Iingcali zenzululwazi kwiYunivesithi yaseMichigan Technology, eHoughton zenze ngempumelelo i-3D i-filament yokhuni eprintwayo kwifenitshala yokhuni-inkunkuma.
Impumelelo yapapashwa kwiphepha lophando elibhalwe ngokubambisana yintshatsheli yomthombo ovulekileyo uJoshua Pearce.Iphepha liphonononge ukuba nokwenzeka kokunyusa inkunkuma yefenitshala ibe yimisonto yomthi ukunciphisa iimpembelelo zokusingqongileyo zenkunkuma yomthi.
Ngokutsho kwephepha, ishishini lefenitshala eMichigan lilodwa livelisa ngaphezu kweetoni ezili-150 zenkunkuma yomthi ngosuku.
Kwinkqubo yamanyathelo amane, izazinzulu zibonise ukuba kunokwenzeka ukwenza i-3D yoshicilelo lwe-wood filament kunye nokudibanisa kwenkunkuma yomthi kunye ne-PLA yeplastiki.Umxube wezi zixhobo zimbini waziwa ngcono njenge-wood-plastic-composite (WPC).
Kwinyathelo lokuqala, inkunkuma yeenkuni yafunyanwa kwiinkampani ezahlukeneyo zokwenza ifanitshala eMichigan.Inkunkuma yayiquka amacwecwe aqinileyo kunye nothuli lwe-MDF, i-LDF, kunye ne-melamine.
Ezi slabs ziqinileyo kunye ne-sawdust zancitshiswa kwinqanaba elincinci lokulungiswa kwe-WPC filament.Inkunkuma yayicolwa ngehamile, yagutywa ngentsimbi yenkuni yaze yahluzwa kusetyenziswa isixhobo sokungcangcazela sokukhupha umoya, esasebenzisa isisefo se-80-micron mesh.
Ekupheleni kwale nkqubo, inkunkuma yeenkuni yayikwimo yomgubo kunye ne-granular constituency yomgubo wengqolowa.Izinto ngoku zazibizwa ngokuba “ngumgubo wenkunkuma yomthi.”
Kwinqanaba elilandelayo, i-PLA yayilungiselelwe ukuxuba kunye ne-powder-waste powder.Iipellets ze-PLA zafudunyezwa kwi-210C de zakwazi ukushukuma.Umgubo womthi wongezwa kumxube we-PLA onyibilikisiweyo kunye neenkuni ezahlukeneyo ukuya kwipesenti yobunzima be-PLA (wt%) phakathi kwe-10wt% -40wt% yomgubo wenkunkuma yomthi.
Izinto eziqinileyo zaphinda zafakwa kwi-wood chipper ukulungiselela i-open-source recyclebot, i-plastic extruder yokwenza i-filament.
I-Filament eyenziweyo yayiyi-1.65mm, incinci ngobubanzi kune-filament ye-3D eqhelekileyo ekhoyo kwimarike, okt 1.75mm.
Umcu womthi wavavanywa ngokwenza izinto ezahlukahlukeneyo, njengetyhubhu eyenziwe ngomthi, iqhiya locango, nomqheba wedrowa.Ngenxa yeempawu zemishini ye-filament yokhuni, uhlengahlengiso lwenziwe kwi-Delta RepRap kunye ne-Re: 3D Gigabot v. GB2 3D abashicileli abasetyenziswe kwisifundo.Utshintsho lubandakanya ukuguqula i-extruder kunye nokulawula isantya soshicilelo.
Ukuprinta iinkuni kwiqondo lobushushu elifanelekileyo ikwayinto ebalulekileyo njengoko ubushushu obuphezulu bunokutshisa iinkuni kwaye buvale umlomo.Kule meko i-filament yomthi yaprintwa kwi-185C.
Abaphandi babonise ukuba kwakunokwenzeka ukwenza i-filament yomthi usebenzisa inkunkuma yomthi wefenitshala.Nangona kunjalo, baphakamise iingongoma ezibalulekileyo kwisifundo sexesha elizayo.Oku kuquka iimpembelelo zoqoqosho kunye nokusingqongileyo, iinkcukacha zezakhiwo zoomatshini, ukuba nokwenzeka kokuveliswa kwemveliso.
Eli phepha laqukumbela ngelithi: “olu phononongo luye lwabonisa indlela enobugcisa yokunyusa inkunkuma yamaplanga efanitshala ibe ziindawo eziprintwayo eziyi-3-D kushishino lwefenitshala.Ngokuxuba iipeliti ze-PLA kunye ne-filament yenkunkuma yomthi esetyenzisiweyo yaveliswa enobukhulu obuyi-1.65±0.10 mm kwaye isetyenziselwa ukuprinta iindidi ezincinci zovavanyo.Le ndlela ngelixa iphuhlisiwe kwilebhu inokunyuswa ukukhawulelana neemfuno zeshishini njengoko amanyathelo enkqubo engantsonkothanga.Iibhetshi ezincinci ze-40wt% zomthi zenziwe, kodwa zabonisa ukuphinda-phinda okucuthiweyo, ngelixa iibhetshi ze-30wt% zokhuni zibonise esona sithembiso ngokulula ngokusetyenziswa. "
Iphepha lophando ekuxoxwe ngalo kweli nqaku linesihloko esithi Wood Furniture Waste-Based Recycled 3-D Printing Filament.Ibhalelwe nguAdam M. Pringle, uMark Rudnicki, kunye noJoshua Pearce.
Ukuze ufumane iindaba ezingakumbi ngophuhliso lwamva nje lwe-3D yoshicilelo, bhalisa kwincwadana yethu yoshicilelo ye-3D.Zidibanise nathi kuFacebook nakuTwitter.
