Scale and Offset Wizard

For each VisiJet M2 material, the "General" build styles in 3D Sprint are designed to give you accurate prints right out of the box. Please use the "General" build style first and foremost to achieve part accuracy. However, if after measuring your parts you find that you have issues achieving accuracy, you may use the "Scale and Offset Wizard" in 3D Sprint to troubleshoot such issues.

Each ProJet MJP 2500 printer will vary slightly in accuracy. If you have multiple printers, you may need to set the accuracy for each one separately. To do this, click the "Printer" icon in the upper left corner, connect to a specific printer, and run the steps in this section for each printer. Additionally, you will need to run the wizard for each Material,Print Mode, and Build Style combination you use.

  1. Click the "Load Reference" button to load the accuracy models that will be printed. screenshot 1.png
  2. Print the reference build on your ProJet MJP 2500, then post process the parts.
  3. Click the "Printer Tools" button, then select the "Printer Settings" button. screenshot 2.png
  4. In the "Printer Settings" window, select the build style you used to print the reference build, then select the "Scale and Offset Wizard" button. screenshot3.png
  5. Measure each part using calipers, micrometer, or height gauge, then input the measurement values to corresponding boxes in the "Scale and Offset Wizard". Each measurement is repeated 4 times. Be sure to input the values for parts labeled with X, Y, and Z before selecting the "Next" button.

NOTE: Before measuring, wipe each end of the measurement part with a paper towel to remove excess wax remaining after post processing. Also be sure to wipe clean your measurement device before measuring.

  1. Once all measurements are complete, select the "Next" button.

  2. You can now see the calibrated slope and offset values. If you calculate a corrected slope and offset on your own, be aware that the offset range will be limited to [ 0, -0.002 ] inches. 

  3. Select "Apply", and 3D Sprint will allow you to change the name of your new "Build Style". By default, the syntax includes build material, print mode, and the date. You may add to the printer name as well if you have more than one ProJet MJP 2500 printer.

  1. Be sure to press the "Set" button instead of closing the printer settings window. Pressing "Set" will not only set this new build style for your current 3D Sprint build, it will also save the build style for future use.
  2. You will now be able to select this style from the "Build Style" menu going forward, allowing you to build with these scale factors at any time.
  3. Remember that the Build Style is tied to the build material and print mode you are using. If you use a different print mode, build material, or printer, you will need to run this wizard again for that combination. The software will automatically create "name the new build style", but you can click the "Rename" button to rename it.

  1. When you select this build style in the future, you can verify that this is the style with scale factors applied by looking at the scale and offset fields in the "Printer Settings" window.
  2. Print your next build using this new build style. The accuracy of your parts should now be slightly closer to perfection.
