Uma usanda kufika ezweni elithakazelisayo lokuphrinta kwe-3D, kungenzeka ukuthi ubhekene nenkinga yakudala: yiziphi izinto okufanele uzithenge? Ekuqaleni, cishe wonke umuntu uqala nge-PLA ngoba yiyona enconywa yonke indawo, kodwa kufika isikhathi lapho uqaphela khona lokho Amaphrojekthi akho adinga okunye okwengeziwe. kunesiqephu esihle esilula esigoba ngokushisa.
Ukukhetha phakathi kwe-PETG ne-PLA akuyona indaba yokuthi yikuphi okungcono kakhulu, kodwa umbuzo wokuthi yikuphi okungcono kakhulu. Yini ofuna ukuyenza?Nakuba enye iyinkosi yobuhle nobulula, enye iyisisebenzi salezo zinto okumele zikwazi ukumelana nokuguga nokuphila kwansuku zonke, ikakhulukazi uma zizovezwa elangeni noma kumakhemikhali.
Ukuhlaziywa Okuningiliziwe kwe-PLA: Okuthandwa Ngumqali
I-PLA, noma i-polylactic acid, iyi-polymer etholakala emithonjeni yemvelo njengomoba noma ummbila, okwenza kube yinto iyabola futhi inobungani nemveloKunoma ubani oqalayo, kuyisinqumo esinengqondo ngoba kulula kakhulu ukusifunda futhi akudingi ukucushwa komshini okuyinkimbinkimbi.
Enye yezimfanelo zayo ezinhle kakhulu ukuthi awudingi umbhede ofudumele Isebenza kahle kakhulu, yize ukuyisebenzisa kungasiza. Ngaphezu kwalokho, iqiniso lokuthi ayikhiphi iphunga elinamandla (ngezinye izikhathi iphunga elimnandi kancane) lenza kube kuhle kakhulu ukuphrinta emakamelweni angenawo umoya wokungenisa umoya wezimboni, uma nje ifasitela ligcinwa livulekile ukuze kujikelezwe umoya.
Ngokuphathelene nekhwalithi yokubuka, i-PLA ayinqobeki. Inikeza imiphetho echazwe kakhulu kanye nokunemba okuhle kakhulu kobukhulu, okwenza kube kuhle kakhulu kwizithombe ze-cosplay, i-prototyping esheshayo, noma kunoma iyiphi into lapho ubuhle bubaluleke kakhulu khona. Ngaphezu kwalokho, kunezinhlobonhlobo eziningi zemibala kanye nezintambo ezikhethekile ezitholakalayo, njengalezo ezilingisa ukhuni, imabula, noma insimbi.
Kodwa-ke, inobuthakathaka obucacile kakhulu: ukumelana okuphansi kokushisaUma ushiya ingxenye ye-PLA kudeshibhodi yemoto yakho maphakathi no-Agasti, cishe izogoba, njengoba iqala ukuthamba cishe ku-60°C. Akuyona futhi inketho engcono kakhulu yezingxenye ezidinga ukumelana nokucindezeleka okuqhubekayo komshini ngaphandle kokuphuka.
Ukuthola i-PETG: Amandla kanye nokuguquguquka kobuchwepheshe
I-PETG (i-Polyethylene Terephthalate Glycol) empeleni iyindawo ephakathi nendawo phakathi kokulula kokusetshenziswa kwe-PLA nokuqina kwe-ABS. Kungashiwo ukuthi ihlanganisa okuhle kakhulu kuyo yomibili imihlabaukuhlinzeka ngomthelela kanye nokumelana nokuguquguquka okuphakeme kakhulu kunokwe-PLA.
Ngokungafani nomzala wayo olula, i-PETG idinga amazinga okushisa aphezulu okukhipha, ngokuvamile aphakathi kuka-230 no-260 °C, futhi ayidingi uketshezi oluningi. Ukusetshenziswa kombhede oshisayo kuyimpoqo. (phakathi kuka-70 no-90 ºC) ukuvimbela ukuthi ingxenye ingaphuki. Uma usebenzisa ishidi le-PEI, qaphela bese ufaka induku encane yeglue ukuvimbela ukuthi ingxenye inganamatheli kakhulu futhi idabule izingcezu zobuso.
