“…Because the tire size is large, and the wind tunnel blockage ratio should be less than 15%, the tire model was reduced by a ratio of 1:4 and made by the light curing 3D printer, as shown in Figure 16. The three-dimensional stiffness of 3D printed non-pneumatic tires is basically 50% of that obtained by Wang's simulation [23]. Therefore, the performance of these materials were moderately reduced during the structural design for performance simulation so as to guarantee the prediction of the performance of 3D printed non-pneumatic tires.…”

Application of non-pneumatic tire (NPT) has been increased during the last decade. The aerodynamic characteristics of the wheel with NPT has been studied due to significance on improvement of handling and reduction of fuel consumption. In this paper, first, an original NPT model was simulated by CATIA software, and the influence of NPT structural parameters on aerodynamic characteristics was studied by Fluent software. The simulation calculation results showed that: the reduction of tire width and spoke length, and the increase of spoke thickness can effectively decrease aerodynamic coefficient. Then, the MIRA model was used to study the influence of NPT on aerodynamic characteristics of the whole vehicle under driving conditions. Studies showed that: NPT increased the resistance of the whole vehicle, and 63.1% of the resistance at the wheels was provided by the front wheels. Finally, the wind tunnel test was conducted to study aerodynamic characteristics of the optimized NPT model under static conditions and verify the simulation calculation.

“…TPU is flexible. Hence, the filament is easy to get stuck or flat between the rollers (as shown in Figure 1 a), owing to heat conduction [ 30 , 31 , 32 ]. Herein, the heat transfer from one end to another of the distance (L) of TPU filament can be considered as heat conduction.…”

“…Some previous studies on the effects of geometry (shapes and structures) on the strain sensors [ 28 ] and 3D printing samples [ 29 , 30 , 31 ] are the motivation for the paper. We realize that the geometric approach is easy, fast, and low-cost to improve sensor performance in wearable systems.…”

Health monitoring sensors that are attached to clothing are a new trend of the times, especially stretchable sensors for human motion measurements or biological markers. However, price, durability, and performance always are major problems to be addressed and three-dimensional (3D) printing combined with conductive flexible materials (thermoplastic polyurethane) can be an optimal solution. Herein, we evaluate the effects of 3D printing-line directions (45°, 90°, 180°) on the sensor performances. Using fused filament fabrication (FDM) technology, the sensors are created with different print styles for specific purposes. We also discuss some main issues of the stretch sensors from Carbon Nanotube/Thermoplastic Polyurethane (CNT/TPU) and FDM. Our sensor achieves outstanding stability (10,000 cycles) and reliability, which are verified through repeated measurements. Its capability is demonstrated in a real application when detecting finger motion by a sensor-integrated into gloves. This paper is expected to bring contribution to the development of flexible conductive materials—based on 3D printing.

“…TPE is a flexible rubber-like combination of elastomers and polymers that are also recyclable. It is highly flexible and soft, with particularly good impact resistance and shock absorption (126). Composite materials contain supplements such as metals (e.g., copper and iron) or carbon-based elements (graphene or short carbon fibres).…”

The maker movement has reached the optics labs, empowering researchers to actively create and modify microscope designs and imaging accessories. 3D printing has especially had a disruptive impact on the field, as it entails an accessible new approach in fabrication technologies, namely additive manufacturing, making prototyping in the lab available at low cost. Examples of this trend are taking advantage of the easy availability of 3D printing technology. For example, inexpensive microscopes for education have been designed, such as the FlyPi. Also, the highly complex robotic microscope OpenFlexure represents a clear desire for the democratisation of this technology. 3D printing facilitates new and powerful approaches to science and promotes collaboration between researchers, as 3D designs are easily shared. This holds the unique possibility to extend the open-access concept from knowledge to technology, allowing researchers from everywhere to use and extend model structures. Here we present a review of additive manufacturing applications in microscopy, guiding the user through this new and exciting technology and providing a starting point to anyone willing to employ this versatile and powerful new tool.
