Ufa wachitsulo chosapanga dzimbiri chatuluka ngati chida chodalirika pakugwiritsa ntchito kusindikiza kwa 3D m'mafakitale osiyanasiyana, kuphatikiza azachipatala. Makhalidwe ake apadera, monga kukana kwa corrosion, kulimba, ndi biocompatibility, zimapangitsa kuti ikhale njira yabwino yopangira zida zamankhwala ndi ma implants. Pamene teknoloji yosindikizira ya 3D ikupitirirabe patsogolo, kugwiritsa ntchito ufa wosapanga dzimbiri pazachipatala kukukula, kumapereka mwayi watsopano wa zothetsera makonda komanso zovuta zachipatala.

Ubwino wogwiritsa ntchito chitsulo chosapanga dzimbiri posindikiza za 3D pazachipatala ndi chiyani?

Kugwiritsa ntchito ufa wachitsulo chosapanga dzimbiri pakusindikiza kwa 3D pazachipatala kumapereka zabwino zambiri zomwe zimapangitsa kuti ikhale yosangalatsa kwa ofufuza, opanga, ndi akatswiri azachipatala. Chimodzi mwazabwino kwambiri ndi biocompatibility ya zinthuzo, zomwe ndizofunikira kwambiri pama implants azachipatala ndi zida zomwe zimalumikizana mwachindunji ndi thupi la munthu. Chitsulo chosapanga dzimbiri, makamaka magiredi ngati 316L, ali ndi mbiri yakale yogwiritsidwa ntchito pazachipatala chifukwa chokana dzimbiri komanso kutha kupirira chilengedwe chovuta cha thupi.

Ubwino winanso wofunikira ndikutha kupanga ma geometri ovuta komanso mapangidwe makonda. 3D kusindikiza ndi ufa wachitsulo chosapanga dzimbiri amalola kupanga zomangira zovuta zomwe zingakhale zovuta kapena zosatheka kuzikwaniritsa pogwiritsa ntchito njira zachikhalidwe zopangira. Kuthekera kumeneku kumakhala kofunikira kwambiri pazachipatala, pomwe ma implants ndi zida za odwala zimatha kusintha kwambiri zotsatira za chithandizo komanso chitonthozo cha odwala.

Kukhalitsa komanso kulimba kwa zida zachitsulo zosapanga dzimbiri za 3D ndizopindulitsanso kwambiri. Zida zamankhwala ndi ma implants nthawi zambiri zimafunikira kupirira kupsinjika kwamakina ndikugwiritsa ntchito mobwerezabwereza. Mphamvu yachilengedwe ya chitsulo chosapanga dzimbiri ndi kulimba kwake kumapangitsa kuti ikhale yabwino kwambiri pazogwiritsa ntchito ngati izi, kuwonetsetsa moyo wautali komanso kudalirika kwa magawo osindikizidwa.

Kuphatikiza apo, kusindikiza kwa 3D ndi chitsulo chosapanga dzimbiri kumapereka kutha kwapamwamba komanso kulondola kwazithunzi. Izi ndizofunikira kwambiri pazachipatala pomwe miyeso yolondola ndi malo osalala ndizofunikira kuti zigwire bwino ntchito komanso chitetezo cha odwala. Kutha kukwaniritsa zomaliza zapamwamba ndi kuchepetsedwa pang'ono pambuyo pokonza kumachepetsa nthawi yopangira ndi ndalama pamene mukusunga miyezo yofunikira yogwiritsira ntchito mankhwala.

Potsirizira pake, kugwiritsa ntchito makina osindikizira a 3D ndi ufa wachitsulo chosapanga dzimbiri kungapangitse kupanga bwino komanso kopanda mtengo kwa zipangizo zamankhwala. Njira zopangira zowonjezera zimachepetsa zinyalala zakuthupi poyerekeza ndi njira zachikhalidwe zochepetsera, ndipo zimalola kupanga zofunidwa, kuchepetsa kufunikira kwazinthu zazikulu komanso kutsika mtengo kwachipatala.

Kodi njira yosindikizira ya 3D imagwira ntchito bwanji ndi ufa wosapanga dzimbiri?

Njira yosindikizira ya 3D ndi ufa wachitsulo chosapanga dzimbiri Nthawi zambiri amagwiritsa ntchito njira yotchedwa Selective Laser Melting (SLM) kapena Direct Metal Laser Sintering (DMLS). Njira yowonjezera iyi imagwiritsa ntchito ma lasers amphamvu kwambiri kuti asungunuke ndikuphatikiza tinthu tating'ono ting'onoting'ono ting'onoting'ono, ndikumanga chinthu chomwe mukufuna ndi chosanjikiza.

Ndondomekoyi imayamba ndi chitsanzo cha 3D CAD cha chinthu chomwe chiyenera kusindikizidwa. Mtunduwu umadulidwa kukhala magawo oonda, nthawi zambiri kuyambira ma microns 20 mpaka 100 mu makulidwe. Zigawozi zimakhala ngati ndondomeko yosindikizira.

M'chipinda chosindikizira, ufa wochepa kwambiri wa chitsulo chosapanga dzimbiri umafalikira mofanana pa nsanja yomanga. Laser yamphamvu kwambiri imatsata chitsanzo cha gawo loyamba pa bedi la ufa, kusungunula ndi kusakaniza particles pamodzi. Gawoli likatha, nsanja yomanga imatsitsidwa pang'ono, ndipo ufa watsopano umafalikira pamwamba. Njirayi imabwerezedwa wosanjikiza ndi wosanjikiza mpaka chinthu chonsecho chimangidwe.

