US Patent 10105905 Using triangular tessellation in 3D printing

Systems, methods, and computer readable media to improve the operation of three dimensional (3D) printer systems are described. In general, techniques are disclosed for providing improved (smaller) print times and reduced consumption of material for a given end assembly. More particularly, a print-head motion exhibiting a triangular support pattern (aka triangular tessellation) is shown to be more efficient than circular print head motions used in current 3D printers in terms of speed and/or material usage.
