Summary: The increasing popularity of micro-unmanned aerial vehicles (micro-UAVs) among professionals and hobbyists is attributed to the advancement in additive manufacturing technology. Through the use of 3D-printing and topology optimization, ultra-lightweight micro-UAVs can be designed and manufactured without compromising their structural integrity. This article presents the characterization of Nylon 12 (PA12) material properties manufactured using selective laser sintering (SLS) and the application of topology optimization in designing a lightweight micro-quadcopter. The close correlation between numerical and experimental data validates the adoption of topology optimization and 3D printing for the design and rapid prototyping of micro-UAVs.

Summary: An innovative method for creating lab-on-a-chip microflow reactors was developed based on in-depth studies of chemical processes at plastic-metal interfaces. The method involves 3D printing the reactor core with ABS plastic, followed by electroless copper and galvanic nickel plating for a durable and versatile design. Despite the simple procedure and low-cost materials used, the reactors exhibited excellent chemical resistance, modular design capabilities, and high performance in a variety of chemical processes targeting biologically active molecules.

Summary: The effect of canard geometric characteristics on the performance of a lightweight flying wing UAV was investigated using a Design of Experiments approach and the Taguchi method. Based on high-fidelity CFD simulations, optimal design parameter combinations for maximum L/D-cruise and minimum |C-m|(cruise) were determined. Pareto ANOVA analysis revealed that i(c) had the most significant effect on L/D-cruise, while ? was the most important parameter for |C-m|(cruise).

Summary: 3D printing can fabricate engineered lattice structures with tunable surface area and geometries, which have great potential in enhancing structural and functional properties. This study investigates the electrical conductivity of 3D lattices of different sizes, structures, and porosities, providing guidance for the design of additively manufactured electrodes in energy storage devices. The results show that lightweight lattices have higher conductivity compared to random foams, and the specific capacity of supercapacitors can be improved with 3D lattice electrodes. Furthermore, the physical structure of the lattices can be tuned to control the electrical response to mechanical loading, with higher relative density samples exhibiting higher Young's modulus. These findings are valuable for the design of 3D printed electrodes in various electrochemical and electromechanical device applications.

Summary: This study compared two methods for epoxy adhesive bond gap control: one with a geometrical solution and the other using glass beads mixed with epoxy. The results indicated that the glass beads method led to more consistent and better bonding results compared to the geometrical method. Further research on fatigue and interfacial failure modes could be beneficial.

Summary: This paper presents a new method of digitizing large-sized objects by merging the results of long-range laser 3D scanners and structured light handheld 3D scanners. It conducts an overview of the solutions in which these scanners are used and analyzes their measurement accuracy. A reference test object is selected and scanned by two scanners, and significant discrepancies in the results are identified. Therefore, a method of combining the results is developed to collate the advantages of both devices and eliminate their disadvantages.
