A static mixer created using an additive process is disclosed. The static mixer is enabled to homogenously blend two fluids flowing in a pipe. The static mixer exhibits zero contact angle in relation to the two fluids being mixed within the pipe. The static mixer exhibits a first contact angle with the first fluid and a second contact angle with the second fluid. The first contact angle is either between 0 and 30 or greater than 85. The second contact angle is either between 0 and 30, or greater than 85.
