Reduce part variability and improve tolerance control with a new barrel heating system in which induction coils replace heater bands. Recent tests at Sabic Innovative Plastics in Pittsfield, MA, show that melt streams are exposed to less shear and have a more homogeneous melt temperature when injected into a mold cavity. The induction approach was developed recently by Xaloy, a screw and barrel producer based in New Castle, PA. The report was reviewed at Molding 2008 today in San Francisco.
Several of the new and noteworthy 3D printers in this slideshow are breaking some boundaries in build volume, new metals printing techniques, or working with high-profile development partners to ensure very high-quality parts and controls.
United Launch Alliance will fly 3D-printed flight hardeware parts on its rockets starting next year with the Atlas V. The company's Vulcan next-gen launch vehicle will have more than 100 production parts made with 3D printing. The main driver? Parts consolidation and 57% lower production costs.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
Although bio-based polymers face challenges from petroleum-based polymers, in certain markets they can displace the petro-based incumbents. Here are six new bio-based and renewable plastics for a variety of applications.
BASF has developed tools and initiatives to help engineers use more of its renewable materials in their designs, more effectively, as well as to build parts using them with more predictable performance.
