Sorry - this is not the case. Resin disposal and post curing time have
absolutely no impact on any time and cost difference. SLS has different
post finishing issues that pretty much equal out the time.

As for the resin disposal, it is only an issue in the liquid form. As a
liquid, the same disposal issues for SLA resin apply as to simple
degreasers, etc. that are redily found in most any RP shop regardless of
technology used.

The real answer was stated earlier by Roger and others. Simply a function of
'opportunity cost.'
