Njengamanje, ukugqashuka okunamandla kwe-COVID-19 kuthinta inhliziyo yawo wonke umuntu, futhi ochwepheshe bezokwelapha nabacwaningi ekhaya naphesheya basebenza kanzima ocwaningweni lwegciwane kanye nokuthuthukiswa kokugoma. Embonini yokuphrinta ye-3D, "imodeli yokuqala ye-3D yokutheleleka okusha kwe-coronavirus yamaphaphu e-China yenziwe ngempumelelo futhi yanyatheliswa", "izibuko zezokwelapha ziphrintiwe nge-3D," futhi "imaski iphrintiwe nge-3D" idonse ukunaka okukhulu.

Izibuko zezokwelapha eziphrinte nge-3d
Akukhona okokuqala iphrinta ye-3D isetshenziswa kwezokwelapha. Ukwethulwa kobuchwepheshe bokukhiqiza okungeziwe kwezokwelapha kubonakala njengenguquko entsha emkhakheni wezokwelapha, osekungene kancane kancane ekusetshenzisweni kokuhlela ukuhlinza, amamodeli okuqeqesha, izinsiza zezokwelapha eziqondene nomuntu siqu kanye nezifakelo zokwenziwa komuntu siqu.
Imodeli yokuzijwayeza yokuhlinzwa
Ngokuhlinzwa okuyingozi kakhulu futhi okunzima, ukuhlela ngaphambi kokuhlinzwa okwenziwa ngabasebenzi bezokwelapha kubaluleke kakhulu. Enqubweni yokuprakthiza yokuhlinzwa yangaphambilini, abasebenzi bezokwelapha ngokuvamile badinga ukuthola idatha yesiguli nge-CT, i-MRI nezinye izinto zokusebenza zokuthwebula izithombe, bese beguqula isithombe sezokwelapha esinezinhlangothi ezimbili sibe idatha engokoqobo enezinhlangothi ezintathu ngesofthiwe. Manje, abasebenzi bezokwelapha bangaphrinta amamodeli e-3D ngokuqondile ngosizo lwamadivayisi afana namaphrinta e-3D. Lokhu akukwazi nje ukusiza odokotela ukuba benze ukuhlela okunembile kokuhlinzwa, ukuthuthukisa izinga lokuphumelela kokuhlinzwa, kodwa futhi kube lula ukuxhumana nokuxhumana phakathi kwabasebenzi bezokwelapha kanye neziguli ohlelweni lokuhlinza.
Odokotela abahlinzayo esibhedlela sedolobha lase-Belfast eNyakatho ye-Ireland basebenzise umfanekiso wezinso ophrintwe u-3d ukuze bahlole kuqala inqubo, basuse ngokuphelele i-cyst yezinso, ukusiza ukufeza ukufakelwa okubalulekile kanye nokwenza kube mfushane ukululama komamukeli.

Umhlahlandlela wokusebenza
Njengethuluzi lokuhlinza elisizayo phakathi nokuhlinzwa, ipuleti lomhlahlandlela wokuhlinzwa lingasiza abasebenzi bezokwelapha ukuthi basebenzise uhlelo lokuhlinza ngokunembile. Njengamanje, izinhlobo zamapuleti omhlahlandlela wokuhlinza zifake ipuleti lomhlahlandlela elihlanganyelwe, ipuleti lomhlahlandlela womgogodla, ipuleti lomhlahlandlela wokufakelwa ngomlomo. Ngosizo lwebhodi lomhlahlandlela wokuhlinza elenziwe iphrinta ye-3D, idatha ye-3D ingatholakala engxenyeni ethintekile yesiguli ngokusebenzisa ubuchwepheshe bokuskena be-3D, ukuze odokotela bakwazi ukuthola ulwazi oluyiqiniso kakhulu, ukuze bahlele kangcono ukusebenza. Okwesibili, ngenkathi kulungiswa ukushiyeka kobuchwepheshe bokukhiqiza amapuleti omhlahlandlela wokuhlinza, ubukhulu kanye nokuma kwepuleti lomhlahlandlela kungalungiswa njengoba kudingeka. Ngokwenza kanjalo, iziguli ezahlukene zingaba nepuleti lomhlahlandlela elihlangabezana nezidingo zabo zangempela. Futhi akubizi ukwenza, futhi ngisho nesiguli esivamile singakwazi ukukukhokhela.
Izinhlelo zokusebenza zamazinyo
Eminyakeni yakamuva, ukusetshenziswa kwephrinta ye-3D kudokotela wamazinyo kube yisihloko esishisayo. Ngokuvamile, ukusetshenziswa kwephrinta ye-3D kudokotela wamazinyo ikakhulukazi kugxile ekwakhiweni nasekukhiqizeni amazinyo ensimbi nezinsimbi ezingabonakali. Ukufika kobuchwepheshe bephrinta ye-3D kudale amathuba amaningi kubantu abadinga izisekelo ukuze benziwe ngokwezifiso. Ezigabeni ezahlukene ze-orthodontics, odokotela bamazinyo badinga izinsimbi ezihlukene. Iphrinta ye-3D ayikwazi nje ukufaka isandla ekuthuthukiseni izinyo enempilo, kodwa futhi yehlise izindleko zezinsimbi.
Kokubili ukuskena ngomlomo kwe-3 d, isoftware yokuklama i-CAD nokusebenzisa i-wax yamazinyo yephrinta engu-3, ??ukugcwaliswa, imiqhele, kanye nokubaluleka kobuchwepheshe bedijithali ukuthi odokotela akudingeki bazenzele imodeli kancane kancane namazinyo okufakelwa, imikhiqizo yamazinyo, yenza. umsebenzi wochwepheshe wamazinyo, kodwa ukuchitha isikhathi esengeziwe sokubuyela ekuxilongweni kwesifo somlomo kanye nokuhlinzwa ngomlomo ngokwayo. Kochwepheshe bamazinyo, nakuba bekude nehhovisi likadokotela, inqobo nje uma idatha yomlomo yesiguli, ingenziwa ngokwezifiso ngokuya ngezidingo zikadokotela zemikhiqizo yamazinyo enembile.
Imishini yokuvuselela
Inani langempela elethwa iphrinta ye-3d yamadivayisi okuvuselela njenge-insole yokulungiswa, isandla se-bionic kanye nosizo lokuzwa akukhona nje ukugcwaliseka kokwenza ngokwezifiso okunembile, kodwa futhi ukushintshwa kwezindlela zokukhiqiza zendabuko ngobuchwepheshe bokukhiqiza obunembile nobusebenzayo ukuze kuncishiswe izindleko zomuntu ngamunye. amadivaysi ezokwelapha okuvuselela ngokwezifiso futhi afinyeze umjikelezo wokukhiqiza. Ubuchwepheshe bephrinta ye-3D buhlukene, futhi izinto zokuphrinta ze-3D zihlukahlukene. I-SLA yokwelapha ubuchwepheshe bephrinta ye-3D isetshenziswa kabanzi ekufanekiseni okusheshayo embonini yemishini yezokwelapha ngenxa yezinzuzo zayo zejubane lokucubungula ngokushesha, ukunemba okuphezulu, ikhwalithi ephezulu yendawo kanye nezindleko ezimaphakathi zezinto ezisetshenziswayo ze-photosensitive resin.

