This paper deals with a combined additive and subtractive process for metal parts production. Starting from the configuration of commercial LOM machines, a new machine design is proposed for metal parts, equipped with ATC with various form tools and capable of adaptive slicing. Then, the attention is focused on the adaptive slicing algorithm. The advantages of the proposed solution and its application, in comparison to existing solutions are its improved aesthetic appearance of the part. Also, this new methodology in its final form would result the faster product with better accuracy.
