Abstract: A strainer body strainer body has a conical or bullet-like shape and includes a tip portion, a midsection, and a base portion. The midsection connects the tip portion to the base portion such that the tip portion, midsection, and base portion are aligned with one another along a straining axis defined by the strainer body. The strainer body includes a plurality of layers fused to one another and angled relative to the straining axis. The plurality of layers define flow passages that extend through the strainer body to impound particulate entrained in fluid traversing the strainer body through the flow passages of the strainer body.
