Thanks to their high level of customer intimacy and technological familiarity, voestalpine develops tailor-made solutions for their plastic injection molding (PIM) customers. These are manufactured with the EOS M 290 system and optimized with EOS Monitoring solutions enabling a faster development of the process parameters, reduction of printing costs due to fewer job iterations and a reduction of the quality assurance costs.

EOSTATE Exposure OT and MeltPool Monitoring gave us a deeper understanding of the interactions taking place between the various factors that influence the LPBF process. Not only were we able to minimize the development cycles of novel materials during the qualification phase but we were also able to benefit from faster build rates and lower lead times for production.
Our DMLS systems are all equipped with EOSTATE Base out of the box. The software monitors all system-internal sensors and indicates whenever a quantity such as the oxygen concentration or laser power is not within the target range. The following factors are also monitored: laser and scanner status with automatic scanner self-calibration, cooling system, electrics including the power failure protection, position of the build platform, dosing system and collection containers, status of the air circulation system, process chamber and ambient atmosphere, as well as the temperature of the build platform. If any of these quantities deviate from a predefined corridor, the build process is stopped and the user is notified.
Another prerequisite for a stable build process in 3D printing is a uniform and complete coating of the build platform at every layer. The PowderBed module is the solution for monitoring the current powder bed. After each layering and exposure phase, an integrated camera takes a picture of the build area and identifies any irregularities, such as an incomplete powder layer, grooves or cavities. This reveals any uneven or incomplete layering steps. If there are any problems, the build process can quickly be stopped.
The EOSTATE plug-in optimizes the application, allowing the recordings to be exported as a video clip to the work computer.
EOSTATE MeltPool provides high-resolution information about the melt pool dynamics, making it the ideal complement to Exposure OT. Using on-axis sensors integrated into the beam path, MeltPool measures the emissions of the melt pool, giving deeper insight into the 3D printing process. Various individually adjustable analysis parameters make it possible to evaluate the part quality. The features of MeltPool make it ideal for users who want to improve their research and development processes or optimize their production methods.
The high complexity of additively manufactured parts places special demands on quality assurance. Downstream testing methods such as X-ray or computed tomography (CT) quickly reach their limits. In many cases, testing becomes more expensive than the actual manufacturing – several times over.
Exposure OT is a unique and cost-efficient alternative: As the world’s first commercial testing solution based on optical tomography, Exposure OT enables non-destructive testing after the build process. Regardless of the part size, Exposure OT records and analyzes the quality-relevant 3D printing process data with a sCMOS industrial camera. The camera captures the entire build space and measures the quality-relevant heat emissions in real time. Exposure OT then generates a list of indicators for the user to evaluate. The analysis algorithm can be adapted to individual requirements, meaning that each user only receives the results that are relevant to them.
Exposure OT enables you to eliminate the high costs of downstream quality assurance procedures. Exposure OT is also a useful tool for application development: the data that it collects can decisively improve series production and process development. This significantly reduces the development times of new products.
