The German company EOS (Electro Optical Systems) has launched EOSPRINT 2.0, the latest version of its additive manufacturing (AM) CAM software for industrial 3D printing.
EOSPRINT 2.0 offers a number of developments over its predecessor EOSPRINT 1.0, including: a workflow-oriented graphical user interface (GUI); new plane segmentation capabilities; an open ParameterEditor module; and new exposure patterns1.
The software currently supports only the EOS M 290 and EOS M 400 metal AM systems. However, it will eventually be made available for all of EOS’s metal AM systems and future polymer AM systems.
EOSPRINT 2.0 features a workflow-oriented GUI that reflects the AM CAM process. This means that the software architecture is built around the workflow of data preparation for industrial AM.
The GUI’s click-based functions guide users through all required steps in the preparation of their files for printing. All of the tools and features behave according to the context of each of the steps, making the software intuitive and therefore easy to use.
New plane segmentation capabilities
The software incorporates new plane segmentation capabilities that allow for the realization of different layer thicknesses in a single part. These enable the user to split their part along a plane and then shift it at z-level to define segments depending on different exposure requirements.
This means that if a segment needs to be high quality or built at speed, it can be assigned machine parameters that are optimized for quality or build speed, respectively. Companies are thus said to be able to achieve an optimal mix of part quality and build speed, resulting in improved overall levels of productivity.
Open ParameterEditor module
EOSPRINT 2.0 introduces an open ParameterEditor module for experienced material and process developers. It offers an open tool set that contains exposure patterns and parameters for greater application-specific parameter optimization.
The ParameterEditor permits users to change not only all relevant standard parameters, such as laser power and scan speed, but also certain expert parameters. For example, they can customize the order and number of exposure types as well as vary the start and rotating angle for strip patterns.
Furthermore, the module enables users to create their own materials and parameter sets for increased competitiveness in terms of quality, productivity and costs. This function is largely determined by the software’s new exposure patterns.
New exposure patterns
The software adds three new exposure patterns to the existing exposure patterns carried over from EOSPRINT 1.0. One of the patterns allows for the building of previously unbuildable parts through the avoidance of support structures in areas where they cannot be removed. Two of the patterns can reduce build time by 20% compared with those from EOSPRINT 1.0.
Gerd Denninger, software product manager, EOS, said: ‘We advanced EOSPRINT in accordance with market needs, particularly in the fields of ease of use, higher part quality and increased productivity. EOSPRINT 2.0 makes the initial steps of the actual AM build process easier, and the comprehensive AM CAM environment enables engineers to reach higher quality and lower cost than ever before.’
EOSPRINT 2.0 easily integrates into CAD and CAM as well as ERP and MES environments. SIEMENS is the first of EOS's partners to offer the module through its SIEMENS NX software package.
