Khoom Description
Peb cov kev pabcuam Multijet Fusion Printing tuaj yeem luam cov khoom siv hauv cov xim dub PA12. Cov khoom tsim los ntawm MJF nrog cov ntaub ntawv PA12 dub, feem ntau tsaus grey -dub. Tsis yog dub dawb huv. Kev sib piv rau cov dawb PA12 SLS luam tawm qhov chaw, MJF Dub PA12 qhov chaw yog me ntsis ntxhib thiab tsawg dua qhov ua siab ntev. Tab sis ntau harden thiab muaj kev cuam tshuam zoo dua. Ntawm qhov tsis sib xws, dawb PA12 hloov tau yooj yim dua.
Dab tsi yogMJF?
MJF stands rau Multi Jet Fusion, nws yog ib qho kev lag luam 3D luam ntawv thev naus laus zis tsim los ntawm HP, siv los tsim cov siab - lub zog, cov khoom yas meej (Tsuas yog Dub Nylon). Tsis zoo li SLS, uas siv lub laser los "kos" cov khoom hauv cheeb tsam taw tes -los ntawm-point, MJF fuses tag nrho cov txheej ib zaug, ua rau nws nrawm dua. Tom qab cov hmoov txheej kis tau, lub inkjet array sprays lub flux thiab refiner. Nyob rau hauv lub illumination ntawm lub teeb infrared, thaj tsam ntawm cov flux absorbs tshav kub rau fusion. Qhov chaw refining tus neeg sawv cev inhibits fusion thiab xyuas kom meej cov npoo.

MJF vs SLS (Qhov txawv tseem ceeb)
- MJF tuaj yeem tsim cov khoom qub nrog lub sijhawm ua piv txwv sai dua li SLS
- MJF luam tawm qhov chaw nrog zoo dua li SLS, nws yog smoother. SLS yuav kuj ntxhib
- MJF Cov khoom lag luam nrog kev ruaj ntseg zoo dua. Kev xaiv zoo rau kev kub siab ua haujlwm
- SLS muaj qhov zoo dua hauv kev ua kom tawv nqaij: qhov elongation ntau dua thaum tawg (txog 35% feem ntau)
- SLS luam ntawv tuaj yeem hloov tau yooj yim ntawm cov ntaub ntawv. MJF feem ntau yog rau Dub PA12.
- SLS luam tawm dawb PA12 qhov chaw tuaj yeem dye rau cov xim sib txawv
