Lockheed Martin, Inkampani yaseMelika egxile kakhulu ezindabeni zokuphepha kwe-Aerospace, ikakhulukazi ezinikele ocwaningweni, ekuthuthukisweni nasekukhiqizeni izinhlelo namasevisi athuthukile, isanda kumangaza umhlaba wokuphrinta kwe-3D ngokwethulwa kwelungelo lobunikazi elingajwayelekile ngoba bakhombisa izinqubo ezidingekayo ukudala iphrinta ekwazi uku dala amadayimane okwenziwa cishe kunoma yisiphi isimo.
Lo mshini omusha ngabe waklanywa umsunguli UDavid G. Findley futhi kungaba kuhle ekwakheni amathuluzi aqinile kakhulu njengamasaha, imimese, izivivinyo kanye nezikhali ezilula. Ngokuyinhloko, njengoba kumenyezelwe yinkampani yaseLokheed Martin, izosebenza kuze kube qhubeka nokuthuthukisa izindiza zokulwa eziphambili kakhulu zenkampani noma kunjalo, amathuba ayo ayamangalisa impela ngoba kungenzeka abekhona ezimakethe eziningi.
U-Lockheed Martin ukhombisa ukwakheka kwephrinta yedayimane ye-3D
Ukungena emininingwaneni ethe xaxa, sibhekene nephrinta ye-3D ezosebenzisa i-pre-ceramic filler nanoparticle polymer. Kulokhu kufanele sengeze ukuthi umshini kufanele usebenzise izinto ezimbili eziyinhloko ze- i-ceramic powder ne-pre-ceramic polymer. Amakhanda wephrinta afaka lolu ungqimba lwezinto ngongqimba kuze kube yilapho kwakhiwa into oyifunayo, okumele kamuva ibhakwe emazingeni okushisa aphezulu. Ekugcineni, futhi njengenjwayelo, uthuli olweqile lwesibalo kufanele lususwe.
Umehluko phakathi kwelungelo lobunikazi le-Lockheed Martin nezinye izindlela zokuphrinta ze-ceramic ukuthi ucacisa ukuthi kungenzeka yini ukuphrinta izinto ezakha amadayimane okwenziwa ngenxa ye-polymeri yayo yangaphambi kobumba indlela ye-pyrolysis okuyiyona esetshenziselwe ukwakhiwa kwayo.
Njengoba kumenyezelwe yilabo ababhekele le phrojekthi, enye yezinzuzo zephrinta entsha ngaphezu kokukhulisa amathuluzi amelana ne-ultra kungenzeka ukuxuba izinto ezifana nezinhlobo eziningi zama-polymeri angaphambi kobumba kanye ne-powders ye-ceramic ehlanganisiwe inikela ngezinzuzo ezihlukile zobuchwepheshe, ngamabumba ukuthi ingamelana kuze kufike ku-1.400 ºC.
