d. Within the Options panel, enter shrink compensations values for X or Y. Z compensation is rarely necessary (see table above for the values).*

2. Identify the exact X and Y dimensions of the part using a CAD program.
Most CAD programs and simple stl file viewers will provide a way to view a part with its dimensions.
a.
Make note of the actual X and Y dimensions as XCAD and YCAD.
b.
3. Build and clean the part and take measurements of the finished part.
It is recommended to measure along the critical dimensions of the geometry, take measurements in multiple areas and take an average of
a.
the values.
Measurements can be made using calipers or more advanced metrology methods.
b.
Make note of the X and Y dimensions of the printed part and mark them as XPART and YPART
c.
NOTE: If the measurement of the finished part is different from the measurements of the CAD model, fine tune the accuracy using
scaling factors.
4. Determine "Scaling Factor" to use for the next build
Use the following formula calculate the scaling percentage to be used on the "fine tuning" build:
a.
X Scaling Factor = (XCAD - XPART)/ XCAD * 100 (answer will be as a percentage)
Y Scaling Factor = (YCAD - YPART)/ YCAD * 100 (answer will be as a percentage)
EXAMPLE:
X measurement of CAD model = 3.000"
Y measurement of CAD model = 5.000"
X measurement of printed part = 2.998"
Y measurement of printed part = 4.989"
X Scaling Factor = (3.000 – 2.998)/3.000 *100 = 0.067%
Y Scaling Factor = (5.000 – 4.989)/5.000 * 100 = 0.22%
5. Enter "Scaling Factor" for adjustment build
