If you're new to the world of additive manufacturing (AM) and feeling overwhelmed, this free resource is a lifesaver! I stumbled upon it while researching 3D printing basics, and it quickly became my go-to guide.

The book does an outstanding job breaking down complex concepts into digestible chunks. What I love most is how it clearly differentiates between rapid prototyping and true additive manufacturing - something even seasoned makers sometimes confuse!

While using this resource, I particularly appreciated the practical applications section. It helped me understand how AM is revolutionizing industries from healthcare to aerospace. The design implications discussion saved me from making several rookie mistakes in my first 3D printing projects.

The companion OU course mentioned in reviews is indeed valuable. I found the combination of book learning with practical course exercises created a perfect learning balance. It's rare to find such comprehensive educational materials available for free.

My only critique? The content could delve deeper into specific AM techniques for intermediate learners. But as an introductory resource, it's absolutely brilliant and has earned a permanent spot in my maker's reference library.
