Elegoo Mars UV Printer and Castable Resin Limitations

Knowing the limitations of your Elegoo mars printer, while printing castable resin is important to know when you are using your computer to design custom one of a kind jewelry.  Castable resins, especially wax resins will print completely different than those that most of you are used to.  You should know what can be printed with the resin you are using.

In the example to the right, note that the bridge that spans the bezel, should never be less then .55 mm.  The purpose is to create a bridge that will both print, as well as once cast, be structurally solid.

The outside perimeter should be as large as the bridge or larger.

If you’ve watched the video, you will see why the bridge needs to be so thick, but half of a mm is actually quite small!

 

When designing ring shanks, (the ring part itself, not the top), the width and thickness should not be any smaller then 1.25 mm.  The bottom of the ring is usually the smallest and thinest part, so keep that in mind.

The balance of the ring shank should tapper up in size as the shank moves up from its bottom to the top.

whenever I design a ring, I never cast a ring that has a minimum ring thickness less then 1.7 mm.  This allows me to anticipate wear over time, and gives the ring ample strength.

Hey, if you haven’t gotten your Elegoo Mars Printer, you better get one Now!

This is a great little printer that is a workhorse, right out of the Box!

Designing heads and prongs is important.  Small stones don’t need prongs smaller then .7 mm.

However, if you are creating a setting that is going to have a large stone set into it, then make your prongs substantial enough.

A 6.5 mm Round Diamond is the equivalent to 1 ct.  The prongs should be at least 2 mm, and you can adjust from there.

Larger stones should have thicker heads or prongs.  Try and keep your design dimensionally correct as well as eye appealing.

OK, so I know you can not tell by looking at this, but this was a quick design I did for a ring topper.  

It measures in at about 18mm in circumference  and the perimeter is about 1.25 mm thick.

Because of the resin I used to print the final product, I had to make the inter mesh structure about .75 mm in diameter.  Any smaller then this would not have printed well, and in casting, may have given me poor support.

 

Dimensions are Important!

So, as I’ve tried to cover some of these issues in regards to minimum thicknesses, I hope you understood what it is I’m trying to convey.

If you are using a different resin, then at least print the stress figure that I offer above for download.

You should be able to import that right into your slicer and send it to your printer.  This will help you to see the dimensional errors you may get when printing on the Elegoo Mars or Anycubic Photon.  

Both of these printers are fantastic, so don’t miss out if you haven’t purchased one.  Don’t be afraid to start designing great jewelry, and lets make the world Print Better Together.

Thanks!d
