No. 1
Depends on who's doin' the work. You could have terrible powder and do no
post processing and end up with a hunk of junk. Or, you could use good
powder and do some post processing and be very close to SLA.
No. 2
Depends on the kind of part. Not all people need great surface finish.
But, if you want a marketing model for a photo shoot, I would have to say
that surface finish IS the be all and end all.

Subject: Surface finish - Comparisons and Importance

Dear All

No.1
What is the surface finish like on parts made from DuraForm(TM) Polyamide
and DuraForm GF - compared with other technologies/materials?

No.2
Does any body else agree that surface quality is not the be all and end all?
ie.......... how good does it need to be?

Best Regards

Mark
