Ziningi izikhungo ezizama ukuthuthukisa ukuphrinta kwe-3D ukuze ikwazi ukushesha, inekhono futhi inentshisekelo ikakhulukazi uma kukhulunywa ngokufakwa kuwo wonke amaketanga okukhiqiza emhlabeni. Kulesi senzakalo ngifuna ukukutshela ngomsebenzi owenziwe iqembu labacwaningi abavela ku Inyuvesi yaseFlorida abakwazile ukusungula indlela entsha ye ukuphrinta okungamanzi abicah 3D.
Njengoba bephawule ephepheni elishicilelwe mayelana nephrojekthi, phakathi kwezinzuzo ezinkulu ezitholakala kule phrojekthi, ukugqamisa, ngokwesibonelo, ukuthi ngenxa yokusetshenziswa kokuphrintwa kwe-3D kwe-liquid silicone kuzokwazi thuthukisa anhlobonhlobo amadivayisi wezokwelapha kanye nokusheshisa ukufakwa kwayo ekwelashweni nasekusebenzeni njengamapayipi oketshezi lomzimba, amabhaluni, ama-catheters athambile, amabhande okutshala, amasilingi nezindwangu.
Uphenyo lwe IYunivesithi yaseFlorida iholela ekwakhiweni kwendlela yokwenza umbono wezokwelapha abicah.
Ukungena emininingwaneni ethe xaxa, sifunda ukuthi le ndlela entsha isebenzisa inqubo ebonakalayo ye 'ukuphazamiseka'lapho i-viscosity yezinto ezibonakalayo ikhula njengoba ubukhulu bezinhlayiya bukhuphuka. Lokhu kuvumela ukwenziwa kwamadivayisi athile ezokwelapha lokho bangakhukhumala futhi bavumelane ngokuya ngezenzo ezithile ezenziwe.
Into ethakazelisa kakhulu ngale phrojekthi ukuthi yavela kolunye ucwaningo olumayelana nokukopisha. Ngenxa yentuthuko yayo, le ndlela entsha yokuphrinta izinto ezithambile yatholakala izisebenzisa izinhlayiya ezincane ze-hydrogel ezinezinki 'okunamafutha' ezifana abicah.
Njengoba kuphawuliwe UChristopher O'Bryan, Umfundi we-PhD wobunjiniyela bemishini ne-aerospace eHerbert Wertheim College ye-UF of Engineering:
Izinto zethu ezintsha zihlinzeka ngokusekelwa kwe-liquid silicone ekuphrintweni kwe-3D, okusivumela ukuthi sakhe izakhiwo eziyinkimbinkimbi kakhulu futhi nezingxenye ezifakwe ku-silicone elastomer.
Lapho sesiqale ukuphrinta ama-oyili abicah abicah ezintweni ezinamafutha ze-microgel, izingxenye eziphrintiwe zagcina ukwakheka kwazo. Sikwazile ukufeza izingxenye ezinhle impela sisebenzisa ukuphrinta kwe-silicone 3D, okungcono kakhulu engikubonile.
