Step by step

Step 1

Step 1: Design

Import our graphic and adapt it to your requrements. We have already tested cutting techniques for bending applications for you. In our Tips & Tricks "Kerf Cut" you'll find further examples of how you can use this application.

Print Settings:

Process mode	Resolution	Cut line
Vector Job	1000dpi	No

Halftone	Others
Color	Optimized Geometries, Inner Geometries first

Step 2

Step 2: Laser processing the wood veneer

Place the honeycomb cutting table in your Trotec laser and attach the small nozzle to the laser head. Place the walnut plate in your laser and cover the remaining working surface. The parameters may vary depending on the laser machine used and available laser power.

Laser parameters:

Color	Process	Power (%)	Speed (%)	ppi/Hz
Red	Cut CO₂	100	1.2	1,000

Passes	Air Assist	Z-Offset	Advanced
1	On	0mm	-

We explain in our Tips & Tricks why you should choose the right nozzle for this application. How to choose the right nozzle.

Step 3: Send the graphic

Send the graphic for the TroLase Foil decoration to your Trotec Laser machine using the following print settings:

Process mode	Resolution	Cut line
Vector Job	1000dpi	No

Halftone	Others
-	Optimized Geormetries, Inner Geometries First

Step 4

Step 4: Laser process the TroLase Foil

Remove the honeycomb cutting table and install the acrylic grid cutting table and the large nozzle. Insert the TroLase Foil into the laser and cover the rest of the working area.

Laserparameter:

Color	Process	Power (%)	Speed (%)	ppi/Hz
Red	Cut CO₂	20	1.0	1000

Passes	Air Assist	Z-Offset	Advanced
1	On	0mm	-

Tip:

It is especially important to closely monitor the vacuum with the thin TroLase Foil to make sure a flat surface is maintained throughout the laser process.

Step 5

Step 5: Cleaning and assembly

Clean the two separate parts with a damp cloth. It is also a good idea to clean the back of the wooding ring so that the napkin does not get dirty later.

Keep the wooden napkin ring flat and glue the TroLase Foil about half off.

To make sure that the overhanging half does not stick to the napkin, we scored and removed half of the adhesive foil on the back with a craft knife. To finish, form a ring around a cloth napkin and secure it with the circular connector.
