha na-polymerize mgbe ekpughere ụfọdụ ìhè wavelengths.

Ngwọta resin:
A na-eji vat nke resin mmiri mee ihe dị ka ebe mmalite maka mbipụta 3D. A na-emikpu ikpo okwu na ala nke vat ahụ na resin.
Dabere na ụdị dijitalụ, ọkụ laser UV na-ahọrọ nke ọma na-eme ka oyi akwa resin mmiri sie ike site na oyi akwa ka ọ na-enyocha elu ya.
A na-amalite usoro polymerization site na iji nlezianya kpughee resin na ìhè UV, nke na-eme ka mmiri sie ike n'ime mkpuchi.
Nkwadebe a na-achịkwa:
Mgbe oyi akwa nke ọ bụla gbasie ike, a na-eji nwayọọ nwayọọ na-ebuli elu ikpo okwu iji kpughee ma gwọọ oyi akwa resin na-esote.
Layer site na oyi akwa, a na-eme usoro a ruo mgbe emepụtara ihe 3D zuru ezu.
Nkwadebe Nlereanya Dijitalụ:
Iji kọmpụta na-enyere aka imewe (CAD) ngwanrọ, a na-emepụta ma ọ bụ nweta ụdị 3D dijitalụ iji malite usoro mbipụta 3D.

Iberibe:
Igwe oyibo ọ bụla dị mkpa nke ụdị dijitalụ na-anọchite anya akụkụ obe nke ihe emechara. A gwara onye nbipute 3D ka ọ bipụta mpekere ndị a.

Na-ebi akwụkwọ:
Ihe nbipute 3D nke na-eji stereolithography na-anata ụdị iberibe.
Mgbe imikpuchara ebe a na-ewu ihe n'ime resin mmiri mmiri, a na-edozi resin ahụ nke ọma site na oyi akwa site na iji laser UV dị ka ntuziaka ndị a kpara akpa.

Nhazi mgbe emechara:
Mgbe e bipụtachara ihe ahụ n'akụkụ atọ, a na-ewepụ ya nke ọma na resin mmiri mmiri.
ihicha resin ngafe, na-agwọta ihe ahụ n'ihu, yana, n'ọnọdụ ụfọdụ, ịcha ájá ma ọ bụ polishing maka imecha dị nro bụ ihe atụ niile nke nhazi nhazi.
Ngwa nke Stereolithography:
Stereolithography na-achọta ngwa n'ime ụlọ ọrụ dị iche iche, gụnyere:

· Prototyping: SLA bụ ọtụtụ ebe maka prototyping ngwa ngwa n'ihi ike ya imepụta ukwuu zuru ezu na ezi ụdị.
· Mmepe ngwaahịa: A na-arụ ọrụ na mmepe ngwaahịa iji mepụta prototypes maka nkwado imewe na nnwale.
· Ụdị ahụike: N'ihe gbasara ahụike, a na-eji stereolithography mepụta ụdị mgbagwoju anya maka nhazi na nkuzi ịwa ahụ.
· Nrụpụta omenala: A na-eji teknụzụ na-arụ ọrụ iji mepụta akụkụ na akụrụngwa ahaziri maka ụlọ ọrụ dị iche iche.

Mmechi:
Teknụzụ ebipụta 3D ọgbara ọhụrụ, nke na-enye izi ezi, ọsọ na ịdị iche iche n'imepụta ihe dị mgbagwoju anya akụkụ atọ, mere ka o kwe omume site na stereolithography. Stereolithography ka bụ akụkụ bụ isi nke mmepụta ihe mgbakwunye, na-enyere aka ịmepụta ọtụtụ ụlọ ọrụ dị ka ọganihu teknụzụ.