Chimodzi mwazabwino za njirayi ndikutha kupanga zovuta zamkati ndi ma geometries zomwe sizingatheke ndi njira zachikhalidwe zopangira. Izi ndizothandiza makamaka pazachipatala, pomwe zoyikapo zopangidwira mwamakonda kapena zida zokhala ndi mayendedwe ocholowana mkati kapena ma latisi amatha kupangidwa.

Pambuyo kusindikiza, chinthu amangokhalira pansi pokonza mankhwala. Izi zingaphatikizepo chithandizo cha kutentha kuti muchepetse kupsinjika kwamkati, kuwongolera zinthu zakuthupi, ndikuwonetsetsa bata. Njira zomalizitsira pamwamba monga kupukuta kapena electroplating zitha kugwiritsidwanso ntchito kuti mukwaniritse zomwe mukufuna kuti zigwiritsidwe ntchito pachipatala.

Ndizofunikira kudziwa kuti njira yosindikizira ya 3D ndi ufa wachitsulo chosapanga dzimbiri imafunika kuwongolera mosamala magawo osiyanasiyana, kuphatikiza mphamvu ya laser, kuthamanga kwa sikani, ndi mawonekedwe a ufa. Zinthu izi zimakhudza kwambiri mawonekedwe omaliza a chinthu chosindikizidwa, monga kuchulukana, mphamvu, ndi kumaliza kwapamwamba.

Ndizovuta komanso zolephera zotani zogwiritsa ntchito chitsulo chosapanga dzimbiri cha 3D pazida zamankhwala?

Ngakhale kusindikiza kwa 3D ndi ufa wachitsulo chosapanga dzimbiri kumapereka maubwino ambiri pazachipatala, palinso zovuta zingapo ndi zolephera zomwe ziyenera kuthetsedwa. Chimodzi mwazinthu zodetsa nkhawa kwambiri ndikuwonetsetsa kuti magawo omwe asindikizidwa amakhazikika komanso odalirika. Chikhalidwe chovuta cha ndondomeko yosindikizira ya 3D chimatanthawuza kuti pangakhale kusinthasintha kwa microstructure ndi katundu wa zinthu zosindikizidwa, zomwe ndizofunikira kuti ziwongolere mu ntchito zachipatala.

Vuto lina ndi kuthekera kwa porosity mu 3D zosindikizidwa zitsulo zosapanga dzimbiri. Pores kapena zing'onozing'ono zomwe zili mkati mwazinthu zimatha kukhudza makina ake ndipo zimatha kukhala malo opangira dzimbiri kapena kukula kwa mabakiteriya pazida zamankhwala. Kukwaniritsa kachulukidwe wathunthu ndikuchotsa porosity nthawi zambiri kumafuna kukhathamiritsa mosamala kwa magawo osindikizira ndi njira zosinthira pambuyo pokonza.

Kumaliza pamwamba ndi gawo lina lodetsa nkhawa. Ngakhale kusindikiza kwa 3D kumatha kupanga ma geometri ovuta, mawonekedwe omwe amasindikizidwa azitsulo zosapanga dzimbiri amatha kukhala ovuta ndipo angafunike kukonzanso pambuyo pake kuti akwaniritse bwino ntchito zambiri zamankhwala. Kukonzekera kowonjezeraku kungathe kuwonjezera nthawi ndi mtengo pakupanga.

Kuvomerezedwa ndi malamulo kumabweretsa vuto lina lalikulu. Kugwiritsa ntchito chitsulo chosapanga dzimbiri chosindikizidwa cha 3D pazida zamankhwala kumafuna kuyesedwa kosamalitsa ndi kutsimikizira kuti zigwirizane ndi malamulo okhwima. Kuchita zimenezi kungawononge nthawi komanso kuwononga ndalama zambiri, zomwe zingachepetse kugwiritsa ntchito luso limeneli m’chipatala.

Kuchepetsa kukula kwa matekinoloje amakono osindikizira a 3D kungakhalenso cholepheretsa. Ngakhale ndizoyenera zida zambiri zamankhwala ndi ma implants, zida zazikulu zitha kukhala zovuta kapena zosatheka kupanga pogwiritsa ntchito makina osindikizira a 3D omwe alipo.

Pomaliza, mtengo wa Kusindikiza kwa 3D ndi ufa wachitsulo chosapanga dzimbiri akhoza kukhala apamwamba kuposa njira zachikhalidwe zopangira zopangira zazikulu. Ngakhale imapereka zabwino pakusintha makonda ndi ma geometri ovuta, zida ndi zida zomwe zimagwiritsidwa ntchito posindikiza zitsulo za 3D nthawi zambiri zimakhala zodula kuposa zomwe zimagwiritsidwa ntchito popanga wamba.

Ngakhale pali zovuta izi, kafukufuku wopitilira komanso kupita patsogolo kwaukadaulo kukupititsa patsogolo luso komanso kudalirika kwa kusindikiza kwa 3D ndi ufa wachitsulo chosapanga dzimbiri. Pamene zofookazi zikuyankhidwa, kuthekera kwa teknolojiyi m'chipatala kukupitirizabe kukula, kulonjeza njira zatsopano zothandizira odwala ndi kupanga zipangizo zachipatala.

Ku SHAANXI CXMET TECHNOLOGY CO., LTD, timanyadira zamitundu yathu yayikulu, yomwe imathandizira zosowa zosiyanasiyana zamakasitomala. Kampani yathu ili ndi luso lapadera lopanga ndi kukonza, kuwonetsetsa kuti zinthu zathu ndi zapamwamba komanso zolondola.
