Average
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
prototyping .
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.
The report, which can be downloaded
for free, is available here.
Printing and sharing digital photos is easy. But what if, instead of printing a photo on a coffee cup, you want to print just the coffee cup? With a different kind of printer, called a 3-D printer, you can do exactly that: produce three-dimensional objects that you design yourself. And the selection of such printers for home use is growing while prices are rapidly falling. In May, the newest of these inkjetsuperstore hp 56 ink cartridge.
By refining topologies and using new fluid technology, Moog's new peak sine drive controller increases available power without increasing controller volume.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
