Tungsten is one of the coolest naturally occurring materials in the world. It's a tough, durable metal with the highest melting point of all the elements, and the highest tensile strength at temperatures over 1650°C. Tungsten's naturally occurring isotopes have a half-life so long they're considered stable. Tungsten and its alloys have numerous applications, including incandescent light bulb filaments, X-ray tubes (as both the filament and target), electrodes in TIG welding, superalloys, and radiation shielding. Pure tungsten is even environmentally safe (RoHS compliant).
Smit Röntgen, a Philips brand, started researching the potential of additive manufacturing pure Tungsten products, a decade ago, and by collaborating with specialists in the field, is able to offer pure Tungsten products made by Direct Metal Laser Sintering. This additive process constructs a 3D product by selectively solidifying thin layers of pure Tungsten according to a digital design. The process is mould-less and takes only 48 hours to transform a CAD model into a final product. In addition, it is sustainable, with low power consumption and waste. The product is also 100% recyclable.
Smit Röntgen is now able to accommodate to individual customer needs and wants. "When talking to major players in medical and non-medical fields, it becomes evident that being able to 3D print pure Tungsten parts does attract global attention. By mastering this technique, the possibilities for creating new innovative products and niche markets are endless," explains Pieter Nuijts, Marketing and Sales at Smit Röntgen.
