Ososayensi baseMichigan Technology University, eHoughton benze ngempumelelo i-3D yokhuni oluphrintekayo kusuka kudoti yokhuni yefenisha.
Impumelelo ishicilelwe ephepheni locwaningo elihlanganiswe yingqwele yemithombo evulekile uJoshua Pearce.Iphepha lihlole ukuthi kungenzeka yini ukukhushulwa kwemfucuza yefenisha ibe umucu wokhuni ukuze kuncishiswe imithelela yemvelo yemfucuza yezinkuni.
Ngokwaleli phephandaba, imboni yefenisha eMichigan iyodwa ikhiqiza amathani angaphezu kuka-150 emfucumfucu yezinkuni ngosuku.
Enqubweni enezinyathelo ezine, ososayensi babonise ukuthi kungenzeka ukwenza i-3D yokuphrinta izinkuni filament ngenhlanganisela yezinkuni-imfucuza kanye nepulasitiki ye-PLA.Ingxube yalezi zinto ezimbili yaziwa kangcono ngokuthi i-wood-plastic-composite (WPC).
Esinyathelweni sokuqala, imfucuza yezinkuni yatholwa ezinkampanini ezikhiqiza ifenisha ehlukahlukene eMichigan.Imfucuza yayihlanganisa ama-slabs aqinile kanye ne-sawdust ye-MDF, i-LDF, ne-melamine.
Lawa ma-slabs aqinile kanye ne-sawdust yehliswa yaba izinga elincane ukuze kulungiswe i-WPC filament.Imfucumfucu yagaywa ngesando, yagaywa endaweni yokusika ukhuni futhi yahlungwa kusetshenziswa isisetshenziswa esidlidlizayo sokususa umoya, esasisebenzisa isisefo semeshi esingu-80-micron.
Ekupheleni kwale nqubo, imfucumfucu yokhuni yayisisesimweni esiyimpushana futhi iyingxenye ye-granular kafulawa wokusanhlamvu.Izinto manje zase zibizwa ngokuthi "i-wood-waste powder."
Esinyathelweni esilandelayo, i-PLA yayilungiselelwe ukuxuba nempushana yezinkuni.Amapellets e-PLA ayeshisiswe ku-210C aze abe namandla okunyakaziswa.I-powder yokhuni yengezwe ekuxubeni kwe-PLA encibilikisiwe ngokhuni oluhlukahlukene kuya kumaphesenti wesisindo se-PLA (wt%) phakathi kuka-10wt% -40wt% we-wood-waste powder.
Izinto eziqinile zaphinde zafakwa ku-chipper wokhuni ukuze kulungiselelwe i-open-source recyclebot, i-extruder yepulasitiki yokwenza imicu.
Umcu owenziwe wawungu-1.65mm, uzacile ngobubanzi kunomucu ojwayelekile we-3D otholakala emakethe, okungukuthi 1.75mm.
Umcu wokhuni wavivinywa ngokwakha izinto ezihlukahlukene, njengekhiyubhu lokhuni, inselelo yesicabha nesibambo sekhabethe.Ngenxa yezakhiwo zemishini ze-wood filament, ukulungiswa kwenziwe ku-Delta RepRap kanye ne-Re:3D Gigabot v. GB2 3D amaphrinta asetshenziswe ocwaningweni.Izinguquko zazihlanganisa ukulungisa i-extruder nokulawula isivinini sokuphrinta.
Ukuphrinta izinkuni ezingeni lokushisa elifanele nakho kuyisici esibalulekile njengoba izinga lokushisa eliphezulu lingashisa izinkuni futhi livale umlomo wombhobho.Kulesi simo i-wood filament yanyatheliswa ku-185C.
Abacwaningi babonisa ukuthi kwakuwusizo ukwenza i-wood filament usebenzisa imfucumfucu yezinkuni zefenisha.Nokho, baphakamise amaphuzu abalulekile esifundo esizayo.Lokhu kuhlanganisa imithelela yezomnotho nemvelo, imininingwane yezakhiwo zemishini, amathuba okukhiqizwa kwezimboni.
Leli phepha laphetha ngokuthi: “lolu cwaningo luye lwabonisa indlela yobuchwepheshe esebenzayo yokukhuculula imfucumfucu yezinkuni zefenisha ibe izingxenye eziphrintekayo eziyi-3-D embonini yefenisha.Ngokuxuba ama-pellets e-PLA kanye nemicu yemfucumfucu yokhuni egaywe kabusha yakhiqizwa enobukhulu obuyi-1.65±0.10 mm futhi isetshenziselwe ukuphrinta izinhlobonhlobo ezincane zezingxenye zokuhlola.Le ndlela ngenkathi ithuthukiswa elebhu ingase inyuswe ukuze ihlangabezane nezidingo zemboni njengoba izinyathelo zenqubo zingenzima.Kwadalwa amaqoqo amancane okhuni angu-40wt%, kodwa akhombisa ukuphindaphinda okunciphile, kuyilapho amaqoqo okhuni angu-30wt% abonisa isithembiso esisebenziseka kalula.”
Iphepha locwaningo okukhulunywe ngalo kulesi sihloko linesihloko esithi Wood Furniture Waste-based Recycled 3-D Printing Filament.Ibhalwe ngokuhlanganyela ngu-Adam M. Pringle, Mark Rudnicki, kanye noJoshua Pearce.
