Abstract Scope |
ORNL Slicer is a slicing engine and graphical user interface (GUI) developed for large scale additive manufacturing at Oak Ridge National Laboratory. A distinct version of it is being developed for the wire-arc robotic- based technology. The software imports .STL files and slices them into layers to generate robotic toolpaths in GCode. As the additive manufacturing technology advances and adapts to the geometrical complexity and customized design, many features have been added in the Slicer to address the complexities so that the 3D printing is optimized in characterizing geometric features with minimum mechanical and thermal stress. To help the final toolpaths to achieve the best printing quality, many post-slicing editing features have been added as necessary supplements to allow one to modify features locally. This presentation will bring a few examples of wire-arc parts to illustrate the features in either the engine or the front end that meet those challenges. |
