The new version of the 4D_Additive software from CoreTechnologie enables the use of exact B-REP CAD data of all common native and standard formats for the preparation of 3D printing jobs, but it also allows the generation of repaired and optimized STEP models. With version 1.4, users can save the repaired and optimized CAD data as exact STEP geometry. It is also possible to save the automatically generated support structures as exact STEP models and then process them further in a CAD system or use the support structures for FEM analysis.
By using exact models imported as STEP as well as other common native formats such as CATIA, NX, CREO and Solidworks, this tool enables accurate analysis and repair of models. Up to now, mainly triangulated STL models have been used for 3D printing, which can only be an approximation to real CAD geometry. With the B-Rep core of the software, models can not only be repaired with accuracy, but can also be adapted specifically for 3D printing through modeling functions. By this means, offset surfaces can be generated in the software for subsequent over-milling of fits or diameter changes for Ensat bushings.
Higher accuracy and less memory space
An advantage of the exact geometries compared to STL models is, in addition to higher accuracy, a lower memory space for the data is needed. Thus, extensive building platforms with hundreds of parts are stored in a compact file size. The Manufacturing Software 4D_Additive enables a 3D printing process, i.e. the inspection, repair and preparation of models in accordance with the CAD engineering standard which has long been established for other common production processes.
In addition to the innovative texture module for surface refinement and automatic labeling of parts, the software also comprises repair and modeling functions. Automated part alignment and intelligent nesting functions with multi-processor calculation enable reliable and fast filling and optimum use of the build space, for all common machine types. Special analysis functions ensure collision safety, optimum heat distribution and production-oriented component design and complete the software in terms of a seamless additive manufacturing process.
