We introduce the open-source package MercuryDPM, which we have been developing over last few years. MercuryDPM is a code for discrete particle simulations. It simulates motion of particles by applying forces and torques that stem either from external body forces, (gravity, magnetic fields, etc.) or interactions. The has developed extensively granular applications, in this case these are typically (elastic, plastic, viscous, frictional) contact (adhesive) short-range forces. However, it could...
Laser powder bed fusion (LPBF) is an additive manufacturing (AM) technology. To achieve high product quality, the best spread as a uniform, dense layer. The challenge for LPBF manufacturers to develop spreading process that can produce consistent layer quality many powders used, which show considerable differences in spreadability. Therefore, we investigate influence of material properties, parameters and type tool on quality. discrete particle method used simulate define metrics evaluate...
Abstract Producing a consistent layer quality for different raw-materials is challenge powder-based additive manufacturing. Interparticle cohesion plays key role on the powder spreading process. In this work, we characterise structure of deposited layers in powder-base manufacturing process by numerical simulations using discrete element method. The effect particle evaluated. It found that higher interparticle lead to poor spreadability, with more heterogeneous and enhances size segregation...
