2. Sebelisa mohlala oa SLA bakeng sa tlhahiso e nyane ea methapo

Ho na le lintlha tse peli tsa mantlha tse lokelang ho tsotelloa tlhahisong e nyane ea methapo ea li-castings tse nepahetseng ho sebelisoa mekhoa ea SLA: e 'ngoe ke ho nepahala ha sebopeho seo moetso le ho lahla ho ka se fihlellang,' me e 'ngoe ke hore na litšenyehelo tsa tlhahiso le nako ea ho fana li na le melemo. Limela tse 'maloa tsa ho lahla ka nepo United States, joalo ka Solidiform, Nu-Cast, PCC le Uni-Cast, li sebelisitse lipaterone tsa SLA ho etsa li-castings tse makholo. Kamora litekanyo tsa 'nete tsa boholo ba ho lahla, tlhahlobo ea lipalo e bonts'a hore lehoakhoa le lecha la 11120 le folisang leseli le ntlafalitsoeng ke DSM Somos lea sebelisoa. Ka theknoloji ea QuickCast, paterone ea SLA e hlahisoang e na le kheloho ea boholo bo sa feteng 50% ea boleng ba mamello. Boholo ba li-castings tse ngata bo fihlela litlhoko tsa mamello, mme sekhahla sa ho feta se feta 95% (Setšoantšo sa 12-4) [7].

Le ha litjeo tsa ho etsa paterone ea SLA li phahame haholo ho feta tsa ho etsa hlobo e tšoanang ea boka, mme ho nka nako e teletsana, empa ha ho na tlhoko ea ho rala le ho etsa profiling. Ka hona, ha sengoathoana se le seng se hlahisoa ka lihlopha tse nyane, litšenyehelo le nako ea ho fana e ntse e le Melemo. Ha ho lahla ho rarahane haholoanyane, monyetla ona o totobala haholoanyane. Nka foromo e rarahaneng e bōpehileng joaloka lifofane e hlahisitsoeng ke Nu-Cast e le mohlala (Setšoantšo sa 12-5) [7], litšenyehelo tsa ho etsa hlobo li ka ba lidolara tse 85,000 tsa Amerika, hlobo ea boka ba 4 e hlahisoa letsatsi ka leng, le litšenyehelo tsa boka ka bong hlobo (ho kenyeletsoa lisebelisoa le Mosebetsi) 150 USD. Haeba mokhoa oa SLA o sebelisoa, mofuta o mong le o mong oa SLA o bitsa lidolara tsa US tsa 2846, empa ha ho na tlhoko ea ho rala le ho etsa hlobo. Ho latela palo ena, haeba sehlahisoa se le ka tlase ho likotoana tse 32, litšenyehelo tsa ho sebelisa hlobo ea SLA li tlase ho feta tsa hlobo ea boka; haeba likotoana tse fetang 32, theko e phahame ho feta hlobo ea boka (Setšoantšo sa 12-6); ho sebelisa hlobo ea boka, ho nka libeke tsa 14-16 ho rala le ho etsa hlobo, Mme hlobo ea SLA ha e hloke hlobo. Ka hona, haeba tlhahiso e le ka tlase ho likotoana tse 87, ho sebelisoa hlobo ea SLA, phetiso ea castings e potlakile ho feta hlobo ea boka (Setšoantšo sa 12-7). Empa likotoana tse fetang 87, hlobo ea boka e potlakile [7]. Ntlha e ngoe e hlokang ho tsotelloa ke hore haeba ho sebelisoa hlobo ea boka, ha sehlahisoa se nchafatsoa, ​​hlobo e hloka ho etsoa bocha, e leng theko e boima; ha a ntse a le ponahalo ea SLA, sohle se lokelang ho etsoa ke ho fetola mofuta oa CAD oa jiometri, o bonolo haholo ebile o potlaka ho feta ho etsa hlobo bocha. .
