| Abstract Scope |
In a prototyping and experimental facility time is often the biggest hurdle in manufacturing, so being able to create hardened tool steel punches for forming in a way that can be done rapidly and iteratively is attractive. The authors have identified additive manufacturing (AM) as a potential solution to this problem especially in applications related to deep draw forming and hydro-forming. 4340 steel is used in forming tools and is a good choice for use in laser powder bed fusion based AM. We show that there can be significant time saving advantages to this process over conventional machining when dealing with complex tool geometries, as well as material properties that can only be achieved through AM such as a different micro-structure in the tooling at its working surface than throughout the rest of the punch. |
