CMD - Ceramic Stereolithography

Ceramic stereolithography (CSL), a form of 3D printing and additive manufacturing, is a rapid prototyping and manufacturing process that uses photocurable resin filled with a high loading of ceramic powder to produce ceramic parts using laser stereolithography machines. The parts produced by the stereolithography machine are in the green-state and are subsequently fired to achieve the desired ceramic properties.

Fine Features, Intricate Geometry: The fine laser beam and the automated, layer-by-layer build approach of stereolithography enables ceramic parts with a high level of detail (fine features and complex geometry) that cannot be produced using conventional molding or machining methods.

Ceramic Rapid Prototyping: Ceramic parts are built directly from a three dimensional CAD representation of the parts and do not require any part-specific tooling. This allows rapid, low-cost prototyping of fully-functional ceramic parts without the cost or leadtime associated with tooling.

TA&T Part of Team to Improve EMP Protection

The Defense Threat Reduction Agency (DTRA)/SCC announces the beginning of a Small Business Innovation Research (SBIR) contract with Instant Access Networks, LLC (IAN) and its subcontractors as of March 28, 2016 entitled, “Accelerating Society-wide EMP Protection of Critical Infrastructure and Micro-grids”. DTRA’s request for proposals (RFP) was an invitation to small businesses to participate in a commercial R&D program to create EMP protected micro grids for critical infrastructure needed both on and off military bases and other defense critical infrastructure.  The need was explained by DTRA as follows: “An electromagnetic (EM) attack (nuclear electromagnetic pulse [EMP] or non-nuclear EMP [e.g., high-power microwave, HPM]) has the potential to degrade or shut down portions of the electric power grid important to the DoD….  Restoring the commercial grid from the still functioning regions may not be possible or could take weeks or months.” 

 

A key task on this contract is to demonstrate how to accelerate the adoption of EMP-protected critical infrastructure and microgrids among civilian institutions that need to operate in island mode during a prolonged power outage.   These critical suppliers to military bases include water utilities, hospitals, and emergency communications.  The final report would include proposals for additional research in the improvement of component technologies that comprise an EMP-protected microgrid such as EMP shielding, energy generation, energy storage and energy savings technology.  Those improvements can lead to performance and cost advantages that could make these microgrids competitive with grid provided power in some areas of the country and more easily funded in every location.

 

IAN set its own goal to gather collaborators who will fund EMP protected microgrids for water utilities, hospitals and emergency operations centers so that they don’t have to find funds out of their capital budgets.  Fairfax Water, a subcontractor to IAN in this contract, is a great example because of its critical role to many defense critical infrastructure applications in the national capital region and because of the attractive electricity rates it enjoys.  Fairfax Water supplies Fort Belvoir and the surrounding areas with 163 million gallons of water per day.  Though Fairfax Water  lies outside the base, it is essential for base operations but likely to be vulnerable to  EMP because of its dependence on civilian power grids that are not protected from EMP even though the local utility in this instance is otherwise extremely reliable.  Protecting civilian infrastructure such as Fairfax Water is just as important as protecting the critical applications on the base.

 

IAN developed EMP-protected microgrids that included solar, wind and diesel power generation and control rooms independently tested to exceed military standards for EMP by 1000 fold.  IAN subcontractors include Technology Assessment and Transfer (TA&T), a materials science R&D firm that will provide technical assistance on electromagnetic shielding materials and components of energy storage systems; DC Fusion/ Power Analytics that will provide support for direct current microgrids and modeling software for the design and management of microgrids; Jaxon Engineering and Maintenance who will provide EMP testing support and EMP shielding manufacturing guidance; and Fairfax Water, who will provide water utility management guidance.
