Filament 3D tshuab luam ntawv yog qhov zoo, tab sis lawv feem ntau txwv qhov loj me.Laser sintering printers muab lub txaj loj loj, tab sis lawv kuj nqa tus nqi ntawm $ 250,000.Peb yuav ua li cas? Zoo, ua tsaug rau OpenSLS, nws muaj peev xwm tig koj lub laser. txiav tshuab rau hauv koj tus kheej SLS 3D tshuab luam ntawv.
Peb tau qhia txog OpenSLS ntau zaus ua ntej, tab sis nws zoo li thaum kawg tau ua tiav ntau dua (thiab siv tau) kev daws teeb meem. Tsis ntev los no tau luam tawm tsab xov xwm tshawb fawb ntawm qhib qhov chaw xaiv laser sintering (OpenSLS0 ntawm nylon thiab biocompatible polycaprolactone (PDF)), uas cov ntsiab lus tsim thiab qauv.
Pab neeg no tau tsim kho vajtse uas tuaj yeem tig lub laser cutter nrog lub txaj loj ntawm 60 cm x 90 cm rau hauv SLS printer.beauty?Feem ntau ntawm cov khoom siv yog laser txiav, uas txhais tau tias koj tuaj yeem hloov lub laser cutter rau hauv 3D tshuab luam ntawv.
Cov ntaub ntawv tsim tuaj yeem nrhiav pom ntawm lawv GitHub.Cov khoom siv yuav raug nqi rau koj txog $ 2,000, uas yog txiv laum huab xeeb piv rau lub tshuab luam ntawv laser sintered.Muaj ntau cov ntaub ntawv hauv lawv cov ntawv-peb tsis tuaj yeem npog ntau cov ntaub ntawv hauv ib tsab xov xwm. Yog tias koj thaum kawg tsim ib qho, thov qhia rau peb paub!
Kuv yuav tsum tau nyem rau ntawm ib qho ntawm cov kev sib txuas kom paub seb lawv tab tom tham txog dab tsi.Kuv nug, SLS yog dab tsi?Lol “Selective Laser Sintering (SLS) yog cov txheej txheem tsim khoom ntxiv uas siv lub laser los fuse hmoov raw khoom. rau hauv ib qho khoom 3D qauv. "
Kuv xav paub seb nws puas tuaj yeem siv cov hlau tsis tshua muaj melting point hlau alloys.Kuv paub tias cov lag luam loj SLS drilling rigs tuaj yeem siv txhuas lossis steel hlau, tab sis lub melting point ntawm qee cov hlau dawb yuav tsum nyob hauv thaj tsam ntawm laser txiav tshuab.
Txawm li cas los xij, hlau feem ntau muaj kev cuam tshuam ntau dua thiab thermally conductive dua li yas, yog li txawm tias kuv cia siab tias nws yuav ua haujlwm, nws yuav yooj yim dua los siv cov cua sov ncaj qha, xws li 3D vuam neeg hlau qhia los ntawm hackaday xyoo tas los http://hackaday.com/ 2015/06/13/6-axis-robot-arm-3d-prints-a-metal-bridge/
Zoo, qee qhov kev lag luam siv laser sintering nyob rau hauv txoj kev no, yog li nws tuaj yeem ua tiav.Qhov kev xav tau ntawm ntau cov hmoov hlau yog nyob rau tib yam li qhov kev xav tau ntawm cov hmoov plastics.Ntxiv, muaj ntau cov zinc alloys nrog MP uas tsim nyog. yuav tsum nyob rau hauv qhov ntau ntawm laser txiav machine.Qhov lo lus nug tiag tiag yog, kuv xav tias, seb cov hlau no puas yog cov khoom siv tsim khoom siv tau zoo.
Lub hauv ntej kawg ntawm cov cuab yeej siv feem ntau muaj polarizing optics los nqus lossis hloov lub teeb pom kev deb ntawm lub laser.Tam sim no, qhov xwm txheej no tsis muaj nyob nrog CO2 lasers.Ntxiv rau, tshwj tsis yog tias muaj qhov zoo argon filling lossis lub tshuab nqus tsev nyob hauv lub thawv. , feem ntau cov hlau tsuas yog oxidize (los yog hlawv).Qhov nyuaj thiab nqi ntawm cov hlau ua yog nce sai heev.
