- Umehluko obalulekile phakathi kwe-PETG ejwayelekile, i-PETG engamelana ne-UV, kanye ne-ASA yezinhlelo zokusebenza zangaphandle.
- Ukubaluleka okubalulekile kokomiswa kwe-filament ukuze kuqedwe ukunamathelana kwezintambo kanye nama-bubbles angaphezulu.
- Izinga lokushisa elithuthukisiwe, isivinini, kanye nemingcele yokungenisa umoya ukuze kwandiswe amandla esakhiwo.
- Amasu okunamathela aqinile emibhedeni ye-PEI ukuze kugwenywe umonakalo ohlala njalo ebusweni.
Uma ucabanga ukwenza izivikelo zekhebula noma ezinye izingxenye zobuchwepheshe, i-PETG cishe iyona engcono kakhulu. Kuyinto ethole ukuthandwa okukhulu ngoba ifinyelela ibhalansi ephelele phakathi kokusetshenziswa okulula kwe-PLA kanye nokuqina kwezimboni kwe-ABS, okwenza ibe yindawo efanele kulabo abafuna izingxenye ezisebenzayo, eziguquguqukayo, nezihlala isikhathi eside ngaphandle kokuhlupheka kokusethwa kwemishini okuyinkimbinkimbi. Ukuze ujule kakhulu kulo mehluko, ungabheka umhlahlandlela wethu ophelele wokuqhathanisa i-PETG vs. PLA.
Kodwa-ke, akuwona wonke ama-PETG adalwe ngokulinganayo. Kuye ngokuthi iphrojekthi yakho izogcinwa endlini noma ichayeke elangeni nasemvuleni engadini, kuzodingeka ukhethe uhlobo olufanele lwe-filament. Kule migqa elandelayo, sizokutshela wonke amathiphu abalulekile kanye nokulungiswa kobuchwepheshe ukuqinisekisa ukuthi amaphrinta akho aphuma kahle futhi akudingeki ulahle noma yiziphi izinto.
Inkinga yangaphandle: izinguqulo ezijwayelekile ze-PETG uma kuqhathaniswa ne-UV kanye ne-ASA
Ukuphrinta i-cable sleeve ku-PETG evamile kulula, kodwa uma leyo ngxenye izovezwa ezimweni zezulu, uzohlangana nenkinga: ukubola kwe-photo. Ngokuhamba kwesikhathi, ilanga libangela ukuthi izinto zibe mhlophe, zilahlekelwe umbala, futhi, okubi nakakhulu, zibe lula kakhulu ukuqhekeka nokulahlekelwa ubuqotho besakhiwo sazo.
Ukuze kugwenywe le nhlekelele, kunezinhlayiya ze-PETG ezinokumelana kwe-UV okuqinisekisiwe. Lezi ziqukethe iziqinisi ezimunca imisebe yelanga, zigcine izakhiwo zazo zemishini ziphelele. Ngakho-ke, kufanele ushintshele nini ku-ASA? I-ASA iyinkosi uma kunokushisa okukhulu okuqhubekayo (ngaphezu kuka-62°C), njengasedeshibhodini yemoto. Uma ingxenye yakho ingeke ixhunywe enjinini, i-UV PETG kulula kakhulu ukuyiphrinta ngoba ayidingi igumbi elivaliwe ukuvimbela ukugoba.
- I-PETG ejwayelekile: Ilungele ukusetshenziswa ngaphakathi endlini noma ngaphandle ngezikhathi ezithile.
- Imelana ne-UV ye-PETG: Ukukhetha okuhle kakhulu kwezesekeli zasemanzini, ukuchelela, noma izindawo zokuvala zikagesi zangaphandle.
- NJENGE: Kubalulekile ezindaweni ezinokushisa okukhulu kanye nokumelana okuphezulu kwemishini.
Ukucushwa kobuchwepheshe bokuqeda kobungcweti
Ukuqinisekisa ukuthi ingxenye ayinamaphutha, izinga lokushisa kumele libe liqondile. Ngokuvamile, izinga lokushisa le-nozzle lisukela ku -230°C kuya ku-245°C , yize kuhlale kunconywa ukusebenzisa umbhoshongo wokushisa ngokwemiyalelo yomenzi. Ngokuphathelene nombhede, kufanele ugcinwe phakathi kuka-70°C no-90°C ukuvimbela isisekelo ukuthi singaphumi.
