Abstract: A technique for additively manufacturing with a segmentation exposure strategy is disclosed herein, which enables lower thermal stress and substrate temperatures, compared to conventional raster strategies. The technique enables manufacture of heat removal devices and other deposited structures, especially on heat sensitive substrates where coefficient of thermal expansion mismatch can be considerable. It also enables novel composites through additive manufacturing. This process can also be selectively applied to parts or material systems that have large thermal stresses with conventional raster and process parameters to reduce chances of thermal stress induced failure. The process enables reduction of heat concentration in selective laser melting or electron beam melting which results in lower residual stresses in the fabricated object.

Abstract: A technique to additively print onto a dissimilar material, especially ceramics and glasses (e.g., semiconductors, graphite, diamond, other metals) is disclosed herein. The technique enables manufacture of heat removal devices and other deposited structures, especially on heat sensitive substrates. It also enables novel composites through additive manufacturing. The process enables rapid bonding, orders-of-magnitude faster than conventional techniques.

Abstract: A cooling device for electronics created ed by additive manufacturing directly on the surface of an electronic device, the colling device created by processes such as controlled focused energy of laser or electron beam, stereolithography, or fused deposition modeling. The cooling device is especially useful in being placed next to or packaged with high-power electronic chips requiring significant heat dissipation.

Abstract: Additively manufactured non-metal particle and metal matrix composites are provided. An intermetallic compound interface layer, e.g., metal carbide, is formed between the non-metal particle, e.g., diamond, and the metal matrix, that enhances thermal transfer. One application of this is to form thermal management structures with high thermal conductivity via laser powder bed fusion. A powder material for additively manufacturing a structure, comprising metal particles; and non-metallic particles with thermal conductivities greater than 100 W/m-K and coefficient of thermal expansion less than 10 ppm/degree C., wherein the metal particles are fusible with heat to form a heterogeneous solid structure around the non-metallic particles with an intermetallic compound interface, the heterogeneous solid structure having enhanced thermal conductivity and lower coefficient of thermal expansion with respect to a homogeneous specimen of the fused metal particles alone.
