Hi Ricardo,
Yes! Our SL resins are currently in use as end products. Also, look at
the new materials that have come out in the past 4 years, including the
one you mentioned. What a difference! The industry went from several
General Purpose brittle resins to a wide range of SL materials with
unique and different mechanical properties. At this years SLA/SLS
User's conference, more SL resins were introduced than ever before.
Just wait and see what is developed in the next 4 years. But the SLS
technology is also advancing in accuracy and materials. Nothing stays
the same!

Dear all,
Considering the new materials developed for the SLA process, like DSM
Somos NanoForm 15120, could SLA compete with the SLS process, regarding
direct manufacturing of plastic parts?
It is well-known that SLA is the best rapid prototyping process
regarding its accuracy. But, the main limitation was always the
material mechanical properties and dimensional stability.
So, could someday, SLA be used to manufacture end parts?
