    A Framework for Thermal Spray Shape Deposition: The MD* System
    (1991) Weiss, Lee E.; Prinz, Fritz B.; Siewiork, Daniel P.
    This paper present.s t.he framework for a solid-freeform-fabrication syst.em based on thermal spray shape deposition t.o build mult.i-mat.erial st.ruct.ures by incremen tal build-up of t.hin cross-sect.ional layers. The basis of theMD* System (recursively, Mask and Deposit.) is to spray each layer using disposable masks to shape each layer. A thermal spray approach has the potential to build dense parts with desirable mechanical properties. Metal. ceramic, plastic, laminate, and composite structures can be deposited. Since l11asking enables selective deposition wit.hin a layer, complet.e assemblies composed of different mat.erials can be creat.ed in a single process. For example, int.egrated electronic/mechanical structures are feasible.

    Manufacturing Mechatronics Using Thermal Spray Shape Deposition
    (1992) Beck, James E.; Prinz, Fritz B.; Siewiorek, Daniel P.; Weiss, Lee E.
    A new technology for manufacturing mechatronics is described. The technique is based on recursive masking and deposition of thermally sprayed materials. Using these methods, mechanical structures can be created that embed and interconnect electronic components. This results in highly integrated mechatronic devices. A simple, electromechanical artifact was designed and produced to assess the feasibility of these techniques. The details and limitations of this project will be discussed. Areas of future research are identified which are aimed at realizing the full potential of this emerging manufacturing process.
