Press Release: CAD Engineering Standard for additive manufacturing

02.04.20203dprint, 3dprinting, additive, additivemanufacturing

Exact geometry without deviations
The sophistication of this future-oriented tool is that the CAD data of all common systems such as Catia, NX, SOLIDWORKS, Creo, STEP or JT are read with all manufacturing information (PMI) and processed as exact B-Rep geometry. This enables the inspection, repair and preparation of the 3D models according to CAD Engineering Standards. With common 3D printing tools, CAD models are triangulated, i.e. converted into STL, as soon as they are read in, making it impossible to repair the geometry without form deviations in reality. On the other hand, the exact geometry core of 4D_Additive eliminates deviations, since the CAD model remains based on the original geometry description right to the end. When slicing, which is carried out with multiprocessor calculation, vector graphics can also be generated as an option. Depending on the machine type, these can be processed directly as exact curves. As an output format, 4D_Additive supports 3MF, AMF and STL as well as all common slicing formats.

Innovative features
The new software has modern, easy-to-use graphics and innovative features such as 3D nesting as well as collision and distance control for automated and safe placement in the installation space. With the help of dynamic roughness analysis, the user can determine the optimum alignment of the components in seconds to generate the best possible surface. An additional module is used for the automatic generation of support geometry, which is particularly necessary for FDM and common laser sintering processes. The system's expertise database contains the usual machine data and information on the respective process, so that important parameters can be preset when selecting the machine. 

CoreTechnologie breaks new ground with a texture generation based on the exact geometry, whereby the transitions on the surfaces are defined very precisely and easily. Over 5,000 predefined textures are already available for the system. Particularly in combination with high-resolution processes such as HP JetFusion, impressive components are created that cannot be produced using any other process.

Automatic component search
The Partfinder is also a new tool from CoreTechnologie and helps companies to explore the potential of additive manufacturing for themselves. The software reads CAD files directly at file system level and analyzes geometry, design elements, PMI and attributes. All information is stored in the internal database. Finally, these information will be filtered according to the desired search criteria using a freely definable search mask and will be clearly displayed in a list with a 3D graphic and all relevant information. Multiprocessor calculation allows components with 3D printing potential to be found quickly and easily, even in large databases.
