Hi RPers,

I have been working with Stratasys products now for many years, At RP
Solutions we run 2x1650's 1x2000 and 1x8000 with more on the way. I think I
can vouch for their ease of use, reliability and speed of build.

We have always had good service from Stratasys and their UK agents Laser
Lines Ltd.
The FDM technology has proved ideal for producing functional prototypes in
production materials and our customers are very pleased with the results.

Functional prototypes in ABS, Polycarbonate and PPS, what other RP system
can build all these?
