Which laser suits wedding return gifts
For wood, acrylic, stainless steel, brass, a CO₂ laser (10.6 µm) is the usual choice. A CO₂ laser works at a wavelength that organic materials absorb well, including wood, leather, acrylic, paper, cork, fabric and glass. It removes or darkens a thin surface layer to leave a clean engraved mark.
A CO₂ laser does not mark bare metal on its own. Metal needs a fiber laser, or a special marking compound applied before a CO₂ pass.
When a Fiber laser makes sense
A fiber laser works at a wavelength that metals absorb well. It marks stainless steel, brass, aluminium, anodised aluminium and coated metals, and many hard plastics, with a permanent mark and no consumables. For wedding return gifts, consider it if your range includes materials the CO₂ laser does not handle well, or if you need a different finish.
Setting up the job
Mixed-material orders are common. If you expect both wooden and steel return gifts, plan for both a CO₂ and a fiber source, or start with the material your customers ask for most.
What to check before you buy
- Material match. Confirm every material you plan to sell (wood, acrylic, stainless steel, brass) with a test mark before deciding on the laser source.
- Marking area. Flat items can be batch-marked on a jig plate. Plan the layout so one run fills the marking field.
- Power. For marking and engraving gift items, galvo CO₂ markers commonly run between 30 W and 60 W. If you also need to cut shapes or work on large sheets, look at a flatbed CO₂ machine with a moving gantry, which is a different class of machine.
- Software. Check that the software imports vector files and name lists from a spreadsheet, and handles photo engraving if you plan to offer it.
- Fume extraction. Every laser marking job releases smoke or fine particles. Budget for a proper extractor and ventilation from day one.
- Power supply. Use a voltage stabiliser or online UPS. Unstable supply can damage the laser source and controller.
- Safety. Open galvo markers need protective eyewear rated for the laser's wavelength, or an enclosure. Never laser PVC, vinyl or unknown plastics, because some release corrosive and toxic gas.
