Worldwide consumer electronics company Apple. Inc reveals a new method based on triangular tessellation to print 3D models. The method was patented on 23 October, 2018. The company has stated that the sole inventor of the 3D printing is Michael R. Sweet, who is the Senior Printing System Engineer at its office in Canada.
Sweet revealed that in one way of 3D printing, the triangles that makes triangular tessellations have fixed size. In another configuration, the triangle making up triangular tessellations can be of different size. Small triangles can be utilized for developing an object’s edges. Whereas, larger triangles are required to construct areas where backing is not the key objective.
Distinctive Benefits in Infill helps maintain Rigidity of 3-D Printed Surface
The key aspects on which patent focuses are internal infill and surfaces. The infills are the small patterns on the inner side of the object which helps in retaining stiffness. Most often the infill is pretty simple and consists of drawing shapes or squiggles, which help the model to retain its shape. This may expose the surface to brightness and cracking. The method developed by the company changes the whole infill process. The similar system is applied on the side of the print to appropriate clean surface.
The patent does not reveal that the Apple is developing a 3D printer. It means that the researcher in the Apple has developed a better and faster method for 3D printing, which will open new avenues in designing parts of the 3D printer.
