Find out everything worth knowing about your production parameters in less than 3 seconds from the ScanFieldMonitor (SFM). You’ll soon find that it is as innovative and creative as the 3D production industry itself. A revolutionary patented measuring process from PRIMES for additive manufacturing processes characterized by a small glass structure, a compact design, and our innovative measuring principle make the ScanFieldMonitor a multifaceted, nimble handheld turbo for laser beam diagnostics and process optimization. A piece of glass with a specific measuring structure is what distinguishes the innovation of the ScanFieldMonitor (SFM). A photodiode captures the scattered light while scanning the laser beam over this structure and uses this information for fast laser beam characterization. Not only will it tell you the width of the beam on the measuring plane, but it will also allow you to reconstruct the path, position, and length of the beam and determine its speed of movement.
The ScanFieldMonitor meets the demands of scanner-specific measuring tasks, including aspects such as surface evenness, pincushion distortion, focal point shift, or precision of the position and marking speed. The device operates by detecting the scattered laser light on a structured glass plate and is therefore independent of the optical power. This makes it possible to reconstruct the travel path taken by the light and calculate the beam width at multiple positions across the working area. All of the variables mentioned above can be measured with high resolution and reproducibility.
The greatest advantage of the SFM is that it combines multiple measuring tasks in a single device. This saves the user time and money, regardless of wether you’re a mechanical engineer commissioning and maintaining AM machines or a user managing processes and quality. The compact measuring unit with wireless communication enables you to identify properties at arbitrary positions in the working area under actual process conditions.
