Researchers at Oak Ridge National Laboratory (ORNL) have introduced Slicer 2, an advanced slicing application designed for large-format 3D printing. Slicer 2 accelerates and simplifies the digital conversion process for large, precise 3D parts, facilitating the production of sizable objects like aerospace components and vehicles from metallic and composite materials.

Slicing software converts CAD models into two-dimensional layers, calculating print parameters for each slice. This information guides the 3D printer’s movements to create accurate 3D objects. Slicer 2 enhances this process by integrating directly with various 3D printers and sensors, improving print accuracy through real-time feedback.

Slicer 2 offers over 500 settings to control internal structure, shape, temperature, and more. It interfaces with simulation software to manage complex heat and stress relationships during printing. The software supports a variety of additive manufacturing systems, including thermoplastics, concrete, and directed-energy deposition.

“This connectivity translates into improved machine commands that increase reliability and repeatability of the additive manufacturing process,” said Alex Roschli, an ORNL researcher.

“The result of this software is that additive manufacturers can produce large factory parts with fewer machines and less cost than traditional machining methods.”

This software integration results in improved machine commands, enhancing the reliability and repeatability of the additive manufacturing process. Consequently, manufacturers can produce large parts more efficiently and cost-effectively than traditional methods.

Available on GitHub, Slicer 2 is used by over 50 manufacturers, industrial users, and universities, supporting the transformation of U.S. manufacturing through ORNL’s Manufacturing Demonstration Facility.
