The interaction between metal powder and highly accelerated electrons of the beam results in lattice vibration as well as fusion and vaporizing of the raw material.
After a print job is complete, the finished parts need to be removed from the build chamber, separated, and cleaned of excess powder. LED instead of laser or electron beam. Eng. In order to increase the variety of metal alloys applicable for AM, selective laser melting (SLM) of duplex stainless steel 2205 powder and the resulting microstructure, density, mechanical properties, and corrosion resistance were investigated. : Mater. 2,315 Views 105 CrossRef citations to date Altmetric Listen. This is because the part is encapsulated in the material powder and does not need supports to remain stable. Gold* * Correspondence: Scott.Gold@ge.com GE Aviation, Additive Technology Center, 9701 Windisch Rd., St 100, West Chester, OH 45069, USA Abstract Additive manufacturing and specifically metal selective laser melting (SLM) processes are rapidly being industrialized. Selective laser sintering post-processing requires minimal time and labor, and leads to consistent results for batches of many parts. Part Recovery and Post-Processing. Content from this work may be used under the terms … 751 012079 View the article online for updates and enhancements. Special Issue Articles Processing AlSi10Mg by selective laser melting: parameter optimisation and material characterisation. The study looks into the impact of thermal post-processing using Hot Isostatic Pressing (HIPping) and/or T6-peak aging treatment, post-process machining, as well as the build orientation on the microstructural and mechanical properties development in AlSi10Mg … Post-processing with Selective Laser Sintering The key difference between Selective Laser Sintering and other plastic 3D printing technologies is that there is no need for supports. Current post-process heat treatments applied to selective laser melting produced Ti-6Al-4V do not achieve the same microstructure and therefore superior tensile behaviour of thermomechanical processed wrought Ti-6Al-4V. the targeted melting of metal powder using high-power LED light sources — is the name of the new technology that a team led by Franz Haas, head of the Institute of Production Engineering at TU Graz, has developed for
The SEBM-process uses the electron beam as energy source for melting raw material (metal powder). Many components produced with selective laser melting are heat treated to stabilize the microstructure and HIPing is common to heal any internal porosity. Additive manufacturing (AM) is a rapidly growing field of technology. Support structures serve to anchor and stabilize the parts on the substrate plate along with allowing heat dissipation during the SLM process. Post"prpeessingofthese parts at temperature above the glass transition (Tglorthe melting temperature (Tm) ofthe material, sinters the SLSpart

This is because the part is encapsulated in the material powder and does not need supports to remain stable. In order to achieve this goal, obtaining a homogeneous microstructure and eliminating material defects within the fabricated parts are important research issues. These parameters enable … Based on preliminary single-track experiments and building of several sets of trial samples, the parameters presented in Table 2 were selected for processing final specimens.
