     Mr. Mike Naylon:

  I appreciate your prompt reply so much in advance.
  But I don't think 'Direct AIM',developed by 3D Systems,can meet
  some requirements as an injection mold, viewing from a little
  experience of mine.

  If you have some information,which I don't know in detail, about
 'Direct AIM', please let me know.

     Best regards.
