Last year, Autodesk announced its consumer Ember 3D printer at the MakerCon conference in California, along with an open-software 3D printing platform called 'Spark' that will connect digital information to 3D printers in a new way. The company invites the entire 3D printing community to collaborate, build and improve the platform, its associated Ember 3D printer and materials.
The Autodesk Ember 3D printer ships with 2 liters of their Standard Clear Prototyping resin. Autodesk calls it PR48, which stands for polar resin number 48.
Today, the company shared the formulation of the PR48 under the Creative Commons Attribution-ShareAlike license, the same license Arduino uses to share their design files, and encourage makers to remix and remake their own resin at home.
Eric J. Wilhelm, the founder of Instructables.com and heads Autodesk's hardware group said in the announcement:
"We're open sourcing our resin for a couple of reasons:
- We have an open approach, and encourage the use of 3rd-party materials in our printer. We include 3rd-party materials in the defaults for Ember's online model preparation and slicer, and are adding more as we optimize their settings for Ember: you can check them out at emberprinter.com. (You don't actually need an Ember to use the site.) This Instructable describes how to test new resins.
- Autodesk is thinking differently about 3D printing, and sharing under an license reflects our commitment.
- Open sourcing our resin formulation is only the first step in the journey of opening our 3D printer and our Spark 3D printing platform.
"We think PR48 is a pretty good resin: it properly adheres to the build head, photopolymerizes at a reasonable rate, clouds Ember's PDMS window significantly less than other resins, and generally works for most prints." Wilhelm added.
Autodesk Standard Clear Prototyping Resin for Ember (all percentages are wt/wt)
- Photoinitiator: 2,4,6-Trimethylbenzoyl-diphenyl-phosphineoxide (TPO) 0.40%
- UV blocker: 2,2'-(2,5-thiophenediyl)bis(5-tert-butylbenzoxazole) (OB+) 0.16 %
- Reactive diluent: Genomer 1122 19.89%
- Oligomer: Ebecryl 8210 39.78%, Sartomer SR 494 39.77%
However be aware that the material is for professional use only. Autodesk also reminds users that working with this formula is at your own risk. So before you undertake any work with the formula, review carefully the safety warning notifications and the Material Safety Data Sheet for PR48 here.

How good it is to see that one of the potential giants within 3D printers are taking an open source approach! This itself would have a great impact on my decision of whether to buy the Ember or not. :)

Nice!! I am really pro open source chemistry :).
