Abstract: Described are high pressure filter housings and apparatuses that are useful to contain a fluid under high pressure, with example housings including first and second pieces having complimentary tapered joint surfaces that can form a fluid-tight seal without a gasket located between the surfaces, and methods of making and using the high pressure filter apparatuses.

Abstract: Described are high pressure filter apparatuses that include first and second pieces having a welded seam along a circumference of the body, and a sleeve placed around and surrounding the welded seam.

Abstract: Described are porous sintered bodies and methods of making porous sintered bodies by additive manufacturing methods.

Abstract: Three-dimensional multi-layer composite structures prepared by additive manufacturing techniques, as well as methods of preparing the structures by additive manufacturing techniques, wherein a multi-layer structure has layers of at least two different thicknesses and a precision thickness are disclosed herein. In some embodiments, a method includes forming a coarse feedstock layer having a coarse feedstock layer thickness, solidifying a portion of the coarse feedstock layer to form a solidified coarse feedstock layer having a solidified coarse feedstock layer thickness, before or after forming the solidified coarse feedstock layer, forming at least one fine feedstock layer having a fine feedstock layer thickness that is less than the coarse feedstock layer thickness, and solidifying a portion of the at least one fine feedstock layer to form the at least one solidified fine feedstock layer having a solidified fine feedstock layer thickness that is less than the solidified coarse feedstock layer thickness.
