Purpose
Selective laser melting (SLM) is an advanced rapid prototyping or additive manufacturing technology that uses high power density laser to fabricate metal/alloy components with minimal geometric constraints. The SLM process is multi-physics in nature and its study requires development of complex simulation tools. The purpose of this paper is to study – for the first time, to the best of the authors’ knowledge – the electromagnetic wave interactions and thermal processes in SLM based dense powder beds under the full-wave formalism and identify prospective metal powder bed particle distributions that can substantially improve the absorption rate, SLM volumetric deposition …

Patent Enforcement In Cyberterritories, Daniel Harris Brean

3D printing technology has exposed a gap in patent protection. Thanks to 3D printers, physical products can be created and sold digitally in the form of CAD files, and consumers printing the products are effectively manufacturers. But current law would treat a product patent as being directly infringed only when the physical product is made, used, offered for sale, or sold, making it difficult to target the digital source of the infringement. While past scholarship has fashioned new legal constructs to close this gap (e.g., expanding patent eligibility or extending infringement case law) this Article considers whether a proper, analogous …
