FRIDAY NPE 2018 : THE PLASTICS SHOW SHOW DAILY 3D Prinঞng Workshop Has Successful Launch at NPE2018 By Stephanie Hendrixson Addive Manufacturing NPE2018 hosted the 3D Prinঞng Workshop for the first ঞme, on Wednesday, May 9. Approximately 300 plasঞcs profession- als a•ended the half-day program focused on pracঞcal appli- caঞons of 3D prinঞng technologies. Presentaঞons addressed mulঞple uses of addiঞve manufac- turing within the plasঞcs industry, underscoring the fact that 3D prinঞng is now a viable opঞon for far more than just prototyping. Several themes emerged from the workshop presentaঞons: 3D prinng as a means of making mold tooling. Robert Zollo, president and founder of Avante Technology, shared research on 3D prinঞng injecঞon molds with composite mate- rials. Lou Young, president of Linear AMS (Booth S23160), spoke about the use of metal 3D prinঞng to manufacture molds with conformal cooling channels to improve the efficacy of injecঞon molds. Addive manufacturing materials. Zollo's presentaঞon de- tailed the carbon nanotube technology (CNT) materials used in the company's molds and how they differ from other car- bon-reinforced materials. Thomas Fabian, PhD, R&D manager of material science, and Kenneth R. Vessey Jr., staff engineer for performance materials, both of UL LLC (Booths S26079 and WL15), discussed UL's "blue card" approach to approving materials for addiঞve manufacturing, the organizaঞon's answer to "yellow card" material raঞngs for AM. On a related note, a joint presentaঞon delivered by Thomas Raymond, manager addiঞve manufacturing at Arburg (Booth W1325), and Dr. Phillip Brunner, director of strategic accounts, Interfacial Con- sultants, discussed the former's Freeformer 3D prinঞng system that supports the use of standard injecঞon molding resins in pellet form, as well as new, specialized 3D prinঞng materials. 3D prinng for producon. Ken Burns, technical sales direc- tor of Forecast 3D (Booth S23151), and David Tucker, market development manager, 3D prinঞng, of HP, discussed the lat- ter's Mulঞ Jet Fusion 3D prinঞng technology with an emphasis on its usefulness for producঞon parts. Another presentaঞon from Sco• Kraemer, producঞon development engineer at Car- bon (Booth S24160), compared Carbon's Conঞnuous Liquid Interface Producঞon (CLIP) process to convenঞonal injecঞon molding, underscoring that CLIP can produce large quanঞঞes of parts with isotropic mechanical properঞes. Meanwhile, Les- ter Hitch, life cycle soluঞons specialist for EOS North America, highlighted his company's partnership with Under Armour and the potenঞal of 3D prinঞng for shoe manufacturing. Steve Chillscyzn, CEO of Evolve Addiঞve Soluঞons introduced his company's Selecঞve Thermoplasঞc Electrophotographic Pro- cess (STEP) technology, a process that promises speeds com- parable to injecঞon molding for part producঞon. The 3D Prinঞng Workshop is co-hosted by Addive Manu- facturing (Booth S22147), MoldMaking Technology (Booth S33000) and Plascs Technology (Booths S22147, W2513), sister publicaঞons produced by Gardner Business Media. "Stop prototyping. Start producing," urged Sco Kraemer, product development engineer at Carbon during his talk. Presentaঞons at the 3D Prinঞng Workshop emphasized producঞon of end-use parts, along with mold tooling and recent developments in 3D prinঞng materials. 16 GET WITH RAPID Come See Us in Booth #W953 Call +1 724.584.5220 www.rapidgranulator.com You can sell it for pennies a pound, or, you can recover the full value of your regrind and get MORE out of your production.

Steer Highlights Novel Mixer, 'Intelligent Compounding' Plaorm By Jim Callari Plascs Technology The Omega co-rotaঞng twin-screw compounding extruder from Steer America (Booth W5163) is equipped with a Frac- ঞonal Lobe Processor (FLP) to significantly enhance mixing and melঞng capabiliঞes. The firm says the device works on materials in solid state "to achieve inঞmate interacঞon be- tween the consঞtuents while imparঞng physicochemical changes through reacঞon, devolaঞlizaঞon, shear, compres- sion, elongaঞon, surface renewal, distribuঞon, dispersion— alone with minimal interfering effects from other acঞons or in any combinaঞon of acঞons." The FLP reportedly provides the required uniformity in a three-dimensional force field, eliminaঞng hot zones that could result in material degradaঞon. This can be shown by mathe- maঞcal models using analyঞcal methods or computaঞonal fluid dynamic models based on principles of finite elements method. The FLP is also said to eliminate meta-radial shear, thus achieving stable and improved process control in com- pounding materials. Steer demonstrates more than 20 applicaঞons touঞng pro- cess advantages gained by adopঞng "Intelligent Compound- ing." Explains Mike Millsaps, COO, Steer America, "We are employing the Touch & Tell format to elaborate and tell deci- sion-makers the importance of Intelligent Compounding while processing applicaঞons. For every applicaঞon, we present mulঞple processing-challenge scenarios. By clicking on each challenge, users can understand the way forward and the technology needed to improve the processing capability. It is an interacঞve engagement, which elaborates on enhancing the process advantage with Steer technology at the core." The technology demonstraঞon tackles various process challenges, such as dispersion, feeding, pressure control, shear, weমng, dust management, retenঞon, distribuঞon, tem- perature, increased output, residence ঞme.
