UmbonoTEC ubelokhu esematheni muva nje ngemuva kokwethulwa kwezinto ezintsha ezingekho ngaphansi kwezingu-7 ezinikezelwe ngokukhethekile ukuthi zisetshenziswe ekuphrinteni kwe-3D, izinto, ngokwesiko kuhlobo lwazo, ezingasetshenziswa kuphela yizinhlobo ezenziwe yinkampani .
Ngokuya ngokuningiliziwe, sithola izinto ezi-3 ezintsha ezikhethekile zamaphrinta ohlobo ugqoko photopolymerization ngenkathi ezine ezisele zenzelwe ukuthi zisetshenziswe yi 3D bioprinters kusuka ku-EnvisionTEC. Ukwethulwa kwalezi zinto ezintsha kwenzeke kusetshenziswa umbukiso we-RAPID + TCT obanjwe kulezi zinsuku edolobheni lasePittsburgh, e-United States.
I-EnvisionTEC iveza kuze kufike kuzinto eziyisikhombisa ezintsha ezikhethekile zamaphrinta ayo e-7D.
Ngokuya ngezitatimende ezenziwe ngu- Al-Siblani, Isikhulu Esiphezulu se-EnvisionTEC:
Lo mnikelo omusha ukhombisa ukuzibophezela kwethu ekuthuthukiseni izinto zokwakha, kanye nobudlelwano obuseduze namakhasimende ethu, asicele ukuthi sakhe izinto ezithile zemishini yethu ethembekile neqondile.
Phakathi kwezinto eziyisikhombisa ezintsha sithola imikhiqizo yazo zonke izinhlobo zokusetshenziswa njenge:
- I-E-CE, into eqinile, yokushisa neyamakhemikhali enokuqhathaniswa nezinye izinto ezisuselwa ku-cyanate. Ngokuphambuka okushisayo okungafika ku-170 ºC, kukhonjiswa ezimeni lapho kudingeka khona ukuzinza okushisayo.
- I-Epoxy, okokusebenza okufakwa ama-biomaterials nokwelashwa okuphindwe kabili, okuvumela ukwenza izingcezu ezingazweli ngisho nezindonga ezincane. Baqokomisa ubudlelwano obuhle phakathi kokuguquguquka, ubulukhuni nokumelana okushisayo.
- I-E-Model Flex Ngakolunye uhlangothi, kungumbhalo wokumodela oqondile, ngokunwebeka kuze kube ngcono ngekhefu, uzonikezwa ngemibala ephuzi noluhlaza.
- I-Silicon TG, i-silicone yezobuchwepheshe yokwenza amamodeli wokuhlinzwa athambile, njengekhala noma amabele. Ukwelapha akudingi ukwenziwa kusebenze, okwenzeka emahoreni ambalwa ngokuncipha okuncane kakhulu.
- I-PCL 45K RG, ibanga locwaningo i-polycaprolactone (PCL) yezicelo zobunjiniyela bezicubu. Le PCL inikela ngozinzo lokukhanda ngokulawula i-porosity yocezu, ilungele ukusetshenziswa ekuvuseleleni amathambo noqwanga, kanye nokuvumela ukukhishwa kwezidakamizwa ngesikhathi senqubo ye-bioabsorption, elinganiselwa phakathi konyaka owodwa kuya kwemithathu.
- Ukusekelwa kwe-LT RG, okokusebenza kwe-saccharide okususelwe kuselulose, okusetshenziselwa izisekeli ezisusekayo. Ingacutshungulwa njenge-hydrogel bese ichitheka emanzini acwecwe. Iyahambisana futhi ayithinti izakhiwo zebhayoloji zengcezu yokugcina. Le nto inezinga lokushisa elisetshenziswa ngama-23 ºC.
- Ukusekelwa kwe-HT RG, kungenye impahla yokusekela emazingeni aphezulu okushisa, isebenza ku-150 ºC. Kutholakala ngoshukela futhi kuyancibilika emanzini acolisisiwe ekamelweni lokushisa emaminithini ambalwa.
