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.
Inc. The free 60-page report,
available in both North American and European editions, includes more than 100
images, charts and tables comparing seven 3-D printers widely used for rapid

The benchmark measures the performance of Alaris30, Designjet 3D, ProJet SD 3000, SD300 Pro, uPrint, V-Flash and ZPrinter 310 Plus in terms of time, cost and quality.
"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.
To present 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 part quality.
