Kev pab cuam sai sai 3D printing prototyping
Cov kws tshaj lij thoob ntiaj teb tab tom siv kev ua haujlwm 3D luam ntawv txhawm rau txhim kho lawv cov txheej txheem tsim khoom hauv ntau txoj hauv kev.Feem ntau ntawm cov tuam txhab ua lag luam thoob ntiaj teb hauv engineering, kev lag luam tsheb, neeg hlau, architecture, thiab kev kho mob tau koom ua ke 3D luam ntawv rau hauv lawv cov kev ua haujlwm kom txiav cov sij hawm txhuas thiab coj rov qab tswj cov txheej txheem hauv tsev.Cov no muaj ntau yam los ntawm cov khoom prototyping ua ntej cov khoom loj, mus rau kev tsim cov khoom ua haujlwm uas tuaj yeem ua kom pom tias ib feem yuav ua haujlwm li cas.Txhawm rau pab cov tuam txhab no, PF Mould tsim thiab tsim ntau yam kev tshaj lij 3D luam ntawv daws teeb meem uas lub hom phiaj pab peb cov neeg siv khoom ua tiav cov txiaj ntsig sai dua thiab tsim cov khoom zoo tshaj plaws 3D luam tawm.
1,3D Printing Txheej txheem thiab cov txheej txheem:
Fused Deposition Modeling (FDM)
FDM yog tej zaum feem ntau siv daim ntawv ntawm 3D luam ntawv.Nws muaj txiaj ntsig zoo heev rau kev tsim cov qauv thiab qauv nrog cov yas.FDM siv cov extruded melted filament los ntawm lub nozzle los tsim cov txheej txheem los ntawm txheej.Nws muaj qhov zoo ntawm ntau yam kev xaiv cov khoom ua rau nws zoo tagnrho rau kev tsim qauv thiab siv kawg.
Stereolithography (SLA) Technology
SLA yog ib hom kev luam ntawv ceev ceev uas zoo tshaj plaws rau kev luam ntawv hauv kev nthuav dav.Lub tshuab luam ntawv siv lub laser ultraviolet los tsim cov khoom hauv ib teev.
SLA siv lub teeb rau crosslink monomers thiab oligomers los tsim cov polymers tsis zoo photochemically, txoj kev no yog tsim rau cov qauv kev lag luam, thiab kev thuam, cov qauv tsis ua haujlwm tsis zoo.
Xaiv Laser Sintering (SLS)
Ib daim ntawv ntawm Powder Bed Fusion, SLS fuses me me ntawm cov hmoov ua ke los ntawm kev siv lub zog loj laser los tsim cov duab peb sab.Lub laser scans txhua txheej ntawm lub txaj hmoov thiab xaiv fuses lawv, tom qab ntawd txo cov hmoov txaj los ntawm ib qho tuab thiab rov ua cov txheej txheem los ntawm kev ua tiav.
Lub SLS siv lub tshuab computer tswj laser los ua cov khoom siv hmoov (xws li Nylon lossis polyamide) txheej los ntawm txheej.Cov txheej txheem tsim kom raug, zoo qhov chaw uas yuav tsum tau tsawg kawg tom qab ua tiav thiab kev txhawb nqa.
2/3D Printing Khoom:
Muaj ntau yam khoom siv sib txawv uas lub tshuab luam ntawv siv los tsim cov khoom kom zoo tshaj plaws ntawm nws lub peev xwm.Nov yog qee qhov piv txwv:
ABS
Acrylonitrile Butadiene Styrene resin yog cov khoom siv mis nyuj dawb nrog rau qee qhov kev sib tw, nrog qhov ceev ntawm 1.04 ~ 1.06 g / cm3.Nws muaj zog corrosion tsis kam rau cov kua qaub, alkalis, thiab ntsev, thiab nws tuaj yeem zam cov kuab tshuaj organic rau qee yam.ABS yog cov khoom siv uas muaj cov khoom siv zoo, qhov kub thiab txias, kev ruaj ntseg zoo, tshuaj tiv thaiv, hluav taws xob rwb thaiv tsev, thiab nws yooj yim rau kev tsim khoom.
Nylon
Nylon yog ib yam khoom uas tib neeg tsim.Nrog rau txoj kev loj hlob ntawm science thiab technology, nws tau dhau los ua ib qho tseem ceeb engineering yas.Nws muaj lub zog loj heev, Zoo cuam tshuam tsis kam, lub zog, thiab toughness.Nylon kuj tseem siv tau los ua 3D cov ntaub ntawv luam tawm rau kev txhawb nqa.3D-luam nylon muaj qhov ntom ntom, thiab cov nylon yog tsim los ntawm cov hmoov laser.
PETG
PETG yog cov yas pob tshab uas muaj viscosity zoo, pob tshab, xim, tshuaj tsis haum, thiab kev ntxhov siab tsis kam rau tshuaj dawb.Nws cov khoom yog pob tshab, zoo heev cuam tshuam tsis kam, tshwj xeeb tshaj yog tsim rau kev tsim cov phab ntsa tuab pob tshab, nws cov molding kev ua tau zoo heev, tuaj yeem tsim raws li tus tsim lub hom phiaj ntawm txhua yam duab.Nws yog ib qho khoom siv 3D luam ntawv feem ntau.
PLA
PLA yog biodegradable thermoplastic nrog cov neeg kho tshuab zoo thiab kev ua haujlwm.Nws yog ib qho polymer ua los ntawm polymerization ntawm lactic acid, Feem ntau yog pob kws, cassava, thiab lwm yam ntaub ntawv raw.Polylactic acid muaj qhov zoo thermal stability, ua haujlwm kub ntawm 170 ~ 230 ℃, hnyav hnyav, tuaj yeem ua tiav ntau yam, xws li 3D luam ntawv, extrusion, spinning, biaxial stretching, txhaj tshuaj molding.
