Keystone Facilities and Capabilities
Keystone’s Port St. Lucie facility is dedicated to the development of Additive Manufacturing (AM) technologies, housing the robotic AM cell for metal deposition, and 3-D printing of ABS thermoplastic materials for engineering prototypes and models. Keystone’s Florida facility is equipped with computing equipment and analysis tools for extensive probabilistic economic analyses, manufacturing simulation tools, optimization tools, SolidWorks® CAD, and a suite of programming tools. The facility has the ability to deposit metal, form shapes, heat treat parts, and cut up and analyze for microstructural characterization.
Metal Additive Manufacturing: For non-critical parts, reconstructive repair, and tooling made with Additive Manufacturing, Keystone uses an advanced Lincoln Electric pulsed-power metal inert gas (MIG) welding system integrated with a FANUC robot. Since Additive Manufacturing with a robotic platform requires extensive path planning and programming, Keystone used SolidWorks® CAD integrated with RobotWorks® software for CAD-to-Path path planning and off-line programming tools. Keystone has developed laser positioning and IR thermal monitoring controls for the AM processes on the robotic system.
Robotic Additive manufacturing Cell Capable of Open-air, Inert Gas Containment and computer Controlled Deposition
Monitoring Additive manufacturing Work Piece Thermal history using Specialty Infrared Process Sensing and Measurement Capabilities
Heat Treatment, Sample Cutting, Metallographic Analysis: : Keystone has the basic capability to heat treat, cut up, and analyze parts made by the Additive Manufacturing process to assess quality, validate parameters, and support process development activities. These facilities support the ability to make small prototype parts and perform destructive testing. Keystone has local resources for aerospace-quality machining and metallographic analysis to support the internal capability.
