A novel micro-additive manufacturing technique for flexible electronics printing

​​Researchers in the AM3 lab, at the university of Arkansas, have demonstrated the potential for a new low-costs powder bed AM technique for the manufacturing of micro-components made of low-melting temperature (~600C) powders [1]. Unlike Selective Laser Sintering and Selective Laser Melting that employ a laser beam scanned across the powder bed, the new concept, referred to as MAPS for Micro-Array Powder Sintering, employs arrays of micro-heaters as energy sources. This proof-of-concept could increase build speeds and reduce powder waste and running costs.

Powder bed AM machines: ask before you buy

Have a peek under the hood of your powder bed fusion machine and here’s what you get: infra-red laser(s), powder reservoirs and overflows, a spreading mechanism, some form of atmosphere control in the build chamber and a software handling digital files and controlling the process sequence.

Fundamentally, there are no processing differences between suppliers' offers!  

For the price of a house, or a luxury car, you get a machine that will be responsible for the reputational credibility of your company and the commercial viability of your production. Yet, it rarely comes with a builders’ or after sale guarantee. 
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.

Spatter formation in powder-bed selective laser melting

​Strong temperature gradients below the laser generate temperature-dependent and complex hydrodynamic flows in the melt pool that generate spatter formation during build.

​Selective laser melting (SLM) is used to manufacture a patient-specific stainless steel positioning guide for spinal screws. The screws are successfully inserted in the neck vertebrae of a 3-year old patient to strengthen unstable joints. This article highlights the challenges and describes the steps used to design, customise, build and post-process the component.

Orthopaedic regenerative medicine requires the design of scaffolds and implants that replicate the biomechanical properties of bones. Porous implants, designed with bespoke mechanical performance using state-of-the-art of topology optimization and produced by additive manufacturing, are suitable candidates for repairing or replacing damaged bones.
