The MIT trademark is apparently "3DP" - not "3D Printing." As I
understand it, this is because you cannot grab a simple descriptive term or
phrase out of the English language and claim it as your own property. In
order to have a valid claim on a trademark, you must create something new and
ADD it to the language. [The language comes first, the commercial venture

Personally, it seems to me that "3D Printing" or "Three-Dimensional Printing"
is a very simple, direct, and logical term for the future device that people
have been discussing here. Guess we just have to wait to see what term has
enough appeal to take over. [No offense, please, but "Rapid Prototyping" is
just one important part of the broader "three-dimensional hardcopy" concepts
which underly the long-term "popular" potential - turning 3D computer
information into physical reality.]

"beam me up Scottie" image (or is that from another fantasy?) of live people
being "teletransported" (?). Lacking any other theory of explanation, I
could not resist my polite, if strong, clarification.

Regarding the dual laser methods - Even if the various technical problems are
solved, there seems to be little prospect of avoiding liquids. For success
in a mass market, a method must be DRY and CLEAN (in addition to easy and
