3d printing of cementitious material with dynamic control

A 3D printing system for printing of cementitious material, comprising:

• a mixer configured to mix the cementitious material;
• a plurality of bins configured to hold and supply material to the mixer;
• a pump configured to provide the cementitious material to the deposition nozzle;
• a deposition nozzle configured to extrude cementitious material, receive materiel at the nozzle, and wherein the deposition nozzle comprises a mixing chamber and an auger for mixing at the cementitious material at the nozzle;
• a heating element in communication with the deposition nozzle, the heating element configured to transfer heat to the cementitious material within an interior portion of the mixing and deposition nozzle;
• and
• at least one sensor configured to generate temperature readings for the cementitious material;
• and
• a controller coupled with the at least one sensor, the pump and the bins, and configured to receive the temperature readings, and control the pump, the amount of material being supplied by the bins, the volume of the material received at the nozzle, and the heating element so as to ensure that the hardening process of the cementitious material is optimum.
