A lantern is the perfect decoration for a range of occasions, including weddings Christmas or Birthdays. In this tutorial we take you step by step through the process to create a unique laser engraving on a lantern for a personalised decoration.


Preparation

Materials used:

  • Glass lantern, angular, 10x10x10 cm
  • Candle, height ca. 8 cm, diameter ca. 6 cm
  • Paper towel

Laser machine used:

  • Speedy 400 laser engraver
  • 120 Watt
  • 2" lens
  • vacuum table

Whilst we have used a Speedy 400, any Speedy laser engraving machine can be used to create this sample. 

Tips:

In this example we have chosen to laser engrave the glass using damp kitchen paper. This will prevent the glass from splintering during the laser engraving process

When preparing the lantern, you'll need a sheet of kitchen paper, water and either a sponge or spray bottle. Start by placing a single, thin layer of kitchen paper on the area the laser machine will engrave and moisten it using the your sponge or spray bottle. To ensure best results when laser engraving, ensure that there are no folds or air bubbles in the paper. 

Tips and tricks for glass engraving with the laser


Step by Step

Step 1: Import/create laser template

Start by creating your own design or use our free template for the design. The job should be sent to the laser using the settings below.

Print settings

Process mode  Resolution Cut line
Standard 500dpi none
Halftone Others
Colour Optimised Geometries

Step 2: Laser engraving

The next step is to create the parameter settings. Our suggested parameters will vary depending on your laser machine and the available laser power. In order to prevent early drying of the kitchen paper, the blowing is deactivated during the laser engraving process.

Position the lantern on the vacuum table. Place a sheet of paper under the glass to prevent any possible scratches on the glass. For an optimal laser engraving result, the surface to be engraved must have an even height. If the wind light has a bevelled shape, please compensate for any differences in height.

Step 3: Finishing

Once the laser engraving is completed, remove the glass from the laser machine. The engraved surface can now be carefully cleaned with a damp cloth.

Once cleaned, place a candle in the lantern.



Inspiration

To accentuate the laser engraving result, a dark, strong colour of the candle is recommended.
