Introduction

Laser engraving is a versatile and precise method for etching designs onto various materials. In addition to traditional engraving, it is possible to achieve a spectrum of colors on certain materials by adjusting specific parameters of the laser machine. This article provides insights into the colors that can be engraved with a laser machine, the parameters affecting the outcome, and solutions offered by Langsheng Laser Company.

Laser Engraving Basics

Laser engraving involves using a focused laser beam to remove material from a surface, creating a design that is incised into the material. The basic factors influencing the engraving process are the power of the laser, the speed at which the laser moves, the frequency of the laser beam, and the characteristics of the material being engraved.

Color Engraving With Lasers

While laser engraving is traditionally a monochrome method, specific techniques and parameters can produce colors on certain materials. The colors are primarily achieved through a process known as laser-induced oxidation or changes in the material's surface structure. Metals, especially titanium, and stainless steel, offer the best results for color engraving.

Parameters For Achieving Colors

The colors that can be achieved depend on several laser parameters:

• Laser Power: Lower power settings can create lighter colors by minimizing material removal and allowing oxidation to occur.
• Speed: Slower speeds can result in deeper engravings and potentially more vibrant colors. Precise control is necessary to avoid overheating.
• Frequency: Higher frequencies can affect surface finish and color intensity. Typically, a frequency of 20-200 kHz is suitable for color engraving on metals.
• Focus Depth: Adjusting the focus can influence the color spectrum achieved. A smaller focal point can increase energy density, impacting color.

Metals like titanium can produce a wide range of colors from blues to greens and purples when these parameters are finely tuned. Stainless steel can achieve yellows, blues, and browns.
