The ever-volatile oil and natural gas industry—roiled most recently by September’s drone attacks on Saudi Arabian oil facilities that temporarily reduced the kingdom’s output by nearly half (about 5 percent of global production)—faces particularly challenging requirements for machined components to meet evolving supply targets.
Fort Collins, Colo.-based Wohlers Associates announced the publication of “Wohlers Report 2019,” the 24th annual installment of its undisputed, industry-leading report on additive manufacturing (AM) and 3D printing. The worldwide study reports on growth, development, and the future of AM materials, applications, systems, services, design, software, patents, startups, standards, investment, and research.
Two new production resins are available for 3D printing: one from 3D Systems is a thermoset that thinks it’s a thermoplastic and another from Carbon is a hybrid that’s 30 percent biomaterial, the company’s first resin with a reduced carbon footprint.
Additive manufacturing (AM) once was called “rapid prototyping.” Its earliest forms made prototype parts—and nothing else. However, manufacturers were intrigued by the prospect of using it to make cost-effective metal parts in production. That day is here.
Necessity, as the saying goes, is the mother of invention, and this symbiotic relationship between need and solution was on full display at a recent two-day, two-location event hosted by GF Machining Solutions.
Laser welding is a superior technology for repairing defects in tooling, plastic injection molds, stamping dies, blow molds, turbine blades, and nearly any tooling component made of stainless steel, aluminum, copper alloy, cast iron, and all tool steels.
Metalworking is a great industry that makes a major contribution to the U.S. economy, but it doesn’t typically attract movie idols or sports stars. That changed when NASCAR champion Brad Keselowski joined the ranks of metalworking entrepreneurs.
While looking for inspiration for this column,Ilene Wolff came across a rousing magazine headline. “Why the Women in 3D Printing Innovator Award Is Important,” the TCT Magazine headline read.
Rapid prototyping is a staple of every designer and engineer’s workflow—essential for testing new concepts, verifying designs, and meeting increasingly aggressive time-to-market goals. Regardless of the industry or product, all engineers must consider the speed, accessibility, cost, and output of these additive manufacturing equipment.
