3D kudhindwa kwemicheka yemukati, kusanganisira cornea, mitsipa yeropa uye ganda, harisi basa riri nyore. Asi zvirinani ndezvese zvipfeko zvipenyu. Pfupa, pane zvinopesana, musanganiswa wehupenyu hwepamoyo uye inorganic makomputa mune yakarongedzwa zvakanyanya mineral matrix. Mune mamwe mazwi, iyo pfupa rekudhinda 3D ibasa rakaoma.
Ndokusaka mainjiniya-mainjiniya akaedza zvinhu zvakawanda zvakasiyana pamapfupa avo echiSynthetic, kusanganisira hydrogels, thermoplastics uye biochoramcs. Nguva pfupi yadarika, timu yeYunivhesiti yeNew South Wales (Australia) yakagadziridzwa "yekudhinda panguva yekamuri tembiricha uye tishandisirwe zvakanyanya nemamiriro ezvinhu akaomarara achienzaniswa neyakaenzana tekinoroji . Maererano nevanoongorora, tekinoroji nyowani iri mumugumo inogona kujairwa kuprinta mapfupa zvakananga mumuviri wemurwere.
Ruzivo pamusoro pekukura uku rwakabudiswa mumagazini yeAdvanced Information.
3D-kudhinda kweBone Tishu kune zvakawanda zvekurapa uye zvekutsvaga zvezvirwere zvepfupa, zvinodhaka zvezvinodhaka, kudzidza kwezvinhu zvakasarudzika kudzoreredza mapfupa akakanganisika kana paine kukuvara, kana hosha kana zvimwe zvirwere.
Mhando yeGoridhe yeGoridhe yekugadzirisa mari ndeyekushandisa kwepfupa kubva kune imwe chikamu chemuviri wemurwere. Nehurombo, kushandiswa kwemakwenzi akadai kunosanganiswa nenjodzi yakanyanya yehutachiona uye haigone kushandiswa kana huwandu hunodiwa hwemafupa akakura kwazvo.
Mukuedza kugadzira iyo inodiwa yeSynthetic pfupa rezvinyorwa, yunivhesiti yakati rebhii, iyo inogona kudhindwa munzvimbo yemumvura, senge muviri. Mushure memakore maviri ebasa, ivo vakagadzira zvinhu zvevhu biocompable zvichienderana neCalcium phosphate, izvo zvinoumba pasita pamhepo tembiricha. Paunoiswa muGelatin Bath kana imwe mhinduro, maitiro emakemikari anoitika, uye iyo nzira yekushomeka muiyo pous nanocrystalline matrix, yakafanana nechimiro cheiyo yekutanga pfupa.
Zvekudhinda, ivo vaishandisa iyo standard 3D injini HR 3D Zvidiki zvidiki zvinobva ku0,2 kusvika 0.8 mm akawedzera ink mu gelatin yekugezera ne tembiricha ye37ºc. Iyo tekinoroji inonzi cobics (ceramic Omnidirectional Biokiting muCell-Smarning) inogona kugadziridzwa kune mamwe mimwe manhamba 3D maprinari, akadai manyoro ekudhinda anogona kutorwa newe mukamuri yekuvhiya.
Mubasa rake razvino, masayendisiti akadhindisa zvivakwa zvidiki zvepfupa muGelatin Bath ane masero emapfupa emapfupa uye mamwe marudzi emasero evanhu. Iyo Inosimbisa Ink yakaunzwa masero mupenyu mugwara, uye masero aya akasvika mushure mekudhinda uye akatanga kuwedzera. Kupona kwekushanda kwaive 95%.
Parizvino, timu inokudziridza yekugeza yekudhinda samples hombe uye yakatanga kuitisa kuongororwa pazvipfuyo zvidiki kuti vatarise kana iyi tekinoroji inogona kudzorera ronda rakakura sekusapurirana.
