I thought the comparison with home DTP software was very astute. This paragraph especially so:
"Creating good 3D computer models is as hard to do today as designing good magazine layouts was in the 1980s. Sure, the software tools were there, but what was lacking in many of their users was the skill to use them effectively. That’s just as true of 3D printing now.
Are we about to see a mass of 3D printed objects that are the poorly designed equivalents of all those desktop published pamphlets full of enormous drop-capitals, unsubtle drop-shadows and clip-art? So many 3D printed objects are already becoming clichés of the form."
