| How SCANahead Works
With SCANahead control, the excelliSCAN can always reach the set scanning speed with the maximum acceleration of the scanning head (I. e. within the minimum acceleration time ta). Different from the scanner based on the traditional Tracking Error ts control algorithm (the latter maintains a constant acceleration time regardless of the target speed), the excelliSCAN needs to generate the corresponding control parameters according to the actual situation. |
| Application Advantages
•Productivity is improved due to significantly shorter acceleration phases •Process time is shortened and process parameters remain unchanged. •Digital encoder technology for high profile fidelity and long-term stability-even for demanding scanning tasks •Extremely easy to use due to the Universal Tuning function and automatic delay setting | More information about SCAN-ahead in the video:

| How SCANahead Works
3D Printing Example: Higher Productivity and Accuracy So far, the increase in production efficiency in additive manufacturing has been mainly through the use of multi-head systems or higher power Laser. Modern control technologies such as SCANahead control with scanning laboratories (scanlab) offer additional potential. In additive manufacturing, two-dimensional structures are typically achieved by two-way scribing techniques. In scanning devices employing conventional control systems, most of the process time is devoted to turnaround times for acceleration and deceleration processes. Scanning systems with SCANahead technology can significantly reduce these turnaround times, resulting in a significant increase in productivity. |
