Differing SL Resin Properties

Andy:

The same SL resin in different machines will behave differently, even with
the same build styles. The SLA3500, 5000 and 7000 have different Solid
State lasers; same wavelength, but different pulse rates. This results in
different properties for the same resin.

So, the same resin in different machines results in different material
performances. Different green strength, different elongation after cure,
different impact resistance among others are the properties that will
change.

It's all a vast right wing conspiracy, or was that anther subject?

Why different properties? What different properties? Don't they all use the
same laser, same scanning algorithms? Except of course the 7000 in varible
spot size mode. I thought Ciba had discontinued Stereolithography resin
development. Or was that just for the 500?
