Impossible Objects LLC, a Chicago-based company, has brought to market a new composites material manufacturing technology known as Composite-Based Additive Manufacturing (CBAM) 3D technology which produces Carbon Fiber Reinforced Plastic (CFRP) or Polymer Matrix Composite (PMC) parts.
As additive manufacturing emerges from a long infancy, the industry is grappling with a key challenge: A file format and design tools from the 20th century are being asked to do 21st century jobs.
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.
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.
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.
When you walk into the Redeye On Demand facility in Eden Prairie, MN, you enter into one version of the factory of the future. There you will see a bank of 100 high-end Fortus fused-deposition modeling (FDM) machines from Stratasys that provide the capacity to build real, functional parts with production-grade thermoplastics directly from CAD data.
Kevin Smith, senior commercial application engineer at Markforged, explains how the Markforged Metal X 3D printing process works, for starters. He also gets into how FFF metal printing differs from DMLS and other processes. And he goes over materials that can be printed on the Metal X, as well as the applications that are best suited for metal 3D printing.
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.
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.
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.
