The application of new additive technologies is based on models STL models of prototypes that will be build. This paper discusses two additive technologies: Fused Deposition Modeling – FDM and Laser Metal Directed Energy Deposition – Laser DED in terms of program preparation and its verification by simulation of material addition, i.e. machine simulation for these procedures. The paper presents the programming and program verification using machine simulation of additive manufacturing tool path in CAD/CAM and Vericut environment. A procedure for configuring and preparing of a virtual machine for several additive process simulations has been proposed. Simulation is a key technology for program verification. Machine simulation and digital twin are the primary simulation–based approaches in the context of the Industry 4.0. The paper analyzes the available programming software for generating G code from the STL file as well as the possibility of simulating the virtual machine when working according to the generated program.
