Grenoble, France – ESPRIT CAM, a computer-aided manufacturing software developed by DP Technology that supports a variety of CNC machines, has extended its existing partnership with France’s Technical Centre for Mechanical Industry (CETIM) to include additive manufacturing. CETIM was established in France in 1965 in order to improve companies’ competitiveness through mechanical engineering, transfer of innovations and advanced manufacturing solutions.
Additive manufacturing (AM) creates parts in 3D, breaking out limits and supplementing historical manufacturing processes. AM technology is made of several sub-technologies, as described in the AM Field Guide. ESPRIT supports both direct energy deposition (DED) and powder bed fusion (PBF) with products that have been tested and validated by industrial partners.
In 2020, teams from ESPRIT continued to develop products to enhance the support of additive technologies, according to the company. ESPRIT released a new feature which adds support to several new slice formats such as 3MF and Binary CLI, further improving interoperability between software and machines. Binder jetting uses a liquid binding agent to bind powder particles one layer at a time until the final product is complete, or “printed.”
Relying on an established collaboration with CETIM, ESPRIT teams validated the support of a third AM technology: binder jetting. By preparing data in ESPRIT Additive Suite products, CETIM was able to build a job made of six impeller parts with a binder jetting machine from Sweden’s Digital Metal.
“We used the ESPRIT Additive PBF product to slice the 3D model and produce a compatible file format that would be readable by Digital Metal’s machine,” says Clement Girard, ESPRIT’s additive product manager. “All data preparation was done using a version of ESPRIT Additive PBF that’s still in development.”
Although ESPRIT Additive support for binder jetting technology is not yet commercially available, this success demonstrates what’s possible when both teams collaborate closely, according to the company.
