Chikwata chemasayendisiti kuMassachusetts Institute of Technology uye Stevens Institute of Technology muNew Jersey yakagadzira yakanyanya-resolution 3D yekudhinda tekinoroji. Zvekare 3D maprinta anogona kudhinda zvinhu zvidiki se150 microns. Tekinoroji yakatsanangurwa kuMIT inokwanisa kudhinda chinhu 10 microns gobvu. Kunyatsorongeka kwakadaro hakudiwi pakushandiswa kwakapararira mukudhinda kwe3D, asi kuchabatsira zvakanyanya kutsvagurudzo yebiomedical neyekurapa uye inovimbisa budiriro munzvimbo idzi.
Icho chokwadi ndechekuti nhasi, tichitaura, maviri-dimensional substrates anoshandiswa kukura sero tsika. Maitiro uye sei maseru colonies anokura pane akadaro substrates inyaya yemukana. Pasi pemamiriro ezvinhu akadaro, hazvibviri kunyatso kudzora chimiro uye ukuru hwekoroni yakawedzerwa. Chimwe chinhu inzira nyowani yekugadzira iyo substrate substrate. Kuwedzera kugadziriswa kwe 3D kudhinda kune sero chiyero kunovhura nzira yekusikwa kweiyo yenguva dzose cellular kana porous chimiro, chimiro chayo chinozonyatso tsanangura ukuru uye kutaridzika kweramangwana sero colony. Uye kudzora chimiro kunozonyanya kuona zvimiro zvemasero uye koloni zvachose. Zvakadini nemakoloni? Kana iwe ukaita substrate muchimiro chemoyo, nhengo inokura inoita semoyo, kwete chiropa.
Ngatitorei chengetedzo kuti parizvino hatisi kutaura nezve nhengo dzinokura, kunyangwe vaongorori vachiona kuti stem masero anorarama kwenguva yakareba pane substrates dzakagadzirwa ne micrometer-saizi maseru pane pane yakajairwa substrate. Maitiro emakoloni emaseru ane zvimiro zvakasiyana pane itsva-dimensional substrate ari kudzidzwa parizvino. Ongororo dzinoratidza kuti mapuroteni mamorekuru emasero anogadzira akavimbika anonamira padanho rekunamatira kune substrate lattice uye kune mumwe nemumwe, kuve nechokwadi chekukura kwekoloni muhuwandu hweiyo substrate modhi.
Masayendisiti akakwanisa sei kuwedzera kugadzirisa kwe 3D kudhinda? Sezvakataurwa muchinyorwa chesainzi mujenari Microsystems uye Nanoengineering, kunyungudutsa tekinoroji yemagetsi yakabatsira kuwedzera kugadzirisa. Mukuita, simba remagetsi remagetsi rakaiswa pakati pemusoro wakadhindwa weprinta ye3D uye substrate yekudhinda modhi, iyo yakabatsira kupwanya uye neimwe nzira kutungamira iyo yakanyungudutswa ichibuda kubva mumusoro weprint nozzles. Sezvineiwo, hapana zvimwe zvinopihwa.
