Summary: The study evaluated the error rates associated with forensic 3D printed models and toolmarks created using micro-CT data. It found that 3D printed models based on micro-CT scans replicate bone surface geometry with sub-millimeter accuracy, but the printing technology used can affect the accuracy. The authors recommend using micro-CT imaging for producing forensic 3D printed bone models, especially in cases of injuries.

Summary: This article reports a universal manufacturing platform that utilizes photocurable resins and printed salt structures as leachable molds to shape materials into complex geometries. Through systematic investigation of the printing, debinding, and sintering steps, suitable ink formulations for crack-free salt templates are identified. By infiltrating the sintered molds and leaching the templates, complex-shaped architectures are created from various compositions.

Summary: This study aims to assess the environmental impact of using an imine-based covalent organic framework (RT-COF-1) for surface printing (Case A) and 3D inkjet printing (Case B) through life cycle assessment (LCA) methodology. The results show that monomer synthesis is the main contributor to environmental impacts in both cases, and solvents used in Case A also have a significant contribution. Case B has lower environmental impacts compared to Case A. Furthermore, RT-COF-1 compares favorably with polymerizable ionic liquids (PILs) in terms of environmental performance for 3D printing.

Summary: This study demonstrates the use of napkin paper as a substrate for paper analytical devices (PADs) for the first time. The PADs were fabricated using a simple stamping contact method with hydrophobic paraffin barriers. The newly developed PADs showed potential for colorimetric determination of alcohol content in beverages. The results obtained from real samples exhibited good agreement with UV-vis spectrophotometry, indicating the reliability of the PAD-based method.
