For my sake and interest, would you please elaborate on the section in item 4 to address the following questions:

   * What are the dimensions of the features that "dissolved in the support layer" ?
   * What equipment was used for support remmoval ?
   * Can you provide the STL file of the part which was inadequately formed as well as the part that "Sanders could not
     build" ?
     I would also like to see the part that is built "40 to 50 times faster"

Rising to the challenge,

ps. Please be certain to respond to my email address as well as the rp-ml - for some reason I don't see everything that
is posted on the rp-ml.
