Maximizing Working Volumes While Minimizing Spot Sizes

Greater precision is possible with the AGV3D because it features direct-drive dynamic focusing optics with high-resolution feedback. The dynamic focusing module’s (DFM) high stiffness, excellent dynamics and superior positioning performance minimize positioning errors, resulting in highly optimized laser processing capabilities. Additionally, AGV3D offers the largest motorized working volume available of any 3D scanner, providing versatility and efficiency in your manufacturing process while eliminating the need to stop production for manual focal adjustments. AGV3D can quickly and easily place a sharply focused spot anywhere within the working volume.

Key Applications

AGV3D excels in applications that involve processing 3D volumes, varying the working distance and flattening a large field of view beyond the capabilities of F-theta lenses, including:

• Medical device manufacturing
• Additive manufacturing and 3D laser sintering
• Cylindrical and tubular processing
• Cutting, trimming, drilling and scribing
• Deep engraving
• 3D laser micromachining and microstructuring
  

  Innovative, Direct-Drive Focusing

  Until now, many commercially available 3D laser scan heads have employed a focusing axis arrangement that uses a rotary galvo motor and a tangent-arm drive to translate the focusing optics. These indirect-drive designs tend to be prone to thermal instability and lack the dynamics and precision needed to tackle the most challenging applications.

  As the only scanner on the market with a DFM based on high-performance, direct-drive motion technology, AGV3D offers unmatched stiffness, accuracy, repeatability and stability. The AGV3D’s DFM is equipped with a direct-drive linear focusing axis for superior dynamic performance and smooth, precise motion, along with high-resolution position feedback for accurate and repeatable focusing. AGV3D is also available with air- and water-cooling features for maximum thermal stability in demanding applications.

  Superior Usability and Higher Throughput

  AGV3D offers the largest motorized working volume available across a variety of laser wavelengths, making it easy to follow 3D contoured surfaces, adjust working distances and maintain optimized focus on the fly. Unlike designs that require tedious manual DFM adjustments to change the usable working volume, AGV3D has two simple, user-selectable field configuration settings that cover fields of view ranging from 100x100 mm to 1000x1000 mm and beyond. Your AGV3D will arrive conveniently pre-set with your desired working-volume configuration, and you have the freedom to quickly and easily switch between settings, too. With a novel optical design that allows for the smallest possible focused spot size, AGV3D enables you to process your workpiece precisely and efficiently. Optional air- and water-cooling features improve thermal stability over time to deliver consistent processing results and allow for more aggressive dynamic performance and higher throughput.

  Engineered for System-Level Integration

  AGV3D is ideal for integrating 3D laser processing with a precision machine. The compact, lightweight design allows you to use smaller, more efficient supporting motion mechanics. This facilitates more effective machine design, enhanced system dynamics and a smaller overall machine footprint.

  AGV3D is compatible with many laser wavelengths, giving you more freedom to choose the right laser for your process. Depending on your process needs, AGV3D is available with different aperture options for minimizing focused spot size and maximizing dynamic performance.

  Unlike many suppliers that leave the final integration of the scan head and the DFM to the customer, Aerotech ships AGV3D as a fully assembled scanning system, saving you time and effort. AGV3D can also accommodate an extensive selection of commercially available F-theta lenses for applications that involve processing parts with relatively little height or thickness variation or for multi-layer processing applications. Telecentric lenses may also be used to maintain beam normalcy to the work surface.

  One Controller for All Motion

  Aerotech’s controllers make it easy to synchronize and coordinate AGV3D’s motion with other motion axes in the system, including servo- and stepper-motor stages, piezo nanopositioners, and hexapods. Because all devices are programmed and controlled from the same interface, your user experience is seamless and intuitive. This synchronization also enables advanced control capabilities such as Infinite Field of View (IFOV) and Position Synchronized Output (PSO).
