Nano-3D Manufacturing Technology with Piezo Mechanisms and Laser Lithography

3D printing and additive manufacturing are gaining traction in prototyping and industrial manufacturing of complex parts. Typical 3D printers can produce feature sizes down to a few 10 microns. Significantly higher resolution is available with a new laser lithography system. Here the production of complex three-dimensional micro- and nanostructures is based on photosensitive materials. In […]

High Performance Motion Control – Systems Approach Provides Nanometer Precision for Industrial Applications

High performance motion control plays a key part in positioning and handling applications, such as those in semiconductor manufacturing, laser and materials processing, optical inspection systems, additive manufacturing or industrial digital printing. In addition to providing reliability and robustness, deterministic behavior with minimized latency, high-speed synchronization with external devices, such as lasers and cameras, is […]

Metrology for Precision Motion Systems at PI USA

1.  Introduction When building high precision positioning systems using our PIglide air bearing products, performing the metrology and testing is one of the most critical steps in the process. Only with proper metrology can we verify that our products and systems meet the specifications that our customers demand. In this article, we discuss the various […]

Improving Accuracy of Long Travel Linear Positioning Stages with Error Mapping

Linear encoders significantly improve the accuracy and repeatability in stepper or servo-motor positioning stages based on lead or ballscrew drives – they remove drivetrain based play, backlash, and screw pitch errors. But even the best linear encoders are not perfectly linear. As long as these linearity errors are repeatable, there is a way to reduce […]
