KiSSAM
High-performance, high-fidelity simulation software complex for selective laser or electron beam melting processes at the mesoscale
Mesoscopic simulation of laser powder bed fusion process in KiSSAM.
Why mesoscale?
Mesoscale simulations in KiSSAM predict quality of manufactured material physically based on the melt-pool level, not missing every single detail of the process
Simulated morphology and roughness of a single layer
Overview
Predicted by physics
Computer modeling is a vital aid in the development of new parts, materials, diagnostic tools and machines for additive manufacturing. KiSSAM mesoscale modeling software package is focused on a melt pool level and allows to predict track build quality, inspect melted sample morphology, roughness, porosity, make digital twins of fine thin structures, get absorption and temperature history in a volume up to 1 cm3. KiSSAM takes careful account of all relevant physical effects both for electron beam and laser selective melting additive manufacturing.
Outstanding performance
With a help of well-optimized GPU implemented algorithms on an adaptive mesh, KiSSAM provides fully 3D simulation with small powder particles, pores and meltpool flow resolved with performance of 0.5 – 1 hr of simulation per 1 ms scanning time, which opens a door to massive simulations. With KiSSAM, getting detailed process maps is a task of a few days, not months. KiSSAM module of fast GPU DEM powder filling simulation allows smooth and incredibly fast multilayer simulations. You can get free trial of cloud version of KiSSAM here.
