chidziwitso

Kusindikiza kwa 3D kwasintha kupanga m'mafakitale osiyanasiyana, kumapereka kusinthasintha kosaneneka komanso kuchita bwino. Pamene teknoloji ikupita patsogolo, zipangizo zatsopano zikufufuzidwa kuti zikhale ndi mphamvu pakupanga zowonjezera. Chimodzi mwazinthu zotere zomwe zachititsa chidwi kwambiri ndi ufa wa titaniyamu. Positi iyi yabulogu imayang'ana zomwe zingatheke komanso zovuta za 3D kusindikiza ndi koyera titaniyamu ufa, kuyankha mafunso ofunikira ndikupereka zidziwitso pakugwiritsa ntchito kopitilira muyeso.

Kodi ubwino wa kusindikiza kwa 3D ndi titaniyamu wangwiro ndi chiyani?

Kusindikiza kwa 3D ndi ufa wa titaniyamu kumapereka maubwino ambiri omwe amapangitsa kuti ikhale njira yowoneka bwino m'mafakitale osiyanasiyana, makamaka gawo lazamlengalenga, zamankhwala, ndi zamagalimoto. Ubwino waukulu wa titaniyamu ndi zinthu zapadera za titaniyamu, kuphatikiza kuchuluka kwake kwamphamvu ndi kulemera kwake, kukana dzimbiri, komanso kuyanjana kwachilengedwe.

Mukagwiritsidwa ntchito posindikiza za 3D, ufa wa titaniyamu wangwiro umalola kuti pakhale ma geometries ovuta omwe angakhale ovuta kapena osatheka kuti akwaniritsidwe pogwiritsa ntchito njira zachikhalidwe zopangira. Izi zimatsegula mwayi watsopano wokonza mapangidwe, zomwe zimathandiza mainjiniya kupanga zida zopepuka koma zolimba zomwe zitha kupititsa patsogolo magwiridwe antchito azamlengalenga kapena kuchepetsa zinyalala zazinthu zamagalimoto.

M'zachipatala, kusindikiza kwa 3D ndi ufa wa titaniyamu koyera kwasintha kupanga ma implants ndi ma prosthetics. Kukhoza kupanga mapangidwe okhudzana ndi odwala kumapangitsa kuti ntchito ikhale yabwino komanso yowonjezereka, zomwe zimapangitsa kuti pakhale zotsatira zabwino komanso kuchepetsa nthawi yochira. Kuphatikiza apo, biocompatibility ya titaniyamu imapangitsa kukhala chinthu choyenera kuyikapo kwa nthawi yayitali, chifukwa imalumikizana bwino ndi minofu yamunthu ndipo imakhala ndi chiopsezo chochepa chokanidwa.

Makampani opanga zamlengalenga nawonso alowa nawo 3D kusindikiza ndi koyera titaniyamu ufa chifukwa cha kuthekera kwake kuchepetsa thupi komanso kukulitsa magwiridwe antchito. Mwa kukhathamiritsa mapangidwe ndi kuchepetsa kuchuluka kwa zigawozi mwa kuphatikiza, opanga amatha kupanga zida zogwira mtima komanso zotsika mtengo zandege ndi zakuthambo.

Kuphatikiza apo, kusindikiza kwa 3D ndi ufa wa titaniyamu koyera kumapereka maubwino ofunikira pakuchita bwino kwazinthu. Njira zachikale zopangira ma subtractive nthawi zambiri zimabweretsa zinyalala zambiri, makamaka pogwira ntchito ndi zinthu zodula monga titaniyamu. Mosiyana ndi izi, njira zopangira zowonjezera zimagwiritsa ntchito kuchuluka kwazinthu zofunikira zokha, kuchepetsa zinyalala ndikuchepetsa ndalama zonse zopangira.

Kusinthasintha kwa kusindikiza kwa 3D kumathandizanso kuti ma prototyping mwachangu komanso kukonzanso kamangidwe kake. Izi zitha kufulumizitsa kwambiri kayendetsedwe kazinthu, ndikupangitsa makampani kubweretsa zida za titaniyamu kuti zigulitse mwachangu komanso moyenera.

Kodi njira yosindikizira ya 3D imagwira ntchito bwanji ndi ufa wa titaniyamu?

