The US Patent and Trademark Office has approved Apple's patent application for a 3D printing method using triangular tessellation. In another embodiment, the triangles making up the triangular tessellations are dynamically sized triangles. The method replaces the uniform internal infill patterns formed on the inside of an object during 3D printing with different-sized triangles to reduce the risk of cracking in the product. Apple filed its patent application back in September last year but it was only recently granted provisional approval.
