- I-PLA ivelele ngokusebenziseka kwayo okulula kanye nokuqeda kwayo ubuhle, okwenza kube ukukhetha okuhle kwabaqalayo kanye nezingcezu zokuhlobisa.
- I-PETG inikeza ukumelana okuphezulu komshini nokushisa, okwenza kube yinto ekhethwayo yezingxenye ezisebenzayo nezangaphandle.
- Zombili izinto ziphephile futhi azinabo ubuthi, yize i-PETG idinga izinga lokushisa eliphakeme kanye nombhede ofudumele ophoqelekile.
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 ukuthi amaphrojekthi akho adinga okungaphezu nje kwengxenye enhle egoba ngokushisa.
Ukukhetha phakathi kwe-PETG ne-PLA akukhona ukuthi yikuphi okungcono kakhulu, kodwa kunalokho ukuthi yini ofuna ukuyenza . Ngenkathi enye iyinkosi yobuhle nobulula, enye iwumsebenzi walezo zingxenye okumele zibhekane nokuguga 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 ibe yinto ebolayo futhi enobungani nemvelo . Kunoma ubani oqalayo, kuyisinqumo esinengqondo ngoba kulula kakhulu ukuyiqonda futhi ayidingi ukusethwa komshini okuyinkimbinkimbi.
Enye yezinzuzo zayo ezinkulu ukuthi ayidingi umbhede ofudumele ukuze isebenze, yize ukuyisebenzisa kungasiza. Ngaphezu kwalokho, iqiniso lokuthi ayikhiphi iphunga elinamandla (ngezinye izikhathi iphunga elimnandi kancane) lenza ifaneleke kakhulu ekuphrinteni emakamelweni angenawo umoya wokungenisa umoya ezimbonini, uma nje ifasitela ligcinwa livulekile ukuze kujikelezwe umoya.
Ngokuphathelene nekhwalithi yokubonakala, i-PLA ayinqobeki. Inikeza imiphetho ebukhali kakhulu kanye nokunemba okuhle kakhulu kobukhulu, okwenza ifaneleke 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: ukumelana kwayo nokushisa okuphansi . Uma ushiya ingxenye ye-PLA kudeshibhodi yemoto yakho maphakathi no-Agasti, cishe izogoba, njengoba iqala ukuthamba cishe ku-60°C. Futhi akuyona 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. Ihlanganisa okuhle kakhulu kuzo zombili lezi zindawo , inikeza umthelela omkhulu kakhulu kanye namandla okuguquguquka kune-PLA.
Ngokungafani nomzala wayo olula, i-PETG idinga amazinga okushisa aphezulu okukhipha, ngokuvamile aphakathi kuka-230 no-260°C, futhi umbhede ofudumele (phakathi kuka-70 no-90°C) uyadingeka ukuvimbela ingxenye ukuthi ingaqhekeki. Uma usebenzisa ishidi le-PEI, qaphela bese ufaka inani elincane lenduku yeglue ukuvimbela ingxenye ukuthi inamathele kakhulu futhi idabule izingcezu zobuso.
Le nto iyindlela engaphikiswana ngayo yokusetshenziswa kwangaphandle . Imelana kangcono 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 ukunamathela kwayo okuhle kakhulu kwezingqimba , okuholela ezingxenyeni eziqinile kakhulu ezingaqhekeki kalula ngaphansi kwengcindezi. Ngaphezu kwalokho, iyaziswa kakhulu embonini yokudla ngoba ayingeni manzi futhi imicu yayo eminingi iqinisekisiwe ukuthi ixhumene nokudla, okwenza kube ithuluzi eliwusizo lokunyathelisa nge-3D emkhakheni wokupheka.
Umehluko ekuphrinteni nasekucutshungulweni kwangemva kokushicilela
Ngokuphathelene nolwazi lomsebenzisi, i-PLA iyanqoba uma kukhulunywa ngokuhlanzeka. I-PETG, ngokwemvelo yayo, ithambekele kakhulu ekukhiqizeni "izintambo" noma imicu emincane edumile ehlala phakathi kwezindonga zengxenye, edinga ukulungiswa okunembile kakhulu kokuhoxa kwe-extruder, into ongayisebenzisa kangcono usebenzisa amathuluzi afana ne -Bambu Studio.
Ngokuphathelene nezisekelo, i-PLA ithethelela kakhulu. Ngenxa yokuthi i-PETG inokunamathela okunamandla kangaka, ukususa izisekelo kungaba yiphupho elibi uma ungashiyi isikhala esanele (okungenani u-0,5 mm) phakathi kwesakhiwo sokusekela kanye nemodeli yangempela.
Kulabo abajabulela ukupenda izingcezu zabo, i-PLA iyindlela efanelekile njengoba icwebezela futhi ipeyinta kalula isebenzisa ama-acrylics. I-PETG, yize ingacwebezelwa ukuze kufezwe ukucwebezela, iyinkimbinkimbi kakhulu ukuyipenda nokuyisebenzisa ngamakhemikhali.
Ngokuphathelene nobuthi, kokubili kubhekwa njengezinto eziphephile nezingezona ezinobuthi , ezikude kakhulu nentuthu ecasulayo ekhishwa yi-ABS. Noma kunjalo, kuhlale kunconywa ukuphrinta ezindaweni ezinomoya omuhle ukuze kugwenywe 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 eshesha kakhulu enokuphela okuhlanzekile , ngaphandle kwezinkinga zobuchwepheshe.
Ngakolunye uhlangothi, uma udinga ingxenye ukuthi ifeze injongo ewusizo, njengesibambi samathuluzi, indawo yokugcina idivayisi kagesi ekhiqiza ukushisa, noma yini ezovezwa yizinto ezishisayo, i-PETG iyindlela engcono kakhulu ongayisebenzisa. Ukumelana kwayo nokukhathala kanye nokuthinteka kwenza kube ukukhetha kochwepheshe kwezingxenye ezisebenzayo.
Abasebenzisi abaningi abathuthukile bakhetha ukuba nezimbobo zazo zombili. Basebenzisa i-PLA ukuqinisekisa ngokushesha nangokungabizi i-geometry kanye nomklamo , futhi uma umklamo usuphelele, benza ukuphrinta kokugcina ku-PETG ukuqinisekisa ukuthi into ihlala isikhathi eside futhi iqinile ekusetshenzisweni kwangempela.
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.
