So far, I've sent three OBJ files to get quotations.  In each case, there's been a problem.  The first two were transmapped hair related.  These guys were great in explaining that, because there were certain sections of the hair that had zero thickness, the printer would not be able to distinguish where to start and stop.  The result would have been as extreme as having the head literally fall apart.  Surprisingly, the last attempt, which was my own RobbyBobby character in chaps and vest, would not work because the said chaps and vest are single sided meshes...again, no thickness...no print.  That one surprised me and now I'm wondering if I'd run across that same problem with other clothing items.  So, the next attempt, which should have been last night, but I had problems starting up Poser for some reason, will be NRBNTNSANH (Naked RobbyBobby, No Temple, No Sword And No Hair).