Njira yosindikizira ya 3D yokhala ndi titaniyamu ufa wangwiro amagwiritsa ntchito matekinoloje osankhidwa a laser melting (SLM) kapena electron beam melting (EBM). Njira zopangira zowonjezerazi zimagwera m'gulu la njira zophatikizira bedi la ufa, pomwe zigawo zopyapyala za ufa wachitsulo zimasungunuka ndikusakanikirana kuti zipange chinthu chofunidwa chamitundu itatu.

Mu ndondomeko ya SLM, laser yamphamvu kwambiri imagwiritsidwa ntchito kusungunula ndi kusakaniza titaniyamu ufa particles. Njirayi imayamba ndi ufa wochepa kwambiri womwe umafalikira pa nsanja yomanga. Laser ndiye amatsata gawo la gawolo, ndikusungunula ufawo m'malo enieni. Gawo likatha, nsanja yomanga imatsitsidwa, ndipo ufa watsopano umafalikira pamwamba. Njirayi imabwerezedwa wosanjikiza ndi wosanjikiza mpaka gawo lonse limangidwe.

EBM, kumbali ina, imagwiritsa ntchito mtengo wa electron m'malo mwa laser kuti isungunuke ufa wa titaniyamu. Izi zimachitika mu chipinda chosungiramo mpweya komanso kutentha kwapamwamba, komwe kungapangitse magawo okhala ndi ma microstructures osiyanasiyana ndi katundu poyerekeza ndi omwe amapangidwa ndi SLM.

Njira zonsezi zimafunikira kuwongolera mosamala magawo osiyanasiyana, kuphatikiza mphamvu ya laser kapena ma elekitironi, kuthamanga kwa sikani, makulidwe osanjikiza, ndi mawonekedwe a ufa. Kuyera ndi kukula kwa tinthu ta titaniyamu ndi zinthu zofunika kwambiri zomwe zimakhudza mtundu womaliza wa gawo losindikizidwa.

Chimodzi mwazovuta pakusindikiza kwa 3D ndi ufa woyera wa titaniyamu imayang'anira kuchuluka kwa zinthu zomwe zili ndi mpweya. Titaniyamu imapanga oxide wosanjikiza mosavuta ikakumana ndi mpweya, zomwe zingakhudze mtundu wa zida zosindikizidwa. Kuti muchepetse nkhaniyi, kusindikiza kumachitika mumlengalenga, monga mpweya wa argon, kuteteza okosijeni.

Masitepe pambuyo pokonza nthawi zambiri amakhala ofunikira kuti mukwaniritse zomwe mukufuna kumaliza komanso makina amakina. Izi zingaphatikizepo chithandizo cha kutentha kuti muchepetse kupsinjika kwamkati, kutentha kwa isostatic pressing (HIP) kuti muchepetse porosity, ndi njira zosiyanasiyana zomaliza pamwamba kuti gawolo liwonekere ndikuchita bwino.

Njira yosindikizira ya 3D yokhala ndi ufa wa titaniyamu wangwiro imapereka maubwino apadera potengera ufulu wamapangidwe komanso magwiridwe antchito. Komabe, zimafunikiranso zida zapadera, ukatswiri, ndikuwongolera mosamala magawo azinthu kuti apange magawo apamwamba nthawi zonse.

Kodi zovuta ndi zolephera za kusindikiza kwa 3D ndi titaniyamu koyera ndi chiyani?

pamene 3D kusindikiza ndi koyera titaniyamu ufa imapereka zabwino zambiri, imabweranso ndi zovuta zake ndi zolepheretsa zomwe ziyenera kuthetsedwa kuti zitheke.

Chimodzi mwa zovuta zazikulu ndi mtengo wokwera wokhudzana ndi ndondomekoyi. Titaniyamu ufa woyera ndi wokwera mtengo chifukwa cha njira zopangira zovuta zomwe zimafunikira kuti apange mawonekedwe apamwamba, ozungulira oyenerera kusindikiza kwa 3D. Kuphatikiza apo, zida zapadera zomwe zimafunikira pakusindikiza kwa titaniyamu 3D, monga ma laser amphamvu kwambiri kapena makina opangira ma elekitironi, zimayimira ndalama zambiri. Zinthu izi zimathandizira kuti pakhale ndalama zopangira zokwera kwambiri poyerekeza ndi njira zachikhalidwe zopangira kapena kusindikiza kwa 3D ndi zida zina.

