Kusindikiza kwa Metal 3D

Posachedwapa, tinapanga chiwonetsero chazitsulo3D kusindikiza, ndipo tinamaliza bwino kwambiri, ndiye chitsulo ndi chiyani3D kusindikiza? Kodi ubwino ndi kuipa kwake ndi kotani?

Kusindikiza kwa Metal 3D ndiukadaulo wopanga zowonjezera womwe umapanga zinthu zitatu-dimensional powonjezera zida zachitsulo zosanjikiza. Nawa tsatanetsatane wa kusindikiza kwachitsulo kwa 3D:

mfundo zaukadaulo
Selective laser sintering (SLS) : Kugwiritsa ntchito matabwa amphamvu a laser kuti asungunuke mosankha ndi ufa wachitsulo wa sinter, kutenthetsa zinthu za ufa ndi kutentha pang'ono pansi pa malo ake osungunuka, kotero kuti zomangira zachitsulo pakati pa particles ufa zimapangidwira, potero zimamanga chinthu chosanjikiza ndi wosanjikiza. Mu ndondomeko yosindikiza, yunifolomu wosanjikiza wa ufa chitsulo choyamba anaika pa nsanja yosindikiza, ndiyeno mtengo laser mapanga sikani ufa molingana ndi mawonekedwe mtanda gawo la chinthu, kotero kuti jambulani ufa amasungunula ndi solidifies pamodzi, akamaliza wosanjikiza kusindikiza, nsanja akutsikira mtunda winawake, ndiyeno kufalitsa wosanjikiza watsopano wa ufa, kubwereza chinthu pamwamba mpaka kusindikizidwa lonse.
Selective Laser Melting (SLM) : Mofanana ndi SLS, koma ndi mphamvu yapamwamba ya laser, ufa wachitsulo ukhoza kusungunuka kwathunthu kuti upangitse mawonekedwe osakanikirana, kachulukidwe kapamwamba komanso makina abwino kwambiri amatha kupezeka, ndipo mphamvu ndi kulondola kwa zigawo zazitsulo zomwe zasindikizidwa ndizokwera kwambiri, pafupi kapena kupitirira mbali zomwe zimapangidwa ndi chikhalidwe chopanga. Ndioyenera kupanga zida zazamlengalenga, zida zamankhwala ndi magawo ena omwe amafunikira kulondola kwambiri komanso magwiridwe antchito.
Electron beam melting (EBM) : Kugwiritsa ntchito mitengo ya ma elekitironi ngati gwero lamphamvu kusungunula ufa wachitsulo. Mtengo wa elekitironi uli ndi mawonekedwe amphamvu kwambiri komanso kuthamanga kwambiri kwa sikani, komwe kumatha kusungunula ufa wachitsulo ndikuwongolera kusindikiza bwino. Kusindikiza m'malo opanda mpweya kungapewere zomwe zida zachitsulo ndi okosijeni panthawi yosindikiza, zomwe zili zoyenera kusindikiza aloyi ya titaniyamu, aloyi ya nickel ndi zipangizo zina zachitsulo zomwe zimakhudzidwa ndi mpweya wa okosijeni, zomwe zimagwiritsidwa ntchito mumlengalenga, zipangizo zamankhwala ndi minda ina yapamwamba.
Metal chuma extrusion (ME) : Zinthu extrusion zochokera kupanga njira, kudzera extrusion mutu extrude zitsulo zakuthupi mu mawonekedwe a silika kapena phala, ndi nthawi yomweyo kutentha ndi kuchiritsa, kuti akwaniritse wosanjikiza ndi wosanjikiza kudzikundikira akamaumba. Poyerekeza ndi ukadaulo wosungunuka wa laser, mtengo wandalama ndi wotsika, wosinthika komanso wosavuta, makamaka woyenera kutukuka koyambirira kwamaofesi komanso malo ogulitsa.
Zida wamba
Titaniyamu aloyi: ali ndi ubwino mphamvu mkulu, otsika kachulukidwe, zabwino dzimbiri kukana ndi biocompatibility, chimagwiritsidwa ntchito zakuthambo, zipangizo zachipatala, magalimoto ndi madera ena, monga masamba injini ndege, mfundo yokumba ndi mbali zina kupanga.
Chitsulo chosapanga dzimbiri: ali ndi kukana bwino kwa dzimbiri, katundu wamakina ndi zinthu zopangira, zotsika mtengo, ndi chimodzi mwazinthu zomwe zimagwiritsidwa ntchito posindikiza zitsulo za 3D, zitha kugwiritsidwa ntchito kupanga zida zosiyanasiyana zamakina, zida, zida zamankhwala ndi zina zotero.
Aluminiyamu aloyi: otsika kachulukidwe, mphamvu mkulu, madutsidwe wabwino matenthedwe, oyenera mbali zopangira ndi zofunika kulemera kwambiri, monga galimoto injini yamphamvu chipika, Azamlengalenga mbali structural, etc.
Nickel-based alloy: yokhala ndi mphamvu zotentha kwambiri, kukana dzimbiri komanso kukana kwa okosijeni, imagwiritsidwa ntchito nthawi zambiri popanga zinthu zotentha kwambiri monga injini zandege ndi makina opangira mpweya.
mwayi
