New Year’s themed engraving on toys and dishes
Task: Make New Year-themed engravings on toys and dishes
To complete the task, a machine was used with a JPT seal-355 UV laser with a wavelength of 355 nm , with an average power of 3 W – Endurance 3 watt UV (355 nm ) laser module. Link to the site with the possibility of purchasing https://www.endurance-lasers.com/products/3-watt-uv-355-nm-laser-module. Pulse duration at 30 kHz is less than 18 ns . The laser operates in the frequency range from 20 kHz to 150 kHz. To maintain the laser operating temperature (25 °C), a water cooling system is used.
The machine is equipped with a galvanometer RC7110 with a lens “SL-355-110-160-D10-LP” installed on it, having a focal length of 160 mm and a working area of 110 mm by 110 mm.
The machine is controlled using the EzCad program .
General view of the installation
For engraving, two-dimensional vector images in svg format were used .
The width varied depending on the item being engraved and in some cases reached 60mm
Engraving was done by tracing each element of the vector image along the contour followed by filling the contour. The distance between the fill lines was set to 0.05 mm.
