Abashakashatsi bo muri kaminuza y’ikoranabuhanga ya Michigan, Houghton bakoze neza amashusho ya 3D yandikwa mu biti byo mu nzu.
Intsinzi yasohotse mu mpapuro z'ubushakashatsi zanditswe na nyampinga ufungura isoko Joshua Pearce.Uru rupapuro rwasuzumye uburyo bwo kuzamura imyanda yo mu nzu ikozwe mu biti kugira ngo bigabanye ingaruka z’ibidukikije ku myanda y’ibiti.
Nk’uko iyi mpapuro ibigaragaza, inganda zo mu nzu muri Michigan zonyine zitanga toni zirenga 150 z’imyanda y’ibiti ku munsi.
Mubikorwa byintambwe enye, abahanga berekanye ko bishoboka gukora 3D icapiro ryibiti bya firime hamwe n imyanda yimbaho na plastike ya PLA.Uruvange rw'ibi bikoresho byombi ruzwi cyane nk'ibiti-bya pulasitiki-bigize (WPC).
Mu ntambwe yambere, imyanda yinkwi yabonetse mumasosiyete atandukanye akora ibikoresho byo muri Michigan.Imyanda yarimo ibisate bikomeye hamwe nigiti cya MDF, LDF, na melamine.
Ibi bisate bikomeye hamwe nigiti cyaragabanutse kugera kuri micro-nini yo gutegura filament ya WPC.Ibikoresho by'imyanda byasya inyundo, bigashyirwa mu mbaho zikozwe mu giti hanyuma bikayungurura hakoreshejwe igikoresho cyo kunyeganyega, cyakoreshaga icyuma cya micron 80.
Iyo gahunda irangiye, imyanda yinkwi yari mumashanyarazi hamwe nintungamubiri yifu yifu.Ibikoresho noneho byiswe “ifu-imyanda.”
Mu ntambwe ikurikiraho, PLA yari yiteguye kuvanga nifu y-imyanda.Pelletes za PLA zashyutswe kuri 210C kugeza zimaze gukurura.Ifu yinkwi yongewe kumashanyarazi ya PLA yashonze hamwe nibiti bitandukanye kurwego rwa PLA (wt%) hagati ya 10wt% -40wt% ifu y-imyanda.
Ibikoresho bikomeye byongeye gushyirwa muri chipper yimbaho kugirango bitegure gufungura-reyclebot, isoko ya plastike yo gukora filament.
Filament yahimbwe yari 1,65mm, inanutse ya diametero kurenza filime isanzwe ya 3D iboneka ku isoko, ni ukuvuga 1.75mm.
Filament yimbaho yageragejwe muguhimba ibintu bitandukanye, nka cube yimbaho, urugi rwumuryango, hamwe nicyuma gikurura.Bitewe nubukanishi bwimiterere yibiti, hahinduwe ibya Delta RepRap na Re: 3D Gigabot na GB2 icapiro rya 3D ryakoreshejwe mubushakashatsi.Guhindura harimo guhindura extruder no kugenzura umuvuduko wo gucapa.
Gucapa ibiti ku bushyuhe bwiza nabwo ni ikintu cyingenzi kuko ubushyuhe bwo hejuru bushobora gutwika inkwi no gufunga nozzle.Muri iki gihe, filament yimbaho yacapishijwe 185C.
Abashakashatsi berekanye ko ari byiza gukora filament yimbaho ukoresheje imyanda yo mu nzu.Ariko, bazamuye ingingo zingenzi zo kwiga ejo hazaza.Harimo ingaruka zubukungu n’ibidukikije, ibisobanuro birambuye kumiterere yubukanishi, ibishoboka ko umusaruro uva mu nganda.
Uru rupapuro rwanzuye ruti: “ubu bushakashatsi bwerekanye uburyo bwa tekiniki bwo kuzamura imyanda y'ibiti byo mu nzu mu bice 3-D byifashishwa mu gucapa ibikoresho byo mu nzu.Mu kuvanga pelletes za PLA hamwe nibisubirwamo byimyanda yimbaho yimbaho yakozwe hifashishijwe ubunini bwa diameter ingana na 1,65 ± 0,10 mm kandi ikoreshwa mugucapisha uduce duto twibizamini.Ubu buryo mugihe bwatejwe imbere muri laboratoire burashobora kwagurwa kugirango buhuze ibikenewe mu nganda kuko intambwe zikorwa zitoroshye.Hakozwe uduce duto twibiti 40wt%, ariko twerekanye ko byagabanutse, mugihe ibiti 30wt% byerekanaga amasezerano menshi byoroshye gukoresha. ”
Urupapuro rwubushakashatsi rwaganiriweho muriyi ngingo rwiswe ibikoresho byo mu nzu bikozwe mu myanda ishingiye ku bicuruzwa 3-D byo gucapa.Yanditswe na Adam M. Pringle, Mark Rudnicki, na Joshua Pearce.
Kumakuru menshi yiterambere rigezweho mugucapisha 3D, iyandikishe kumakuru yacu yo gucapa 3D.Twiyunge natwe kuri Facebook na Twitter.