Vuto lina lalikulu ndikuwongolera magawo azinthu kuti akwaniritse gawo lokhazikika. Titaniyamu imakhudzidwa kwambiri ndi kusiyanasiyana kwamakonzedwe, ndipo ngakhale kusintha kwakung'ono kumatha kuyambitsa zolakwika kapena ma microstructure osayenera. Zinthu monga mphamvu ya laser, kuthamanga kwa sikani, makulidwe osanjikiza, ndi kutentha kwa bedi la ufa ziyenera kukonzedwa bwino pakugwiritsa ntchito kulikonse. Izi nthawi zambiri zimafuna kuyesa kwakukulu ndi chitukuko cha ndondomeko, zomwe zingakhale zowononga nthawi komanso zodula.

Kuchulukanso kwa titaniyamu ndi okosijeni kumabweretsa vuto lina. Ngakhale kufufuza kuchuluka kwa okosijeni kungachititse kuti embrittlement ndi kuchepetsa makina katundu mu gawo lomaliza. Izi zimafuna kugwiritsa ntchito ufa woyenga kwambiri ndi mpweya wa inert panthawi yosindikiza, zomwe zimapangitsa kuti zikhale zovuta komanso zotsika mtengo. Kuonjezera apo, kugwira ndi kusunga ufa wa titaniyamu kumafunika kusamala mwapadera chifukwa cha kuyaka kwake komanso kuopsa kwa thanzi.

Kukula kwa gawo ndi malire ena pakusindikiza kwa 3D ndi ufa wa titaniyamu. Makina amakono ophatikizira bedi la ufa ali ndi ma voliyumu ochepa omanga, omwe amalepheretsa kukula kwa zinthu zomwe zitha kupangidwa. Ngakhale kuti zigawo zazikuluzikulu zingathe kupangidwa mwa kujowina zigawo zing'onozing'ono zingapo, njirayi imayambitsa zovuta zowonjezera komanso zofooka zomwe zingatheke muzomaliza.

Kumaliza ndi kusanja kwapamwamba ndi malo omwe zigawo za titaniyamu zosindikizidwa za 3D zimatha kuperewera poyerekeza ndi zida zopangidwa kale. Njira yomanga yosanjikiza ndi yosanjikiza imatha kupangitsa kuti pakhale mawonekedwe apamwamba, omwe amadziwika kuti "staircase effect," omwe angafunike kukonzanso pambuyo pake kuti mukwaniritse kusalala komwe mukufuna. Izi zitha kukhala zovuta makamaka kwa ma geometries ovuta kapena zamkati zomwe zimakhala zovuta kuzipeza.

Porosity ndi nkhawa inanso mu magawo a titaniyamu osindikizidwa a 3D. Ngakhale njira zotsogola ndi chithandizo chapambuyo pake zimatha kuchepetsa kwambiri porosity, kupeza mbali zowundana zofananira ndi titaniyamu kungakhale kovuta. Izi zitha kukhudza mphamvu zamakina komanso kutopa kwazinthu zosindikizidwa.

Pomaliza, mawonekedwe owongolera magawo a titaniyamu osindikizidwa a 3D, makamaka pakugwiritsa ntchito zovuta monga zakuthambo ndi zoyika zachipatala, akusinthabe. Njira zoperekera ziphaso ndi ziyeneretso zamagulu opangidwa ndi titaniyamu zitha kukhala zovuta komanso zowononga nthawi, zomwe zingachedwetse kukhazikitsidwa m'mafakitale ena.

Ngakhale pali zovuta izi, kafukufuku wopitilira ndi ntchito zachitukuko akuwongolera mosalekeza njira yosindikizira ya 3D ufa woyera wa titaniyamu. Kupita patsogolo pakupanga ufa, kuwongolera njira, ndi njira zosinthira pambuyo pakukonza zikuthana ndi zolephera zambiri izi, zomwe zikutsegulira njira yotengera ukadaulo wosinthikawu.
