Mars 3 Pro - BlueCast XOne Settings

Recommended print and support settings for the combination of:

  • BlueCast XOne resin
  • Mars 3 Pro printer
  • 0.030mm layer height
    can be downloaded from the Jewelry committee drive.


1. 0.030mm layer thickness

Strongly recommend 0.030mm. All of the professional jewelers on the BlueCast site are using this layer thickness. Comparison printing confirms a huge improvement over 0.050mm. It takes longer to print but if you’re going to spend the time/effort/money to cast something you may as well start from the best wax master.

2. 35 - 45 degree tilt

BlueCast recommends that flat parts be printed at angles greater than 30 degrees tilted to the build plate; reduces shrinkage and distortion especially if you’re not going to cast within a day or two of printing. The XOne people stated that “at low angles the underside will form at a different density to the main body. Try above 30deg”. Experimentation confirms that. Some parts printed flat also had no details on top surface.

3. 5.5 sec exposure

5.5 second exposure was determined by running Cones of Calibration and confirmed by printing a known good, highly detailed part in the same batch to confirm that real parts perform the way the cones predict.

The advanced settings include a Tolerance Compensation setting that helps reduce detail bleed and increases the crispness of the details.

4. Beefy supports

BlueCast is a thin (non-viscous) resin and they strongly recommend using “beefy” supports. Light supports are discouraged. Support settings are a combination of things from the BlueCast support group and my own testing. YMMV.

Thank you for doing this!

This is the kind of information that would be great to have on Source. It would be much easier to find than trying to find that elusive “Talk post that someone made a year or so ago”. I’m willing to help make that happen if @Team_Jewelry would like.

I’m not official, but if you can add that note to Source, I say go ahead.

I realize that it’s on the Committee Drive, but if a person doesn’t realize that they should go look on the Committee Drive, a note in Source will help them out.

Thank you @John_Marlow for taking the time to help us get that machine dialed in!
@CaryF300 please do. Thank you for volunteering to help us with that, much appreciated!

This information is on The Source now. I created a page called Mars 3 Pro Settings Recommendations under the Jewelry Studio page. As other resins are documented they can be added to the page. Glad to be a help.


Thanks very much for doing this. I added the link to the tools page.
