  • Publication number: 20210362225
    Abstract: A multiple axis manufacturing platform for three-dimensional object fabrication in three dimensions and along at least two rotary axes. The platform includes one or more additive and one or more subtractive manufacturing tools. An automatic tool changer (ATS) holds the additive and the subtractive manufacturing tools and selects among them. A movable substrate platform supports a workpiece. A programmable control system has one or more programs for controlling the manufacturing tools, the automatic tool changer and the movable substrate platform, and includes machine code to control one or more relay switches to control the additive manufacturing tools. A machine vision system detects displacement between or features of deposited material. A vision camera mounting for the spindle housing allows viewing the manufacturing process. A laser displacement sensor extracts distance and position of the selected tool or the workpiece.

  • Publication number: 20210229171
    Abstract: An additive manufacturing metal paste and a method of additive manufacturing using the metal paste is presented. The metal paste includes a first metal component of a first majority-phase structural metal, the first majority-phase structural metal comprising approximately 75 wt. % to approximately 90 wt. % first metal particles having a particle size of approximately 1 micron to approximately 100 microns. The metal paste further includes a second metal component of a second bonding metal, the second bonding metal comprising approximately 3 wt. % to approximately 10 wt. %, the second metal particles having a particle size of approximately 3 nanometers to approximately 100 nanometers. The paste further includes a binder having a weight percentage of approximately 2 wt. % to approximately 15 wt. % wherein the metal paste has a sintering temperature of less than approximately 300° C.
