Custom parts services gross profit margin increased 1,290 basis points over the comparable 2010 quarter, but decreased 690 basis points sequentially on a seasonal revenue shortfall of higher margin 3Dproparts™ Italy revenue and higher Quickparts® revenue at lower margin.

The company ended the first six months of 2011 with $79.0 million of available cash and cash equivalents. During the first six months of 2011 the company generated $6.2 million of cash from operations, used $29.2 million to fund strategic investing activities and completed a common stock offering with net proceeds of $62.1 million.

"We remain focused on democratizing access to affordable and viable 3D content-to-print solutions for professionals and consumers alike. We believe that the marketplace for our products and services is largely underpenetrated and that our diversified portfolio makes us more attractive to broader audiences. While the rapid growth rate of our custom parts and printers revenue outpaced our margin expansion rate for the quarter, we remain optimistic about our future and believe that we are on track to achieve our long-term target operating model," concluded Reichental.
