Dimensional Calibration Of A Printed Model In X And Y Axes - 3DGence INDUSTRY F340 Maintenance Manual

4. DIMENSIONAL CALIBRATION OF A PRINTED MODEL IN X AND Y AXES

Recommended frequency:
The 3DGence INDUSTRY F340 printer is one of the few to feature a unique system of precise dimensional
adjustment of a printed model. When printing with the use of materials with different thermal shrinkages, it may
be necessary to make dimensional adjustments. For most printers, such adjustment can be very inconvenient or
even impossible. Thanks to an innovative system, 3DGence INDUSTRY F340 allows you to easily and quickly make
precise dimensional adjustments. The system using a single calibration print and some simple measurements
allows you to achieve the accuracy of 0.02 mm.
NOTE: Each filament material has unique thermal shrinkage properties. For the most accurate results, such
calibration should be carried out for the material which is to be used for printing.
Procedure for dimensional calibration of a printed model in X and Y axes:
1. Download the .stl model of the calibration solid Dimmension_Calibration.stl (Fig.2). The .stl model can be
downloaded from www.3dgence/support in the tab Your files (the tab is available after you sign up and
register your device).

2. After downloading the calibration model, prepare the .gcode file in the 3DGence Slicer software for the
material you will use for printing.
3. Load filaments by selecting Material Status → Load Filament from the printer menu under the appropriate
TOOL 0 or TOOL 1 extruder and follow the instructions on the printer display.
4. Start printing the calibration model.
5. Wait until the cooling process is complete after you finish printing. Remove the model carefully and wait
approx. 5 minutes for the temperature to stabilise.
6. Place the printed item on a flat surface and measure the dimensions along the X and Y axes. The axes are
marked on the model.
Different tools can be used to measure the accuracy, but their accuracy must not be lower than 0.05 mm:
•
a calliper,
•
a micrometer,
•
a coordinate-measuring machine,
•
optical tools.
The measuring point should be above the step located in the model. The step will make it easier to measure
at the same height on both sides of the model (Fig. 3),
Measure the X and Y axes 5 times each and take down the measurements. Discard the highest and lowest
measurement in each group. Calculate the average of other dimensions for each axis (Fig. 4).
