The Defense Advanced Research Projects Agency (DARPA) is soliciting innovative approaches to demonstrate an additive manufacturing (AM) technology with new materials to enable fabrication of complex microsystem geometries. The principal objective of the AMME program is to invent radically new approaches to additively manufacture three-dimensional (3D) non-planar microsystems.
Description Most additive manufacturing technologies use thermoplastic material systems, which are easy to process and suitable for large-scale manufacturing. But cooling and solidifying of previously deposited layers causes residual stress to build. This build-up arises because of the contraction of deposited beads during cooling, stressing the previous layers, which have already mostly contracted.

With AM-PM, calculations are performed faster than similar methods and the technique can be generalized to other additive manufacturing processes.
The advantages of additive manufacturing are reduction in material costs due to near net shape part builds, minimal machining required, computer assisted builds for rapid prototyping, and mass production capability. Traditional thermal nondestructive evaluation (NDE) techniques typically use a stationary heat source such as flash or quartz lamp heating to induce a temperature rise.
The Contractor shall provide advanced airworthy additive manufacturing (AM) capability and capacity to the USAF at WR-ALC/CMXG, Robins AFB, GA including delivery, installation, and certification of one GE Concept Laser mode M2 Series 5 additive manufacturing system and associated peripheral and post-processing equipment.The only approved source for these items is General Electric (GE) Company.This solicitation will result in a Firm Fixed Priced Delivery
This document describes a metal Additive Manufacturing (AM) system for the Metal Workingand Machining Shop Set (MWMSS). The MWMSS is an assemblage of machinists cutting,measuring, and welding equipment integrated into two one side expandable 8’x8’x20’ mobileshelters. The MWMSS was designed to support the Military Occupational Specialty (MOS) 91Ethat combined the previous 44E (Machinist) and 44B (Metalworker/Welder).
