A Low-loss and Lightweight Magnetic Material for Electrical Machinery.

A low-loss and lightweight core material, with applications in electrical machinery, is made of highly packed and insulated magnetic microwires (MWs). These MWs are aligned in such a way as to guide the flux in the rotor/stator, with the ultimate goal of increasing efficiency and substantially reducing core losses. Commercial FebalNi29Co17-based MWs with a 127 µm diameter and a 33 µm insulation coating are utilized. The magnetic measurements of the fabricated sample demonstrate high permeability and low core loss in a wide range of frequencies. To prove the utility of this type of material, we used it in the rotor core of a prototype 25 Watt three-phase synchronous reluctance machine (SyncRM). The core is lighter, and the losses are significantly lower than in conventional core materials under the same torque density.

Guidelines for establishing a 3-D printing biofabrication laboratory.

Advanced manufacturing and 3D printing are transformative technologies currently undergoing rapid adoption in healthcare, a traditionally non-manufacturing sector. Recent development in this field, largely enabled by merging different disciplines, has led to important clinical applications from anatomical models to regenerative bioscaffolding and devices. Although much research to-date has focussed on materials, designs, processes, and products, little attention has been given to the design and requirements of facilities for enabling clinically relevant biofabrication solutions. These facilities are critical to overcoming the major hurdles to clinical translation, including solving important issues such as reproducibility, quality control, regulations, and commercialization. To improve process uniformity and ensure consistent development and production, large-scale manufacturing of engineered tissues and organs will require standardized facilities, equipment, qualification processes, automation, and information systems. This review presents current and forward-thinking guidelines to help design biofabrication laboratories engaged in engineering model and tissue constructs for therapeutic and non-therapeutic applications.
