Incazelo emfushane ye- Ukuphrinta kweCarbon fiber 3D

---

I-3D ephrintiwe i-carbon fiber ingubuchwepheshe besibili obufuna kakhulu ukwengeza okwenziwe ngemuva kwensimbi. Ngenxa yezici ezihlukile ze-carbon fiber, njenge: engasindi, amandla aphakeme, ukuqhuba okuphezulu kagesi, ukumelana nokugqwala okuphezulu, izingxenye ezenziwe ngobuchwepheshe bokuphrinta be-3D zivame ukuba nokunemba okuphezulu nokusebenza okuphezulu.

Ubuchwepheshe bokuphrinta beCarbon fiber 3D

Indlela yokuphrinta yeCarbon fiber

▶  I-carbon fiber eqoshiwe igcwalise i-thermoplastic.
  Ama-thermoplastics agcwaliswe ngekhabhoni agcwaliswe nge-fiber fiber aphrintwa kwiphrinta ejwayelekile ye-FFF (FDM) equkethe i-thermoplastic (PLA, ABS noma inayiloni) eqiniswe ngemicu emincane eqoshiwe, okungukuthi i-carbon fibers. Ngakolunye uhlangothi, ukukhiqizwa kwe-carbon fiber okuqhubekayo kuyinqubo yokuphrinta eyingqayizivele ebeka izigaxa eziqhubekayo zekhabhoni ezingxenyeni ezijwayelekile ze-FFF (FDM) thermoplastic substrates.
Amapulasitiki agcwele i-carbon fiber agcwele imicu kanye nemicu eqhubekayo yenziwa kusetshenziswa i-carbon fiber, kepha umehluko phakathi kwawo mkhulu kakhulu. Ukuqonda ukuthi indlela ngayinye isebenza kanjani nokusetshenziswa kwayo okuhle kuzokusiza ukuthi uthathe izinqumo ezinolwazi mayelana nokuthi wenzeni ekukhiqizeni okufakwayo.

Imicu yekhabhoni eqoshiwe empeleni iqinisa izinto ze-thermoplastics ejwayelekile. Ivumela izinkampani ukuthi ziphrinte izinto ngokuvamile ezingenamandla emazingeni aphezulu okuqina. Okokusebenza bese kuhlanganiswa ne-thermoplastic bese kuthi ingxube evelayo ikhishelwe ku-spool ngenqubo yokwenza i-melt filament (FFF).
Okwezinhlanganisela ezisebenzisa indlela ye-FFF, okokusebenza kuyinhlanganisela yemicu eqoshiwe (imvamisa imicu yekhabhoni) nama-thermoplastics ajwayelekile (njengeyiloni, i-ABS noma i-polylactic acid). Yize inqubo ye-FFF ihlala injalo, imicu eqoshiwe yandisa amandla nokuqina kwemodeli futhi ithuthukise ukuzinza kobukhulu, ukuqeda komphezulu nokunemba.
Le ndlela ihlale ingenasici ngaso sonke isikhathi. Eminye imicu eqinisiwe igcizelela ukuqina ngamandla ngokulungisa ukwakheka kwempahla ngentambo. Lokhu kungathinta kabi ikhwalithi isiyonke yomsebenzi, kunciphise ikhwalithi yendawo kanye nokunemba kwengxenye. Ama-prototypes nezingxenye ezisetshenziswa ekugcineni zingenziwa nge-carbon fiber eqoshiwe ngoba inika amandla nokubukeka okudingekayo ekuhlolweni kwangaphakathi noma ezintweni ezibheke kumakhasimende.

