Apparatus and method for three dimensional model printing

A method for three-dimensional printing of a three-dimensional model utilizing a printing head having a plurality of nozzles along a longitudinal axis, the method comprising the steps of:

• positioning the printing head to a first pre-selected position;
• selectively dispensing interface material in a first layer from said printing head;
• re-positioning said printing head to compensate for blocked nozzles to a subsequent position, said subsequent position being offset a distance of at least one nozzle along said longitudinal axis from said first pre-selected position and being a vertical distance above said first layer, said vertical distance being equal to the thickness of a subsequent layer of dispensing material;
• repeating said step of selective dispensing in the subsequent layer;
• and
• repeating said steps of re-positioning and selective dispensing in the subsequent layer until the three-dimensional model is completed.
