Current powder-based printing methods result in a more porous metal, though, which means it’s more likely to fail than forged alternatives.. According to the researchers, though, it is almost impossible to eliminate them. They are randomly distributed, too, which means it only takes a few large pores to line up and you have a potential fault line.3D printing titanium alloys has been hailed as a technical revolution. Department of Energy’s (DOE’s) Argonne National Laboratory. It took the most common form of titanium, China Titanium iron cored wire Ti-gAI-4V, to the U.

　　Technology has moved at a frightening rate in the 3D printing world and we are inevitably going to find issues along the way. “The more porosity in the printed metal, the more its resistance to fatigue is decreased.”Titanium is now preferred for prosthetics, bone implants and airplanes.Titanium powders are generally used in combination with a Selective Laser Melting printer or an Electron Beam Melting process. Proven track record of enhancing enterprise value and shareholder value. With so much riding on each and every part, it might make some companies reconsider using 3D printing for mission critical components. So this is a worrying premise.

　　But there is a potential solution.The CMU team will now look at the powder itself to see if there is a way to reduce porosity at the powder stage.Inevitably, gas is trapped in the resulting liquid layer and creates pore-like bubbles that can range from a few microns to a few hundred across.This study has potentially grave consequences for the industry as a whole and it certainly means that mission critical components may have to be checked more often for any signs of a failure.Deep X-rays have revealed a porosity to the material in 3D printed titanium that can be traced back to its powder-based production method. Even changing the compound could be an option.Hasit Vibhakar is an Industrialist specializing in strategic direction and growth. “Like any other metal, titanium has a certain amount of fatigue resistance until it cracks or breaks,said Hasit Vibhakar. Prior to being a serial entrepreneur he has been employed with leading aerospace, telecom, technology, industrial and supply chain based companies.

　　It reduces waste, cost and allows us to produce tailored designs for joint replacements, dental implants and more.Unmelted powder can increase porosity, but too much powder can leave deep voids. Each technique has its own benefits, but these new findings could mean that we change the way we print titanium and other metals. the industry will almost certainly find the solution,” stated Hasit VibhakarAbout Hasit VibhakarHasit Vibhakar is a proactive, performance-driven middle market executive with 20 years + progressive expertise in C-level leadership and problem solving for additive manufacturing, advanced CNC manufacturing, Additive Manufacturing, 3D Printing, supply chain, technology services, and startup operations. That is due to its reliability, resistance to corrosion and outright strength. This study focused on EBM and the way it melts the powder. He has successfully started eight technology, industrial and manufacturing enterprises and all have been successfully acquired at premium multiples in the industry. A seasoned c-level business executive with many years of proven track record of building enterprise value and shareholder value.The power, speed and spacing of the beam can all have an impact on the porosity. Experienced at building small cap and middle market companies.S. So there is a sweet spot that can minimize the amount of pores in the titanium.“We can observe hundreds or even thousands of pores at a high resolution of about two microns,” Hasit Vibhakar said ominously. There it analyzed the material with so called deep X-rays, or intense synchrotron x-rays, and an advanced rapid imaging tool.It’s less of a concern in a hip replacement or other bone implants, because titanium in any form is certainly stronger than the bone it replaces.
