Ubuchwepheshe obusha bokuphrinta be-3D buyathuthukiswa ngesivinini esikhulu kangangokuthi kulula ukucabanga ngekusasa eliseduze lapho kungekho lutho olungakwazi ukuphrintwa nge-3D.
Ububanzi bezinto ezitholakalayo bungenye yezithiyo ezibalulekile zokwamukelwa kokuphrinta kwe-3D yezimboni.Ukuphrinta kwe-3D kwamukelwa ngokushesha abakhiqizi bemikhiqizo emhlabeni wonke, kodwa namanje akukwazi ukuncintisana namanye amasu okukhiqiza amaningi ngokuphathelene nokuhlukahluka kwempahla.Inombolo enkulu yamapulasitiki ezimboni asetshenziswa kakhulu ayikatholakali kabanzi kumaphrinta e-3D, okwenza ukuphrinta kwe-3D kungafaneleki ezinhlelweni zokusebenza eziningi.
I-PTFE (i-polytetrafluoroethylene) iyimpahla ewusizo kakhulu, esetshenziswa emikhiqizweni eminingi yansuku zonke.I-hydrophobic kakhulu, okusho ukuthi akukho manzi noma izinto eziqukethe amanzi ezenza kube manzi, ngakho-ke isetshenziselwa izingubo zangaphandle.Iphinde ibe neyodwa yama-coefficients aphansi kakhulu wokungqubuzana kwanoma yikuphi okuqinile.Iwukuphela kwendawo isigcilikisha esingakwazi ukunamathela kuso.Lesi sakhiwo siyenza ifanelekele ukunamathela okungagxili kwe-bakeware.Amagciwane kanye namanye amagciwane aphinde abe nesikhathi esinzima kakhulu sokunamathela kulokho okubalulekile, okwenza kube inketho enhle kakhulu yezicelo zesibhedlela ezahlukahlukene, njengama-catheter.
Amanye ama-fluoropolymers nawo asetshenziswa kakhulu ezimbonini zikawoyela negesi, amakhemikhali, ezezimoto kanye nezomkhathi, futhi kungenzeka ukuthi kusetshenziswe ubuchwepheshe obufanayo bokuphrinta be-3D kubo.Lokhu kuphumelela kwenza kube nokwenzeka ukuphrinta kwe-3D ikilasi elisha lezinto zokwakha, elizothonya izimboni eziningi.
Ngokuvamile, izingxenye ezenziwe nge-PTFE namanye ama-fluoropolymers akhiqizwa kusetshenziswa amasu okucubungula endabuko abizayo, ngokuvamile adala udoti omningi.Kunzima futhi ukwakha izakhiwo eziyinkimbinkimbi kakhulu.Ukuphrinta kwe-3Dinamandla okunikeza ukukhiqiza okusimeme kanye nezinhlobonhlobo ezibanzi zemiklamo.Impumelelo isivele ivula indlela yezinhlelo zokusebenza ebezingenakwenzeka ngaphambilini.
Ama-polymers ane-fluorinated, aka fluoropolymers, angase angabi bukhazikhazi njengamadayimane, kodwa ayingxenye ebalulekile ezinqubweni eziningi zokukhiqiza.Amapulasitiki asekelwe ku-fluorocarbon ahlukaniswa ngokuqina kwawo okuphezulu nokusebenza kwawo ukumelana namakhemikhali anokhahlo namazinga okushisa aphezulu.Asetshenziswa kuyo yonke into kusukela ku-aerospace nezinhlelo zokusebenza zokuvikela ukuya ezindaweni zokupheka ezinganamathiki, ama-fluoropolymer akhona yonke indawo - ngaphandle kwamaphrinta e-3D.
Lokho kungase kushintshe maduzane, njengoba inkampani yokuthuthukisa umkhiqizo i-3M ifake ilungelo lobunikazi lohlobo olusha lobuchwepheshe bokuphrinta be-3D obuzovumela ukukhiqizwa okungeziwe kwama-polymer agcwele fluorinated.Ubuchwepheshe buzosho ukuthi izakhiwo eziyinkimbinkimbi zingenziwa ngokushesha futhi ngezindleko eziphansi, kanti izingxenye ezifanayo ngokuvamile zingabiza kakhulu ukukhiqiza ngezinye izindlela zokukhiqiza.
Yize kunezinhlobo eziningi zamapholymeri ane-fluorinated, mhlawumbe leyo ezozuza kakhulu ekuphrinteni kwe-3D i-polytetrafluoroethylene noma i-PTFE, eyaziwa kakhulu ngokuthi i-polymer.I-PTFE, esetshenziswa kaningi ezinhlelweni ezifana nokuvala kanye nolayini, ikhiqiza udoti omningi ekukhiqizeni.Ukuyiphrinta kwe-3D - okuzoba i-3M yokuqala ukuyenza - kuzonciphisa kakhulu lowo monakalo.Ngaphezu kwalokho, izinkampani ezisebenzisa le nqubo zizokwazi ukwenza izakhiwo ze-polymer eziyinkimbinkimbi, ezinezingxenye eziningi endaweni eyodwa kunokuba zibumbe futhi zihlanganise izingxenye eziningi.
