to the SLA500 Product Page

FAQ's 
1. Do I have to change resin ?
 Yes, RPC 100ND &
Somos 7120, 8120, & 9120 resins, will work fine.

2. How long will my machine be down ?
 The install will take place within an 8 hour day. Most of our customers
drain the old Argon resin, and add the new Solid state resin, on the day prior.
This way the resin is at the proper temperature, prior to our arrival.

3. What is the spot
size ?
 The spot size can be set to the same size you have been using with your
Argon Ion laser.

4. Is your warranty "prorated" ?
 No ! You do not have to pay twice, for one laser.

5. Is this the same solid state laser technology that 3D Systems currently uses?

6. What is the cost of a replacement laser, after the warranty has expired ?
 Laser "#2", will cost
$38,500.00 + travel expenses. This laser will have
the same warranty as the first laser; 1 year / 5,000 hours.

6.1 Cost of ownership / year, for the first 2 consecutive lasers:
 (worst case
scenario)
400 milliWatt laser will cost $63,000.00 / year, for (2) two years, or
10,000 hours
(typical scenario)
400 milliWatt laser will cost $31,500.00 / year, for (4) four
years, or 20,000+ hours

7. Is the cost of resin included with the purchase price ?
 No. Every one of our customers has a resin vendor already:
Vantico, Somos, or
RPC. We prefer to be only a laser vendor & service provider.

8. What is your warranty response time ?
 9 out of 10 times, we can provide technical assistance with in 4 hours.
(1 out of 10 times, with in 8 hours  we're only Human here) We stock lasers
& replacement parts, so your only a "FedX" away from our inventory. If
required, we can have an FE on site with 24 to 48 hours.

9.
How many of your solid state lasers have failed under warranty ?
 One. The RF driver failed in the power supply, it was replaced within 24 hours.

10. What additional AC voltage is required ?
 None, we use the existing
internal 220 or 110 AC voltage.

11. Are your solid state lasers watercooled ?

12. Do you provide technical assistance ?
 Yes we do, & free of charge. We provide technical support for customers
and noncustomers alike. On our solid state, (resin applications inquiries),
on the Argon lasers (for the SLA500's), and even on the HeCd's. We also
provide support on the other electronic equipment on the SLA. (eg. Vat
controller, zaxis driver, motors, AOM, scanners, scanner drivers, cpu, etc.)

13. How long have you been in business ?
 12 years. 10 years under Laser Innovations.

15. How many years has SpectraPhysics been in business ?
 35 plus years. The past 10 years have been concentrated on solid state lasers.

Graph 1 
The
average useable lifetime of an argon ion laser is approximately 5000
hours, upon which the average end of life power observed is ~100 mW.
In order to achieve the typical 300 mW at the vat, the average
laser needs to run at approximately 400 mW at the head to counter the
usual optical path losses, such as the external AOM found in the SLA500.
In order to maintain this desired level of performance, the tube
current must be raised over the life of the laser.
The
solid state laser has an initial output power of 400 mW and remains at 400
mW after 5000 hours. As an
added benefit, system throughput is typically improved due to the removal
of the AOM, which is no longer needed with this stateoftheart upgrade.
Additionally, there is no discernible increase in the utility
requirements such as those required by an aging argon ion laser to
maintain output power.
Using
the above parameters, how much more work does the solid state laser
execute over the argon ion laser in a 5000 hour period, prior to the need
of being replaced by a new argon ion laser?
Work
Executed by the Argon Ion Laser
Using
a bestcase scenario, the typical argon ion laser's performance
approximates Graph 1. Using
regular maintenance to counter typical degradation, power can be made to
remain somewhat constant in the first 1000 hours of operation.
After this point, the degradation can be approximated
mathematically by the curve of a parabola.
The total area under this combined curve is the work executed by
the argon ion laser (W=Pt). It is worth noting this is the point where the laser tube
current needs to be raised periodically to maintain the desired vat power.
In
order to find the area under the curve, we need to find an equation that
satisfies the curve. The
easiest way to produce an equation for the argon ion laser's curve is to
observe the inverse parabola, find an equation, then switch the x and y to
gain the equation of the curve.
E.g.:

Graph 2

Taking
the known points for the curve of the argon ion laser and interchanging
them create the parabola. E.g.:
V (1000,400) =>
V (400,1000). The graph that
is created from this process is an inverse of the original graph.
For inverse functions, the graph of either function is the
reflection of the graph of the other across the line y = x.
Once we find an equation for this parabola we can interchange the x
and y to generate an equation for the parabola’s inverse, which will be
the equation of the curve for the argon ion laser.
The
inverse of the argon ion laser’s curve produces a vertex V (400,1000)
and a point P (100,5000), (see Graph 2, Inverse Curve of an Argon Ion
Laser).
The
equation of a parabola is in the form y = ax^{2} + bx + c.
After completing the square in x and plugging in the vertex V (h,k),
the equation (xh)^{2} = 4p(yk) is produced.
Plugging in a point other than the vertex will give us the value of
p.
V(400,1000)
P(100,5000)
(xh)^{2}
= 4p(yk)
(x400)^{2}
= 4p(y1000)
(100400)^{2}
= 4p(50001000)
p
= 45/8 = 5.625
=>
(x400)^{2} = 4p(y1000)
(x400)^{2} = 22.5(y1000)
y
= (x –400)^{ 2 }+ 1000
22.5
This
is the equation for the inverse function. To find the equation for the curve of the argon ion laser, simply
interchange the x and y. The equation produced is:
y
= ±(22.5)
(x1000)
+ 400
Only
the lower half of the graph, the negative portion, represents the curve
for the argon ion laser. Therefore,
the equation is: y = (22.5) (x1000)
+ 400

In
5,000 hours, the Spectra Physics solid state laser executes 167% of the
work the argon ion laser executes in 5,000 hours.
In other words, the Spectra Physics solid state laser executes an
additional 67% of work than the argon ion laser.

In
these days of ever increasing electricity prices, we wanted to highlight
the low power consumption level of the Solid State laser verses the
older technology of the Argon laser.
