Metal 3D printing was a far-off dream for many manufacturing professionals for a number of years, but now it is not only possible, but easily achievable for most AM operations. This means prototypes and production can be delivered in a range of high-quality metals. One of the most exciting options available nowadays is 3D printed titanium. Today, we’ll be looking at this material’s potential advantages, and the key things you need to know to get the most out of its capabilities.   Why 3D print in titanium? Titanium is already used in a ...

Regular readers of this blog will remember that we recently interviewed Dr Billy Wu of Imperial College London, to talk about some of the cutting-edge 3D printing research taking place there. Particularly notable was the new breed of metal printer that Dr Wu and his colleagues have developed. While additive manufacturing professionals and hobbyists alike have long dreamt of a workable desktop metal printer, but for the most part, such technology remains a long way off. Imperial’s new metal printer not only makes desktop printing with metal materials a viable ...

Germany’s metal powder specialists, H.C. Starck, recently announced the launch of their new range of gas atomized powders, designed specifically with metal 3D printing in mind. Dubbed AMPERPRINTⓇ, the range of powders includes nickel, cobalt and iron-based mixtures, as well as customised powders for specialist applications, such as medical implants. The powders are also available in a range of different powder characteristics, particularly different particle size distributions, which means they can be utilized effectively with a wide range of metal 3D printing techniques. This approach is an intriguing one, as it ...

Any quality 3D printed model -- whether it’s a prototype, a display model or an industrial part -- begins with a quality material. This is especially important for metal 3D printing, as parts intended for industries such as aerospace, defence and automotive must be manufactured to the highest standards. However, the materials used for metal prints are still quite expensive, and so must be deployed intelligently to ensure operations remain cost-effective. A key part of this is maintaining the purity of all powder materials used for 3D printing. Any printing run ...

The post-processing stage for parts generated using direct metal laser sintering is usually quite involved (far more than SLS prints, by way of contrast). However, with a little patience and the right techniques, a world-class result is easily achievable. In today’s tutorial, we’ll look at 5 practical tips to help you achieve the look and mechanical qualities you want for your parts.   1) Make sure your support structures have been removed cleanly Unlike other powder bed technologies, direct metal laser sintering still requires the use of support structures. As these will be ...

Prodways Group recently announced the launch of their Rapid Additive Forging (RAF) technology. This new method of 3D printing metal works by building up layers of molten metal in a cloud of inert gas, allowing parts that would previously have taken several months to produce to be delivered in a few hours, with minimal material waste. The long-term goal of the new technology is to print metal parts in a way that consistently delivers superior metallurgical quality compared to previous methods. At the time of writing, the technology is only ...

“Compared with a traditionally cast part, a printed [part] has superior strength, ductility, and fracture resistance, with a lower variability in materials’ properties.” Elon Musk   While plastic-based materials have been utilised for the majority of additive manufacturing projects since the technology’s inception, recent developments in metal printing materials mean that producing functional metal parts is now not only feasible, but worthy of serious consideration for a range of industries. The possibility of using additive manufacturing techniques to deliver parts with the same mechanical qualities as their machined counterparts has helped open the ...