Ijubane liyisici esibalulekile. Ukuze uthole ikhwalithi ephezulu, hlose u-40-60 mm/s. Uma unephrinta yesivinini esiphezulu njengeBambu Lab, ungasebenzisa iBambu Studio ukwenza ngcono imisebenzi esemqoka futhi wandise ijubane, kodwa lungisa amaphrofayili ngokucophelela ukuze ugweme ukunamathela kwengqimba. Imininingwane ebalulekile ijubane lefeni: lisebenzise ku-50-70% ukuze uthole izindawo ezibushelelezi nezibonakalayo , kodwa linciphise uma ubona ukuthi ukuphrinta kuyahlukana noma kuyaphuka.
Isitha esikhulu se-PETG: Umswakama
Uma ubona iphrinta yakho yenza imisindo engavamile, njengemisindo emincane eqhumayo, noma ukuthi ubuso bengxenye yakho ephrintiwe bumahhadlahhadla futhi bugcwele amabhamuza, intambo yakho imanzi. I-PETG i-hygroscopic kakhulu, okusho ukuthi imunca umswakama emoyeni ngokushesha okukhulu. Lokhu kubangela ukugoba okwesabekayo, noma leyo ntambo ecasulayo ebukeka njengolwembu kuyo yonke ingxenye yakho ephrintiwe.
Isixazululo ukomisa i-spool usebenzisa umshini wokomisa we-filament we-3D wasekhaya noma i-oven esezingeni eliphansi lokushisa (phakathi kuka-65°C no-70°C) cishe amahora angu-4 kuya kwangu-6. Qaphela kakhulu ukuthi ungadluli ku-80°C , njengoba i-filament ingathamba futhi ihlangane ngaphakathi kwe-spool, okwenza ingasetshenziswa. Uma seyomile, yigcine njalo ezikhwameni ezivalwe ngejeli ye-silica.
Ukwazi ukunamathela kahle nokugwema izinhlekelele zombhede
I-PETG inezakhiwo ezinamathelayo eziqinile futhi ivame ukunamathela ngokweqile. Uma usebenzisa amashidi e-PEI abushelelezi, qaphela: izinto zinganamathela ngendlela ebhubhisayo futhi ziklebhule izingcezu zobuso uma uzama ukususa ucezu. Ukuze uvimbele lokhu, hlala usebenzisa ungqimba oluncane lwe-lacquer noma induku yeglue ukuze isebenze njengesithiyo.
Uma usebenzisa i-PEI enemibala, ingozi iphansi, futhi ngokuvamile, ukugcina izinga lokushisa lilawulwa kwanele. Icebiso elihle ukuvumela umbhede uphole ngokuphelele ngaphambi kokususa imodeli; ukushaqeka kokushisa kusiza ingxenye ukuthi izikhulule ngaphandle komzamo ongadingekile.
Ukuxazulula izinkinga ezivamile kanye nomklamo ohlakaniphile
Uma uthola ukuthi izendlalelo ziyahlukana, zama ukukhulisa izinga lokushisa le-nozzle cishe ngama-degree angu-5 bese wehlisa isivinini sefeni. Ezingxenyeni ezidinga ukumelana nokucindezeleka, njengezingxenye zekhebula zezimboni, unganciphisi ubukhulu bodonga: sebenzisa okungenani ama-perimeter angu-3 noma angu-4 kanye ne-gyroid infill engu-30%, okusabalalisa ukucindezeleka komshini kangcono.
Ngokuphathelene nomklamo, vimbela amanzi ukuthi angaqongelelani emigqeni yezendlalelo ukuze ugweme ukubola ngaphambi kwesikhathi. Uma uphrinta izimbobo zezikulufo, vumela ukubekezelelana okungu-0.2 mm ukuze zilingane kahle okokuqala ngaphandle kokusikwa amahora amaningi.
Ukuqonda i-PETG kudinga isineke ngesikhathi sokomisa sezinto kanye nokulawula izinga lokushisa okunembile ukuze kugwenywe ukunamathela. Ngokukhetha uhlobo olufanele olusekelwe ekuchayweni yilanga kanye nokuqinisekisa umbhede omuhle wokuphrinta, kungenzeka ukudala izingxenye zobuchwepheshe eziqinile kakhulu ezidlula kakhulu i-PLA kunoma iyiphi indawo edinga amandla.
