Accuracy Wizard

For each NextDent material, the Standard print mode in 3D Sprint is designed to give you accurate prints right out of the box. Please use the Standard print mode 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 Accuracy Wizard in 3D Sprint to troubleshoot such issues.

Each NextDent 5100 printer will vary slightly in accuracy. If you have multiple printers, you will need to set the accuracy for each one separately. To do this, click the Printer icon in the upper left, select each printer one-by-one, and run the steps in this section for each. Additionally, you will need to run the wizard for each Material/Build Style combination you use.

NOTE: Best Practices for using calipers on printed parts is demonstrated here (advance video to 2:38).

 

  1. Click the Load Reference button to load the accuracy models that will be printed.

  1. Click the Build Style button.

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

  1. In the Wizard, click Save Reference Build File. Name the file and save it in the desired location. The file will be output as a .pxl file that already has supporting architecture and the correct print orientation.

  1. If you are connected to the printer, click ADD REFERENCE BUILD TO QUEUE. The file that you created will show on the touch screen in the printer's queue

  1. Run the printing process, as outlined in the section Start Printing. 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 saving a reference build file, 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 (Refer to this video, at timestamp 2:38, for proper caliper usage). 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 new build style (see Step 12).

  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.

  1. At any time, you can verify that your accuracy values are still valid by running the verification .pxl file again. Go to Reference Builds > Load Reference Build File. This will automatically place the reference build parts onto the platform with proper supports and orientation.
  2. Click the Add to Queue button to send the .pxl file to the printer.
  3. Run the printing process, as outlined in the section Start Printing. This will print the four parts from Step 15. The dimensions and x/y axes will be printed on the part. Post-process the parts as in the section Post Processing.
  4. Use your calipers or micrometer to measure the parts. If they are not accurate, run Steps 8-10 once more.
