Summary: This work proposes a simple methodology based on the Discrete Element Method (DEM) and lumped heat transfer equations to simulate selective laser sintering processes in advanced manufacturing. It takes into account various thermal phenomena and phase transformation for thermo-mechanically-active particles forming discrete particle systems. Numerical examples are provided to demonstrate its practical use.

Summary: Selective laser sintering (SLS) is an additive manufacturing process with potential in producing medical devices, such as hip cups and dental crowns. SLS-based 3D-printed dosage forms can revolutionize the production of personalized drugs due to the ability to manipulate material porosity and create amorphous solid dispersions in a single step.

Summary: Alumina/molybdenum nanocomposites were successfully synthesized and sintered using a CO2 laser. The distribution of metallic molybdenum particles at triple points and grain boundaries in the alumina matrix plays a crucial role in promoting densification and affecting the microstructural evolution of the composite during sintering.

Summary: Selective laser flash sintering (SLFS) is a flash sintering variation that utilizes a scanning laser as the only external heat source. This study focuses on understanding the charge transport mechanisms during stage I SLFS in yttria stabilized zirconia. Experimental results show that both a discrete bundle of charges and continuous flow of charge carriers contribute to the current at the initiation of SLFS.

Summary: Flash sintering is a rapid densification method for ceramics that combines heating and electric fields, and can be initiated using a scanning laser. In addition to YSZ, AlN is shown to undergo selective laser flash sintering, with initiation governed by local input energy density and heat dissipation.

Summary: The study found that lightweight polymeric lattices fabricated by SLS exhibit good energy absorption performance under quasi-static compression, but are prone to catastrophic collapse when subjected to impact. The use of different manufacturing techniques, such as FDM, can result in lattices with better energy absorption characteristics. The novel HS lattice design shows superior energy absorption characteristics for all tests compared to traditional octet and RD structures.

Summary: By combining a direct selective laser sintering process with a laser preheating procedure, the temperature gradient and thermal stress were reduced, leading to the successful additive manufacturing of BaTiO3 ceramics. The resulting h-BaTiO3 layer showed high relative density, absence of pores or microcracks, and a Vickers hardness 70% higher than conventionally sintered t-BaTiO3 ceramics.

Summary: In the study, lignin was introduced as a suitable component for selective laser sintering (SLS) of polyamide (PA12) to reduce costs while maintaining or improving processability and performance. The addition of lignin in SLS resulted in composite material with improved thermal stability and mechanical properties, while also influencing the surface properties and wettability of the structures. The research demonstrated the potential of lignin valorization in composites through SLS, allowing for reduced cost, scalability, and easy processing.

Summary: This paper reports an ultra-fast sintering phenomenon of alumina achieved through scanning laser irradiation. The study found that alumina can be sintered to high density in a short time using laser scanning, with a different microstructure compared to furnace-sintered alumina. The grain size and relative density of laser-sintered alumina vary from the center to the edge of the laser beam, and the sintering mechanism is affected by the laser scanning speed.

Summary: The susceptibility to hydrogen pores in the welded joints of SLM AlSi10Mg alloys was investigated through different welding methods. It was found that autogenous laser welding and single-pass laser welding had a high sensitivity to hydrogen pores, while LMD welding effectively reduced the size and porosity of the pores. SLM AlSi10Mg alloys exhibited lower hardness and ultimate tensile strength in laser welding compared to LMD welding, which can be attributed to the refined microstructures and reduced hydrogen pores in the welded metal.

Summary: 3D printing technology, particularly selective laser sintering (SLS), offers great potential in pharmaceutical manufacturing for personalized medicine. The modulation of printed material porosity is a key feature of SLS for pharmaceutical applications. Despite challenges in drug stability and powder recycling, collaboration between pharmaceutical industries and compounding pharmacies could help overcome these hurdles and further the deployment of SLS in clinical practice.

Summary: Three-dimensional printing technologies can fabricate complex parts with accurate geometry and less production time, and can be applied to biomedical applications through direct or indirect bioprinting approaches. Scaffolds are commonly used for cell culture, but direct bioprinting may offer a more efficient way to mimic cell interactions.
