Summary: The paper discusses the CNC component manufacturing process using the WAAM process. It describes all the execution steps from CAD drawing to examination and economic calculation. The WAAM process proves to be more advantageous, especially when a single piece is needed and expensive titanium alloys are used. The cost of obtaining a component using the WAAM process is significantly lower compared to using another manufacturing process, as shown in this paper. In conclusion, additive manufacturing can be a feasible solution for industrial applications when replacing a classic manufacturing process.

Summary: The pharmaceutical industry is transitioning from traditional batch processes to continuous manufacturing. Wet granulation, however, has been challenging to incorporate into continuous processing due to limited equipment options for continuous granule drying. A new equipment combining a twin-screw wet granulator and a novel horizontal vibratory fluid-bed dryer has been developed and shown to effectively granulate and dry a range of formulations, producing granules of similar or improved quality compared to batch wet granulation and drying.

Summary: This paper considers a topology optimization formulation that includes a model of the layer-by-layer additive manufacturing process. By formulating it as a multi-objective minimization problem, the performance and cost of both final and partially manufactured designs are taken into account, along with addressing important AM-related issues such as overhang and residual stresses. The study shows that the proposed approach is computationally viable and can avoid issues associated with geometry-based formulations for overhang limitation.

Summary: This study optimized the additive manufacturing process through research on CMT arc modes and interlayer cooling time, finding that the CMT mode was the most stable process, while the CMT+P mode had finer grains and higher hardness. The study also revealed the mechanism of tensile anisotropy and the weak points of columnar grains at grain boundaries, showing that horizontal tensile strength is smaller than vertical tensile strength due to more grain boundaries.

Summary: Selective laser sintering (SLS) is a highly precise 3D printing process used in various fields such as medical, aerospace, and art industries. The thermal phenomena generated by SLS are crucial for analyzing microstructure, mechanical properties, residual stress, and deformation of produced parts. By using a three-dimensional element finite method, researchers can investigate temperature evolution in SLS and study the effects of different parameters on the quality of polyamide parts manufactured by this process.

Summary: The influence of extrusion infill angles on the mechanical properties of 3D printed test specimens were investigated in this study. Different polylactide (PLA) specimens with varying infill angles were manufactured and tested using Computed Tomography (CT) scanning and optical measuring system. The results showed significant deviation between the real geometry behavior and the model. Finite Element Method (FEM) simulations were also conducted, which predicted an increase in stiffness, ultimate tensile strength, and strain at failure due to geometric deviation. The goal of this work is to evaluate the stiffness and strength of FFF-printed components using FEM with a justifiable testing effort, considering the directional dependence and suitable strength criterion.

Summary: This study aims to establish a multi-step optimization methodology for FFF technology, using PLA as a case study, in order to make FFF more applicable across different material types. The results showed that different materials require different optimal print conditions, where part dimensions and tensile properties varied depending on the combination of various parameters. By implementing the filament-specific optimization framework established in this study, more efficient processing of new materials will be possible for enhanced applicability of FFF in the 3DP field.

Summary: This paper presents a new topology optimization approach that considers the fabrication characteristics and constraints of extrusion-based additive manufacturing (AM). Through mimicking the fabrication process and introducing a fixed radius feature size, the design results promote the continuity of design features and account for weak bead bonds. The algorithm is demonstrated on benchmark problems and the design results respond to user specifications on bead size and relative bond weakening.

Summary: Recent advances in robotics have allowed humanoid robots to physically interact with humans, particularly in robot-supported caregiving. This physical human-robot interaction (pHRI) necessitates physical contact, which can be enhanced through efficient sensing methods. In this study, we utilized a flexible tactile sensing array as a tactile skin for the humanoid robot HRP-4C. Our novel spatial calibration approach using B-spline surfaces accurately determines the locations and normals of the sensor cells when attached to the robot. We demonstrate the successful integration and use of our flexible tactile sensor for robot control tasks, marking a significant step in incorporating flexible tactile sensors in pHRI applications.
