Abstract: Embodiments set forth in this application relate to systems and methods by which parts produced by additive manufacturing can be reliably assessed for conformity to a known master model which has quality conforming to the desired specifications. These systems and methods involve recording a thermal history of the manufacturing process of each part. The recorded thermal history is then compared to the previously-recorded thermal history of the master model. Significant deviations in thermal history are indicative of irregularities in the manufacturing build, and the part quality may then be assessed in view of those irregularities.

Abstract: The invention hereof is a new highway deicing additive and a method for deicing asphalt highways. It has been discovered that a small amount of starch added to the salt/water sprayed on highways provides the unexpected property of retaining salt particles in the top portion of the "voids" in the asphalt roads for a period of 2 to 4 hours. The starch can be incorporated into water by mixing; biocides can be added if the starch/water mixture is to be stored more than 2 days. Salt is added to the water/starch mixture prior to deposition on the road. The new treatment works by increasing the viscosity of the aqueous fluid sprayed on the highway to form a water gel structure on the road providing a "platform" for the salt particles in the top portion of the asphalt. The new additive also reduces the need and cost of "follow-up" salt treatments.The additive and method are particularly useful for the new type of asphalt being used on highways in Europe which has a super-porous structure when laid as a road-bed.
