This thread was begun in an effort to document changes between the different resin formulations.
| Resin | Version | Announced | Changes / Comments |
|---|---|---|---|
| Clear | V1 | May 2013 | |
| Clear | V2 | Nov 2014 | Reduced yellowing; added support for 200μm. |
| Clear | V3 | April 2016 | Color may be slightly more grey / blue out of printer, but more stable over time. Discontinued shortly after launch due to manufacturing issues. |
| Clear | V4 | Late 2017 | Mixable with Clear V2 and yields identical results. (Note in Oct 2017 Preform 2.13 corrected profile for faster printing). |
| Grey | V1 | Aug 2013 | |
| Grey | V2 | Nov 2014 | May yield better results than V3 on Form 1/1+. |
| Grey | V3 | Jan 2017 | Matte finish, darker shade, better dimensional accuracy. Slightly more brittle. |
| Grey | V4 | Late 2017 | Supplier change; similar to V3 and mixable with it. |
| White | V1 | Dec 2013 | |
| White | V2 | Aug 2016 | More vibrant color. |
| White | V3 | June 2017 | Matte finish. |
| White | V4 | Late 2017 | Supplier change; similar to V3 and mixable with it. |
| Black | V1 | June 2014 | |
| Black | V2 | April 2016 | Minor reformulation related to supply chain. |
| Black | V3 | June 2017 | Matte finish, enhanced feature resolution. |
| Black | V4 | Late 2017 | Supplier change; similar to V3 and mixable with it. |
| Castable | V1 | Oct 2014 | |
| Castable | V2 | June 2016 | More opaque for better detail, optimized for 50μm. (Blog) |
| Flexible | V1 | Oct 2014 | (Blog) |
| Flexible | V2 | April 2016 | Color changed to black, improved tear strength and UTS, reduced viscosity. |
| Tough | V1 | June 2015 | |
| Tough | V2 | Apr 2016 | Formulation change due to new supplier. |
| Tough | V3 | Oct 2016 | Much stiffer and stronger. Smaller contact points. |
| Tough | V4 | Apr 2017 | More blue due to supplier change. Mixable with V3 and nearly the same mechanical properties. |
| Tough | V5 | Late 2017 | Supplier change; similar to V4 and mixable with it. |
| Durable | V1 | Oct 2016 | Originally yellow, but changed to frosted clear on release in Jan 2017. |
| Durable | V2 | Late 2017 | Supplier change; similar to V1 and mixable with it. |
| High Temp | V1 | Oct 2016 | |
| Dental SG | V1 | Apr 2016 | Class 1 biocompatible for surgical guides. |
| Dental LT Clear | V1 | Oct 2017 | Long-term Class IIa biocompatible for splints and retainers. |
| Dental Model | V1 | March 2017 | Exceptionally accurate, particularly at 25μm. |
| Dental Model | V2 | Nov 2017 | Supplier change; similar to V1 (and same accuracy). |
| Color Base | V1 | Dec 2017 | Comes with CMYKW pigments to produce matte, opaque parts. Base color is a different white than standard. |
| Grey Pro | V1 | Jan 2018 | Slightly improved tolerances and resistance to peel deformation vs Grey V4. |
| Rigid | V1 | Jan 2018 | Glass reinforced, requires Resin Tank LT. |
For the Standard resins:
- V1 → V2 reformulations were largely due to changes and optimizations in components supply chain.
- V2 → V3 applied matte coloring on Grey / Black / White, for aesthetics and better detail.
- V3 → V4 once again due to supply chain changes (which further encompassed Durable V2 and Tough V5).
