    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.
