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.
