Renishaw, a global engineering technologies company from UK, launched InfiniAM™ Sonic acoustic process monitoring software to complement its InfiniAM software for additive manufacturing monitoring tools at the on-going Formnext 2019 exhibition, the world’s leading trade show for additive manufacturing.
InfiniAM Sonic Software for Additive Manufacturing
The InfiniAM Sonic software for additive manufacturing enables engineers to detect acoustic events within the AM build chamber and turn this data into useful information about build quality. The software is the first of its kind in the AM industry.
The InfiniAM Sonic software for additive manufacturing is installed into the RenAM 500Q system as a factory fit option and includes four acoustic energy sensors to detect vibration in the build,. The sensors detect minute vibrations and collect these sound waves so that they can be heard, viewed and analysed. Using four high frequency sensors in different locations results in a slight time difference, due to the speed of sound. The software uses this to triangulate the position of the noise on the build plate. In addition, the software presents a level of certainty regarding where the noise occurred, and the magnitude. This data can then be combined graphically with other sensor data to build a comprehensive view of the part and the conditions at the time of build.
InfiniAM Sonic works alongside InfiniAM Central and InfiniAM Spectral, which provide improved understanding of build quality, increased confidence in the build process and accelerated process development. The InfiniAM Central mobile app is also available, so that users can receive notifications on their build process in near real-time.

Speaking about the InfiniAM software for additive manufacturing David Ewing, AM Product Manager at Renishaw explained, “The rapid heating and cooling that takes place during an AM build leads to residual stress in the part. While each laser weld results in a small amount of stress, residual stress can build up within the part, and if it increases past the strength of the metal it may lead to a fracture in the support material or part itself.”
He continued, “Renishaw’s InfiniAM software for additive manufacturing makes it a lot easier to understand what is happening during an AM build. Spectral and Central give manufacturers ‘eyes’ inside their AM component and process – now we’ve launched InfiniAM Sonic as the ‘ears’. These tools help engineers to better understand their AM parts and processes, and identify potential causes of defects early on. This is particularly useful whilst developing and validating parts. The more data available, the quicker it is to confirm manufacturing is in specification; root cause investigation is simplified, and if necessary the build can be stopped, saving material and time.”
Renishaw manufactures laser powder bed metal additive manufacturing machines. Its product portfolio includes the RenAM 500Q, a highly-productive machine that features four lasers in the most commonly used platform size.
