-- [ From: Al Hastbacka * EMC.Ver #2.10P ] --
In an attempt to quantify the accuracy that is required for an
futuristic rapid prototyping system, I have polled several
different users from several application areas and have found the
following:
Name Application Accuracy
of Tool Pattern
User A Plastic Injection Molding Tools +/- 0.0007” to 0.0024”
User B Sand Casting +/-
0.003”
User C Castings +/-
0.005”
User D Master Patterns +/-
0.001”
It would appear from the above that an overall accuracy specification
of +/- 0.001” would meet essentially all of the requirements stated in
the survey.
I would like to know if the results listed above are in agreement with
what you believe an advanced rapid prototyping system should meet.

Al Hastbacka
