Masayendisiti paMichigan Technology University, Houghton akabudirira kugadzira 3D inodhinda huni filament kubva mufenicha yehuni-marara.
Kubudirira kwakaburitswa mubepa rekutsvagisa rakanyorwa pamwe neakavhurika-sosi mhare Joshua Pearce.Bepa rakaongorora mukana wekusimudzira marara efenicha kuita filament yehuni kuderedza kukanganiswa kwezvakatipoteredza kwemarara ematanda.
Maererano nebepa, indasitiri yefenicha muMichigan chete inobudisa matani anopfuura 150 emarara ehuni pazuva.
Mune nhanho ina, masayendisiti akaratidza mukana wekugadzira 3D kudhinda huni filament nemusanganiswa wehuni-marara uye PLA plastiki.Musanganiswa wezvinhu zviviri izvi unozivikanwa zviri nani sehuni-plastic-composite (WPC).
Padanho rekutanga, tsvina yehuni yakatorwa kubva kumakambani akasiyana ekugadzira fenicha muMichigan.Tsvina yaisanganisira slabs yakasimba uye sawdust yeMDF, LDF, uye melamine.
Aya ma slabs akasimba uye sawdust akaderedzwa kusvika padiki-scale level yekugadzirira kweWPC filament.Tsvina iyi yakagayiwa nesando, yakagayiwa muhuni uye yopepetwa pachishandiswa chinozunguzirwa chekubvisa mhepo, icho chaishandisa 80-micron mesh sefa.
Pakupera kwekuita uku, tsvina yehuni yaive muhupfu ine granular constituency yehupfu hwezviyo.Izvo zvinhu zvino zvave kunzi "huni-tsvina hupfu."
Muchikamu chinotevera, PLA yakagadzirira kusanganiswa nehuni-tsvina yehuni.PLA pellets yaipisa pa210C kusvika yava kubvongodzwa-kukwanisa.Iyo huni yehuni yakawedzerwa kune yakanyungudutswa yePLA inosanganiswa nehuni yakasiyana-siyana kune PLA uremu muzana (wt%) pakati pe10wt% -40wt% huni-tsvina poda.
Iyo yakaomeswa zvinhu zvakaiswa zvakare muhuni chipper kugadzirira yakavhurika-sosi recyclebot, yepurasitiki extruder yekugadzira filament.
Iyo filament yakagadzirwa yaive 1.65mm, yakatetepa muhupamhi kupfuura yakajairwa 3D filament inowanikwa pamusika, kureva 1.75mm.
Filament yehuni yakaedzwa nekugadzira zvinhu zvakasiyana-siyana, zvakadai secube yepuranga, bhandi regonhi, uye mubato wedhirowa.Pamusana pekugadzirwa kwemagetsi ehuni filament, kugadziriswa kwakaitwa kuDelta RepRap uye Re: 3D Gigabot v. GB2 3D printers inoshandiswa muchidzidzo.Iko kushandurwa kwaisanganisira kugadzirisa extruder uye kudzora kumhanya kwekudhinda.
Kudhinda huni patembiricha yakakodzera zvakare chinhu chakakosha sezvo tembiricha yakanyanya inogona kupisa huni uye kuvhara muromo.Muchiitiko ichi filament yehuni yakadhindwa pa185C.
Vatsvakurudzi vakaratidza kuti zvaive zvinoshanda kugadzira filament yehuni uchishandisa fenicha tsvina yehuni.Nekudaro, vakasimudza pfungwa dzakakosha dzekudzidza mune ramangwana.Izvi zvaisanganisira kukanganisa kwehupfumi uye kwezvakatipoteredza, ruzivo rwemichina yezvivakwa, mukana wekugadzirwa kwemaindasitiri.
Pepanhau rakapedzisa richiti: “chidzidzo ichi chakaratidza nzira inogoneka yekukwirisa marara ematanda efenicha kuita zvikamu zvinodhindwa zve3-D zveindasitiri yefenicha.Nekusanganisa PLA pellets uye yakadzokororwa tsvina yehuni filament yakagadzirwa nehupamhi hwehupamhi hwe1.65± 0.10 mm uye yakashandiswa kudhinda mashoma akasiyana ezvikamu zvekuedza.Iyi nzira ichiri kugadzirwa mulabhu inogona kukwidziridzwa kuti isangane nezvido zveindasitiri sezvo matanho ekuita asina kuoma.Matatu madiki ehuni 40wt% akagadzirwa, asi airatidza kuderedzwa kudzokororwa, nepo mabhechi e30wt% ehuni airatidza kuvimbiswa kwakanyanya nyore kushandisa.
Bepa rekutsvagisa rinokurukurwa muchinyorwa ichi rakanzi Wood Furniture Waste-Yakavakirwa Recycled 3-D Printing Filament.Yakanyorwa pamwe chete naAdam M. Pringle, Mark Rudnicki, naJoshua Pearce.
Kuti uwane dzimwe nhau pamusoro pekuvandudzwa kwe 3D kudhinda, nyoresa kutsamba yedu yekudhinda ye 3D.Uyewo batana nesu paFacebook ne Twitter.
