Master thesis – STL files to CAD format for topology optimized structures

Additive manufacturing, AM, also commonly known as 3D printing, is an advanced manufacturing process. At Siemens Energy AB we use mainly an additive manufacturing method called PBF-LB that welds metal powder layers together with a laser to create three-dimensional objects. The additive manufacturing process can create geometries with complex features and small internal channels, that the conventional manufacturing methods find problematic and expensive to produce. The AM technology possibilities to manufacture complex geometries also enables new design methods such as topology optimization (TO). By using TO, it is possible not only to minimize the amount of needed material but also create a design that also fulfill other functional demands in the best possible way for the final component.

As for all new technologies there are challenges to overcome, and in the case of TO the converting of TO-geometry to CAD format is one. The converting to CAD format is important to be able to describe and handle the topology optimized geometry together with other geometries in the same system.

This thesis aims to develop a practical method to convert 3D geometries from STL-format to a CAD geometry in NX.

The student will be hired by Siemens Energy.
