Rau lub hlis tau dhau los txij li kev nthuav qhia ntawm cov yas "Ntiaj Teb Thawj Yam 3D Luam Ntawv Phom Phom". Thiab yog li cov kws tshaj lij los ntawm Texas-based Solid Concepts luam tawm rab yaj phom hlau thawj zaug hauv ntiaj teb. Lawv tau ua qhov no los qhia txog lub peev xwm ntawm kev lag luam niaj hnub 3D luam ntawv thiab tsis tsom mus rau kev siv thev naus laus zis muaj nyob hauv txhua lub tsev. Txawm li cas los xij, tsis ntev los sis tom qab qhov no yuav tshwm sim tsis tau.
Txog kev ua qauv qhia, lub cim M1911 rab phom, tsim los ntawm John Browning, tau ua. Nov yog thawj rab phom nws tus kheej tau siv los ntawm Asmeskas Tub Rog, ua ntej ntawd lawv tsuas muaj rab phom xwb.
Daim duab: Ua haujlwm hloov pauv ntawm M1911 tus kheej nqa rab phom tsim los ntawm John Browning. Lub rab yaj phom tau ua haujlwm nrog pab tub rog Asmeskas txij xyoo 1911 txog 1985.
Cov phom phom tau tsim los siv cov hlau ncaj qha laser sintering (DMLS), tib txoj kev uas NASA siv los luam cov foob pob hluav taws. Tsuas yog cov springs tau ua cais. Tom qab luam ntawv, cov khoom tau ua tiav thiab siv tes ua.
Thaum lub sijhawm xeem, rab phom tau ua pov thawj kom raug.
Cov neeg sawv cev hauv tuam txhab hais tias lawv luam tawm rab phom tsis ua rau cov txheej txheem pheej yig dua thiab nkag tau yooj yim rau txhua tus, tab sis tsuas yog ua kom pom kev ntseeg tau ntawm cov khoom tsim los siv DMLS txoj kev. Cov cuab yeej luam ntawv hlau tsis tuaj yeem yuav tsawg dua $ 10,000, uas feem ntau cov neeg nyiam luam ntawv 3D tsis tuaj yeem them taus. Cov Tswv Yim Ntsws nws tus kheej siv lub tshuab luam ntawv tseem kim dua, saib cov vis dis aus.
Cov Khoom Ntsuas tau ntawv tso cai tsim riam phom thiab cog lus tias yuav tsim thiab xa cov khoom ntawm 3D ntu rau sib dhos rab yaj phom tsis pub dhau tsib hnub. Lawm, tsuas yog neeg xam xaj Asmeskas uas muaj kev tso cai tsim nyog thiaj tuaj yeem xaj yuav.

"Peb tus kws tshaj lij riam phom tua phom 50 phom thiab ntaus ob peb lub ntsej muag nyob deb li 30 meters. Cov riam phom muaj ntau dua 30 lub cim 17-4 stainless hlau thiab 625 Inconel Cheebtsam. Ua kom tiav nws yog xaiv laser sintered (SLS) 3D luam ntawv tuav."
"Tag nrho lub tswv yim ntawm kev siv cov txheej txheem laser sintering rau 3D luam tawm cov riam phom hlau nyob ib puag ncig cov pov thawj ntawm kev ntseeg tau, raug, siv tau hauv kev luam cov hlau ua haujlwm ua ntej thiab cov khoom siv kawg," hais tias Kent Firestone. "Muaj qhov tsis nkag siab ib txwm hais tias laser sintering tsis yog qhov tseeb lossis muaj zog txaus, thiab peb tab tom ua haujlwm los hloov cov txheej txheem thev naus laus zis rau tib neeg."
Lwm qhov kev nkag siab yuam kev txog 3D luam ntawv yog tias nws raug txwv rau lub tshuab luam ntawv desktop, uas tuaj yeem tsuas yog nyem tawm cov ntsiab lus.
Txhawm rau debunk txhua qhov kev ntseeg thiab kev nkag siab yuam kev nyob ib puag ncig 3D luam ntawv, cov kws tsim txuj ci tau tsim qhov ua piv txwv thev naus laus zis yam tsis muaj qhov yuam kev. Cov thawj coj yuav tsis muaj peev xwm ua piv txwv thiab txo qis qhov kev cia siab ntawm kev lag luam no.
Laser sintering yog ib qho ntawm cov txheej txheem tsim khoom raug tshaj plaws, muaj ntau tshaj li txaus los tsim kev sib pauv tau, nruj nruj, sib cuam tshuam cov phom. Cov hlau luam tawm yog qhov zoo tshaj rau qhov ua kom raug raws li qhov porosity thiab kev ua haujlwm raug.
Rifling ntawm riam phom tau tsim, lossis "loj hlob", huv, yam tsis tau ua haujlwm ntxiv. Cov cuab yeej siv tes tsuas yog siv hauv kev kho kom zoo nkauj, tsis cuam tshuam rau cov txheej txheem tau txais tshwj xeeb los ntawm kev luam ntawv.
