Ua hana maikaʻi nā kānaka ʻepekema ma ke Kulanui ʻenehana ʻo Michigan, Houghton i ka filament lāʻau hiki ke paʻi ʻia 3D mai nā ʻōpala lāʻau hale.
Ua paʻi ʻia ka kūleʻa ma kahi pepa noiʻi i kākau pū ʻia e ka poʻokela open-source ʻo Joshua Pearce.Ua ʻimi ka pepa i ka hiki ke hoʻonui i ka ʻōpala o nā lako i loko o ka filament lāʻau e hōʻemi i ka hopena o ka ʻōpala lāʻau.
Wahi a ka pepa, ʻo ka ʻoihana mea hale ma Michigan wale nō ka mea e hana ai ma mua o 150 tons o ka ʻōpala wahie i ka lā.
Ma kahi kaʻina hana ʻehā, ua hōʻike nā ʻepekema i ka hiki ke hana i ka filament lāʻau paʻi 3D me ka hui pū ʻana o ka ʻōpala lāʻau a me ka plastic PLA.ʻOi aku ka maikaʻi o ka hui ʻana o kēia mau mea ʻelua ʻo ka wood-plastic-composite (WPC).
I ka hana mua, ua loaʻa ka ʻōpala wahie mai nā ʻoihana hana hale ʻokoʻa ma Michigan.Aia i loko o ka ʻōpala nā papa paʻa a me ka ʻōpala o MDF, LDF, a me ka melamine.
Ua hoʻemi ʻia kēia mau papa paʻa a me ka sawdust i ka pae micro-scale no ka hoʻomākaukau ʻana i ka filament WPC.Ua wili ʻia ka ʻōpala i ka hāmare, i kāwili ʻia i loko o kahi ʻāpana lāʻau a kānana ʻia me kahi mea hoʻoheheʻe vibratory, i hoʻohana i kahi kānana mesh 80-micron.
I ka pau ʻana o kēia kaʻina hana, aia ka ʻōpala wahie i loko o kahi ʻano pauda me kahi ʻāpana ʻāpana o ka palaoa palaoa.Ua kapa ʻia ka mea i kēia manawa ʻo "ka pauka ʻōpala lāʻau."
I ka pae aʻe, ua mākaukau ʻo PLA e hui pū me ka pauka ʻōpala lāʻau.Hoʻomaʻamaʻa ʻia nā pellets PLA ma 210C a hiki i ka hiki ke hoʻoulu.Hoʻohui ʻia ka pauda lāʻau i ka hui PLA i hoʻoheheʻe ʻia me ka lāʻau like ʻole i ka pākēneka kaumaha PLA (wt%) ma waena o 10wt% -40wt% pauda ʻōpala lāʻau.
Hoʻokomo hou ʻia ka mea paʻa i loko o ka ʻōpala lāʻau e hoʻomākaukau ai no ka recyclebot open-source, kahi extruder plastic no ka hana filament.
ʻO ka filament i hana ʻia he 1.65mm, ʻoi aku ka lahilahi o ke anawaena ma mua o ka filament 3D maʻamau i loaʻa ma ka mākeke, ʻo ia hoʻi 1.75mm.
Ua hoʻāʻo ʻia ka filament lāʻau ma o ka hana ʻana i nā mea like ʻole, e like me ka pahu lāʻau, ka puʻupuʻu puka, a me ka lima huki.Ma muli o nā ʻano mechanical o ka filament lāʻau, ua hoʻololi ʻia nā mea paʻi Delta RepRap a me Re: 3D Gigabot v. GB2 3D i hoʻohana ʻia ma ke aʻo ʻana.ʻO nā hoʻololi i hoʻololi ʻia i ka extruder a me ka hoʻomalu ʻana i ka wikiwiki o ka paʻi.
He mea koʻikoʻi ke paʻi ʻana i ka lāʻau ma kahi wela kūpono no ka mea hiki i ka wela kiʻekiʻe ke ʻā i ka lāʻau a hoʻopaʻa i ka nozzle.I kēia hihia, ua paʻi ʻia ka filament wahie ma 185C.
Ua hōʻike ka poʻe noiʻi he hiki ke hana i ka filament lāʻau me ka hoʻohana ʻana i ka ʻōpala lāʻau.Eia naʻe, ua hāpai lākou i nā kumu nui no ka noiʻi e hiki mai ana.ʻO kēia mau mea i pili i ka hopena o ka hoʻokele waiwai a me ke kaiapuni, nā kikoʻī o nā waiwai mechanical, ka hiki ke hana i ka ʻoihana ʻenehana.
Ua hoʻopau ka pepa: "ua hōʻike kēia haʻawina i kahi ʻano hana ʻenehana no ka hoʻonui ʻana i nā ʻōpala lāʻau i loko o nā ʻāpana 3-D hiki ke paʻi ʻia no ka ʻoihana lako.Ma ka hui ʻana i nā pellets PLA a me nā filament mea ʻōpala lāʻau i hana hou ʻia me ka nui o ke anawaena o 1.65±0.10 mm a hoʻohana ʻia e paʻi i nā ʻāpana hoʻāʻo liʻiliʻi.Hiki ke hoʻonui ʻia kēia ʻano hana i ka wā i kūkulu ʻia ai i loko o ka lab no ka hoʻokō ʻana i nā pono ʻoihana no ka mea ʻaʻole paʻakikī ke kaʻina hana.Ua hana ʻia nā ʻāpana liʻiliʻi o 40wt% lāʻau, akā ua hōʻike ʻia ka hoʻihoʻi hou ʻana, ʻoiai nā pūʻulu o 30wt% lāʻau i hōʻike i ka ʻōlelo hoʻohiki me ka maʻalahi o ka hoʻohana.
ʻO ka pepa noiʻi i kūkākūkā ʻia ma kēia ʻatikala ʻo ia ke poʻo inoa ʻo Wood Furniture Waste-Based Recycled 3-D Printing Filament.Ua kākau pū ʻia e Adam M. Pringle, Mark Rudnicki, a me Joshua Pearce.
No ka nūhou hou aku e pili ana i ka hoʻomohala hou ʻana i ka paʻi 3D, e kākau inoa i kā mākou nūpepa paʻi 3D.E hui pū me mākou ma Facebook a me Twitter.
