Ithimba lososayensi e-Massachusetts Institute of Technology kanye naseStevens Institute of Technology eNew Jersey lidale ubuchwepheshe bokuphrinta be-3D obunokulungiswa okuphezulu kakhulu. Amaphrinta avamile e-3D angaphrinta ama-elementi amancane njengama-microns angu-150. Ubuchwepheshe obuhlongozwa e-MIT buyakwazi ukuphrinta isici esingu-10 microns. Ukunemba okunjalo akudingekile ukuze kusetshenziswe kabanzi ekunyatheliseni kwe-3D, kodwa kuzoba usizo kakhulu ocwaningweni lwe-biomedical kanye nezokwelapha futhi kuthembise ngisho nokuphumelela kulezi zindawo.
Iqiniso liwukuthi namuhla, uma kuqhathaniswa, ama-substrates anezinhlangothi ezimbili asetshenziselwa ukukhulisa amasiko amaseli. Ukuthi ama-cell colonies akhula kanjani futhi kanjani ku-substrates enjalo kuyindaba yenhlanhla. Ngaphansi kwezimo ezinjalo, akunakwenzeka ukulawula ngokunembile ukuma nobukhulu bekoloni enwetshiwe. Enye into yindlela entsha yokukhiqiza i-substrate substrate. Ukwandisa ukulungiswa kokuphrinta kwe-3D esikalini seseli kuvula indlela eya ekudalweni kwesakhiwo seselula esivamile noma esinezimbotshana, ukuma okuzocacisa ngokunembile ubukhulu nokubukeka kwekholoni yeseli yesikhathi esizayo. Futhi ukulawula ifomu kuzonquma kakhulu izakhiwo zamaseli kanye nekoloni lilonke. Kuthiwani ngamakoloni? Uma wenza i-substrate ngesimo senhliziyo, kuzokhula isitho esibukeka njengenhliziyo, hhayi isibindi.
Ake senze ukubhuka ukuthi okwamanje asikhulumi ngezitho ezikhulayo, nakuba abacwaningi bephawula ukuthi ama-stem cells aphila isikhathi eside kuma-substrates enziwe ngamangqamuzana angama-micrometer kunaku-substrate evamile. Ukuziphatha kwamakholomu amaseli anezakhiwo ezihlukene ku-substrate entsha enezinhlangothi ezintathu kuyacwaningwa okwamanje. Ukuqaphela kubonisa ukuthi ama-molecule amaprotheni amangqamuzana adala ukunamathela okuthembekile okugxile endaweni yokunamathela ku-substrate lattice nakwamanye, okuqinisekisa ukukhula kwekholoni kumthamo wemodeli ye-substrate.
Ososayensi bakwazi kanjani ukwandisa ukulungiswa kokuphrinta kwe-3D? Njengoba kubikiwe esihlokweni sesayensi kumagazini i-Microsystems kanye ne-Nanoengineering, ubuchwepheshe bokuncibilika kwe-electrowriting busize ukwandisa ukulungiswa. Empeleni, kwasetshenziswa inkambu eqinile kazibuthe kagesi phakathi kwekhanda lokuphrinta lephrinta ye-3D kanye ne-substrate yokuphrinta imodeli, eyasiza ukuchoboza futhi ngendlela ethile ukuqondisa okuncibilikisiwe okuphuma emibhobho yekhanda lokuphrinta. Ngeshwa, ayikho eminye imininingwane enikeziwe.
