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 ...

The team at RP Platform were incredibly interested to read about the launch of Desktop Metal's new metal printing methods, bound metal deposition (BMD) and microwave sintering. The former utilises metal powder bound in plastic filament, then printed using a process similar to fused deposition modelling. The latter utilises existing metal injection moulding materials, which are combined with a binding material and sintered in a specially-designed furnace. It’s always exciting when a new method for 3D printing is unveiled, and these two new approaches certainly have huge implications for additive ...

“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 ...
