Additive Manufacturing with Sheet Lamination
By: Timothy W. Simpson
No longer limited to paper, Sheet Lamination bonds sheets of material together to form an object. Companies are now expanding to different materials for sheet lamination, exploring the growing possibilities of a process that started with gluing and stacking hundreds of colored sheets of paper together.

Three Cool Uses for Directed Energy Deposition
By: Timothy W. Simpson
Most machining professionals don’t like to admit that they ever make mistakes, but every now and then wouldn’t it be nice to have an “eraser” to go back and repair a gouge or fix a nicked edge? Or maybe you took off a bit too much material on that last machining pass and you’d like to add it back? Well, directed energy deposition (DED) enables you to do that and more.

What Is Directed Energy Deposition?
By: Timothy W. Simpson
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.

Additive Manufacturing for Large Parts
By: Timothy W. Simpson
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.