Okuqhubekayo izinto ze-carbon fiber eziqinisiwe.
I-carbon fiber eqhubekayo iyinzuzo yangempela. Lesi yisixazululo esonga izindleko sokufaka izingxenye zezinsimbi zendabuko ngezingxenye ezihlanganisiwe ze-3D ngoba kufinyelela amandla afanayo kusetshenziswa ingxenyana yesisindo kuphela. Ingasetshenziselwa ukufaka izinto ezintweni ze-thermoplastics kusetshenziswa ubuchwepheshe obuqhubekayo bokwenza intambo (CFF). Iphrinta esebenzisa le ndlela ibeka imicu yamandla ephezulu eqhubekayo (isb., I-carbon fiber, i-fiberglass noma i-Kevlar) ngombhobho wesibili wokuphrinta ku-FFF ekhishwe nge-thermoplastic ngesikhathi sokuphrinta. Ukuqinisa imicu kwakha "umgogodla" wengxenye ephrintiwe, kuveza umphumela onzima, oqinile futhi ohlala njalo.
I-carbon fiber eqhubekayo ayigcini nje ngokwandisa amandla, kodwa futhi inikeza abasebenzisi ukuqiniswa okukhethiwe ezindaweni lapho kudingeka khona ukuqina okuphezulu. Ngenxa yemvelo yenqubo esemqoka ye-FFF, ungakhetha ukwakha kusisekelo sendlalelo ngalunye.
Kusendlalelo ngasinye, kunezindlela ezimbili zokuqinisa: ukuqinisa okugxile nokuqiniswa kwe-isotropic. I-Concentric igcwalisa iqinisa imingcele engaphandle yesendlalelo ngasinye (ngaphakathi nangaphandle) futhi inwebeke engxenyeni ngenombolo echazwe ngumsebenzisi yemijikelezo. Ukugcwaliswa kwe-isotropic kwakha ukuqiniswa okungahambelani kokunye kusendlalelo ngasinye, futhi i-carbon fiber weave ingalingiswa ngokushintsha indlela yokuqinisa kusendlalelo. Lezi zindlela ezithuthukisiwe zenza ukuba izimboni ze-aerospace, ezezimoto nezokukhiqiza zihlanganise izinto zokwakha ezihlanganayo ekusebenzeni kwazo ngezindlela ezintsha. Izingxenye eziphrintiwe zingasetshenziswa njengamathuluzi futhi zalapho (konke okudinga i-carbon fiber eqhubekayo ukulingisa ngempumelelo izakhiwo zensimbi.), Njengamathuluzi ekugcineni kwengalo, ulwanga oluthambile, ne-CMM zalapho.

Ukusetshenziswa kwezinto zekhabhoni fiber embonini yezingxenye
I-nylon 12CF material, i-3D entsha ephrintiwe ye-carbon fiber material equkethe kuze kufike ku-35% carbon fiber, ngakho-ke inhle kakhulu kuzakhiwo ezifana namandla wokugcina wokuqina we-76 MPa kanye ne-tensile modulus ye-7529 MPa. Ngamandla e-flexha ye-142 MPa, kwanele ukufaka insimbi kokufaka okuningi, kwanele ukufaka izinsimbi ezinhlelweni eziningi, ikwenze kube kuhle kwizimboni zezimoto, i-aerospace nezinye izimboni. Le carbon fiber eqiniswe nge-thermoplastic isetshenziselwa ukukhiqiza ama-prototypes aphezulu wokusebenza angamelana nokuhlolwa okunzima kwezingxenye zokukhiqiza ngesikhathi sokuqinisekiswa kokuklanywa ukuhlangabezana nezidingo ezifunwayo zemvelo yokukhiqiza futhi kungasetshenziswa ekukhiqizeni izinto kulayini wokukhiqiza.
Izinto ze-OXFAB zimelana kakhulu namakhemikhali nokushisa, okubaluleke kakhulu ekusebenzeni okuphezulu kwe-aerospace nezakhi zezimboni. Imininingwane ebanzi yokuhlolwa kwemishini ikhombisa ukuthi i-OXFAB ingasetshenziselwa izingxenye eziphelele, ezilungele ukusetshenziswa zokuphrinta kwe-3D. I-OPM isebenzisa izinkontileka ezisemqoka zentuthuko namakhasimende emkhakheni we-aerospace nezimboni zezingxenye eziphrintiwe ze-3D zezindiza ezentengiselwano nezempi, isikhala nezicelo zezimboni, ezinganciphisa kakhulu isisindo nezindleko.
Namuhla, umkhakha wokukhiqiza okwengezelelweyo uqhume, kanti abanye abaphrinta banikeza amandla okuphrinta ku-carbon fiber. Uma imboni yokunyathelisa ye-3D ifuna ukuthola isabelo semakethe ethe xaxa emakethe yokukhiqiza engama- $ 100 billion, ubuchwepheshe bokuphrinta be-3D budinga ukufakwa kuzo zombili izinqubo zobuchwepheshe nezinto zokwakha. Izinzuzo ezahlukahlukene ze-carbon fiber zibonisa ukuthi kungenzeka ukuthi le njongo ibe ngokoqobo. Ukuze uqiniseke, ukuncintisana nokukhiqizwa kwendabuko, izinto ezihlanganisiwe nakanjani zizoba ngomunye wemandla ashukumisela ukuphrinta kwe-3D ukuba kube ubuchwepheshe obujwayelekile.
