When it comes to 3-d printing I see two attitudes around me:
(1) People who are involved with "making" from a blue collar standpoint think that "3-d printing is cool but the quality of the product is subpar" (2) People around the engineering department at my local Uni who 3-d print everything they can
A lot of the 3-d printing market targets type (1) and enthusiasts. If those enthusiasts were inkjet enthusiasts they wouldn't mind getting prints spoiled with an ink explosion 5% of the time.
