Njengomfundi we-PhD eNyuvesi yaseFlorida enza izifundo zobunjiniyela beMechanical mkhakha wokulawula, u-Tim Elmore usezozamazamisa ikusasa lemicu yephrinta ye-3D. Okwamanje, i-spool yombala wakho oyintandokazi we-ABS (noma i-PLA noma i-PVA) isebenza eningizimu nje yama-$50 esitolo se-MakerBot, ingafaki izindleko zokuthumela ezilinganiselwa ku-$12. Ebona ukuthi lokhu kungabakhungathekisa kanjani abasebenzisi abaningi bephrinta ye-3D, waqala ukwakha umshini wakhe wokwenza i-filament, I-Filastruder, esebenzisa ama-pellets epulasitiki ashibhile kanye nombala wakho siqu ukuze kukhiqizwe i-spool of filament efanayo ngemali engaphansi kwe-$10. Ukukhiqizwa kwefilament eceleni, ungacabanga ukuthi kumele kube mnandi kangakanani le nto ukuyibuka?

I-Filastruder

Nakuba abanye bezame ukwakha imishini ekhiqiza i-filament, kubukeka sengathi u-Tim kube nguyena odale umkhiqizo wokugcina ohlanzekile ngosizo lwabahloli be-beta abangu-16. Umshini usebenza ngokudayela izinga lokushisa elibekiwe ukuze ukhiphe ama-pellets epulasitiki, ulayishe i-hopper encane enamapulangwe epulasitiki nombala, bese uvele uvule i-gearmotor. Uma i-extruder isishise ngokwanele izoqala ukukhipha umkhiqizo wokugcina we-filament, ongahlanganiswa futhi usetshenziswe njenganoma iyiphi enye indinganiso yephrinta ye-3D.

Iningi labahloli be-beta basebenzise i-1.75mm filament (efanayo ne-MakerBot) kanye nokwehluka okubikiwe okucishe kube ngu-+/-0.05 mm, nokho umshini ungasetha futhi ukuze udale i-filament efika ku-3.0 mm ngokuhluka okubikiwe okucishe kube ngu-+/-0.10 mm. . Ngemva kokungena yena mathupha amahora angu-250 angenazinkinga ekhipha i-ABS, kanye nabahloli bakhe be-beta bangena amahora amaningi emishinini yabo, u-Tim uthathe konke ayekwazi ngokunyathelisa kwe-3D, wacwenga i-Filastruder, wayeseyivula. I-Kickstarter evikini eledlule:

Ekwindla ka-2012, ngathenga i-Solidoodle 2 Pro, futhi ngaqala ukuzama ukuphrinta kwe-3D. Nakuba ngangijatshuliswa ikhono elisha lokuletha umcabango ube ngokoqobo esikhathini esingaphansi kosuku, ngadumala ngendlela engangishesha ngayo ukudabula i-filament - umqulu noma amabili ngenyanga. Ngaleso silinganiso, ngaphansi konyaka bengizochitha imali eningi kupulasitiki kunezindleko zokuphrinta! Kungaleso sikhathi lapho nganquma khona ukwenza i-filament extruder.

Ngiqale ngenza inhlolovo yemakethe, ngathola i-RecycleBot, i-Filabot, i-Lyman's Filament Extruder (CC BY-SA), kanye neminye imizamo engaphelele yokukhiqiza i-pellets ukuze i-filament extruder. Ngenxa yokuthi ekaLyman kwakungeyakamuva kakhulu, ngazama ukufunda ekwakhiweni kwakhe, futhi ngacwenga izinto ukuze kube lula ukukhiqiza ngaphandle kwamathuluzi omshini, ephephile, ehlangene kakhudlwana, futhi $200 noma ngaphansi. Ngigcine ngokugcina izingxenye ezintathu ekwakhiweni kwakhe - i-auger, i-bearing, kanye nombhobho.

NgoNovemba, ngakha inguqulo ye-alpha yalokho okwakuzoba i-Filastruder. Ngibe nemiphumela emihle, kodwa ngalungisa idizayini futhi ngaqala ukucela abahloli be-beta. NgoDisemba, ngathumela ama-beta kits kubantu abangu-4. Ngempendulo yabo, ngilungise idizayini futhi, ngabathumela amakhithi okuthuthukisa, futhi ngathumela amakhithi engeziwe angu-12 kubahloli be-beta emhlabeni jikelele. Kusukela ngoJanuwari kuze kube manje, labo bahloli be-beta bebesebenza ne-Filastruder.

Njengoba cishe u-$150,000 woxhaso (lokho kungu-$145,000 ngaphezu komgomo wakhe wokuqala), kanye nezinsuku ezingu-21 ukuthi kuqhubeke i-Kickstarter, u-Tim usendleleni eya enkazimulweni ye-filament-bustin'.
