The present invention is directed to a 3D-printed tire segment model having a tread portion comprising a plurality of grooves, ribs and/or tread blocks, and a plurality of blades extending out of the ribs and/or tread blocks, wherein the tire segment model is made of a 3D-printed polymer. Moreover, the present invention is drawn to a method of making a tire mold segment, including the step of 3D-printing the above tire segment model with a polymer.

Tire segment model and a method of making a tire mold segment

Tire

An advanced tire mold has been developed which offers the advantages of reducing the level of whiskers on the surface of the tire, reduces sticking to the mold, and which facilitates enhanced gas removal. This tire mold includes a mold segment having an inner side for contacting the uncured tire, an outer side opposite to the inner side, and a plurality of vent passages which allow gas to pass from the inner side of the mold segment to the outer side of the mold segment, the vent passages comprising vent slots, wherein each vent slots have an inlet at the inner side of the mold segment, and wherein the vent slots taper from the inlets to the outer side of the mold segment. This tire mold can be comprised of multiple mold segments which can be utilized in a tire curing press.
