Ddm Systems

DDM Systems is an Atlanta-based additive manufacturing and 3D printing startup. The company was founded in 2012 by Suman Das and John Halloran to rapidly commercialize LAMP™and SLE™, two disruptive manufacturing technologies with immediate applications in the aerospace and industrial gas turbines sectors. Large Area Maskless Photopolymerization (LAMP™) is a breakthrough additive technology for the tool-less, on-demand and affordable direct digital manufacturing (DDM) of ceramic cores and integral-cored shell molds for investment casting of high-precision, high-performance turbine engine hot-section components such as airfoils. LAMP produced ceramic cores are fully compatible with current investment casting foundry practices. Scanning Laser Epitaxy (SLE™) builds upon over two decades of metal powder bed-based laser additive manufacturing experience and achieves a breakthrough in manufacture and repair of high-value turbine engine hot-section components made of non-weldable superalloys. SLE achieves controlled epitaxial deposition of equiaxed (EQ), directionally-solidified (DS) and single-crystal (SX) materials to produce fully dense, crack-free structures. This capability surpasses existing metal additive techniques. In response to the rapidly growing demand for both technologies, DDM Systems will deliver commercial systems in 2015.
