In May 2014, Autodesk acquired the UK’s Within Technologies for $88 million. The acquisition escaped the attention of the media because Autodesk did not announce it. We became aware of the transaction through a conversation with Jeff Kowalski, Autodesk’s chief technology officer. He said that it is not a secret, and the company will probably announce something when it has more detail to share.

Within Technologies is a London-based software company that developed the Enhance software. Enhance is used to reduce part weight and optimize part design by converting a solid part into skins and internal lattice structures. The software allows users to specify loading requirements, and then it automatically optimizes the topology and unit size of the lattice members. It is also capable of varying the size and density of the lattice and skins.

Two weeks before acquiring Within, Autodesk acquired the Nastran solver from NEi Software. Nastran is a proven finite element analysis product for analyzing linear and nonlinear stress, dynamics, and heat transfer characteristics. Autodesk has since added two new products—Nastran and Nastran In-CAD—to its simulation software portfolio.

These developments are a positive sign for the additive manufacturing industry. When and if Autodesk integrates the capabilities of Within Enhance into Inventor, Fusion 360, or another software product, AM designers will have new, powerful tools for designing and analyzing models created for additive processes. Currently, good design tools for AM are lacking, so we believe that these powerful capabilities will help accelerate the adoption of additive manufacturing.
