Four 3D printable Portland cement-based mix designs were developed. A method for determination of compressive and flexural strength of 3D printed prisms (taking into account the effects of 3D printing on the surface of the object) and a comparison to molded samples are presented. Prisms prepared by 3D printing show interfilament voids but have nevertheless mean values of compressive strength which are comparable to molded prisms. Flexural strength was strongly affected by surface irregularities introduced by manufacturing by 3D printing and is in every case lower as for molded specimens. In most cases, the variation of strength values of 3D printed test specimens was considerably higher than for molded equivalents. The presented Portland cement-based mix designs include a mix with the use of an ordinary Portland cement (OPC) clinker mixed with a calcium sulfate addition which is lower than in standard OPC which was also successfully utilized for 3D printing. This mix performed best in compressive and flexural strength. The developed materials were further examined by slump test and ultrasonic wave velocity.
