Ngiyaqiniseka ukuthi sekwenzekile kuwe: uchithe amahora amaningi uklama iphrojekthi enkulu, njengesigqoko seqhawe noma ingxenye yezimboni, futhi ngokuzumayo uqaphela ukuthi ivolumu yokwakha yephrinta yakho ayanele. Noma okubi nakakhulu, ngemva komsebenzi wosuku lonke, lokho kugoqa kushiye isikhala esivulekile phakathi kwento yakho. Ungesabi, akusikho ukuphela komhlaba futhi akudingeki ulahle izinto. Ukwazi ukuhlanganisa izingxenye eziphrintiwe nge-3D, ngokuyisisekelo, yikhono elihlukanisa umuntu owenza izibalo ezimbalwa kumenzi weqiniso.
Abaqalayo abaningi benza iphutha lokuzama ukuphrinta konke ngesikhathi esisodwa, kodwa labo abanolwazi bayazi ukuthi ukuhlukanisa kubalulekile. Ngokuhlukanisa imodeli, ugwema ukugcwalisa ingxenye ngezisekelo ezishiya amamaki angathandeki, futhi usebenzisa isu lokulawula ubungozi : uma kukhona okungahambi kahle, uphinda uphinde uphrinte ingxenye ethintekile futhi awuchithi yonke impahla noma isikhathi. Ngaphezu kwalokho, ukuhlukanisa kukuvumela ukuthi uzame ukuxubana kwezinto, usebenzisa i-PETG yesakhiwo kanye ne -TPU yezindawo eziguquguqukayo , okuholela ezintweni ezisebenzayo ezingenakwenzeka ukukhiqiza ngokuphrinta okukodwa.
Umlingo wekhemistri: Ukuhlanganisa nokuhlanganisa ama-polymer
Ukuze kugcinwe izingcezu ezimbili ndawonye, ukuzicindezela ngokuqinile ngeke kusebenze; okubalulekile ukuthi isinyibilikisi kanye nepulasitiki kuhlangana kahle ezingeni lama-molecule. Akuzona zonke izinti ezinamathelayo ezingena ngaphakathi; ezinye zihlala phezu kobuso bese ziqhekeka ekugcineni.
- Amalunga e-PLA: I-Cyanoacrylate iyinkosi lapha. Iyashesha futhi iqinile, ilungele imininingwane emincane. Qaphela nje ukuthi ayiqhakazi (lawo mabala amhlophe angabukeki kahle); ikhambi liwukufaka umoya kahle noma usebenzise i-spray activator ukuqinisekisa ukubopha okuqinile. ngokushesha nangokucacile.
- Icebo le-ABS: Le nto iyamangalisa ngoba iyancibilika ku-acetone. Indlela engcono kakhulu yokuyenza ukukhiqiza i-"ABS Slurry," ehilela ukuncibilikisa izinsalela ze-filament ku-acetone emsulwa kuze kube yilapho kudalwe unamathisela ofana noju. Uma kusetshenziswa, izingcezu zihlangana ngokoqobo zibe yisakhiwo esisodwa, zidale isibopho esiqinile njengezinto zokuqala.
- Inselele ye-PETG nezinto zobuchwepheshe: La mapulasitiki anamandla aphansi ebusweni, okwenza inhlaka "ishelele." Kulezi zimo, kungcono ukusebenzisa i-thermal fusion noma i-mechanical assembly ukuvimbela ingxenye ukuthi ingaphumeleli ngenxa yalokhu. ukukhathala okunamathelayo ngenxa yokushintsha kwezinga lokushisa.
Ukushisela okushisa: Uma iglue inganele
Uma ingxenye yakho izobhekana nokucindezeleka kwangempela komshini noma ivezwe ezintweni, kungcono ukuyincibilikisa kabusha ipulasitiki ukuze amaketanga e-polymer aphinde axhumane. Lena yindlela ephephile yokuqinisekisa ukuthi ngeke ihlukane.
