prototype part costs drop 9.2 to 36.9 percent when parts are consolidated into single
builds, according to a new benchmark study released by T. A. Grimm & Assoc.

"Our goal is to put real-world data in the
hands of those interested in evaluating 3-D printers so that they can make informed
decisions. In the report, we show which system has an effective material cost
of $3.57/cubic inch and which has a cost of $25.05/cubic inch. The investigation
also reveals discrepancies in time as large as 17 hours for a single prototype.
These are details that are important to prospective users," says Todd Grimm,
president, T. A. Grimm & Assoc.
all aspects of dimensional accuracy, 3-D scanning technologies were used to
measure the 3-D printed parts. High-resolution white light scanners captured up
to two and a half million points on each prototype. These dense data sets were
then translated into color maps and statistical charts to visually describe
