­­Stratasys Origin One Exploratory Open Materials

Article by Hunter Bernstein on Jul 28, 2022

On April 28, 2021, Stratasys released the Origin One 3D printer as a production-ready solution for high yields of functional end-use parts rivaling injection molding quality. This machine uses Programmable Photo Polymerization (P3) technology, an evolution of DLP 3D printing, to achieve high accuracy, fast printing speeds, and reliability. 

Certified high-performance printing materials developed by chemical manufacturers like Henkel, BASF, and Covestro are the premier choice for the Origin One. The material offerings certified by Stratasys provide users with an end-to-end workflow for processing and print settings for these photopolymers without the need to adjust or tune settings. 

Even with the continuous growth of certified materials for the Origin One, what happens if the material properties your application demands  aren’t  provided by the current offerings? Fortunately, Stratasys offers an Open Material License (OML) for the Origin One, allowing customers to explore, develop and optimize advanced photopolymers meeting their specific needs. 

What is an Open Material License (OML)? 

The Open Material License (OML) is an advanced set of tools offering users control over critical printing parameters and settings. The OML: 

  • Enables users to print with non-certified materials (third-party photopolymers)
  • Provides the ability to formulate new printable chemistries
  • Includes a set of advanced tools to optimize prints for speed, throughput, quality, strength, and experimentation.

Material development requires a significant number of tests – a process that can take several months or even years. Without control over the printing process, it can be difficult to distinguish printing failures due to improper print settings or the chemical formulation. 

The Origin One OML provides complete control over all critical printing parameters through highly configurable settings. This results in accelerated material development and formulations, making the Stratasys Origin One preferred by current chemical manufacturers and OEM’s. Key process parameters of the OML, which can be modified on a per-layer basis, include: 

  • Layer thickness
  • Chamber temperature
  • Resin temperature
  • UV exposure
  • Movement speed and position
  • Transition timing

The Stratasys Origin One, combined with the OML, is a powerful tool for developing photopolymers without limitations set by high heat, high viscosities, and reactive chemistries. It is ideal for users involved in material science, chemical formulations, process optimizations, educational & research institutions, and/or third-party material exploration.

Exploring Third-Party Material Offerings

On May 10, 2022, Stratasys officially announced the exploration of new material partners expanding possible use cases for customers with the Origin One and an OML. Stratasys identified eight new materials that are currently available and printable on Origin One 3D printers for those wishing to explore exotic or novel applications. 

Although OML users can develop or print any available 385 nm DLP material, narrowing down the selection to a list of recommended materials can expedite the process. If the chemical manufacturer has already developed a print profile for a material, it is possible for this to be shared amongst additional OML users. 

Photopolymers announced by Stratasys for the Exploratory Materials include:

  • Covestro PerFORM HW
  • BASF Forward AM RG1100
  • PolySpectra COR Alpha
  • Evonik RG3101 L
  • Liqcreate Strong-X
  • Mechnano Formula1
  • Tethon 3D Komitsudo Ceramic 
  • Arkema N3D-CAST011

Mechnano Formula1 is a black, rigid, static-dissipative photopolymer resin that was created using proprietary discrete Carbon Nanotubes called MechT. Formula1 uses a urethane di-methacrylate base that includes a stable dispersion of discrete functionalized CNTs to achieve consistent static dissipative properties. MechT does not settle in Formula1 resin, resulting in consistent ESD-capable parts.

We welcome Mechnano to our growing materials ecosystem as we work together to create unlimited opportunities for additive manufacturing across the product value chain,” said Ronen Lebi, Vice President, Head of Production (P3) at Stratasys. “The goal of our open, exploratory materials program is to rapidly expand the availability of novel materials, because that means compelling new additive manufacturing applications for our customers. We’re excited to see the innovation that this program will unleash.”

The discrete nature of MechT produces parts that leave no carbon trails with improved key mechanical properties such as tensile strength, modulus, and impact resistance when compared to Mechnano’s Base Formulation. 

Notable properties of this photopolymer are:

  • Isotropic surface and volume resistance: 10⁷ Ω
