You got me there, perhaps mass is not the best metric. I threw it out
'cause I had the (well rounded) numbers on top of my head and the density
difference between epoxies and Duraform PA is insignificant. In self
defense, however, when building a sla quick cast part, the opposite
situation vs. GF arises.... i.e. build time is driven more by mass than
volume. The density of a QC part is highly variable depending on build
parameters, drain time, and surface to volume ratio.... but we diverge.

Interesting method of quantifying output.
Mass?
So why don't you switch to Glass Filled material for SLS.
Then you can increase your output by . . let's see . .how much more dense is
it . . . 40%
1.4KG per day.
Seriously though, I would love to hear more people's input on the FDM's
capabilities and speed. (or lack there of)

Subject: Stratasys Super Slow?
Judging from the banter going round on Stratasys' quarterly results, the
main complaint about their product seems to be speed. Just how slow is the
FDM process? As comparison, I usually figure my old sla500's can kick out
roughly 2 kg per day, an sla250 maybe a half kg per day, and an sls2000
maybe 1 kg per day. Any other gripes regarding FDM? .... reliability? ....
maintenance? ....cost? What about the positive aspects? Thanks for
your input!
