The growing need for nano and micro components in the medical industries is challenging manufacturers to continually improve upon their manufacturing processes and take a scientific approach to injection molding and tooling.

Machining composites presents unique challenges compared to metals. Reinforcement fibers are abrasive, shortening tool life. The plastic matrix carries away little heat, unlike metal chips, and overheating can melt the matrix.

With all of its accomplishments – including world’s largest defense contractor, and a presence in all 50 states and 70 countries – you might think Lockheed Martin (Bethesda, MD) would already have mastered additive manufacturing.

Digitization of industry has become an established global trend. Despite all the enthusiasm of visionaries, the machine tool is, was and will remain the core element in production.

(Roxbury Twp., NJ) Legionella, the bacteria that causes potentially fatal Legionnaire’s Disease, and other strains of deadly pathogens that are hosted by some cooling towers, have been substantially reduced by the development of a unique anti-microbial HDPE material introduced by Delta Cooling Towers (deltacooling.com) on September 1, 2016.

The partnership is intended to lay the foundation for the two companies to fulfill their shared vision of incorporating additive manufacturing into the traditional manufacturing workflow, helping it to become a universally recognized production practice which can benefit multiple industries, including aerospace, automotive, transportation, energy and industrial tooling.

Researchers at Rice University (Houston) have discovered a titanium-gold (TiAu3) alloy that is harder than most steels and may be an optimal choice for use in orthopedic joint replacement surgery.

Aerospace is one of the main industries embracing additive technologies, and the large growth in industrial metal 3D printing over the past few years can be largely attributed to the A&D industry.

Interesting changes have been happening at Haas Automation, one of the few American machine tool builders left standing after scores have been displaced over the decades by Japanese, German and Korean builders.

Additive manufacturing needs to improve its quality and consistency as it assumes a bigger role in manufacturing, advocates of the technology say.
