3D Laser Marking · 1200 × 1200 mm in One Pass

3D Large-Format Laser Marking Machine

Most large-format marking isn't really large-format — it's several small marks stitched together. Line up the rail, mark, shift the part, line up again — and pray the seams don't show. This machine covers 1200 × 1200 mm in a single pass, no overhead beam, nothing to stitch. And because the galvo is 3D, curves, slopes and relief all happen inside that same field — not just flat marks.

What Fits in a 1200 × 1200 mm Field?

Parts too big to fit a normal marker in one go — plus curves and relief inside that same field. If yours isn't here, send the drawing — we'll tell you straight whether it suits.

Curved Components

Dashboards, housings, curved pipe — the focus follows the surface.

The Core Difference

Why Beam-Free Matters

Conventional large-format systems put the marking head on a moving rail. That rail is where the problems start.

Rail-Based SystemBeam-Free Design
Large parts get marked in sections, then stitched
The whole 1200 × 1200 mm field is covered in one operation
Every reposition is a chance for the seam to land visibly wrong
No repositioning means no seam to line up in the first place
Rails, guides and drives wear — and the mark tells you when they do
Fewer moving parts, so less to service and less drift over time
Setup time eats the shift before the first good part comes off
Load, position once, run — the throughput gain is mostly setup you stop doing
Laser Source

Fiber, UV or CO₂?

The material decides this, not the budget. Tell us what you're marking and we'll pair the source to it before we recommend a configuration.

Best for metals

Fiber

  • Steel, stainless, aluminum, brass
  • Deep engraving and relief
  • Coated and anodized metal
The default for metal work, and the one most large-format buyers end up with.
Best for heat-sensitive materials

UV

  • Plastics that discolour under heat
  • Glass and delicate surfaces
  • Electronic and precision components
  • Fine detail where fiber goes too aggressive
Cold marking. If your part discolours or warps under a fiber laser, this is the one you want.
Best for non-metals

CO₂

  • Acrylic, wood, leather, paper
  • Glass and ceramics — the workhorse choice, not UV
  • Large decorative panels
Wrong tool for bare metal. If your work is mixed, tell us the split before you choose.

Result & Materials

Field Size Is Only One Part of the Result

A large working field gets your part under the beam. What comes out depends on four other things — which is why we'd rather run your actual file than quote from a spec sheet.

1
Design File

A weak STL or grayscale file caps the detail before the laser starts. Most disappointing results trace back here.

2
Material & Source

Fiber, UV and CO₂ each behave differently on the same part. Mismatch the two and nothing else helps.

3
Field vs. Detail

The larger the field, the coarser the spot. Fine detail may want a smaller lens even on a big machine.

4
Depth & Layers

Every extra tenth of a millimetre is another set of passes.

Watch the Machine Work

For large-format work, the finished panel and the cycle time tell you more than a field-size number on a spec sheet.

One thing worth saying before you pick a field size: bigger is not automatically better. The larger the marking field, the coarser the focused spot — so fine detail can come out sharper on a smaller lens. Send us your part size and the finest feature on it, and we'll match the field to that.
Before You Order

Let Us Check Your Part First

On a machine this size, the wrong field or the wrong source is an expensive mistake. A test settles it.

Send us the job, not just the machine model.

Before we recommend a field size or a laser source, we normally ask to see the part and the marking file. Material, size and required depth change the answer completely.

Plenty of buyers come asking for 1200 × 1200 and leave with a 600 × 600 — or the other way round. We'd rather get that call right than close the bigger order.

Send Us

  • Material
  • Part size
  • Photo or drawing
  • Marking or relief file
  • Required depth
  • Quantity you plan to run

We Will Check

  • Whether you need the full 1200 × 1200 mm
  • Fiber, UV or CO₂ for your material
  • The result to expect
  • Approximate cycle time (after testing)
Can it really mark 1200 × 1200 mm without stitching?

Yes — that's the point of the beam-free design. The full field is covered in one operation, so there are no section joins to line up and no seam to hide.

Do I need the full 1200 × 1200 mm, or is a smaller field enough?

If the parts fit inside a smaller field, a smaller system does the job for considerably less. This machine earns its price on genuinely oversized parts, or deep relief where focus range is the limit.

Which laser source should I choose?

Metal is fiber. Heat-sensitive plastics and glass lean UV. Acrylic, wood and other organics are CO₂. If your work is mixed, tell us the split and we'll advise before you commit.

Can it engrave curved and stepped parts?

Yes, within the dynamic focus range. Send a drawing showing the height difference and we'll confirm it with our engineer before you order.

How much maintenance does it need?

Less than a rail-based system — there's no gantry to keep aligned and fewer moving parts to wear. The trade-off is that galvo replacement, if it ever comes to that, costs more.

Can I test my own part first?

Yes. Send the material, file and part size — we run the test, film the result, and send you the video with cycle time.

Not Sure Which Field Size to Buy?

One message and we'll work it out with you.
