The German-French software manufacturer CoreTechnologie (CT) is introducing version 1.8 of the 3D printing software 4D_Additive. With the new Build History, a powerful automatic repair of triangulated data, and enhanced lattice functions, the preparation of components for various additive manufacturing processes becomes significantly faster and more convenient. A highlight of the current software version 4D_Additive 1.8 is the new Build History Tree ...

The More Transparent Path to the Printed Part

... because, following the example of the construction tree in modern CAD systems, all steps in build preparation are clearly and comprehensibly displayed in a list. Each processing step is documented and can be accessed directly or step-by-step at any time, according to CT. Users can review and modify all parameters of each processing step at any time. This results in more transparently documented workflows, faster implementation of changes, and significantly reduced preparation times—especially for modifications. Users can import and process models either as exact CAD geometry or as triangulated data. For particularly fast data preparation, the exact CAD geometry can be selectively converted into triangulated models and then optimized using the new automatic repair. This allows 4D_Additive to combine the precision of native CAD data with the high processing speed for repairing triangulated models.

Faulty Data Automatically Optimizable

The automatic correction of triangulated models has been significantly expanded, as emphasized by CT. The new "Advanced Automatic Mode" of the healing tool automates a previously manual sequence of various repair steps. With just one click, models with severely flawed or low-quality initial data can now be largely automated, corrected, and optimized for further build preparation. This reduces manual interventions and particularly accelerates the processing of external or qualitatively problematic 3D data, according to CT. Additionally, so-called stiffeners have been newly introduced. These reinforcement structures stabilize thin-walled and large components during the manufacturing process and counteract unwanted deformations. The lattice design can be specifically adapted to the geometry of the component and functional requirements. This opens up additional possibilities for material savings and the development of functionally optimized lightweight components.
