The invention relates to a concrete material applicable to 3D (Three-dimensional) printing and a preparing method thereof. The concrete material applicable to the 3D printing comprises the following components in parts by weight: 100 parts of 52.5#cement, 120-200 parts of sand, 0.9-1.1 parts of chopped glass fibers which are 1-2mm in length, 3.9-7.9 parts of chopped glass fibers which are 20-30mm in length, 0.05-0.15 part of HPMC (Hydroxy Propyl Methyl Cellulose) and 30-45 parts of water. The concrete material provided by the invention changes the fixation technique that the traditional concrete must be stacked and sized through reinforcements; bonding capacity of the concrete is increased by using alkali-resisting glass fibers with different length specifications; according to the concrete material prepared by the preparing method, flexibility of glass fibers is sufficiently utilized and the chopped glass fibers with length of 1-2mm are uniformly mixed, so that building materials printed with the obtained concrete material has good compression resistance and anti-tensile strength, and whole performance of the products can be guaranteed and improved; strength and service life of the concrete material are greater than those of the traditional reinforce concrete material; the concrete material can be recycled, so that pressure of the traditional building materials to the environment is greatly reduced.
