The US Patent and Design Office has approved Apple 's patent application for a 3D printing method using triangular tessellation . “In one embodiment, the triangles making up the triangular tessellations are fixed-size triangles. The method replaces the uniform internal shape patterns formed on the inside of an object during 3D printing with different - sized patterns to reduce the risk of cracks in the object . This results in faster printing because the print head only needs to move forward to produce the triangle ##s , rather than backwards and forwards , according to the patent application .
