We saw several messages regarding questions on the 3D SLA7000. Please 
Incs to explain. We are INCS, the largest service bureau in Japan and Asia
with 14 systems (3 SLA 5000's, 3 SLA 500s, 4 250s, 1 3500 and one Actua.)
We are one of the other first site of the new SLA-7000 Production
The machine was delivered and set up only a few days ago and is already
running very well.
We had done several benchmarks with our other three SLA-5000 machines.
We wanted to believe the speed and quality numbers that 3D Systems had said
the machine could do. But we were not so sure. So, we have done six medium
sized parts during the first day.
We used the new Lightyear software, and ran real customer data on the
SLA7000 with the fast Build style at 0.125mm and simulated the exact style
at .025mm. We compared this with Actual build times on the SLA 5000.
Please note that the 7000 can build parts with .025mm layers faster than the
can build with .15mm layers. Lightyear was also much faster as you can see
and very easy to use. 3D tells us that the final version of Lightyear will
be even faster. Lightyear accepts .STL data just like Maestro but you only
have to work with one interface on one screen. Very Easy.
The software was run on the following configurations:

IRIX 6.4, R10000, 195MHZ
640MB RAM, 9.1GB Disc

3D Lightyear
Windows NT PII 450MHZ x 2
512MB RAM 9GB Disc

SLA5000 Laser Power 200mW
SLA7000 Laser Power 230/800mW
