Metal 3D kudhinda

Munguva ichangopfuura, takaita kuratidzwa kwesimbi3D kudhinda, uye takaipedza zvakabudirira, saka chii chinonzi simbi3D kudhinda? Ndezvipi zvayakanakira nezvayakaipira?

Metal 3D kudhinda ndeye yekuwedzera yekugadzira tekinoroji inovaka matatu-dimensional zvinhu nekuwedzera simbi zvinhu layer by layer. Heino yakadzama sumo yesimbi 3D kudhinda:

Technical musimboti
Selective Laser sintering (SLS): Kushandiswa kweakakwira simba laser matanda kunyungudusa uye sinter simbi hupfu, kupisa hupfu hwehupfu kusvika kune tembiricha pazasi pekunyungudika kwayo, kuitira kuti zvisungo zvesimbi pakati pehupfu zvigadziriswe, nekudaro zvichivaka chinhu chakaturikidzana. Muchirongwa chekudhinda, yunifomu yehupfu yesimbi inotanga kuiswa pachikuva chekudhinda, uyezve laser danda rinotarisa hupfu zvinoenderana nechikamu-chikamu chimiro chechinhu, kuitira kuti hupfu hwakaongororwa hunyunguduke uye hugosimba pamwechete, mushure mekupedzwa kwekudhinda, chikuva chinodonhedza imwe chinhambwe, chobva chaparadzira hupfu hutsva, dzokorora chinhu chiri pamusoro apa chadhindwa.
Sarudzo Laser Melting (SLM) : Zvakafanana neSLS, asi neakakwira laser simba, iyo simbi poda inogona kunyungudutswa kuita denser chimiro, yakakwira density uye zvirinani zvemichina zvivakwa zvinogona kuwanikwa, uye kusimba uye nekurongeka kweakadhindwa simbi zvikamu zvakakwirira, padyo kana kutopfuura zvikamu zvinogadzirwa nemaitiro echinyakare ekugadzira. Inokodzera kugadzira zvikamu muaerospace, midziyo yekurapa uye mamwe minda inoda kurongeka kwakanyanya uye kuita.
Electron beam melting (EBM): Kushandiswa kwemaerekitironi matanda sesimba rinonyungudutsa hupfu hwesimbi. Erekitironi danda rine hunhu hwepamusoro simba density uye high scanning speed, iyo inogona kukurumidza kunyungudutsa simbi hupfu uye kunatsiridza kudhinda. Kudhinda munzvimbo yevacuum kunogona kudzivirira kuita kwezvinhu zvesimbi neokisijeni panguva yekudhinda, iyo yakakodzera kudhinda titanium alloy, nickel-based alloy uye zvimwe zvinhu zvesimbi zvine hanya neokisijeni yemukati, inowanzoshandiswa muaerospace, midziyo yekurapa nemimwe minda yepamusoro.
Metal material extrusion (ME): Material extrusion based kugadzira nzira, kuburikidza nemusoro weextrusion kuti uburitse simbi zvinhu muchimiro chesirika kana paste, uye panguva imwe chete kupisa uye kurapa, kuitira kuti uwane layer ne layer accumulation molding. Kuenzaniswa nelaser kunyungudika tekinoroji, mari yekudyara yakaderera, inoshanduka uye iri nyore, kunyanya yakakodzera kusimudzira kwekutanga munzvimbo yehofisi uye nharaunda yemaindasitiri.
Zvinhu zvakajairika
Titanium alloy: ine mabhenefiti ekusimba kwepamusoro, kuderera kwehudhi, kunaka kwekusagadzikana uye biocompatibility, inoshandiswa zvakanyanya muaerospace, midziyo yekurapa, mota nemimwe minda, senge mapanga einjini yendege, majoini ekugadzira uye zvimwe zvikamu zvekugadzira.
Stainless simbi: ine yakanaka corrosion resistance, mechanical properties and processing properties, ine mari shoma, ndechimwe chezvinhu zvinowanzoshandiswa musimbi 3D kudhinda, inogona kushandiswa kugadzira zvakasiyana-siyana zvemakina zvikamu, zvishandiso, midziyo yekurapa nezvimwe zvakadaro.
Aluminium alloy: yakaderera density, yakakwirira simba, yakanaka yekupisa conductivity, yakakodzera kugadzira zvikamu zvine huremu hunodiwa, senge mota injini cylinder block, aerospace structural parts, nezvimwe.
Nickel-based alloy: ine yakanakisa tembiricha yekusimba, corrosion resistance uye oxidation kuramba, inowanzoshandiswa mukugadzira zvinhu zvekushisa zvakanyanya senge injini dzendege nematurbine egasi.
advantage
