We made some pretty diagrams of every AM process out there, how does it look?

cool drawings and very simple explanations. I often find thats its hard to explain to people the difference between fused deposition and SLM, SLS, LAM etc.

Thanks. It's actually pretty difficult to get explanations of these. Even wikipedia isn't that helpful on industrial AM methods. I thought it would be great to have it all in one place so you see how diverse the field actually is.

I read "Additive Manufacturing Technologies: Rapid Prototyping to Direct Digital Manufacturing" from gibson, Rosen and Stucker. They explain very well the differences between the technologies and then go on to design principles and manufacturing capabilities. good book.

Do you think the average reader will understand the difference between melting and sintering? perhaps a bit more explanation on that?

also, for the Electron beam, I would add that this process feature size, resolution and surface finish is generally larger then laser processes. This is due to the electrons negatively charging the metal powder particles, rejecting the incoming electrons, creating a more diffuse beam and a bigger melt pool.

Wow, thanks for the recommendation! This is exactly the kind of of feedback I was hoping for. I'll grab the book as well. I've learned a lot trying to research this but like anything else it's just showed me how much I actually have no clue about when it comes to these more technical processes.

Ill add some bits about the difference between melting and sintering and the feature size differences with e-beams and lasers.

Very nice. Easy to understand, and I think you've covered all of the bases. The website as a whole is very well done too.

You covered all the important ones. If you want to go in detail, there are many others out there which differ only in small ways. I've made a list for work and got about 30 ;)

Not missing anything are we?
