An additively-manufactured heat exchanger includes fluidly-separated alternating first and second layers having respective flow channels which can include one or more features that is either a riblet or a turbulator. A riblet includes a riblet peak and/or a riblet valley, which has a riblet slope, and the riblet peak and/or riblet valley has a riblet axis that is generally parallel to either the first fluid flow direction or the second fluid flow direction. A turbulator includes a turbulator peak and/or a turbulator valley, which has a turbulator slope, and the turbulator peak and/or turbulator valley has a turbulator axis that is generally perpendicular to either the first fluid flow direction or the second fluid flow direction. The respective slope angles are generally 25-65 deg. relative to build-axis, thereby resulting in improved surface roughness and uniformity control during the build process.