Qhov koj sau yog qhov tseeb, uas yog vim li cas kuv xav tias siv cov kaus poom hlau lossis qee qhov brazing alloy uas ua tau ntawm qhov ntsuas kub tsim nyog.
Kuv yuav sim brazing alloys.Kuv xav tias lawv yuav muab cov txiaj ntsig zoo tshaj plaws nrog qhov tsawg tshaj plaws ntawm cov hlau lom.
Daim duab ntawm OLD_HACK yog tsim nyog sau cia: nws yog ib lub laser xiav.Rau liab qab hlau, lub nqus spectrum yuav zoo dua CO2 laser.Qhov no kuj txhais tau hais tias ntau tsawg beam yog reflected rov qab mus rau lub laser thiab yog li ntawd tsis ruaj tsis khov.

Nyob rau hauv cov ntaub ntawv no, lub wavelength tsis muaj teeb meem.Qhov kev hloov ntawm qhov nqus cov yam ntxwv ntawm cov hlau nyob rau hauv lub wavelength ntau ntawm 400nm mus rau 10um tsis txaus los ua lub luag hauj lwm ntawm no.Qhov tseem ceeb tshaj plaws yam ntxwv yog lub reflectivity vim nto flatness thiab zoo. nrog rau qhov tsis sib xws, qhov chaw tiaj tus tuaj yeem cuam tshuam ntau lub teeb rov qab rau saum npoo.
Diode lasers yog rhiab heev rau rov qab reflections.End lub ntsej muag puas, wavelength instability, thiab beam qauv hloov tej zaum yuav tshwm sim.Faraday cais yuav siv tau los daws qhov teeb meem no.
Gas lasers (xws li CO2 lasers koom nrog ntawm no) yuav tsis puas los ntawm kev rov qab xav.Qhov tseeb, cov txheej txheem no tuaj yeem siv los ua lub hom phiaj ua Q-hloov kom ua tiav lub zog pulse ntau dua.
Tej zaum siv Nd:YAG lasers, ytterbium fiber ntau lasers lossis lasers zoo sib xws, uas feem ntau yog siv los txiav cov hlau es tsis txhob siv CO2 lasers.Ntawm cov qib qis zog ~ 50W, 10um laser los ntawm CO2 laser yog zoo absorbed los ntawm cov ntaub ntawv organic ( xws li yas), tab sis nws yuav tsis muaj kev cuam tshuam rau cov hlau.
Qhov loj me me ntawm cov khoom siv yas pib yog dab tsi?Vam tias nws yog qhov loj thiab tsis tuaj yeem sib kis hauv huab cua, vim tias yog cov khoom yas nkag mus rau hauv huab cua thiab lo rau koj daim iav, lub lens, thiab cov khoom tso tawm, koj yuav muaj hnub tsis zoo. .
Txhawm rau txo qhov xwm txheej no, cov khoom siv kho qhov muag yuav tsum raug cais tawm ntawm "qhov chaw ua haujlwm" txhawm rau tiv thaiv cov hmoov yas nkag.
Hi, just to tell you this is good news!!The company I work for, we produce and manufacture powders for SLS PA12, PA11, TPU, and polycaprolactone and waxes for sls.I really think this is the technology of the future!!If you need customized sls materials, please feel free to contact me!marga.bardeci@advanc3dmaterials.com
Kuv xav tias laser sintering pob qij txha yuav txias-tsis muaj daim ntawv xav tau! Koj puas tuaj yeem muab cov ntaub ntawv?
Zoo, kuv muab tsis tau rau koj.Qhov no
Qhov no yuav yog lub tswv yim zoo rau Netherlands
.Tab sis kuv paub tias qee cov neeg tau ua sintered ntawv, nrog rau sintered qab zib thiab nesquick.
Los ntawm kev siv peb lub vev xaib thiab cov kev pabcuam, koj pom zoo meej rau qhov kev tso kawm ntawm peb qhov kev ua tau zoo, kev ua haujlwm thiab kev tshaj tawm cov ncuav qab zib. Kawm ntxiv
