Extending the Field — Wide-Format Scanning and X-Y-Z Stitching

Large area laser marking systems combine high-power fibre or CO₂ laser sources with wide-format galvanometer scanning systems, precision X-Y-Z motion control, advanced optical delivery systems, integrated vision and alignment systems, and modular designs for scalability. This innovative approach enhances throughput, marking consistency, and operational flexibility, making them ideal for industries handling large or multiple products.

The fundamental extension mechanism is field stitching: the galvanometer scanner marks within its native field, then the X-Y-Z motion system repositions the scanner head or workpiece by precisely one field width, and the scanner marks the adjacent field. The stitching algorithm ensures that the repositioning step is accurate to sub-pixel precision so that marks crossing the boundary between adjacent fields are seamless — no visible gap, overlap, or alignment discontinuity between successive fields. This stitching approach can tile the scanner field across a total marking area many times larger than any single field, limited only by the X-Y motion range rather than the galvanometer’s optical aperture.

Core System Components

• High-Power Fibre Laser Source (for metals): the marking energy source for metal components, panels, and industrial parts
• CO₂ Laser Source (for non-metals): for composite panels, wood, glass, ceramics, and non-metallic construction and solar materials
• Wide-Format Galvanometer Scanner: high-speed, wide-area coverage with the pinpoint precision maintained within each field
• Precision X-Y-Z Motion Control: accurate, sub-micron-precision repositioning for seamless field stitching across the expanded marking area
• Advanced Optical Delivery System: uniform beam distribution across the expanded marking area to maintain consistent mark quality at all positions
• Integrated Vision and Alignment System: real-time alignment of the stitching pattern to the actual component position and quality verification of each marked field
• Modular Frame Design: scalable architecture for flexible integration with different total marking area requirements and production line configurations
• FlyCAD Software (9-axis, MES/ERP, lifetime free updates): manages the field stitching sequence, mark content, variable data, and production integration

Engineered for Performance at Scale

High-power fibre lasers for metals, CO₂ lasers for non-metals, a large-format galvanometer scanner with high-speed wide-area coverage, advanced optical delivery for uniform beam distribution, precision X-Y-Z motion control for accurate large-area positioning, integrated vision systems for real-time alignment and quality verification, and a modular scalable frame design that adapts to different total marking area requirements.

Efficiency at Scale — Single Pass, No Repositioning

Mark large surfaces in a single workflow without repositioning the component. Simultaneous multi-item marking of batch trays boosts throughput. Reduced cycle times ideal for high-volume production where the alternative is sequential single-field marking with manual part loading between each piece — the large-area system marks an entire batch tray in the same time the single-field system marks one component, or marks a full oversized panel without disassembly and sequential marking of sub-sections.

Precision Without Compromise — Seamless Field Stitching

Consistent marking quality maintained across wide fields through advanced galvanometer scanning, dynamic beam control, and real-time surface mapping. Supports intricate designs, logos, QR codes, and serial numbers across the full field at the same resolution as a single-field system. Seamless stitching ensures flawless patterns with no overlaps, gaps, or visible field boundaries — the stitching algorithm’s sub-micron-precision repositioning step produces transitions invisible in the finished mark, even on high-density barcodes and fine-line logos that cross the boundary between adjacent fields.

Versatile Across Materials and Sizes

Compatible with metals, plastics, ceramics, composites, wood, and glass. Handles everything from small components arranged on batch trays to oversized single panels exceeding a metre in any dimension. Fully customisable for branding, traceability, and decorative applications across the range of large-format marking requirements encountered in aerospace, automotive, solar, and construction materials manufacturing.

Cost-Effective Automation for Large-Format Production

Minimises manual labour through intelligent automation of the stitching sequence and batch tray marking workflow. No consumables — no ink, solvents, or wear parts. Lower operational costs with high uptime and minimal maintenance. For Indian manufacturers currently handling large component marking through multiple single-field passes with manual repositioning between each, the large-area system’s elimination of manual repositioning steps directly reduces operator headcount requirements and cycle time at the marking station.

Aerospace and Aviation

Aircraft structural components combine large surface areas with strict traceability requirements and demanding material specifications that conventional single-field laser marking cannot address in a single setup:

• Aircraft fuselage panel marking: permanent serialisation and compliance marks on large aluminium and composite fuselage skin panels that exceed any single-field laser marker’s coverage, supporting HAL and India’s expanding aerospace manufacturing sector
• Traceability on turbine components: batch-tray marking of turbine blade sets, vane arrays, and fastener batches in a single marking cycle, with each component receiving its unique serial number and inspection mark from the MES/ERP-driven variable data system
• Safety compliance detail engraving: permanent safety, certification, and part number markings on large aerospace structural components meeting AMS and MIL-STD direct part marking requirements at the throughput rates required for aerospace manufacturing batches

Automotive Manufacturing

Automotive body panels and structural components combine large surface areas with the high-volume production rates and IATF 16949 traceability requirements that make single-field sequential marking impractical for maintaining takt time:

• Body panel and frame numbering: large-area laser marking of body-in-white panels, door skins, hood inners, and structural frame sections with VIN-related serialisation and traceability codes in single marking cycles without repositioning, supporting Indian automotive OEMs and stamping suppliers
• High-speed batch part serialisation: batch-tray marking of automotive component sets — brake components, engine brackets, suspension parts, trim clips — in single marking cycles that mark an entire tray load simultaneously
• VIN engraving on oversized components: permanent vehicle identification marks on large chassis sections, crossmember assemblies, and body structural components where the mark location and panel dimensions exceed standard single-field system coverage

Solar Panel Production

India’s rapidly expanding solar manufacturing sector — driven by PLI scheme incentives for domestic module production — requires large-area marking capability for photovoltaic module identification, certification, and traceability:

• Photovoltaic cell serialisation: large-area marking of silicon wafer batches or module glass substrates with cell serial numbers and manufacturing traceability codes, using the batch-tray capability to mark multiple wafers or cells per cycle across the expanded total field
• Panel certification and compliance markings: permanent IEC and BIS certification marks, power output specifications, and manufacturer identification on full-size solar module glass or backsheet surfaces that typically span 1–2 metres, addressed in a single stitched marking workflow without repositioning the module
• Batch marking of solar arrays: marking of module component sets — junction boxes, frame sections, mounting hardware — in batch tray configurations that mark complete module assembly component sets simultaneously

Construction and Building Materials

Large-format construction materials — tiles, concrete panels, glass facades, and architectural stone — require marking systems that match their scale for identification and decorative applications:

• Concrete, tile, and stone marking: permanent identification, certification, and decorative engraving on large-format construction materials using CO₂ laser sources for the organic and silicate-based materials common in construction products, relevant to India’s construction materials manufacturing sector
• Large panel batch processing: batch-tray marking of tile sets, paving slab batches, and cladding panel arrays in single marking cycles for production traceability and compliance marking in construction material manufacturing
• Architectural decorative engraving: large-scale decorative patterns, brand marks, and custom engravings on architectural glass, stone facade panels, and decorative tile at scales requiring the full large-area stitching capability
