Method for producing a manhole component or shaft section with a functional contour, comprising generating data sets representing the component from various sources, including a library of standard sections, object questionnaires, and data models based on exchange formats like ISYBAU XML. The data sets are then used to control a 3D printing process, including specifying milling paths, tool selection, and auxiliary structure design, to produce the component with precise geometry and surface finish.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
