Abacwaningi abavela eCisco ikhono lokusebenzisa amaphrinta e-3D ukuze enze izigxivizo zeminwe ezingahle zisetshenziswe ukukhohlisa amasistimu okuqinisekisa i-biometric asetshenziswa kuma-smartphone, amakhompyutha aphathekayo, okhiye be-USB nezingidi zikagesi ezivela kubakhiqizi abahlukahlukene. Izindlela zomgunyathi ezithuthukisiwe zahlolwa ezinhlotsheni ezahlukahlukene zezinzwa zeminwe - i-capacitive, i-optical ne-ultrasonic.
Ucwaningo lubonise ukuthi ukusetshenziswa kwemiklamo yeminwe ekopisha izigxivizo zeminwe zesisulu kuvumela ama-smartphones ukuthi avulwe ngokwesilinganiso se-80% yemizamo. Ukwakha i-clone yesigxivizo somunwe, ungenza ngaphandle
ngaphandle kwemishini ekhethekile etholakala kuphela ezinsizeni ezikhethekile, kusetshenziswa iphrinta ye-3D ejwayelekile. Ngenxa yalokho, ukuqinisekiswa kwezigxivizo zeminwe kuthathwa njengokwanele ukuvikela i-smartphone uma kwenzeka ilahleka noma yebiwa idivayisi, kodwa kungasebenzi lapho kwenziwa ukuhlasela okuqondiwe lapho umhlaseli angakwazi khona ukunquma umbono wezigxivizo zeminwe zomuntu ohlukunyeziwe (ngokwesibonelo, ngokuthola ingilazi enezigxivizo zeminwe kuyo).
Kuhlolwe izindlela ezintathu zokwenza izigxivizo zeminwe eziyizisulu zibe yidijithali:
- Ukwenza i-plasticine cast. Isibonelo, lapho isisulu sibanjwa, siqulekile noma sidakiwe.
- Ukuhlaziywa kombhalo oshiywe engilazini noma ebhodleleni. Umhlaseli angalandela isisulu futhi asebenzise into ethintiwe (okuhlanganisa nokubuyisela umbhalo ophelele ezingxenyeni).
- Idala isakhiwo esisuselwe kudatha evela kuzinzwa zezigxivizo zeminwe. Isibonelo, idatha ingatholwa ngokuputshuza imininingwane egciniwe yezinkampani zokuphepha noma amasiko.
Ukuhlaziywa kokuphrinta engilazini kwenziwa ngokudala isithombe sokucaca okuphezulu ngefomethi ye-RAW, lapho kwafakwa khona izihlungi ukuze kwandiswe ukugqama nokwandisa izindawo eziyindilinga zibe indiza. Indlela esekelwe kudatha evela kunzwa yezigxivizo zeminwe ibonakale ingasebenzi kahle, njengoba isixazululo esinikezwe inzwa sasinganele futhi kwakudingeka ukugcwalisa imininingwane evela ezithombeni eziningana. Ukusebenza kahle kwendlela okusekelwe ekuhlaziyweni kwe-imprint engilazini (okuluhlaza okwesibhakabhaka kugrafu engezansi) kwakufana noma kuphakeme nakakhulu kunokusebenzisa i-imprint eqondile (iwolintshi).
Imishini ekwazi ukumelana kakhulu ne-Samsung A70, i-HP Pavilion x360 ne-Lenovo Yoga, ekwazile ngokuphelele ukumelana nokuhlaselwa kusetshenziswa izigxivizo zeminwe zomgunyathi. I-Samsung inothi 9, i-Honor 7x, i-Aicase padlock, i-iPhone 8 ne-MacbookPro, ezihlaselwe ku-95% yemizamo, ziye zancipha.
Ukulungiselela imodeli enezinhlangothi ezintathu zokuphrinta kuphrinta ye-3D, kusetshenziswe iphakheji . Isithombe sokuphrinta sisetshenziswe njengebhulashi le-alpha elimnyama nelimhlophe, elisetshenziswe ukukhipha ukuphrinta kwe-3D. Isakhiwo esidaliwe sasetshenziselwa ukwakha ifomu elingaphrintwa kusetshenziswa iphrinta ye-25D evamile enokulungiswa kwama-microns angu-50 noma angu-0.025 (0.05 kanye no-50 mm). Izinkinga ezinkulu zavela ngokubala ubukhulu bomumo, okumele ufane ncamashi nosayizi womunwe. Phakathi nokuhlolwa, izikhala ezingaba ngu-XNUMX zenqatshwa kuze kutholakale indlela yokubala usayizi odingekayo.
Okulandelayo, kusetshenziswa ifomu eliphrintiwe, ukugcona komunwe kuthululwe, okwasebenzisa impahla yepulasitiki eyengeziwe eyayingafaneleki ukuphrinta kwe-3D okuqondile. Abacwaningi benza izivivinyo ngenani elikhulu lezinto ezihlukene, lapho i-silicone ne-textile adhesives iphumelele kakhulu. Ukwandisa ukusebenza kahle kokusebenza nezinzwa ze-capacitive, i-graphite eqhubayo noma i-aluminium powder yengezwe ku-glue.
