Costs Vary Widely for 3-D Printers

Averageprototype part costs drop 9.2 to 36.9 percent when parts are consolidated into singlebuilds, 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 100images, charts and tables comparing seven 3-D printers widely used for rapidprototyping .

Thebenchmark measures the performance of Alaris30, Designjet 3D, ProJet SD 3000,SD300 Pro, uPrint, V-Flash and ZPrinter 310 Plus in terms of time, cost andquality.

"Our goal is to put real-world data in thehands of those interested in evaluating 3-D printers so that they can make informeddecisions. In the report, we show which system has an effective material costof $3.57/cubic inch and which has a cost of $25.05/cubic inch. The investigationalso 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 presentall aspects of dimensional accuracy, 3-D scanning technologies were used tomeasure the 3-D printed parts. High-resolution white light scanners captured upto two and a half million points on each prototype. These dense data sets werethen translated into color maps and statistical charts to visually describepart quality.
