Summary: Selective laser sintering (SLS) is a complex additive manufacturing technology that uses a layer-by-layer strategy to produce components with complex geometry by melting selected regions of a polymer powder bed using a laser. This review summarizes the physical phenomena involved in the SLS process and the characterization methods for starting materials.

Summary: Inspired by natural helices, this study focused on the fabrication of helical materials with controlled handedness. It was found that helices of opposite handedness exhibited different activity, with the unfavored handedness being self-terminated and the favored handedness showing high activity.

Summary: New energetic polymers based on polytetrazenes have direct incorporation of energetic groups in the polymer backbone, with decomposition temperature at around 130 degrees Celsius and glass transition temperatures ranging from -34.2 to 0.2 degrees Celsius, lowering to -61 degrees Celsius with a new diazidotetrazene plasticizer. Complete room-temperature depolymerization within 1 week is achieved using hexafluoroisopropanol (HFIP), enabling recycling of pyrotechnic compositions with these new binders.

Summary: Selective laser sintering (SLS) with polymers has the potential to revolutionize conventional production processes, but faces challenges regarding reliability and reproducibility. Material marking with SLS is a suitable alternative to ensure traceability and identification of defective components. This study presents a methodology for process optimization through marker-based traceability and evaluates modified polymer marking technology as the most suitable option.

Summary: The study investigates the remote-controllable deformation of grippers made of magnetic polymer composite materials fabricated by SLS printing. Results show that deformation can be regulated by adjusting the magnetic particle content and distance from an external magnet, with the deformation mechanism explored through numerical analysis.

Summary: High-performance elastomers that integrate ultra-high mechanical strength, toughness, and excellent healing and recycling capacities have been successfully fabricated. These elastomers, known as PI-PUU, are composed of rigid polyimide (PI) segments and soft poly(urea-urethane) (PUU) segments dynamically cross-linked with hydrogen bonds. The PI-PUU elastomers possess a record-breaking tensile strength of approximately 142 MPa and an extremely high toughness of approximately 527 MJ m(-3). The elastomer structure consists of a hydrogen-bond-cross-linked elastic matrix and homogeneously dispersed rigid nanostructures. The rigid PI segments self-assemble to generate phase-separated nanostructures that serve as nanofillers, significantly strengthening the elastomers. Moreover, the elastic matrix, composed of soft PUU segments cross-linked with reversible hydrogen bonds, greatly enhances the strength and toughness of the elastomer. The dynamically cross-linked PI-PUU elastomers can be healed and recycled to restore their original mechanical strength. Furthermore, the PI-PUU elastomers exhibit scratch-, puncture-, and water-resistant properties due to the excellent mechanical performance and hydrophobic PI segments.

Summary: Accurately producing geometric features is crucial for advancing additive manufacturing. In this study, the feature resolution for helical channels was quantified and a design rule was proposed to predict success and failure in forming internal helical channels. The ability to clear loose powder was identified as a major factor affecting the production of helical channels.

Summary: Selective Laser Sintering (SLS) technology enables the production of polymeric parts for end-use applications, but the application of carbon-based reinforcements in the electronics industry still faces limitations. This research developed functional composite materials to meet the production requirements for components in direct contact with electrostatic discharge (ESD) sensitive devices.
