PML is an inspection/engineering service bureau in Los Angeles.
We have been using Helisys LOM to produce sand and investment
cast tooling for about a year now.  We have also been inspecting
(dimensionally) both LOM and STL models for several years.  This
gives us an understanding of the realistic dimensional capabilities
of these systems.  Give us a call if you want to talk or 
email us.