Yakakwira dhizaini yerusununguko rwekugadzira: Kugona kuzadzisa kugadzirwa kweakaomesesa maumbirwo uye zvimiro, senge lattice zvimiro, topologically optimized zvimiro, nezvimwewo, izvo zvakaoma kana zvisingagoneke kuwana mumaitiro echinyakare ekugadzira, inopa yakakura innovation nzvimbo yekugadzirwa kwechigadzirwa, uye inogona kugadzira yakareruka, yepamusoro-inoshanda zvikamu.
Deredza huwandu hwezvikamu: zvikamu zvakawanda zvinogona kubatanidzwa mune yese, kuderedza kuwirirana uye nzira yegungano pakati pezvikamu, kuvandudza kushanda kwekugadzira, kuderedza mari, asiwo kunatsiridza kuvimbika uye kugadzikana kwechigadzirwa.
Rapid prototyping: Inogona kuburitsa prototype yechigadzirwa munguva pfupi, kukurumidza kutenderera kwechigadzirwa, kuderedza kutsvagisa nemitengo yekusimudzira, uye kubatsira mabhizinesi kuunza zvigadzirwa kumusika nekukurumidza.
Kugadzirwa kwakagadziridzwa: Zvinoenderana nezvinodiwa zvega ega zvevatengi, zvigadzirwa zvakasarudzika zvinogona kugadzirwa kuti zvizadzise zvinodiwa nevatengi vakasiyana, zvakakodzera kuisirwa ekurapa, zvishongo uye mamwe minda yakagadziridzwa.
Kuganhurirwa
Hunhu husina kunaka hwepamusoro: Kushata kwepamusoro kwezvikamu zvesimbi zvakadhindwa zvakakwirira, uye mushure mekurapa kunodiwa, sekukuya, kupukuta, kuputika kwejecha, nezvimwewo, kuvandudza kupera kwepamusoro, kuwedzera mutengo wekugadzira uye nguva.
Kukanganisa kwemukati: panogona kunge paine hurema hwemukati senge pores, zvidimbu zvisina kusanganiswa, uye fusion isina kukwana panguva yekudhinda, iyo inokanganisa ma mechanic properties yezvikamu, kunyanya mukushandiswa kwemutoro wakakwira uye cyclic mutoro, zvinodikanwa kudzikisa kuitika kwehurema hwemukati nekugadzirisa maparamita ekudhinda uye kutora nzira dzakakodzera dzepashure pekugadzirisa.
Zvinhu zvinogumira: Kunyangwe mhando dzesimbi 3D dzekudhinda zvinhu dziripo dziri kuwedzera, pachine zvimwe zvisingakwanisike zvichienzaniswa nemaitiro ekugadzira echinyakare, uye zvimwe zvemhando yepamusoro zvesimbi zvinonyanya kuoma kudhinda uye mutengo wakakwira.
Mutengo wenyaya: Mutengo wesimbi 3D midziyo yekudhindisa uye zvinhu zvakati wandei uye kumhanya kwekudhinda kunononoka, izvo zvisingadhure semaitiro echinyakare ekugadzira kugadzirwa kwakakura, uye parizvino inonyanya kukodzera batch diki, kugadzirwa kwakagadziridzwa uye nzvimbo dzine chigadzirwa chepamusoro uye zvinodiwa zvemhando yepamusoro.
Tekinoroji yakaoma: Metal 3D kudhinda kunosanganisira yakaoma maparamita uye maitiro ekutonga, izvo zvinoda nyanzvi vanoshanda uye tsigiro yehunyanzvi, uye inoda yakakwirira tekinoroji uye ruzivo rwevashandisi.
Nzvimbo yekushandisa
Aerospace: Inoshandiswa kugadzira aero-injini blades, turbine discs, mapapiro zvimiro, setiraiti zvikamu, nezvimwewo, izvo zvinogona kuderedza huremu hwezvikamu, kuvandudza kushanda kwemafuta, kuderedza mutengo wekugadzira, uye kuve nechokwadi chekushanda kwepamusoro uye kuvimbika kwezvikamu.
Mota: Gadzira mota injini cylinder block, transmission shell, lightweight structural parts, etc., kuti uwane huremu dhizaini yemotokari, kuvandudza hupfumi hwemafuta uye kuita.
Chiremba: Kugadzirwa kwemidziyo yekurapa, majoini ekugadzira, mazino orthotics, midziyo yekurapa inoisirwa, nezvimwewo, zvichienderana nekusiyana kwevarwere kwakagadziridzwa kugadzira, kunatsiridza kukodzera kwemidziyo yekurapa uye kurapwa.
Kugadzira mold: Kugadzira majekiseni majekiseni, kufa kukanda mold, nezvimwewo, kupfupisa kutenderera kwekugadzira mold, kuderedza mutengo, kunatsiridza iko kurongeka uye kuoma kwe mold.
Electronics: Gadzira ma radiator, mabhomba, edunhu mabhodhi emidziyo yemagetsi, nezvimwewo, kuti uwane yakasanganiswa kugadzirwa kwezvimiro zvakaomarara, kuvandudza mashandiro uye kupisa kupisa mhedzisiro yemidziyo yemagetsi.
Zvishongo: Zvinoenderana nehunyanzvi hwemugadziri uye zvinodiwa nevatengi, akasiyana ezvishongo akasarudzika anogona kugadzirwa kuti avandudze kugona kwekugadzira uye kugadzirisa kwechigadzirwa.
