5.18 Witness Part

In situations where the color and surface quality must be the best possible, ZPrint gives you the ability to

generate a “witness part”. A witness part is an additional thin shell of grey material that is created with a

small offset from the actual part. It is situated along the surfaces of the part that the printhead first

approaches as it is printing. Printing the witness part causes the printheads to fire just before they have to

begin printing the part. This “primes” them so the colors on the part are crisp and true.

5.18.1 Create A Witness Part

1. Select your part in ZPrint.

2. Select Edit > Make Witness Part.

3. The Witness Part dialog appears.

4. Enter the values for Clearance and Thickness.

NOTE: It is recommended that you use the default settings as they are configured for your printer pow-

der type.
