Mazuva ano, 3D maprinta anoshandiswa kugadzira ese marudzi ematoyi uye doodads. 3D-yakadhindwa zvishongo uye zvimwe fashoni zvinhu zvava kupisa inopisa maitiro. Zvese izvi zvinonakidza uye zvine hunyanzvi, asi zvakadiniko kana tekinoroji ichigona kushandiswa zvakanyanya? Iko mukana kuri kungoongororwa chidimbu chezvavangave zviri munguva pfupi iri kutevera. Sayenzi yave padhuze nekutsvaga nzira dzekutenderera nekushomeka kwenhengo dzinowanikwa pakuisa uye kumisikidza. Kunyangwe pave paine bioprinters munguva yakapfuura, matambudziko mazhinji anoramba aripo. Kusakwanisa kuchengetedza maseru ari mupenyu kwenguva yakareba zvakakwana kuti aapfekedze kwakatadzisa kufambira mberi kwechirevo.
Pinda iyo 3D printa
Parizvino, kufambira mberi kwekurapa kunosanganisira 3D-yakadhindwa nhengo dzakaita semwoyo yekugadzira, nzeve, uye kunyange mapfupa emapfupa. Saka kuregererei mativi emaziso? Kune mamiriyoni evanhu pasi rose vari kutambura nekutadza kuona kunokonzerwa nezvirwere zvine chekuita nemaziso. Nyika dzine hurombo dzinowanzova nehutachiona hunokonzera kukuvara kwecornea, uye kana husina kurapwa, upofu. Tinogona here kushandisa tekinoroji inopihwa ne3D kudhinda kugadzira replica corneas? Mukana wekuti izvi zviitike nekukurumidza kupfuura gare gare wakakwira. Iyi mhando yeprinta inoda inki nyaya kuti ishande. Parizvino, vaongorori vari kusanganisa alginate (gelling agent yakatorwa kubva marinewe) ine collagen mapuroteni kugadzira bio-inki. Ingi inoda kuve 'mhenyu' kuti isanganise nemasero emunhu. Zvaizoda kubvumidza matishu anobatanidza kuwanda kuti muviri wemunhu ugamuchire uye ubatanidze zvinhu zveprosthetic. Masero anoita senge mhinduro ine chekuita nekugadzira iyi mhando yezvinhu 'yekurarama'.
Kuwedzera kwema cell kwatoratidzwa mune mamwe marudzi eprosthetics. Nekudaro, pasina gadziriro yeropa isingachinji, aya maseru anogona kungorarama yakaganhurirwa yenguva. Vatsvagiri vari kutsvaga nzira dzekuti vaone hupenyu hwemaseru kuburikidza nekudhinda uyezve zvimwe. Parizvino, iwo bio gels uye ekutsiva 'zvikamu' zvakaratidza inoshamisa nzira yekugadzira yakasarudzika chassis. Maseru mapenyu mune ino chassis anotanga kuumba yavo yega bio 'mesh' uye vanozvibata pamwechete. Nekufamba kwenguva, iyo yekugadzira nyaya (kazhinji mafomu esilicone uye ekurapa giredhi repurasitiki) inodzima kana kuparara, ichisiya chete yehupenyu chinhu munzvimbo yayo. Kunyangwe iyo 3D-yakadhindwa chinhu inopa iyo yekutanga dhizaini yekuisirwa, maseru pachawo anoumba rudzi rwematrix anokwanisa kuchengetedza chimiro chayo.
Zvakare zvinonakidza: Amai, Ndinogona Kuva Cyborg?
3D-kudhinda corneas yevanhu
Nyowani nyowani kana kunyange shwashwa uye bone maseru chizvarwa chinogona kuzopedzisira chateedzera zvakasara zvemuviri wemunhu. Mukuyedzwa nemakonzo emumabara, zvimedu zvedehenya zvakasimwa zvakaratidza kuti vaikwanisa kumera nyama yavo yemabhonzo, izere neropa. Uye ne3D-yakadhindwa tsandanyama implants, mbeva dzakagadzira tsinga dzemasuru. Uku kukura kutsva kwakangotora mavhiki maviri kuti aumbe. Kunyangwe bvunzo dzichiri kufanira kuitiswa pazvidzidzo zvevanhu, zvinoratidza mukana wekuita kudaro nekumwe kutsvagurudza.
Corneal implants yaizoshanda nenzira imwechete. Asi ko mhasuru kana yakasimba pfupa raizove nyore kuumbika kupfuura zvinyama zvinoda 'kuona'? Chimiro chemaziso hachifanirwe kwete kungofamba uye kuchengetedza chimiro asi zvakare kubatsira munhu kuti aone. Ko huropi hungabatanidzazve kune iyo corneal implant kuti ipe inoshanda kuona? Kana mainjiniya akakwanisa kudhinda inki yekudhinda ye3D, zvinyama zvekubereka zvingangokwanisa 'kuzvifunga' nerubatsiro rwehuropi hwemunhu. Zvakawanda munzira iyo cochlear inodyara (chishandiso chakavharirwa kuseri kwenzeve kubatsira kurasikirwa kwekunzwa uye matsi) inodzidza kubatana zvakare kuhuropi kududzira ruzha, chimiro cheziso chingangokwanisa kuita zvakafanana.
Munguva pfupi, 3D-yakadhindwa corneas inogona kugadzirisa dambudziko rekumirira anoenderana munhu mupi. Kubva pakombuta kusvika pakudhinda kamwene kuziso, sainzi iri kugadzira mhinduro dzekurapa isu taingofunga kuti zvinogoneka musainzi-ngano mafirimu. Zvichatora nguva yakareba sei kusvika pakunzi cyborgs famba pakati pedu? Inguva chete ndiyo ichaudza.
