Uhulumeni wase-United States utshala izigidi ezingu-15 zamaRandi ekuthuthukiseni isizukulwane esilandelayo sobuchwepheshe bokuphrinta be-3D bensimbi futhi i-3D Systems ihlanganisa amandla ephrojekthi yokunyathelisa yensimbi ye-3D.
Iphrinta enkulu ye-Metal 3D
Le nkontileka emangalisayo yamaRandi ayizigidi ezingu-15 iqondiswe ngokusemthethweni emsebenzini “ukwakha iphrinta yensimbi ye-3D enkulu kunazo zonke, eshesha kakhulu, nenembe kunawo wonke emhlabeni.” Ingabe sizwa ihlombe elidumayo ngemuva?
Amaphrinta amaningi efomethi enkulu ye-3D awanembile, njengoba yakhelwe isivinini - esimaka amabhokisi amabili - ngaphezu kokunemba. Noma kunjalo, isikhathi esiningi lapho sicabanga ngefomethi enkulu, sicabanga ngamasistimu asekelwe ku-extrusion, lapho ama-nozzle anobubanzi obukhulu abeka phansi izendlalelo ezinkulu, okuholela kulowo mphumela wokuphrinta onganembe kangako. Lokho ngeke kube ubuchwepheshe obudlalwayo ngalesi simiso esisha, njengoba kuzoba inqubo yombhede oyimpushana, nanoma yimiphi eminye imininingwane yenqubo engacacisiwe.
Okumenyezelwe ivolumu yokwakha elindelwe, okuthi 1000 x 1000 x 600 mm inkulu ngempela - kalula okungenani phakathi kwezinkulu kunazo zonke emakethe manje. Uhlelo futhi ludinga ubuncane bokujiya kodonga obungu-100µm nogqinsi lwesendlalelo esingu-30µm.
Umsebenzi usuka esivumelwaneni phakathi kwe-Combat Capabilities Development Command Army Research Laboratory (ARL) kanye ne-3D Systems, yona kanye neNational Center for Manufacturing Sciences (NCMS) yasayina inkontileka ne-ARL kanye ne-Advanced Manufacturing, Materials, and Processes (AMMP). ) Uhlelo. Yebo, lokho kuzwakala kukahulumeni: AM nge-3DS, i-ARL, i-NCMS, ne-AMMP.
Ukuphrinta Kwe-3D Kwezempi
Ibutho lase-US lisebenze ngokuphrinta kwe-3D iminyaka engaphezu kwengu-20, futhi belikhulisa utshalomali lwalo eminyakeni yamuva nje.
Abaningi bacabanga kuqala isikhali - okuzwakala sengathi kuyabonakala okungenani ngezinga elithile kule phrojekthi - lapho ucabanga ngezicelo zempi, kodwa izinkomishi zekhofi, izimoto, izingxenye ezisele ezenziwe endaweni, ngisho nokusindisa ukuphila amathuluzi ezokwelapha ubone ukusetshenziswa kokuphrinta kwe-3D kube nomphumela omuhle ensimini. Okuthakazelisa kakhulu amabutho ahlomile ithemba ukunciphisa uchungechunge lokuhlinzeka, ikakhulukazi ngokufakwa ngaphakathi kwenkundla kwemishini engaphrinta izingxenye ezishintshayo noma amathuluzi akhethekile njengoba kudingeka lapho amasosha ekude namadepho afanelekile okubuyisela isitokwe kabusha.
Futhi yilokho okugxilwe kukho lapha: amaketanga okunikezela ngezikhali zebanga elide, izimoto zokulwa, izindiza ezinophephela emhlane, nokuvikela emoyeni nemicibisholo.
Umgomo wohlelo olusha uwukuthola izingxenye ezisebenzisekayo, ezihlala isikhathi eside ensimini ngokuphumelelayo nangokushesha, nangokusetshenziswa kwempahla encane, kunezinketho zamanje zokukhiqiza.
