Lattice Block Structures (LBS) are used to produce parts with higher specific stiffness than a solid but are difficult to produce. Electron Beam Melting (EBM)technology is capable of building LBS in a variety of configurations directly from a computer file using much thinner and stronger ligaments… More

CalRAM, Inc., a small-veteran owned company, has been developing a capability for producing near-net shape titanium components directly from CAD files. The process uses a layer-build or additive manufacturing process to build 3-D structures by melting titanium powder directly with an electron beam.… More

Lightweight gimbal assemblies capable of meeting both thermal and structural requirements in military aviation environments can be accomplished through the use of titanium alloys. However, to achieve a production unit cost not to exceed $600-$1200 per gimbal assembly for a seeker gimbal assembly… More

ABSTRACT: The designs of complex liquid rocket engine components are limited by the manufacturing processes used to build them. Traditional manufacturing processes, such as, casting or forging and machining, although capable of producing high-quality hardware, are expensive and time consuming. … More

This project will develop the capability to produce naval missile lattice block structures for leading edge components using electron beam melted gamma phase titanium aluminide powder. This is a materials, process, and component development effort. Suitable powder will be purchased and electron beam… More

In 2010, CalRAM was awarded a Phase I SBIR to produce lightweight, low-cost precision seeker gimbals for high volume production that can operate in military aviation environments. Using an additive manufacturing technology based on electron beam melting (EBM), CalRAM built a near-net shape… More
