China3D printingNet November 26th, ESPRIT is the flagship software product of computer-aided manufacturing (CAM) software developer DP Technology. It has established a partnership with Almacam (a developer of CAD/CAM software for sheet metal processing, cutting and robotics). To provide a complete programming product for direct energy deposition (DED) of robotic additives.
These companies will combine their areas of expertise in the areas of subtraction and addition, as well as advanced tool path planning for robot trajectory calculations, and provide customers with end-to-end plans for robot addition DED.

Additive Direct Energy Deposition TechnologyDED
Additive DED involves the use of multiple metals3D printingTechnology (for example, Arc Arc Additive Manufacturing (WAAM)), which creates parts by melting and fusing materials during deposition. When used for robotic additive DED, WAAM can not only significantly reduce costs and shorten lead times, but also increase material efficiency and improve component performance.
The cost of robotic DED machines is much lower than that of machine-based DED machines, which can cost millions of dollars. The company can transform its existing programmable industrial robots for value-added DED applications by determining the tool path of the DED head and robotic arm. This is where the software provided by ESPRIT and Alma comes into play.

ESPRIT’s partnership with Alma
The technical partnership between ESPRIT and Alma will produce a complete workflow software that provides users with dedicated additional tool path planning and programming. The software will also provide robot programming, simulation and verification, as well as collision detection and code generation functions.
Through this cooperation, Alma can use 3 times, 4 times and 5 times the cumulative DED cycle of ESPRIT, while enabling Esprit to support industrial robot brands such as Yaskawa, ABB, Fanuc and Kuka. These companies have already collaborated with several customers and research institutions to verify that the software can be used in a variety of applications and have tested it with various robot brands.
The workflow begins with the additional operating suite available in ESPRIT CAM, where ESPRIT’s automatic tool tilt DED cycle is used to program parts to generate tool path trajectory calculations. Then run a cycle simulation on a sample 5-axis DED machine on ESPRIT to understand the overall deposition and verify the tool path.
According to China3D printingNet understands that once a suitable tool path is created, it can be applied to the robotic cell through Almacam’s technology. Almacam reads ESPRIT files and uses its own kinematics software to simulate and program the robot’s movement. By combining ESPRIT’s tool path and Almacam’s robot programming, the workflow finally reached its peak in the manufacturing process.
ESPRIT and3D printing
Earlier this year, DP Technology announced several software updates to the ESPRIT CAM system. The first update includes new features such as a balanced turning cycle and enhancements to its existing detection and additional DED functions.
Soon after, DP Technology released new elements of ESPRIT software designed specifically for powder bed fusion (PBF). This program is an additional application to the computer-aided design (CAD) program SolidWorks, with the purpose of increasing the number of additive manufacturing processes it supports.
Recently, DP Technology was acquired by Hexagon AB Technology Alliance, and the transaction included the ESPRIT CAM system into Hexagon’s manufacturing intelligence department. It is hoped that this global platform can enhance ESPRIT’s influence in the market.