3D Systems In Defense
Ngakolunye uhlangothi, i-3D Systems nayo inomlando osunguliwe namasosha, okuhlanganisa ukusebenza ne-US Marine Corps. Inkontileka ne-ARL yakhela kunoma yimuphi umsebenzi wangaphambili, nokho, njengoba ingasebenzisi nje kuphela iphothifoliyo ekhona ye-3D Systems kodwa ubuchwepheshe eyakhelwe phezu kwabo ukuze kuthuthukiswe le phrinta yensimbi entsha ye-3D.
Ukusetshenziswa kokuqala kuzoba semadepho namalebhu eButho, bese kuhlelwa ukunwetshwa “kubahlinzeki bezindiza abahamba phambili nokuvikela,” kugcinwe ukutholakala okubanzi kulokho okungase kube uhlelo oluthuthuke kakhulu.
Ngokusekelwe kuphothifoliyo ekhona ye-3D Systems kanye nokuphawula okuvela esimemezelweni, kubonakala kucacile ukuthi uhlelo olusha olukhulu luzoba inqubo ye-powder bed laser.
"Kuze kube manje, amaphrinta we-powder bed laser 3D abemancane kakhulu, ahamba kancane, futhi awacacile kakhulu ukukhiqiza amasistimu amakhulu wokulwa emhlabathini ngesilinganiso," kusho uDkt. Joseph South, umphathi wohlelo lwe-ARL lweSayensi ye-Additive Manufacturing ye-Next Generation Munitions.
Iminikelo yenkampani ekhona ye-DMP (Direct Metal Printing) yakhe isisekelo sobuchwepheshe kule nqubo; umnikelo omkhulu wamanje kulayini, I-DMP Factory 500, inomthamo wokwakha ongu-500 x 500 x 500 mm, okugqamisa ukuthi ngempela umgomo omusha uwukunyuka okukhulu.
Okuningi Ngezinhlelo ze-3D
Kuzodingeka silinde ukuze sibone ukuthi yiziphi izindaba ezizodalulwa njengoba le phrojekthi iqhubeka; njengoba kungokwebutho, kukhona konke okungenzeka ukuthi ngeke sizwe okuningi mayelana nemingcele ethile, amakhono, futhi ikakhulukazi amaphrojekthi.
Kodwa futhi kungenzeka ukuthi sizwe kabanzi mayelana nohlelo; ukukhululwa kuphinde kuphawule:
"Ngaphezu kokuletha isisombululo esisha sensimbi ye-AM eButhweni Lezempi, i-3D Systems izophinde ihlole ukuthi kungenzeka yini ukuhlanganisa ubuchwepheshe obusha nezinqubo kuphothifoliyo yayo ekhona yobuchwepheshe bephrinta ye-3D."
Ngakho-ke mhlawumbe kunethuba lokuthi ngaphezu kokukhiphela abahlinzeki bendawo yezindiza nezokuvikela, uhlelo (noma okunye ukutholwa kwalo) luzongena kwiphothifoliyo ye-3D Systems etholakalayo kwezohwebo.
Amazwana avela 3D Izinhlelo Umsunguli kanye no-CTO (nobaba we-SLA) u-Chuck Hull baphinde bakhombise ukuthi imizamo yokuthuthukisa inweba ukudlula iphrinta ye-3D, njengoba asho:
“Ngale phrojekthi, sibheke ngabomvu ukuletha uhlelo lokukhiqiza olusebenzayo njengezinye… I-ARL isiwabonile kakade amandla e-AM okuguqula ukusebenza kwayo. Sibheke ngabomvu ukubambisana nabo ukuze sikhulise futhi sandise la makhono ngokuletha izinqubo, izinto zokwakha kanye nobuchwepheshe bokuqala ukuya emakethe.”
Ingabe izoba enkulu kunazo zonke, esheshayo, enembe kakhulu? Sizobona!
