Cov kws tshawb fawb ntawm Michigan Technology University, Houghton tau ua tiav 3D printable ntoo filament los ntawm rooj tog ntoo-pov tseg.
Qhov kev vam meej tau luam tawm nyob rau hauv ib daim ntawv tshawb fawb co-sau los ntawm qhib qhov chaw yeej Joshua Pearce.Daim ntawv tshawb fawb txog qhov muaj peev xwm ntawm upcycling rooj tog pov tseg rau hauv ntoo filament kom txo tau qhov cuam tshuam ib puag ncig ntawm cov ntoo pov tseg.
Raws li daim ntawv, kev lag luam rooj tog hauv Michigan ib leeg tsim ntau tshaj 150 tons ntawm ntoo-khoom noj khoom haus ib hnub.
Hauv cov txheej txheem plaub-kauj ruam, cov kws tshawb fawb pom tau tias muaj peev xwm ua 3D luam ntawv ntoo filament nrog kev sib xyaw ntawm ntoo-khoom pov tseg thiab PLA yas.Kev sib xyaw ntawm ob cov ntaub ntawv no zoo dua lub npe hu ua ntoo-yas-composite (WPC).
Hauv thawj kauj ruam, cov khib nyiab ntoo tau txais los ntawm ntau lub tuam txhab tsim rooj tog hauv Michigan.Cov khib nyiab suav nrog cov slabs thiab sawdust ntawm MDF, LDF, thiab melamine.
Cov khoom slabs thiab sawdust tau txo qis rau qib micro-scale rau kev npaj ntawm WPC filament.Cov khoom pov tseg yog rauj milled, hauv av hauv cov ntoo chipper thiab sifted siv lub vibratory de-airing ntaus ntawv, uas siv 80-micron mesh sifter.
Thaum kawg ntawm cov txheej txheem no, cov khib nyiab ntoo yog nyob rau hauv cov hmoov nplej nrog ib tug granular constituency ntawm cov hmoov nplej.Cov khoom siv tam sim no hu ua "wood-khoom hmoov."
Hauv cov kauj ruam tom ntej, PLA tau npaj los sib xyaw nrog cov hmoov ntoo-kua pov tseg.PLA pellets tau ua kom sov ntawm 210C kom txog thaum lawv ua tau zoo.Cov hmoov ntoo tau ntxiv rau cov PLA melted sib tov nrog cov ntoo sib txawv rau PLA qhov hnyav feem pua (wt%) ntawm 10wt% -40wt% ntoo-khoom hmoov.
Cov khoom siv khov kho tau rov muab tso rau hauv cov ntoo chipper los npaj rau qhov qhib qhov chaw recyclebot, yas extruder rau filament ua.
Cov filament fabricated yog 1.65mm, thinner nyob rau hauv txoj kab uas hla tshaj tus qauv 3D filament muaj nyob rau hauv lub lag luam, piv txwv li 1.75mm.
Cov ntoo filament tau sim los ntawm kev tsim ntau yam khoom, xws li lub voos xwmfab ntoo, lub qhov rooj, thiab lub tub rau khoom.Vim yog cov khoom siv ntawm cov ntoo filament, kev hloov kho tau ua rau Delta RepRap thiab Re: 3D Gigabot v. GB2 3D printers siv hauv txoj kev kawm.Cov kev hloov pauv suav nrog kev hloov kho lub extruder thiab tswj qhov nrawm ntawm kev luam tawm.
Kev luam ntawv ntoo ntawm qhov zoo tagnrho kub kuj yog qhov tseem ceeb vim tias qhov kub siab tuaj yeem ua rau cov ntoo thiab txhaws lub nozzle.Hauv qhov no, cov ntaub ntawv ntoo tau luam tawm ntawm 185C.
Cov kws tshawb fawb tau pom tias nws yog qhov ua tau los ua cov ntaub ntoo siv cov rooj tog ntoo pov tseg.Txawm li cas los xij, lawv tau tsa cov ntsiab lus tseem ceeb rau kev kawm yav tom ntej.Cov no suav nrog kev lag luam thiab kev cuam tshuam ib puag ncig, cov ntsiab lus ntawm cov khoom siv kho tshuab, muaj peev xwm ntawm kev tsim khoom lag luam.
Daim ntawv xaus lus: "Qhov kev tshawb fawb no tau qhia txog kev siv tau zoo ntawm kev siv cov rooj tog zaum ntoo pov tseg rau hauv 3-D printable qhov chaw rau kev lag luam rooj tog.Los ntawm kev sib xyaw PLA pellets thiab rov siv cov khoom pov tseg ntoo filament tau tsim nrog txoj kab uas hla ntawm 1.65 ± 0.10 hli thiab siv los luam ntau yam me me ntawm cov khoom xeem.Txoj kev no thaum tsim nyob rau hauv lub chaw kuaj ntshav yuav raug ntsuas kom tau raws li kev lag luam xav tau vim tias cov txheej txheem txheej txheem tsis nyuaj.Cov khoom me me ntawm 40wt% ntoo tau tsim, tab sis pom tias txo qis rov ua dua, thaum cov khoom siv ntawm 30wt% ntoo pom qhov kev cog lus tshaj plaws nrog kev siv yooj yim. "
Cov ntawv tshawb fawb tau tham hauv tsab xov xwm no yog hu ua Wood Furniture Waste-Based Recycled 3-D Printing Filament.Nws yog tus sau los ntawm Adam M. Pringle, Mark Rudnicki, thiab Joshua Pearce.
