Ukuphrinta kwe-3D, ikakhulukazi ubuchwepheshe obuningi obungakunikeza emkhakheni wezokwelapha, kukhula ngokweqile, ubufakazi balokho engikushoyo ukuthi unakho kanjani, kuze kube yiminyaka embalwa edlule into efana nalokhu engifuna ukukutshela namhlanje bekungacabangi ngokoqobo, a inhliziyo eyenziwe ukuphrinta kwe-3D, eyenziwe iqembu labacwaningi abavela ku- I-ETH Zurich University (Switzerland), ekwazi ukusebenza isikhathi esiyimizuzu engama-30 kuye kwengama-40.
Ngokuqondene nenhliziyo ongayibona esibukweni, kufanele kuqashelwe ukuthi kuyimodeli, njengoba ungaqagela, ine usayizi ofanayo nenhliziyo yomuntu futhi a isisindo esifanayo, Amagremu angama-390. Ukuze kwenziwe, njengoba kuvezwe yithimba labaphenyi, kusetshenziswe inqubo elahlekile yokuphonsa i-wax.
Le phrojekthi evela e-ETH University of Zurich ikwazile ukukhombisa ukuthi, ngokusebenzisa ukuphrinta kwe-3D, izitho ezinjengezinhliziyo ezisebenza ngokugcwele zingakhiwa.
Ngamazwi ka UNicholas cohrs, umfundi odokotela e-ETH Zurich:
Lokhu bekumane kuwukuhlolwa kokungenzeka. Inhloso yethu bekungekona ukwethula inhliziyo elungele ukufakwa, kepha ukucabanga ngomkhondo omusha wokuthuthuka kwezinhliziyo zokufakelwa.
Njengemininingwane yokugcina, yazi ukuthi le nhliziyo, njengesibonelo sangempela ngokuphelele, ine-ventricle yangakwesokudla nangakwesobunxele ehlukaniswe yikamelo esebenza njengesicubu somzimba. Ukusebenza kwayo kulula njengokuthi, lapho igumbi ligcwala futhi lihluthwa ngumoya ocindezelweyo, liyakwazi ukukhipha uketshezi ngaphandle kwamagumbi. Uma udinga imininingwane eyengeziwe, ngaphandle kokungabaza ividiyo elungile ekuqaleni kokungena okunwetshiwe ingaba usizo olukhethekile ukukuqonda konke lokhu.
