Bathsheba's thoughts on Chuck Hulls favored choice of verb "form" in his
patent is suggestive to the idea that growing a model from a UV cured resin
with a laser over a moving Z table is more like growing a model in a
continuous process and not printing it.
Patents are written specifically to describe ownership rights to an idea.
If printing was intended, it would have been written. Forming a 3D object
is a valid idea. It may have been the better choice. Looking at other 3D
technologies, many are forming 3D objects. The fastest machines are truly
continuous form makers. Is the term, 3D Printing securely established in
our culture? Is there room for 3D Forming?
Forming Manufacturing process? Continuous Form Manufacturing. I kind of
like this description for a new technology.

It's so very nearly present in Hull's stereolithography patent -- the words
"three dimensional" and "printing" are both used but never in the same
sentence. I can see how, reading that a few times, the phrase might
coalesce in one's mind.

It's interesting to me that although "print" is used a few times, Hull's
verb of choice is clearly "form", which is used to describe the overall
process many more times and in more immediate contexts. In all the
bickering I've seen about what the vernacular term would be, I think I
never saw that option considered. Yet it wouldn't have been a bad choice
-- I feel like there must be a nearby alternate timeline where it prevailed.
