16:9
16:9 (1.77:1) (16:9 = 42:32) is an aspect ratio with a width of 16 units and height of 9. Since 2010 it has become the most common aspect ratio for televisions and computer monitors, and is also the international standard format of HDTV, Full HD, non-HD digital television and analog widescreen television. This has replaced the old 4:3 aspect ratio.

3D Printed and Conventional Membranes
Additive manufacturing, also called 3D printing (3DP), is considered to be a possible approach to produce custom membranes with more manufacturing control than any other method of membrane manufacturing available today. Polymer membranes are central to the proper operation of several processes used in a wide range of applications. The production of these membranes relies on processes such as phase inversion, stretching, track etching, sintering, or electrospinning. Results show that very few membrane materials are used as 3D-printed membranes. Such membranes showed acceptable performance, better structures, and less environmental impact compared with those of conventional membranes.

3D Printed Integrated Sensors
The integration of 3D printed sensors into hosting structures has become a growing area of research due to simplified assembly procedures, reduced system complexity, and lower fabrication cost. Embedding 3D printed sensors into structures or bonding the sensors on surfaces are the two techniques for the integration of sensors.

3D Printing and Biomedical Applications
3D printing is gaining traction in the manufacturing industry, with the benefits of improving productivity and lowering both the cost and number of human-based faults. Given its enormous flexibility and capacity to modify and construct a range of simple to complicated geometries, 3D printing has altered production rates with process automation. 3D printing is swiftly transforming pharmaceutical production to achieve elevated quality therapeutic products with improved process sturdiness in bio-pharmaceutical product evolution, where there is a dependence on medicines manufacturing via conventional manufacturing procedures.

3D Printing of Pure Copper Functional Structures
The 3D printing of pure copper to sufficiently high densities has finally taken off, due to the emergence of commercial-grade printers which are now equipped with 1 kW high-power lasers or short-wavelength lasers.

3DP Medicines and Medical Devices
Novel additive manufacturing (AM) techniques and particularly 3D printing (3DP) have achieved a decade of success in pharmaceutical and biomedical fields. Highly innovative personalized therapeutical solutions may be designed and manufactured through a layer-by-layer approach starting from a digital model realized according to the needs of a specific patient or a patient group. The combination of patient-tailored drug dose, dosage, or diagnostic form (shape and size) and drug release adjustment has the potential to ensure the optimal patient therapy. This document provides an overview on different 3DP techniques to produce personalized medicines and medical devices, highlighting, for each method, the critical printing process parameters, the main starting materials, as well as advantages and limitations.

A New Product Development Model for SMEs
The success of new product development (NPD) is of vital importance for the growth and prosperity of manufacturing companies. Complex product demands are increasing and companies must be able to produce the right products at the right time and at an affordable price; otherwise, they can quickly lose their competitive advantage. Especially vulnerable are small and medium-sized enterprises (SMEs) that can find it difficult to compete with larger companies on a global market and are also more prone to suffer from potential losses related to unsuccessful NPD, as they have a smaller set of both financial and non-financial resources. In order to survive in today’s highly competitive global market, small and medium-sized enterprises (SMEs) have had to transition from sequential to concurrent product development, which significantly shortens development cycles, reduces costs, and ensures high product quality.

AA 6061 Metal Matrix Composites
AA 6061 is an aluminium alloy that has extensive applications due to its superior material characteristics. It is a popular choice of matrix for aluminium matrix composite (AMC) fabrication. Stir casting method is widely for fabricating AA 6061 composites with reinforcements such as SiC, B4C, Al2O3, TiC, other inorganic, organic, hybrid and nanomaterials. An increase in reinforcement content enhances the mechanical and tribological properties of the composites. Hybrid composites show better material properties than single reinforcement composites.

Abrasive Waterjet Machining
Abrasive Waterjet Machining (AWJM) is considered a viable alternative to conventional machining processes, due to its capability of rendering even complex features on parts with high productivity. However, it is currently also important for manufacturing processes to comply with the various aspects of sustainability, by putting emphasis on the environmental dimension apart from the economic. Although AWJM generally is considered an inherently environmentally friendly process, it is required that thorough experimental studies be carried out to evaluate the sustainability of AWJM under various conditions.

Accuracy Improvement in Double-Sided Incremental Forming Process
Low geometric accuracy is one of the main limitations in double-sided incremental forming (DSIF) with a rough surface finish, long forming time, and excessive sheet thinning. The lost contact between the support tool and the sheet is considered the main reason for the geometric error. Toolpath compensations strategies improve geometric precision without adding extra tooling to the setup. It relies on formulas, simulation, and algorithm-based studies to enhance the part accuracy. Toolpath adaptation improves the part accuracy by adding additional equipment such as pneumatically or spring-loaded support tools or changing the conventional toolpath sequence such as accumulative-DSIF (ADSIF) and its variants. It also includes forming multi-region parts with various arrangements. Toolpath adaptation mostly requires experimental trial-and-error experiments to adjust parameters to obtain the desired shape with precision. Material redistribution strategies are effective for high-wall-angle parts.
