Patent number: 10436252Abstract: The invention provides a building block for a mechanical construction. The invention further provides a bearing, an actuator system, a housing, a hub, a mechanical connector and a gear box. The building block includes a first printed material being printed via an additive manufacturing process. The first printed material provides a framework of a second material different from the first printed material and at least partially embedded in the first printed material. The framework of the second material may be included in a hollow structure. Alternatively, at least a part of the framework of the second material may constitute at least a part of the inner wall of the hollow structure. The framework of the second material may be pre-fabricated or may also be generated via the additive manufacturing process. A benefit of this building block is that it allows an increase of strength while limiting the overall weight.Type: GrantFiled: December 18, 2014Date of Patent: October 8, 2019Assignee: Aktiebolaget SKFInventor: Alejandro Sanz
