Kudhinda kwe 3D kuri kushandura kugadzirwa kwechigadzirwa nekugadzira munzvimbo dzakawanda: kubva kune zvakagadzirirwa-zvakagadzirwa zvikamu zvezvigadzirwa zvevatengi kune 3D-yakadhindwa yemazino zvigadzirwa uye inoponesa hupenyu bhonzo uye yekurapa implants.Zvisinei, iyo nzira inogadzirawo yakawanda inodhura uye isingagoneki tsvina uye inotora. nguva refu, izvo zvinoita kuti zviome kushandisa 3D kudhinda pamwero mukuru.
Nguva imwe neimwe printer ye 3D inobudisa chinhu chetsika, kunyanya chimwe chine chimiro chakakosha, inodawo tsigiro yekudhinda, chibatiso chekudhinda chinobatsira kuchengetedza kutendeseka kwechimiro chayo nekuenzanisa chinhu sezvo printer inogadzira iyo layer by layer.Zvisinei, izvi zvitsigiro zvinofanira kubviswa nemaoko mushure mekudhinda, izvo zvinoda kuitwa nemaoko uye zvinogona kutungamirira kune chimiro chisina kururama kana kuoma kwepamusoro.Zvinhu zvinoshandiswa kugadzira scaffolds kazhinji hazvigoni kushandiswa zvakare, saka zvinorasirwa kure, zvichiita kuti pave nekukura kwe 3D kudhinda. dambudziko remarara.
A new dynamic control base for 3D printing (kuruboshwe) inoderedza kudiwa kwetsigiro yekudhinda (pakati), kuderedza kutambisa uye kuchengetedza nguva.
Kekutanga, vatsvakurudzi paDaniel J. Epstein Dhipatimendi reMaindasitiri neSystems Engineering paYunivhesiti yeSouthern California kuViterbi vakagadzira nzira yakaderera, inogona kushandiswazve yekutsigira kuderedza izvi zvinoparadza 3D printer printing inotsigira, kuvandudza zvikuru mutengo- kushanda uye kusimba kwe 3D kudhinda.
Tsvagiridzo, inotungamirwa naYong Chen, purofesa weinjiniya uye masisitimu einjiniya, uye Yang Xu, mudzidzi wePhD, yakaburitswa muAdditive Manufacturing.
Kudhinda kwechinyakare kwe3D kunoshandisa tekinoroji yekunyungudutsa deposition modeling (FDM) kudhinda zvidimbu zvakananga panzvimbo yesimbi isingachinjiki.Pachinzvimbo chekudhinda mabhuraketi, prototype itsva inoshandisa nzvimbo inorongeka, inodzorwa zvine simba yakagadzirwa netsono dzesimbi dzinofambiswa.Sezvo printer inovaka chigadzirwa nhanho nhanho. , mapini anosimuka.Chen akati bvunzo dzechigadzirwa chitsva ichi dzakaratidza kuti inogona kuchengetedza zvikamu makumi matatu neshanu kubva muzana zvemidziyo yekudhinda.
Ndinoshanda nevarapi vebiomedical avo vanoshandisa biomaterials kudhinda 3D kuvaka matishu kana nhengo, Chen akadaro, uye zvinhu zvakawanda zvavanoshandisa zvinodhura zvakanyanya - tiri kutaura nezvemabhodhoro madiki anodhura $500 kusvika $1,000 pabhodhoro.
Kuprinta yeFDM yakajairwa, mutengo wezvinhu unosvika madhora makumi mashanu pakirogiramu, asi kudhinda kwebio, inofanana nemadhora makumi mashanu pagiramu.Saka kana tikakwanisa kuchengetedza zvikamu makumi matatu kubva muzana pazvinhu zvakashandiswa kudhinda zvinhu zvekutsigira izvi, imari yakawanda yekuchengetedza. ye 3D kudhinda kune biomedical zvinangwa.
Pamusoro pezvakatipoteredza uye mutengo wemararamiro emarara, iyo yechinyakare 3D yekudhinda maitiro uchishandisa scaffolds zvakare inotora nguva, Chen akadaro.
Kana iwe uri 3D kudhinda kwakaoma maumbirwo, hafu yenguva iri kuvaka zvikamu zvaunoda uye imwe hafu iri kuvaka tsigiro.Muhurongwa uhu, hatifanirwe kuvaka rutsigiro.Nekuda kweizvozvo, takachengeta ingangoita 40 muzana mu. nguva yekudhinda.
Maprototypes akafanana akagadzirwa munguva yakapfuura aivimba nemota imwe chete kutsigira yega mekiniki bracket, zvichikonzera kushandiswa kwesimba kwakanyanya uye chigadzirwa chinodhura zvakanyanya, zvichiita kuti ive isina hupfumi kune vanodhinda 3D, Chen akadaro.
Saka, kana uine 100 mapini ekufambisa anodhura anenge $ 10 pamotokari, zvino iyo yose i $ 1,000, pamwe ne 25 control panels kudzora 100 yakasiyana-siyana. Chinhu chose chichadhura kudarika $ 10,000.
Chiratidziro chitsva chechikwata chinoshandisa mota imwe chete kutyaira chitsigiro chega chega kufambisa chikuva.Chikuva chinosimudza seti dzakawanda dzepini dzesimbi panguva imwe chete, inova mhinduro isingadhuri.Maererano nekugadzirwa kwechigadzirwa, software yechirongwa inoudza vashandisi kuti vanofanirwa wedzera nhevedzano yemachubhu esimbi kuzasi kwepuratifomu.Mamiriro emachubhu aya ndiwo acharatidza kuti mapini achasimudzwa kusvika paurefu hwakatarwa kuti atsigire zvakanakisa chigadzirwa chakadhindwa che 3D ukuwo uchigadzira kurasikirwa kudiki kwerutsigiro rwekudhinda.Pakupera kwe nzira iyi, mapini anogona kubviswa nyore pasina kukuvadza chigadzirwa.
Chen akati sisitimu iyi inogona zvakare kuchinjirwa zviri nyore kugadzira ruzhinji, senge mota, aerospace uye maindasitiri eyacht.
FDM maprinta ari kutogadzirwa emota hombe nengarava fuselage uye zvinhu zvevatengi zvakaita sefenicha.Sezvaungafungidzira, zvinotora nguva yakareba chaizvo kuvaka, tiri kutaura zuva rose.Saka kana iwe uchigona kucheka nepakati, yako nguva yekugadzira inogona kudzika kusvika hafu yezuva.Kune zvakawanda zvinobatsira kune iyi 3D kudhinda tichishandisa nzira yedu.
Dare racho rakanyorerawo munguva pfupi yapfuura patent ye teknolojia itsva, Chen akati.Chidzidzo chacho chakabatanidzwa naZiqi Wang, mudzidzi anoshanyira paEPFL School of Computer and Communication Sciences muSwitzerland, uye Siyu Gong, kubva kuViterbi.
