High power Xenon flash can produce intense irradiation of the metal powders causing their rapid heating, sintering, and even melting. Present experiments employed commercial Xenon lamp capable of producing irradiation pulses with energy up to 60 – 80 J/cm2 per pulse with pulses lasting up to few tens of milliseconds. Custom mirror surrounding the lamp provided uniform irradiation over powder’s area of about 140 cm2. Powder sintering and melting under a single pulse irradiation was demonstrated for a variety of commercial metal powders, including Al, brass, Cu, Ni, Hastelloy, stainless steel, Ti, and Cr. Tuning of the pulse shape and energy, and application of multiple pulses allowed to overcome difficulties related to a very high surface energy of molten metal particles and provided layers with density exceeding 98% of the solid metal. Advantages and challenges of this 3D printing process will be discussed.
