  • Publication number: 20230405936
    Abstract: Commercial additive manufacturing with continuous reinforcement produces parts with low fiber volume fraction and limited printing parameters. Mechanical properties of 3D printed products are improved with high fiber volume fraction. This technology solves, at least, the problem of undetected print fails of currently available technology. Applicator engineering solves the issue of poor interlaminar adhesion. The incorporation of elevated temperature control and real-time monitoring helps solve dimensional errors that happen due to postcuring. This technology mitigates and prevents print failures which will save time and material and improve printing efficiency. Ultrasonic vibration reduces the void in the print by better dispersion of resin.

  • Patent number: 9007058
    Abstract: A method and a dual-stage trapped-flux magnet cryostat apparatus are provided for implementing enhanced measurements at high magnetic fields. The dual-stage trapped-flux magnet cryostat system includes a trapped-flux magnet (TFM). A sample, for example, a single crystal, is adjustably positioned proximate to the surface of the TFM, using a translation stage such that the distance between the sample and the surface is selectively adjusted. A cryostat is provided with a first separate thermal stage provided for cooling the TFM and with a second separate thermal stage provided for cooling sample.
