EOS M 290 Meltpool Monitoring IPC

Known in France and Europe for more than 15 years, as a leader for metal-based additive manufacturing, IPC recently acquired the meltpool monitoring system, called EOSTATE MeltPool, developed by EOS (global leading manufacturer for SLS and DMLS processes) installed on the EOS M 290. IPC has now the first DMLS machine equipped with an EOSTATE Exposure OT monitoring system and EOSTATE MeltPool outside Germany. These two devices are complementary.

As part of our partnership with EOS, which began in 2001, IPC will test this new monitoring system with tool steel (maraging steel and stainless steel Corrax) which are commonly used at IPC for inserts with conformal cooling channels in plastic injection moulds.

The EOSTATE MeltPool monitoring system consists of photodiodes that capture the emitted light of the laser-sintering process. This allows to monitor the meltpool area during the building process.

Nowadays, one of the major problematics in additive manufacturing is the material and the shape are processed simultaneously. As for now it is impossible to define if the created material meets specifications without destructive testing or costly CT scans after the build process. Thus, this online quality assurance tool avoids time-consuming and expensive post-production testing without adding production time.
