Last week, Magnum Venus Products (MVP), in partnership with the Department of Energy’s Oak Ridge National Laboratory (ORNL), installed the first commercially available medium/large-scale thermoset 3-D printer at the DOE’s Manufacturing Demonstration Facility in Knoxville, Tenn. ORNL contributed to this project through a DOE Office of Technology Transitions Technology Commercialization Fund project managed by the Advanced Manufacturing Office in DOE’s Office of Energy Efficiency and Renewable Energy.

According to MVP, the 3-D printer was developed in response to growth in 3-D printing, a market demand for hyper-customization and the need for advanced manufacturing automation.

As MVP explains, while 3-D printers have been around for years, the additive manufacturing industry had needed a cost-effective solution that could print structures and molds. MVP engaged with ORNL to create a 3-D printer capable of printing large-scale thermoset materials.

“Thanks to this innovation, research and development managers will be able to prototype faster and bring products to market faster,” said Bob Vanderhoff, President and CEO Magnum Venus Products. “Procurement departments will also enjoy shortened lead time on crucial molds – allowing for rapid deployment. This was made possible through ORNL slicing software that allows the integration of multivariate print process parameters.”

The MVP machine features, what the company is calling a “state-of-the-art” gantry system tailored to each application.

“The ability to print thermosets on a large-scale opens new possibilities with respect to the performance and integrity of printed structures,” said Vlastimil Kunc, ORNL lead for polymer materials development.

According to MVP, the roll-in/roll-out bed configuration of the printer dramatically increases the productivity of additive manufacturing. The configuration allows the printer to operate while pre- and post-processing operations are performed on an additional print bed outside of the machine. The benefits include rapid prototyping molds, rapid mold building, and creativity with an all-new material for cutting-edge companies.

Specifications include:

  • Multi-axis print head and coordinated control of other print process parameters
  • Build volume: 16’ x 8’ x 42’’
  • Prints up to 50” per second (depending on material used)
  • Deposition rate ≥ 10 lbs./hr.
  • Resolution of ≤ 6mm and larger resolution is possible
  • Build platform with 1,000 lb. capacity
  • Repeatability = ±0.005”
  • Large footprint easily scaled to multiple sizes
