Ukusetshenziswa kobuchwepheshe bokuphrinta be-3D embonini yezokwelapha yezwe lami kwaqala ngeminyaka yawo-1980. Ekuqaleni yayisetshenziselwa ukwenza amamodeli ezokwelapha anezinhlangothi ezintathu. Ngokuthuthukiswa kwemithi enembile kanye nemithi yomuntu siqu, ukusetshenziswa kobuchwepheshe bokuphrinta be-3D embonini yezokwelapha sekwande kakhulu.

 Kusukela kumamodeli anezinhlangothi ezintathu namathuluzi okuhlinza kuya ezicutshini eziphilayo ezitshalwe kabusha nezitho zomuntu, kuye emithini, ubuchwepheshe bokuphrinta be-3D buye bavuthwa kancane kancane. Mayelana nezidakamizwa, ubuchwepheshe bokuphrinta be-3D budlale indima ebalulekile. Isibonelo, ngo-2015, i-Aprecia Pharmaceuticals yakhiqiza iphilisi lokuqala elikhiqizwe ngobuchwepheshe bokuphrinta be-3D futhi yathola imvume ye-FDA.

Eminyakeni emibili kamuva, i-GlaxoSmithKline yaphothula ucwaningo isebenzisa ubuchwepheshe bokuphrinta be-inkjet 3D kanye ne-ultraviolet (UV) ukukhiqiza amaphilisi okwelapha isifo sika-Parkinson. Ngokusetshenziswa kokukhishwa okulawulwayo, izidakamizwa zesikhashana, kanye namandla okuphrinta endaweni emakhemisi, ikhono lobuchwepheshe bokuphrinta be-3D lokuguqula imboni yezemithi liyaqhubeka nokukhula. Kuyaqondakala ukuthi amalungiselelo okwelapha endabuko ayindlela yokuhlola namaphutha. Abacwaningi abafunda amalungiselelo bahlale bezama ukwenza iphutha ukuze bathole ingxenye ehambisanayo yefomula yezemithi, bese bethola umphumela othile.

"Ukulungiselela kwethu ukuphrinta kwe-3D ukufaka izinto zokusetshenziswa kanye nezinto ezisizayo futhi ziguqule zibe ukulungiswa ngokusebenzisa uchungechunge lwezinqubo. Imikhiqizo esiyenzayo njengamanje imithi engalawulwa ngokunembile." Umndeni ukholelwa ukuthi ubuchwepheshe bokuphrinta be-3D buyadingeka. Kunezinhlobo ezimbili eziyinhloko zezidakamizwa: eyodwa imithi enesidingo esithile sokukhululwa, kanti eyesibili amalungiselelo ayinhlanganisela ashesha kakhulu. Phakathi kwazo, emkhakheni wamalungiselelo emithi, ubuchwepheshe bokuphrinta be-3D obuyinhloko buhlanganisa ubuchwepheshe bomjovo we-binder, ubuchwepheshe be-extrusion yezinto ezibonakalayo, kanye ne-SLA.

Ubuchwepheshe be-binder jetting ubuchwepheshe obuyinhloko bokuphrinta be-3D obusetshenziselwa ukukhiqiza ukwakheka. Ngenxa yokufana okuningi nobuchwepheshe be-granulation obusetshenziswa ekukhiqizweni kwamalungiselelo endabuko, ubuchwepheshe bomjovo we-binder bunohlu olubanzi lwezinto ezingavuthiwe ozikhethela bona futhi bunethuba elibanzi lokufaka isicelo emalungiselelweni emithi.

Ubuchwepheshe be-Material extrusion ubuchwepheshe bokuphrinta be-3D obusetshenziswa kabanzi emhlabeni wonke, futhi ukunaka lobu buchwepheshe emkhakheni wamalungiselelo emithi nakho kuyanda. Ubuchwepheshe obujwayelekile be-extrusion yi-FDM. Uma kuqhathaniswa nobuchwepheshe bomjovo we-binder, i-FDM nezinye izinhlelo ze-extrusion zinemishini elula namandla okuklama umkhiqizo avumelana nezimo, ikakhulukazi ukwakheka kokwakheka kwemithi okuyinkimbinkimbi.

Ubuchwepheshe bokubumba bokuphulukisa ukukhanya kwe-stereo bungobunye bobuchwepheshe bokuqala bokuphrinta be-3D obuthengiswayo. Njengamanje, ubuchwepheshe bokubumba bokuphulukisa ukukhanya obunezinhlangothi ezintathu busetshenziswe ngempumelelo ekukhiqizeni i-prototype yobunjiniyela bezicubu kanye nezimila zokuhlinza ngokwezifiso. Kodwa-ke, ubuchwepheshe bokubumba bokuphulukisa ukukhanya obunezinhlangothi ezintathu bubuye bube nemikhawulo ethile, obuthiya ukusetshenziswa kwabo emkhakheni wokukhiqiza imithi. Isibonelo, ukusetshenziswa kwayo emalungiselelweni emithi kunqunyelwe izinto ze-biocompatible photopolymer.

Ngaphezu kwalokho, ukuphrinta kwe-3D nakho kunesithembiso esikhulu semithi yezintandane, eklanyelwe ukwelapha izifo ezingavamile ngezinye izikhathi ezingenakuthuthukiswa imboni yezemithi ngenxa yezizathu zezomnotho. Kulinganiselwa ukuthi inani lalesi sifo esingavamile lisukela ku-4,000 5,000 kuya ku-3 3 emhlabeni jikelele. Njengamanje, ubuchwepheshe bokuphrinta be-XNUMXD busathuthukiswa. Ikakhulukazi, izindlela zokunyathelisa ze-inkjet XNUMXD zinesithakazelo esikhethekile embonini yezemithi ngoba zinokufana okuningi nezinqubo zamanje zokukhiqiza futhi zinganikeza izixazululo ezisebenza kahle nezesikhathi eside zokuphrinta.

Kodwa-ke, ngenxa yokuthi imakethe yokuphrinta ye-3D isesimeni esikhulayo, kusenezithiyo ezithile ekuthuthukisweni kobuchwepheshe bokuphrinta be-3D. Ukwengeza, ukuze kuhlanganiswe kangcono izinguquko zesakhiwo sama-polymers nokuphepha kwesiguli, izinkampani ezifanele zidinga ukwenza ucwaningo olwengeziwe, futhi imboni nayo idinga ukwenza izindinganiso ezengeziwe, imininingwane kanye nemithethonqubo.
