Printing Method and Printing System

A printing method for forming a continuous strand of building material for 3D printing of a structural part via a printing system,

• wherein the printing system comprises:
• a printing apparatus, wherein the printing apparatus is designed to dispense building material out of the printing apparatus and to shape the building material to form a strand of building material, and
• a discontinuous building material pump, wherein the discontinuous building material pump is designed to discontinuously convey building material for purposes of discontinuously dispensing conveyed building material out of the printing apparatus,
• wherein the printing method comprises the steps of:
• a) discontinuously conveying building material via the discontinuous building material pump and discontinuously dispensing conveyed building material out of the printing apparatus and shaping conveyed building material via the printing apparatus;
• and
• b) discontinuously moving the printing apparatus during the discontinuous conveying and the discontinuous dispensing such that the dispensed and shaped building material forms a continuous strand of building material.
