WEDNESDAY, DECEMBER 13, 2017 / ORLANDO, FLORIDA CAM X 2017 4 SHOWDAILY fiber-reinforced biopolymer developed at ORNL, had 1 / 3 of the embodied energy and an order of magnitude lower carbon footprint compared to the carbon fiber/ resin systems normally used in large scale additive manufacturing. e material is also bio-degradable and designed for high- speed printing with a printing rate of up to 50 lbs/hour. 2017 ACE Award, Manufacturing Category, Material and Process Innovation award was taken by Gifu University (Gifu, Japan) for CFRTP Processing Technology using Commingling, Fiber Laying and "Light" Molding. is new process consists of three independent technologies: High-performance polyamide from Mitsubishi Gas Chemical is spun, then commingled with a carbon fiber yarn without losing textile working ability by Kajirene Inc.'s (Ishikawa, Japan) commin- gling technology. e commingled yarn is laid on a polyamide film by using Tajima fiber-laying embroidery machine. e flat commingled preform is then cured by a microwave irradiation molding system. e process promises to achieve light- weight, low-cost and recyclable composite parts, since tooling needs are minimal and material waste virtually non-existent. 2017 ACE Award, Manufacturing Category, Equipment and Tooling Innovation award was presented to Autodesk (San Rafael, California) for its Comprehensive Composite Manufacturing Platform software. Autodesk's software offering can improve manufacturing efficiency by reducing design and manu- facturing iterations using manufacturability and simulation. is analysis allows users to predict where fiber angle deviation, fiber wrinkle, fiber steering, and compaction issues may occur. 2017 ACE Award, Market Growth Category, Infinite Possibility for Market Growth award goes to Ashland LLC (Covington, Kentucky) for the Ford/ Magna Carbon Fiber Subframe. Magna International Inc. (Aurora, Canada) in cooperation with Ford Motor Co. (Dearborn, Michigan), developed a proto- type carbon fiber composite subframe that not only consolidates the number of parts needed in its assembly by over 80%, but reduces part mass by 34%. e part is compression molded with Ashland's epoxy vinyl ester resin and carbon fiber SMC technology (using Zoltek carbon fiber). AWARDS , continued from page 1 Because the subframe is an integral part of the vehicle's frame, it has greatly expanded the possibilities of composites use in a truly structural application for mass produced vehicles. e subframe, which contributes to rigidity and crash management, has moved into vehicle-level testing at Ford and has the potential to shift the automotive market to consider composites in ways that have not been realized before. Gifu University won the ACE Award Manufacturing Category for Material and Process Innovation for its CFRTP processing, which combines three technologies. High performance polyamide (PA) is spun and comingled with carbon fiber, laid using a Tajima embroidery machine onto a PA film and cured using a microwave molding system. Recycled Carbon Filament Closes the Loop By Ginger Gardiner, Senior Editor CompositesWorld Vartega has developed consumer-grade 3D printer filament for hobbyist and maker applications. Currently available in both acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA), both filaments are made with Vartega's recycled carbon fiber (rCF). ese initial products demonstrate the functionality for stiffer, stronger parts and the potential for Vartega's ongoing development of filaments using engineering thermoplastics such as nylon and PEEK for commercial and professional 3D-printed applications. Vartega's 3D printer filaments offer a closed-loop solution, incorporating carbon fiber recycled from Alchemy Bicycle Company (Denver, Colorado) production scrap, which Alchemy then uses in new part development and prototyping. ese rCF filaments demonstrate improved mechan- ical properties over neat ABS and PLA. ese materials are commercially available from Vartega ( ), including a CAMX 2017 show special: anyone refer- encing coupon code CAMX17-3D will get a 20% discount off of their first spool of 3D printer filament. This 3D printer uses Vartega recycled filament, incorporating carbon fiber from Alchemy Bicycle Co. production scrap.
