Accuracy Wizard

To help ensure exact scaling of your printed parts, you may use the Accuracy Wizard in 3D Sprint.

NOTE: You will need calipers or a micrometer for this procedure to measure printed parts.

 

  1. You must have geometry loaded to begin the process. Either load an STL file or click Generate Geometry. This will place a cube in the build area by default. Click Set.

  1. Click the Build Style button.

  1. In the Build Style window, click the Scale & Offset Wizard button.

  1. In the Wizard, you will see the following buttons, depending on whether 3D Sprint is connected to the printer:
    1. If you are using the Standard Build Style, click Add Reference Build to Queue. Doing this will automatically create a .pxl file with four standard parts and submit it to the print queue. These parts will be printed using the Standard Build Style and other background factors.
    2. If you are using a custom Build Style, click Make Custom Reference Build File. Then do the following:
      1. Open the Smart Supports dialog window and click Create Supports.
      2. In the Build Style window, manually set the following fields to 0: X Offset and Y Offset.
      3. In the Build Style window, manually set the following fields to 100%: Scaling Factor X and Scaling Factor Y.
      4. Print the part.
    3. If 3D Sprint is not connected to the printer over your network, the top button will instead read Save Reference Build File. This will output a .pxl file that you can save to your computer or USB device, to load on the printer later.

  1. Run the printing process, as outlined in the section Begin Your Print Job. This will print four parts that look like the models at the right. They should be roughly (clockwise from top-left) 13x10mm, 18x15mm, 23x20mm, 28x25mm. The dimensions and x/y axes will be printed on the part. Post-process the parts as in the section Post Processing.

NOTE: Some printer configurations will print five models. Be sure to include this model's measurements in future Steps in the wizard.

  1. Open 3D Sprint again and click the Scale & Offset Wizard button to open it. This time, instead of adding a reference build file to the queue, you will click the Next button.

  1. Measure the parts printed in Step 6 with calipers or a micrometer in the X and Y directions. You will measure the parts four times each in X and Y and input your measurements in the fields in the wizard that correspond to the part you are measuring. You will notice that every time you enter a value, the number in the "Average" column updates to show you the average of your measurements.
  2. Repeat this process for each of the models and click Next when you are finished.

  1. You will then see the results screen, which will show you how much the printer will now offset builds with this build style. It also shows you the scaling corrections as a percent. Click the Apply button to add this scaling to your current build style.

  1. 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.
  2. Remember that the Build Style is tied to the print material you are using. If you use a different print material on another print job, you will need to run this wizard again for that material. 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 it is the style with scale factors applied by looking at the Scaling Factor fields in the Build Style window.
  2. Click File > Save to save your work.
