The market share of sintered metallic materials is constantly increasing and is a permanent stimulus for the development of new materials and new technologies. From the beginning, powder metallurgy was used to produce materials that could not be produced otherwise. However, the obvious advantages of the method have meant that today many applications make use of powder metallurgy, for very different purposes. What makes this technique so attractive is the possibility to control the composition of the starting powders, altering their size, morphology, and internal structure (in micro or nanoscale), which allows some control of the properties of the final products. The forming and sintering process, carried out in several stages or all at once, normally requires the concurrence of pressure and temperature, but more recently it can also include other factors such as electric and magnetic fields, microwave, or laser light. The ultimate goal is usually to obtain fully dense materials with a net shape or near-net shape.
Naturally, these manufacturing and processing routes are becoming increasingly complex. The modeling and simulation of these processes offer virtual tools to assist in the development and optimization of the process, and reduce the cost of experimental testing and material waste.
In this Special Issue, we welcome papers that focus on the forming and sintering methods of metallic powders, with an emphasis on the simulation of such processes. Traditional routes are included, but also the most recent techniques, aimed at producing high-performance products.

This Study investigates the effect of part geometry and infill degrees on mechanical properties of fused filament fabricated stainless steel 316L parts produced with BASF's Ultrafuse 316LX filament. The correlations between infill degrees, mechanical properties, and dimensional accuracy are determined to enhance the part performance via tailored porosity and further establish efficient methods for its product development process. To investigate Young's Modulus, Yield strength, and bending stress, standard testing methods for tensile testing according to DIN EN ISO 6892 and bending testing orientated on EN ISO 3325 will be used. For evaluating the dime-sional accuracy, the tensile and bending specimens are compared to a complex-shaped topology-optimized part. These are measured before and after sintering to analyze anisotropic shrink-age effects and dimensional accuracy linked to the infill structure. A more profound understanding of the process and its capabilities enhances the product development process for metal extrusion-based Additive Manufacturing through these investigations.
