The 3MF Consortium (3MF) ratified and released its Beam Lattice Specification Extension to its 3MF Core Specification. The 3MF Beam Lattice extension is a new method for storing and transferring lattice-type geometry information. By providing support for beam lattices, 3MF solves an interoperability issue for the additive manufacturing industry and provides a solution to a problem that is not easily addressed in other file formats. The benefits of using 3MF’s Beam Lattice Extension in additive manufacturing include improved design flexibility, lower material costs and reduced production time.

Designers and engineers can use the extension to take full advantage of the additive manufacturing process and design the interior of parts creating designs that were not possible to produce only a few years ago. As the extension inherits all the features from the 3MF Core Specification, it retains build information, colors, materials and technology specific characteristics like support structures – all in one compact and well-structured file. The 3MF Beam Lattice Extension is available to download at https://3mf.io/specification/.

“The 3MF Beam Lattice Extension simplifies creation of lattice structures for 3D printing in additive manufacturing environments,” said Alexander Oster, chairman, 3MF Technical Working Group and director, Additive Manufacturing, Autodesk. “The central idea of this extension is to enrich the geometry notion of 3MF with beam lattice elements that can represent small-scale lattices as well as larger truss structures – both of which can be inefficient to handle with a mesh representation, especially in cases where the element count grows into large numbers.”

This is the fourth specification extension released by 3MF furthering its goal of providing a universal specification that serves as the backbone of the additive manufacturing ecosystem, and allows companies to focus on innovation, rather than on basic interoperability issues. The consortium provides open source code free of charge to keep the barrier of adoption to a minimum.

Companies that have adopted the 3MF Core Specification include: 3D Systems, Autodesk, Dassault Systèmes, HP, Materialise, Microsoft, nTopology, PTC, Siemens and Ultimaker. For a complete list of adoptions and partners: https://3mf.io/adoption/
