Abstract
while choosing 3D printing in preference to traditional manufacturing methods (injection molding, CNC machining or casting), it is worth considering optimizing spatial models for mass reduction. One method of mass reduction is to implement cellular structures into the designed component. CAD software, such as NX, Catia, Creo, SolidWorks are not suitable for this type of operation, due to the fact that they use boundary representations (b-reps) to express the shapes of solid objects. The nTopology software takes a new design approach using implicit modeling techniques. Focusing on the design aspect, the paper proposes workflows to model objects consisting of cellular structures. The emphasis is on the strength test specimens, printing them in both DMLS/SLM and SLS technologies. A volumetric scanning technique was applied to validate the produced objects, thus obtaining a real solid model of the specimens. The aim of the study was to develop configured workflows for the design of the strength test specimens.