Ufulu wapamwamba wa mapangidwe: Kutha kukwaniritsa kupanga mapangidwe ovuta ndi mapangidwe, monga mapangidwe a lattice, mapangidwe opangidwa ndi topologically optimized, ndi zina zotero, zomwe zimakhala zovuta kapena zosatheka kuzikwaniritsa muzopanga zamakono, zimapereka malo ochulukirapo opanga mapangidwe azinthu, ndipo amatha kupanga zopepuka, zogwira ntchito kwambiri.
Chepetsani kuchuluka kwa magawo: magawo angapo amatha kuphatikizidwa muthunthu, kuchepetsa kulumikizana ndi kusonkhana pakati pa magawo, kukonza magwiridwe antchito, kuchepetsa ndalama, komanso kuwongolera kudalirika komanso kukhazikika kwazinthuzo.
Kujambula mwachangu: Imatha kupanga chofananira chazinthu munthawi yochepa, kufulumizitsa kayendetsedwe kazinthu, kuchepetsa mtengo wa kafukufuku ndi chitukuko, ndikuthandizira mabizinesi kubweretsa malonda mwachangu.
Kupanga mwamakonda: Malinga ndi zosowa za makasitomala, zinthu zapadera zimatha kupangidwa kuti zikwaniritse zosowa zapadera za makasitomala osiyanasiyana, oyenera ma implants azachipatala, zodzikongoletsera ndi minda ina yokhazikika.
Kuchepetsa
Kusauka kwapamwamba: Kuwonongeka kwazitsulo zazitsulo zosindikizidwa ndizokwera kwambiri, ndipo chithandizo cham'mbuyo chimafunika, monga kugaya, kupukuta, kupukuta mchenga, ndi zina zotero, kupititsa patsogolo mapeto a pamwamba, kuonjezera mtengo wopangira ndi nthawi.
Mkati zolakwika: pakhoza kukhala zolakwika mkati monga pores, unfused particles, ndi chosakwanira maphatikizidwe pa ndondomeko kusindikiza, zimene zimakhudza makina katundu wa mbali, makamaka ntchito katundu mkulu ndi cyclic katundu, m`pofunika kuchepetsa kupezeka kwa zilema mkati mwa optimizing ndondomeko yosindikiza magawo ndi kutengera njira yoyenera pambuyo pokonza.
Zolepheretsa zakuthupi: Ngakhale mitundu ya zida zosindikizira zachitsulo za 3D zomwe zilipo zikuchulukirachulukira, pali zofooka zina zakuthupi poyerekeza ndi njira zachikhalidwe zopangira, ndipo zida zina zachitsulo zogwira ntchito kwambiri zimakhala zovuta kusindikiza ndipo mtengo wake ndi wokwera.
Mtengo nkhani: Mtengo wa zitsulo 3D zida zosindikizira ndi zipangizo ndi ndi mkulu ndi liwiro kusindikiza ndi pang'onopang'ono, amene si monga okwera mtengo monga miyambo kupanga njira kupanga lalikulu, ndipo panopa makamaka oyenera mtanda waing'ono, kupanga makonda ndi madera ndi ntchito mkulu mankhwala ndi zofunika khalidwe.
Kuvuta kwaukadaulo: Kusindikiza kwa Metal 3D kumaphatikizapo magawo ovuta a ndondomeko ndi kayendetsedwe ka ndondomeko, zomwe zimafuna akatswiri ogwira ntchito ndi chithandizo chaumisiri, ndipo zimafuna luso lapamwamba komanso luso la ogwira ntchito.
Malo ogwiritsira ntchito
Zamlengalenga: Amagwiritsidwa ntchito popanga masamba a injini ya aero-injini, ma turbine discs, mapiko a mapiko, magawo a satana, ndi zina zambiri, zomwe zimatha kuchepetsa kulemera kwa magawo, kuwongolera mafuta, kuchepetsa ndalama zopangira, ndikuwonetsetsa magwiridwe antchito apamwamba komanso kudalirika kwa magawo.
Galimoto: Pangani silinda ya injini yamagalimoto, chipolopolo chotumizira, magawo opepuka, ndi zina zambiri, kuti mukwaniritse mapangidwe opepuka agalimoto, kuwongolera kuchuluka kwamafuta ndi magwiridwe antchito.
Medical: The kupanga zipangizo zachipatala, olowa yokumba, orthotics mano, implantable zipangizo zachipatala, etc., malinga ndi munthu kusiyana kwa odwala makonda kupanga, kusintha kuyenerera kwa zipangizo zachipatala ndi zotsatira mankhwala.
Kupanga nkhungu: Kupanga zisankho jekeseni, zisankho zoponyera kufa, etc., kufupikitsa kuzungulira kwa nkhungu, kuchepetsa ndalama, kuwongolera kulondola komanso zovuta za nkhungu.
Zamagetsi: Pangani ma radiator, zipolopolo, matabwa ozungulira a zida zamagetsi, ndi zina zotero, kuti mukwaniritse kupanga kophatikizana kwazinthu zovuta, kukonza magwiridwe antchito ndi kutentha kwa zida zamagetsi.
Zodzikongoletsera: Malinga ndi luso la wopanga komanso zosowa za makasitomala, zodzikongoletsera zosiyanasiyana zimatha kupangidwa kuti zithandizire kupanga bwino komanso kupanga makonda.
