What are the strongest 3D-printing resins available?

During the development of Liqcreate Strong-X resin, we studied all available high strength resins to find out what was missing, so we could develop it. In this article we want to share the knowledge we gained during this research. All data is obtained from the official manufacturers datasheet and the source is copied below.

There are a lot of resins available and for users often difficult to identify if a resin is useful for their project. For instance there are dozens of “ABS-like” resins available, but if you take a good look at their properties, some of the properties like elongation or strength match real ABS plastic. The most important property, the impact strength is often just 10% of the impact strength of ABS.

What are the strongest 3D-printing resins?

We searched trough the internet and found some strong resins. All resins without a technical data sheet (TDS) were not taken into account. This brought us to the following top 5 strongest resins for 3D-printing anno March 2019:

  • 3D-systems Accura Ceramax 137-145 MPa[1]
  • DSM Somos PerFORM 120-146 MPa[2]
  • Liqcreate Strong-X 135 MPa[3]
  • Carbon3D CE221 131 MPa[4]
  • Formlabs Grey Pro 121 MPa[5]

Besides a high strength, all resins in the top 5, except the Formlabs Grey Pro resin claim to have an elevated temperature resistance and most can be used as injection molding inserts or as a complete mold for low volume injection molding.

Compatibility of resins

If we take a closer look at the resins in this list we noticed that there are only 2 resins which  can be used on open-source 3D-printers, These are DSM Somos PerFORM and Liqcreate Strong-X. Somos PerFORM is compatible with 365nm 3D-printers. Although there are no compatible 3D-printers listed,  we prosume it is compatible with big laser based SLA machines like UnionTEC, as this technology is famous for using 365nm lasers. While Liqcreate Strong-X is compatible with open-source 385-405 nm SLA, DLP and LCD 3D-printers, like:

  • Sprintray Moonray S & D
  • Formlabs Form 2
  • Formlabs Form1+
  • Miicraft 125
  • Cubicon Lux HD
  • Anycubic Photon
  • Wanhao D7
  • Phrozen shuffle.