Lokhu okubalulekile kuyinkosi ephelele ye izinhlelo zokusebenza zangaphandleImelana kangcono kakhulu nemisebe ye-UV, imvula, kanye nokubanda, futhi inokumelana nokushisa okufika ku-80°C. Ngakho-ke, uma ufuna ukukhiqiza izisekelo zengadi noma izingxenye zangaphakathi zemoto, i-PETG iyisinqumo esifanele.
Esinye isici esibalulekile yiwo Ukunamathela okuhle kakhulu phakathi kwezingqimbaLokhu kuphumela ezingcezu eziqinile kakhulu ezingaqhekeki kalula ngaphansi kwengcindezi. Ngaphezu kwalokho, iyaziswa kakhulu embonini yokudla ngoba ayingeni manzi futhi imicu yayo eminingi iqinisekisiwe ukuthi ixhumene nokudla, ihlanganiswe Ukuphrinta kwe-3D ku-gastronomy.
Umehluko ekuphrinteni nasekucutshungulweni kwangemva kokushicilela
Ngokuphathelene nolwazi lomsebenzisi, i-PLA iyanqoba maqondana nokuhlanzeka. I-PETG, ngokwemvelo yayo, ithambekele kakhulu ekukhiqizeni idumela elibi "ukuhlanganisa" noma imicu emincane ezisele phakathi kwezindonga zengxenye, okudinga ukulungiswa okunembile kakhulu kokuhoxiswa kwe-extruder, into ongayisebenzisa kahle usebenzisa amathuluzi anjenge Bambu Studio.
Ngokuphathelene nezisekelo, i-PLA ithethelela kakhulu. Ngenxa yokuthi i-PETG inokunamathela okunamandla kangaka, Ukususa ama-bracket kungaba yiphupho elibi uma ibanga elanele (okungenani u-0,5 mm) lingashiywanga phakathi kwesakhiwo sokusekela kanye nomodeli wangempela.
Kulabo abajabulela ukupenda izingcezu zabo, i-PLA iyindlela efanelekile ngoba Iyacwebezela futhi ipende kalula kusetshenziswa ama-acrylic. I-PETG, yize ingaphinde ihlanzwe ukuze kufezwe ukuqedwa okucwebezelayo, iyinkimbinkimbi kakhulu ukuyipenda nokuyisebenzisa ngamakhemikhali.
Ngokuphathelene nobuthi, kokubili kuyacatshangelwa izinto eziphephile nezingenabo ubuthiikude kakhulu nentuthu ecasulayo ekhishwa yi-ABS. Noma kunjalo, kuhlale kunconywa ukuphrinta ezindaweni ezinomoya omuhle ukuze ugweme ukuhogela izinhlayiya ezincane zepulasitiki.
Isifinyezo sesicelo: Yikuphi okufanele ukhethe kuye ngephrojekthi?
Uma umgomo wakho uwukudala isithombe sokuhlobisa, isipho esenziwe ngokwezifiso, noma i-prototype lapho isimo kuphela esibalulekile, khetha i-PLA. Yindlela esheshayo futhi ngokuqeda okuhlanzekile kakhulu, ngaphandle kwezinkinga zobuchwepheshe.
Ngakolunye uhlangothi, uma udinga ingxenye ukuze isebenze umsebenzi wangempela, njengesibambi samathuluzi, indawo yokugcina idivayisi kagesi eshisayo, noma yini ezovezwa yizinto ezishisayo, i-PETG ingumngane wakho omkhulu. ikhono lokumelana nokukhathala futhi imiphumela ikwenza kube inketho yobungcweti yezingxenye ezisebenzayo.
Abasebenzisi abaningi abathuthukile bakhetha ukuba nezinqwaba zazo zombili. Basebenzisa i-PLA ukuze qinisekisa i-geometry kanye nomklamo ngokushesha nangokushibhile, futhi uma umklamo usuphelele, baqala ukuphrinta kokugcina ku-PETG ukuqinisekisa ukuthi into ihlala isikhathi eside futhi iqinile empilweni yangempela.
Ukukhetha kokugcina kuncike ekutheni ubeka phambili ubuhle nobulula noma amandla nokuqina. Nakuba i-PLA ilungele umhlaba wobuciko kanye nokuqoqa, i-PETG iyaphumelela emkhakheni wezobuchwepheshe nowezinto ezisebenzayo, okusivumela ukuthi sakhe izinto ezimelana nokusetshenziswa kakhulu ngaphandle kokuwohloka ngokushesha.
