There are no fundamental processing differences between laser-based powder bed fusion systems, yet not all machines are created equal. So how do choose and invest in the right equipment? In the first part, we listed what you should be looking for in the hardware equipment. In this second part of a 3-part series, we review different functional and maintenance aspects.
Depending on the mechanism involved in its creation, each type of particles has specific physical characteristics that can impact powder recyclability and contribute defects to the final products. Two key mechanisms are responsible for spatter formation and powder bed denudation in the vicinity of the laser track. Let’s have a look at these.
So it’s best to make sure you have all the unbiased facts at hand to invest your cash sensibly.
In the next 3 articles, we’ll review the points you will want to keep in mind before you invest in AM technology. Hardware, ease of use, maintenance and end-products quality are a few topics you’ll want to discuss in detail with the suppliers. In the first part, let’s have a look at the hardware itself and what you should pay attention to.
Powder recycling is accepted as a key commercial advantage in Selective Laser Melting technology. Yet, surprisingly, little to no information is publicly available on this topic. So what’s the catch?
We provide practical and actionable info dedicated to additive manufacturing of high-value metal components
