The Additive.Designer is a versatile and customisable software solution for easy data preparation to handle complex components in additive manufacturing, providing a personalisable, intuitive user interface with a managed workflow. Two of the most important advantages of the software are cost reduction through error avoidance due to the good plannability of the build job and the resulting higher quality of the manufactured components. The data preparation process can take into account all factors from the selection of the machine to the post-processing of the component.
