After three years of work, military researchers are near the end of a project to find a faster, cheaper way to make tools for large aerospace parts like skins for wings and fuselages.

Despite the challenges of COVID-19, research and expert analytics predict market growth in the near future for manufacturing in numerous industries, many of which rely on parts and components that require precision grinding.

Desktop Metal said it received an award from the Department of Defense to develop an additive manufacturing process capable of mass-producing Cobalt-free hardmetals.

Precision grinding operations cover all applications that require dimensions with tight tolerances and low Ra surface finish requirements, including cylindrical external grinding (OD), internal grinding (ID), surface grinding and creepfeed grinding.

While recent advancements in machining centers have allowed for increased capability around high-volume operations, there are several factors that still necessitate the need for grinding.

Christoph Fedler, project director for equipment management at Rolls-Royce Germany, was facing a challenge: He needed to increase the available capacity of the prime discipline at the Oberursel facility, namely micrometer-precise grinding of curvic couplings.

In an announcement orchestrated from Barcelona, California-based HP in June announced an expansion of its 3D printing business.

From Copper to Filaments, engineers are developing new materials for 3D printing, advancing its practical use. In February, Markforged, Watertown, Mass., commercialized a pure copper filament for its printers so they can use this hard-to-machine metal.

3D Systems said the Food and Drug Administration (FDA) has provided 510(k) clearance for maxillofacial surgical guides 3D printed using its LaserForm Ti and DuraForm ProX PA materials.

A burr could become a danger point in the turbine engine. Classical manufacturing processes like turning, milling and grinding can lead to burr formation and unwanted sharp edges.