Ithuluzi elibalulekile ipeni le-3D, elisebenza njenge-extruder ephathwayo. Lilungele ukugcwalisa izikhala nokushisela imifantu ejulile usebenzisa izinto ezifanayo nombala ofana nengxenye. Uma seyomile, ukushefa kancane bese umthungo uyanyamalala. Uma ungenayo ipeni le-3D, ungasebenzisa i-friction welding: faka ucezu lwe-filament ku-Dremel ku-20.000 RPM bese uluthinta ejoyintini. Ukushisa okuvela ekushiseni kuncibilikisa yonke into ngokushesha; kuyindlela engacacile, kodwa isebenza kahle kakhulu kumaphaneli amakhulu noma ifenisha.
Imihlangano yemishini kanye nomklamo ohlakaniphile
Amanye amaphrojekthi adinga ukulungiswa noma kumele amelane nokudlidliza okunamandla, njengenjini ye-kayak. Kulezi zimo, indlela ehlakaniphile kakhulu ukuklama ijoyinti kusetshenziswa isofthiwe ye-CAD ukuqinisekisa ukuxhumana okungokoqobo kunokuthembela esibophweni samakhemikhali.
- Izinto zokufaka ezishisayo: Khohlwa ngokufaka isikulufu ngqo kupulasitiki; izokhumula ekuswayipheni kokuqala. Izingcezu zethusi zicindezelwa ngensimbi yokunamathisela, okudala intambo yangempela yensimbi. Yiyo indinganiso yobungcweti yama-drone kanye nezimbobo ze-elekthronikhi.
- Amabhrasi ahlukahlukene: Ungasebenzisa izikulufo zokuzithinta ezintweni ezilula, noma amabhawodi anamantongomane emithwalo esindayo. Ama-rivethi alungele izingxenye ezincane, yize kufanele uqaphele ukuthi ungawachobozi amapulasitiki.
- Izinhlelo zokulinganisa i-Snap: Lawa amathebhu "achofozayo". Adinga ukubekezela okuhle (ngokuvamile ashiya cishe u-0.2 mm wesikhala), kodwa ayinketho ehlanzekile nenhle kakhulu.
- Amalunga esakhiwo: Ngefenisha noma ozimele, amajoyinti e-dovetail noma amajoyinti e-mortise kanye ne-tenon awahlulwa, njengoba enikeza ukuzinza okuphezulu kwemishini ngaphandle kwesidingo samathuluzi angaphandle.
Ukusetshenziswa kwezinto kanye nokuqedwa kokugcina
Ukuze ugweme ukugcwala indlu yakho ngama-filament spools aqediwe uhhafu, ungenza umshini wokushisela i-filament owenziwe ekhaya ngebhulokhi ye-aluminium. Imfihlo iwukuncibilikisa iziphetho bese uzidlulisa ngethubhu le-PTFE ngenkathi zishisa ukuze zigcine ububanzi obungu-1.75 mm futhi kuvimbele iphrinta ukuthi ingaboni ijoyinti.
Uma ufuna ucezu lwakho lubukeke lungokwemvelo, hhayi njengoba lwalunyatheliswe nge-3D, ukucutshungulwa ngemuva kubalulekile. Uma kunemifantu engathandeki, sebenzisa i-sandpaper enemibala egqamile (80-120 grit) bese uyigcwalisa nge-polyester putty noma ingxube ye-cyanoacrylate kanye ne-baking soda ukuze uqedele ukuqina kwetshe. Bese uhlanza ngezigaba ezilandelanayo (240, 400, kanye ne-600 grit wet/dry paper) bese ufaka i- filler primer . Lokhu kuzokunikeza ukuqeda okufana nesibuko lapho imigqa yomthungo ingabonakali khona ngokuthintwa kanye neso.
Ukwazi kahle lawa masu kukuvumela ukuthi usuke ekwenzeni izinto zepulasitiki ezilula uye ekukhiqizeni imikhiqizo yangempela, eqinile. Isihluthulelo ukukhetha indlela ngokwezidingo zakho: i-cyanoacrylate yokwenza i-prototyping esheshayo, ukushisela okushisayo ukuze kutholakale amandla, kanye nomklamo wemishini ukuze kusebenze kahle, ucabangela njalo ukuhambisana kwe-polymer kanye nesikhathi sokuqeda.
