With properties superior to conventional titanium, complex geometries can be manufactured quickly and efficiently. However, reactive powder handling, controlled process parameters, trained operators, and part qualification procedures are essential to achieve defect-free results. As expertise develops further, AM using titanium powder provides unprecedented capabilities to manufacture customized, high-performance titanium parts at reduced lead times.<\/p>\n\n\n\n<p><a href=\"https:\/\/en.wikipedia.org\/wiki\/3D_printing_processes\" target=\"_blank\" rel=\"noreferrer noopener\">bi\u1ebft th\u00eam quy tr\u00ecnh in 3D<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Titanium powder is a critical material for printing high-strength, lightweight titanium components using additive manufacturing techniques like selective laser melting (SLM) and electron beam melting (EBM).
