Gross Profit and Operating Expenses Outlook
We believe that we can further enhance our operational effectiveness
and optimize our operating costs.
q We expect our gross profit margin to remain stable despite:
q Potential adverse systems mix in favor of lower margin printers and integration period of
acquired businesses and
q Continued negative 2-4 percentage point drag from V-Flash® through the first half of
2010.
q We expect SG&A to be in the range of $27.5-31.5 million for the remainder of 2010:
q Inclusive of our anticipated litigation expenses as we currently understand them
and
q Increased operating costs associated with 3Dproparts™ acquisitions we made
thus far.
q We expect R&D spending for the remainder of 2010 to be in the range of $7.5-9.0
million while keeping pace with our planned new product introductions.

29
Bottom Line
q Our sales funnel remains robust.
q Our Parts, Printers and Production Systems are
expected to generate increased OEM demand.
q Our business model is built around significant,
recurring revenue components that generate
improved contribution margins.
We remain committed to our long-term growth objectives and confident in our
ability to provide value to our customers and stockholders.

The average growth of 3-D printer unit sales from 1996
through 2008 was approximately 40%.
The market is well-positioned for further growth because of
the wide appeal of 3-D printers priced at less than $15,000.
Gartner believes this continuing demand bodes well for the
longer-term prospects of the 3-D printer market.
Gartner estimates shipments rise to 85,000 units in 2015.
