Ivan Sentch is 3D-printing a 1961 Aston Martin DB4 on his Solidoodle desktop 3D printer, 4 inches by 4 inches at a time. The Auckland, New Zealand resident is about 72% done printing the body, and he expects to pay a mere $2,000 NZD for the plastic to make the plug — versus the $12k–$15k for a CNC-cut foam plug, which is what is normally used in replica car projects.
