Ochita kafukufuku apanga njira yapadera yosindikizira ya 3D yomwe ingachepetse ndalama ndi zowonongeka

Kusindikiza kwa 3D kukusintha kamangidwe kazinthu ndi kupanga m'malo ambiri: kuchokera kuzinthu zopangidwa ndi anthu ogula kupita kuzinthu zamano zosindikizidwa za 3D ndi mafupa opulumutsa moyo ndi implants zachipatala. nthawi yayitali, zomwe zimapangitsa kuti zikhale zovuta kugwiritsa ntchito kusindikiza kwa 3D pamlingo waukulu.

 

 

Nthawi iliyonse chosindikizira cha 3D chimapanga chinthu chokhazikika, makamaka chokhala ndi mawonekedwe apadera, chimafunanso chithandizo chosindikizira, chosindikizira chomwe chimathandiza kusunga umphumphu wa mawonekedwe ake mwa kulinganiza chinthu monga chosindikizira chimachipanga chosanjikiza ndi chosanjikiza. zothandizira ziyenera kuchotsedwa pamanja pambuyo pa kusindikiza, zomwe ziyenera kuchitidwa ndi manja ndipo zingayambitse mawonekedwe olakwika kapena roughness pamwamba.Zinthu zomwe zimagwiritsidwa ntchito popanga scaffolds nthawi zambiri sizingagwiritsidwe ntchito, choncho zimatayidwa, zomwe zimapangitsa kuti pakhale kusindikiza kwa 3D. zinyalala vuto.

Malo atsopano owongolera osindikizira a 3D (kumanzere) achepetsa kufunika kothandizira kusindikiza (pakati), kuchepetsa kuwononga komanso kusunga nthawi.

 

 

Kwa nthawi yoyamba, ofufuza a Daniel J. Epstein dipatimenti ya Industrial and Systems Engineering ku yunivesite ya Southern California ku Viterbi apanga njira yotsika mtengo, yothandizanso kuti achepetse zothandizira zosindikizira zosindikizira za 3D, kuwongolera kwambiri mtengo- mphamvu ndi kukhazikika kwa kusindikiza kwa 3D.

 

 

Kafukufukuyu, motsogozedwa ndi Yong Chen, pulofesa wa engineering and systems engineering, ndi Yang Xu, wophunzira wa PhD, adasindikizidwa mu Additive Manufacturing.

 

 

Kusindikiza kwachikhalidwe kwa 3D kumagwiritsa ntchito ukadaulo wosungunula (FDM) kusindikiza zigawo molunjika pazitsulo zosasunthika. M'malo mosindikiza mabaketi, mawonekedwe atsopanowa amagwiritsa ntchito malo osinthika, oyendetsedwa bwino opangidwa ndi singano zachitsulo zosunthika. , mapini amawuka.Chen adati kuyesedwa kwachitsanzo chatsopanochi kunawonetsa kuti chitha kupulumutsa pafupifupi 35 peresenti ya zida zosindikizira.

 

 

Ndimagwira ntchito ndi madokotala a zamankhwala omwe amagwiritsa ntchito biomaterials kusindikiza kwa 3D kuti apange minyewa kapena ziwalo, Chen adati, ndipo zinthu zambiri zomwe amagwiritsa ntchito ndizokwera mtengo kwambiri - tikukamba za mabotolo ang'onoang'ono omwe amawononga $ 500 mpaka $ 1,000 pa botolo.

Kwa makina osindikizira a FDM, mtengo wamtengo wapatali uli pafupi $ 50 pa kilogalamu, koma kwa bio-printing, ndizofanana ndi $ 50 pa gram.Choncho ngati tingapulumutse 30 peresenti pa zipangizo zomwe zimagwiritsidwa ntchito kusindikiza zipangizo zothandizira izi, ndiko kupulumutsa ndalama zambiri. zosindikiza za 3D pazolinga zamankhwala.

 

 

Kuphatikiza pa kuwononga chilengedwe komanso mtengo wa zinyalala zakuthupi, njira yachikhalidwe yosindikizira ya 3D pogwiritsa ntchito scaffolds imatenganso nthawi, adatero Chen.

 

 

Mukakhala mawonekedwe osindikizira a 3D ovuta, theka la nthawi likumanga magawo omwe mukufuna ndipo theka lina likumanga chithandizo.Mu dongosolo lino, sitiyenera kumanga chithandizo.Chotsatira chake, tinapulumutsa pafupifupi 40 peresenti mu mawu a nthawi yosindikiza.

 

 

Ma prototypes ofanana omwe adapangidwa m'mbuyomu adadalira injini imodzi kuti ithandizire mabatani aliwonse amakina, zomwe zimapangitsa kuti pakhale kugwiritsa ntchito mphamvu zambiri komanso zinthu zodula kwambiri, zomwe zimapangitsa kuti zikhale zopanda ndalama kwa osindikiza a 3D, adatero Chen.

 

 

Kotero, ngati muli ndi mapini 100 osuntha omwe amawononga pafupifupi $ 10 pa galimoto, ndiye kuti zonsezo ndi $ 1,000, kuphatikizapo 25 control panels kuti muzitha kuyendetsa magalimoto osiyanasiyana a 100. Chinthu chonsecho chidzawononga ndalama zoposa $ 10,000.

 

 

Chitsanzo chatsopano cha gululi chimagwiritsa ntchito injini imodzi kuyendetsa chithandizo chilichonse kuti chisunthire nsanja.Pulatifomu imakweza mapepala angapo azitsulo panthawi imodzi, yomwe ndi njira yotsika mtengo.Malinga ndi kapangidwe kazinthu, pulogalamu ya pulogalamuyo imauza ogwiritsa ntchito kuti ayenera onjezerani machubu achitsulo pansi pa nsanja.Malo a machubuwa adzatsimikizira kuti ndi zikhomo ziti zomwe zidzakwezedwe kufika pamtunda wotchulidwa kuti zithandizire bwino chosindikizira cha 3D komanso kupanga kutaya kochepa kwa chithandizo chosindikizira.Pamapeto a ndondomekoyi, zikhomo akhoza kuchotsedwa mosavuta popanda kuwononga mankhwala.

 

 

Chen adati dongosololi litha kusinthidwanso mosavuta popanga anthu ambiri, monga mafakitale agalimoto, ndege ndi ma yacht.

 

 

Makina osindikizira a FDM akupangidwira kale magalimoto akuluakulu ndi ma fuselages ndi katundu wogula monga mipando. Monga momwe mungaganizire, amatenga nthawi yaitali kuti amange, tikulankhula tsiku lonse. Kotero ngati mungathe kudula pakati, nthawi yopanga imatha kutsika mpaka theka la tsiku.Pali zopindulitsa zambiri pakusindikiza kwa 3D uku pogwiritsa ntchito njira yathu.

 

 

Gululi linafunsiranso posachedwa patent yaukadaulo watsopano, Chen adati.Phunziroli linalembedwa ndi Ziqi Wang, wophunzira wochezera ku EPFL School of Computer and Communication Sciences ku Switzerland, ndi Siyu Gong, wochokera ku Viterbi.
