What does “SFF” mean?
SFF stands for Solid Freeform Fabrication – basically an umbrella term for 3-D printing, Rapid Prototyping, additive manufacturing, etc. – building things by having a machine deposit material under computer control. Some people prefer “Rapid Prototyping”, but since we are trying to use it for more than just “prototyping”, I kind of prefer “fabrication”, and since it isn’t really that fast, we usually ditch the “rapid”. Maybe “Additive” is better? 3-D printing is actually a trademark of Z-Corp., so I shy away from that as well. See also Wikipedia definition and Castle Island RP/SFF reference site.
