Abstract Scope |
The standard digital workflow for generating input data for additive manufacturing (AM) processes consists of an ad hoc and pragmatic approach of modeling representations. Typical downstream representations employed are the result of the CAD model not being directly suitable for use. Derivative models are generated to fill this need and to solve critical issues with flaws in the CAD data, but as a result introduce many other problems affecting both the digital process as well as the precision of the final AM print.
The Kansas City National Security Campus (KCNSC) is working towards a solution to eliminate these problems by investigating the value provided by a smooth, accurate, and watertight geometric definition within the native CAD platform. To do so, KCNSC is partnering with nVariate, Inc. to utilize their patented technology to create natively watertight models, and explore directly slicing the watertight CAD models for use on the AM machine. The Department of Energy’s Kansas City National Security Campus is operated and managed by Honeywell Federal Manufacturing & Technologies, LLC under contract number DE-NA0002839. |
