Problems solved by technology

A disadvantage of this fabrication technique is the speed with which three-dimensional solid objects can be produced
[0004] The use of additive manufacturing in high quality bearings or actuators is already limited
However, additive manufacturing offers endless possibilities

Embodiment Construction

[0039] Figure 1A A bearing 200 according to the present invention is shown (for example, shown in Figure 2A A sectional view of the inner ring 100 of the bearing 200 in . The inner ring 100 is a building block 100 according to the present invention and includes a raceway ring 110 having a raceway surface, and includes a first printing material 120 printed onto the raceway ring 110 . The use of the first printing material 120 provides a very flexible way of manufacturing the shape of the inner ring 100 of the bearing 200, wherein the first printing material 120 can have any desired shape. Using the substantially standardized raceway ring 110 as a starting product, a customized inner ring 100 can be manufactured relatively easily by adding the first printing material 120 . Using this additive manufacturing of adding printing material to a substantially standardized raceway ring 110 ensures a customized inner ring 100 with both high flexibility and high quality. exist Figure...

Abstract

The invention provides a building block (140) 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 comprises a first printed material (150) being printed via an additive manufacturing process, wherein the first printed material comprises a framework of a second material (155) different from the first printed material and at least partially embedded in the first printed material. This framework of the second material may be included in a hollow structure (157). 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.

Description

technical field [0001] The invention relates to building blocks for mechanical structures. The invention also relates to bearings, actuators and gearboxes. Background technique [0002] Additive manufacturing, or more commonly known as 3D printing, is a known manufacturing technique that produces three-dimensional solid objects from digital models. The process of additive manufacturing begins with the generation of a digital model by any known digital modeling method, for example using a CAD program. Next, the digital model is segmented into slices, where each slice represents a layer in the digital model where printed material should be placed. Each slice is fed into the additive manufacturing tool or 3D printer in turn, and the material is deposited by the additive manufacturing tool or 3D printer according to each slice, so that a complete three-dimensional solid object is generated layer by layer. [0003] In the early days of additive manufacturing, plastics or resin...
