Purpose This paper presents an investigation into residual stresses in selective laser sintering (SLS) and melting (SLM), aiming at a better understanding of this phenomenon. Design/methodology/approach First, the origin is explored simple theoretical model developed to predict stress distributions. Next, experimental methods are used measure profiles set test samples produced with different process parameters. Findings Residual found be very large SLM parts. In general, profile consists two...
Purpose This paper provides an overview of the different binding mechanisms in selective laser sintering (SLS) and melting (SLM), thus improving understanding these processes. Design/methodology/approach A classification SLS/SLM processes was developed, based on mechanism occurring process, contrast with traditional classifications processed material or application. broad range commercial experimental – found from recent articles as well own experiments used to explain categories. Findings...
Purpose This paper seeks to investigate the possibility of producing medical or dental parts by selective laser melting (SLM). Rapid Manufacturing could be very suitable for these applications due their complex geometry, low volume and strong individualization. Design/methodology/approach The SLM‐process has been optimized fully characterized two biocompatible metal alloys: Ti‐6Al‐4V Co‐Cr‐Mo. Mechanical chemical properties were tested geometrical feasibility, including process accuracy...
Selective Laser Melting (SLM) is an Additive Manufacturing (AM) technique in which a part built up layer- by-layer manner by melting the top surface layer of powder bed with high intensity laser according to sliced 3D CAD data. In this work, mechanical properties like tensile strength, elongation, Young's modulus, impact toughness and hardness are investigated for SLM-produced AlSi10Mg parts, compared conventionally cast parts. It shown that parts comparable or even exceeding those can be...
Selective laser sintering (SLS) is one of the most rapidly growing rapid prototyping techniques (RPT). This mainly due to its suitability process almost any material: polymers, metals, ceramics (including foundry sand) and many types composites. The material should be supplied as powder that may occasionally contain a sacrificial polymer binder has removed (debinded) afterwards. interaction between beam used in SLS dominant phenomena defines feasibility quality process. paper surveys current...
Selective Laser Melting (SLM) is an Additive Manufacturing process in which a part built layer by manner. A laser source selectively scans the powder bed according to CAD data of be produced. The high intensity beam makes it possible completely melt metal particles obtain almost fully dense parts. In this work, influence parameters SLM (e.g. scan speed and thickness) various age hardening treatments on microstructure mechanical properties 18Ni-300 steel investigated. It shown that parts with...
During selective laser melting, the irradiated material experiences large temperature fluctuations in a short time which causes unwanted thermal stresses. In order to assess stresses simple and fast way, new pragmatic method is developed, namely bridge curvature method. The used qualitatively compare influence of different scan patterns, parameter settings more fundamental process changes on residual results from experiments, as well findings literature, lead two general conclusions: that...
Owing to their attractive combination of mechanical properties, high heat conductivity and low weight, the Al–Si alloys found a large number applications in Additive Manufacturing field for automotive, aerospace domestic industries. However, due reflectivity conductivity, they are harder process by Selective Laser Melting. This work elaborates on both optimisation parameters, order get nearly fully dense parts, material properties resulting from this specific combination. A parameter window...
Purpose Selective laser melting (SLM) is a powder metallurgical (PM) additive manufacturing process whereby three‐dimensional part built in layer‐wise manner. During the process, high intensity beam selectively scans bed according to computer‐aided design data of be produced and metal particles are completely molten. The capable producing near full density (∼98‐99 per cent relative density) functional metallic parts with geometrical freedom. However, insufficient surface quality one...
