SLS Technology

Hello RP Users,

I have a few questions concerning the SLS machine:

1. Can anyone tell me how to calculate the beam diameter or laser spot size
of a CO2 laser as it sinters the powder at 3W or 4W? Does anyone know the
maximum intensity of the CO2 laser?

2. How can you find the average number of scan vectors per slice for any
*.stl file?

3. How can you determine the average scan vector length per slice? Is this
value based on the orientation in the X-Y plane?

Any help will be appreciated.

Thank you,
