"Legitimate Use" includes the intended use as the program is designed. As it is worded in the EULAs I have seen and, since most redistributors have EULAs that specifically protect copyright on 3D printing, it is best to assume that reproducing the geometry in a form other than what is specifically provided for by the program is an illegitimate use. Also, it is absolutely forbidden to redistribute the geometry in any form, so no 3D objects could be sent, for instance, to a third-party 3D printer without specific permission from Smith Micro or the original artist, if copyright is reserved. (IE: Makehuman copyright owners may, for instance, allow for this use if the figures are derived from their software. However, that licensing may not extend "through" Poser to the end-user. It may stop at Smith Micro and Smith Micro may have a "limited use" agreement with the copyright owners of Makehuman.)