Thatha imboni yezindlu zosizo lokuzwa, eye yaqaphela ukwenziwa ngokwezifiso okukhulu kwephrinta ye-3d, isibonelo. Ngendlela evamile, uchwepheshe udinga ukumodela indlebe yesiguli ukuze enze isikhunta somjovo. Bese besebenzisa ukukhanya kwe-uv ukuze bathole umkhiqizo wepulasitiki. Ukuma kokugcina kwensiza yokuzwa kutholwe ngokubhoboza imbobo yomsindo yomkhiqizo wepulasitiki nangokucubungula ngesandla. Uma kukhona okungahambi kahle kule nqubo, imodeli idinga ukwenziwa kabusha. Inqubo yokusebenzisa iphrinta ye-3d ukwenza insiza yokuzwa iqala ngomklamo wesikhunta se-silicone noma umbono we-canal yendlebe yesiguli, eyenziwa ngeskena esingu-3d. Isofthiwe ye-CAD ibe isisetshenziswa ukuguqula idatha eskeniwe ibe amafayela okuklama angafundwa iphrinta ye-3d. Isoftware ivumela abaklami ukuthi baguqule izithombe ezinezinhlangothi ezintathu futhi bakhe umumo wokugcina womkhiqizo.
Ubuchwepheshe bephrinta ye-3D buthandwa amabhizinisi amaningi ngenxa yezinzuzo zabo zezindleko eziphansi, ukulethwa okusheshayo, akukho ukuhlanganisa kanye nomuzwa oqinile wokuklama. Inhlanganisela yephrinta ye-3D kanye nokwelashwa kwezokwelapha kunikeza ukudlala okugcwele ezicini zokwenza ngokwezifiso kanye ne-prototyping esheshayo. Iphrinta ye-3D iyithuluzi ngomqondo othile, kodwa uma ihlanganiswa nobunye ubuchwepheshe nezinhlelo zokusebenza ezithile, ingaba ivelu elingenamkhawulo nomcabango. Eminyakeni yamuva nje, ngokwanda okuqhubekayo kwesabelo semakethe yezokwelapha yaseChina, ukuthuthukiswa kwemikhiqizo yezokwelapha ephrintiwe ye-3D sekuphenduke inkambiso engenakuvinjelwa. Iminyango kahulumeni kuwo wonke amazinga eShayina iphinde yethula izinqubomgomo eziningi zokusekela ukuthuthukiswa kwemboni yokuphrinta ye-3D yezokwelapha.
Sikholelwa ngokuqinile ukuthi ukuthuthukiswa okuqhubekayo kobuchwepheshe bokukhiqiza okungeziwe kuzoletha izinto ezintsha eziphazamisayo emkhakheni wezokwelapha kanye nemboni yezokwelapha. Ubuchwepheshe bokuphrinta be-Digital 3D buzoqhubeka nokujulisa ukubambisana nemboni yezokwelapha, ukukhuthaza imboni yezokwelapha ekuguquleni okuhlakaniphile, okuphumelelayo kanye nochwepheshe.
