Engineering software developerCoreTechnologiehas developed a new nesting function within its4D_Additive基于人工智能（AI）算法的打印准备程序。
The AI ensures an even arrangement of parts in the build space during nesting via automated intelligent behavior and machine learning. Through this, the technology enables complex nesting tasks to be independently processed and simulates programmable decision-making structures.
CoreTechnologie’s 4D_Additive software
The 4D_Additive software is built on a boundary representation (B-rep) file foundation which, when compared to the more widely used STL format, represents solids more precisely with a set of flowing surface elements. B-rep allows for highly accurate model repairs while enabling a set of modeling functions that aid in the 3D printing process. Users can upload 3D models from common CAD file formats and prepare them for printing using the 4D_Additive software.
In September, CoreTechnologieadded the ISO-recognized STEP(产品模型数据交换标准)file format to its 4D_Additive software, which facilitates CAD file interchangeability between unrelated CAD systems. Last month, the company released another update for the software which allowed users to quickly and easilycreate latticed parts.
4D_Additive has CAD data interfaces for all B-Rep native and standard formates in addition to common 3D printing formats such as STL and 3mf.
优化的组件嵌套
The new nesting module integrated into the 4D_Additive software is built upon a “pack and optimize” strategy. This ensures maximum filling of the installation space and evenly distributes the material to be printed, in turn facilitating constant slice surfaces.
使用AI技术，该程序旨在通过预先定位后自动填充包装空间中的空区域来模仿经验丰富的用户的行为。结果，建筑空间均匀地填充，并避免了热巢。
除了智能嵌套功能外，Coretechnologie还提供了进一步的功能，可以在整个打印过程中优化组件中的热量分布。该软件分析了所谓的“大型区域”，以识别具有较大材料量的有问题的区域，并将其标记为用户。使用程序的空心和晶格功能，可以在必要时将这些区域挖空并用内部支撑结构加固。然后可以自动创建孔和盖，以使从空心部分内部清除粉末。
3D print preparation
For those seeking to optimize the design of their 3D printed parts, there are multiple print preparation software offerings available. In addition to 4D_Additive, CoreTechnologies’ software portfolio includes its 3D_Evolution, 3D_Analyzer, and 3D_Kernel_IO SDK formats.

Elsewhere, 3D printing startupTOffeeAMraised $1 millionto fund the development of itsaward-winningtopology optimization software.
