Abe Reichental President & CEO

We continued to expand our
3Dproparts™ services by:

• Acquiring Provel in Italy

• Consolidating and adding capabilities and
capacity as required

We expanded our personal and
professional 3D printer reach
and technology breadth by
acquiring Bits From Bytes and
launching several new ProJet™
printers at Euromold

We grew our healthcare solutions
revenue and installed base year
over year and received production
printer orders for delivery in future
periods

We expanded our reseller
channel and grew personal and
professional printer revenues by
103% over the comparable 2009
quarter

Recent Developments

We entered the first quarter of 2011 with a strong sales funnel and
we expect revenue growth over the prior year quarter for the first
quarter of 2011

We expect strong demand for our personal, professional and
production printers helped by our expanding channel and expanding
portfolio

We expect 3Dproparts™ revenue growth from a combination of
organic growth and additional acquisitions

We expect healthcare solutions revenue growth benefiting from our
expanding solutions portfolio and growing installed base

Revenue Outlook

Gross Profit and Operating Expenses Outlook

We expect our gross profit margin to improve over time but expect it
to be susceptible to:

• Potential adverse printers mix in favor of lower margin personal printers

• Impact of Integration costs of acquired businesses

• Remaining V-Flash® drag that is expected to decrease and end all together during
the second quarter of 2011

We expect operating SG&A expenses for 2011 to be in the range of
$47.0 - $50.0 million:

• Inclusive of our anticipated litigation expenses as we currently understand them

• Increased operating costs associated with 3Dproparts™ acquisitions we made thus
far

We expect R&D expenses for 2011 to increase and be in the range of
$11.5 - $13.5 million reflecting our expanding print engine portfolio
and planned new product introductions throughout the year

Our sales funnel remains robust and our backlog
reflects the strength of our business model

Our personal, professional and production printers
and print services are expected to generate
increased customer demand

Our business model is built around significant
recurring revenue components that generate
improved margins

We remain committed to our long-term growth
objectives and confident in our ability to provide
value to our customers and stockholders
