Analyzing directed energy deposition and powder-bed fusion provides a thorough understanding of the extra machining necessary for a “near net shape” versus a “net shape” manufacturing process.
Powder-bed fusion is driving the hype for additive manufacturing right now, but it may not be the best answer. Directed energy deposition is a strong contender.
Be aware of the inherent manufacturing and design challenges that impact the dimensions and tolerances that you can (or cannot) achieve on an “as built” part.
