Should the US Copyright Office oversee whether 3D printer operators can use feedstock not approved by their machine’s maker to turn out medical devices or airplane parts, or is that the role of the US Food and Drug Administration (FDA) and US Federal Aviation Administration (FAA), respectively?
Additive manufacturing (AM), or 3D printing, is a fast-growing field that offers many advantages over traditional techniques. It can create more complex parts than either machining or casting, can fuse different materials together, and is sometimes less expensive in low-volume or prototype applications.
A fused filament 3D printer has saved a custom outdoor lighting manufacturer tens of thousands of dollars a year, improving operations and winning more business. The purchase also helped retain customers who would previously have gone elsewhere for specialized parts.
Fiber laser welding is all about control of the process, according to Kurt Magedanz, laser process engineer at Ace Precision Machining Corp., Oconomowoc, Wis. With its new Laserdyne 430 systems, Ace Precision has made huge strides with weld quality while reducing operator intervention in the process.
With today’s focus on lightweighting, hollow parts made from composite materials—such as ducting, fuel tanks, mandrels, and rocket shrouds—are in higher demand than ever before.
In my capacity as the Chair of the Council of the Manufacturing USA institute directors, I often get asked about trends in U.S. advanced manufacturing.
AS A TEAM OF FOUR MANUFACTURING engineering undergraduate students from Western Washington University (Bellingham, WA), we had our minds blown within seconds of walking onto the RAPID + TCT show floor when we attended the event, April 23-26, in Fort Worth, TX.
Micro components continue to shrink in size, demanding ever-greater precision and improved handling of parts with sub-micron-sized features. New approaches in micro machining technology include higher-precision systems from traditional micro machining developers, as well as techniques using additive manufacturing processes and semiconductor wafer-scale technology on the smallest of micro parts.
Until the middle of 2010, first-tier subcontract machinist, JJ Churchill, could produce turbine blades only if they had their fir-tree root-forms preground elsewhere, or if they were subsequently added by another subcontractor. No longer is this the case.
Burrs, sharp edges, and rough surfaces plague even the most precise metal-cutting or forming process. Deburring and finishing can often be treated as the step-child of a manufacturing process, but its importance is growing as tolerances get tighter and precision devices become the norm.
