  • Patent number: 11980307
    Abstract: A serving tray comprised of at least one synthetic material and an insert which provides a non-slip top surface of the serving tray. The textured relief is preferably made of thermoplastic polyurethane (TPU) which allows a glass or other item to be placed on the serving tray without the item sliding or slipping while the tray is in motion. As the tray is being fabricated, the TPU is mechanically bonded with the top surface of the tray while a textured relief is simultaneously defined into the top surface. The textured relief provides adequate frictional force to an item being placed on the tray so as to substantially prevent its lateral movement. The tray also includes an inner support structure disposed on its inner surface. The inner support structure provides an upward facing edge which allows a plurality of trays to be easily and efficiently stacked or nested on one another.

  • Patent number: 11926105
    Abstract: According to some aspects, techniques are described for generating support structures that may be easily removed after fabrication yet provide sufficient structural support during fabrication. In some cases, the techniques may include tuning an extent to which pillars of a support structure are interconnected to one another in regions proximate to the part. In some cases, the techniques may include fabricating very small contact structures, referred to herein as “hair” supports, in regions of a support structure where it connects with the part. In some cases, the techniques may include generating support structures that comprise obliquely-angled tips, which allow forces during fabrication to be applied in a preferred direction even when the support structure does not make a connection to the part in the preferred direction.
