Glass Laser Marking Engraving & Etching By dpss uv laser source

laser is a machine that produces a beam of light through an optical amplification process. Today, lasers have become critical components of the products we use in our daily lives, ranging from bar code scanners to DVD players.

 

In manufacturing, lasers are used for drilling, cutting, and engraving a wide range of materials. In glass manufacturing, for example, laser engraving and etching provide several possibilities for personalization without changing the characteristics of the glass.

 

Laser engraving cuts out a portion of the material, leaving a cavity that reveals a design, with the engraved part noticeable through sight and touch. Laser engraving is performed with a high-heat laser that vaporizes the material. Engraving depths typically vary between 0.02″ and 0.125″ for harder materials.

 

Laser etching, on the other hand, does not cut into the material but instead removes only the top layer using a less powerful machine. The depth of the “cut” is usually no more than 0.001″.

 

In fact, etching is a subset of engraving and is considered a chemical process, while engraving is regarded as a physical process. Both techniques have become popular for adding images, logos, and numbers on glass. In fact, an entire cottage industry has sprung up around creating novel or custom engravings for glass. Businesses like ClinksDrinks as well as a whole slew of Etsy retailers offer laser engraved glass products with pop culture references.

 

In this article, we’ll take a deeper look at both laser engraving and etching, including how they work, their benefits, and how they’re executed.

In a nutshell, the high-temperature laser beam vaporizes the material and physically cuts into it, leaving a cavity. With glass, this works because of its inner composition.

 

Glass is made by heating silicon, which melts at high temperatures and turns into a thick fluid. The molten material is then manipulated in various ways, causing it to trap air and moisture.

 

Whenever a laser beam hits the glass, the air and moisture between elements of silica and metal react, not the other glass elements like silicon. Specifically, they expand, and since the glass is rigid, this causes microscopic fractures on the surface of the material. It is the resulting fracturing and chipping that we see and feel as engraving.

 

Engraving Curved Glass

Lasers are generally easier to use on a flat surface, where there is a given focal length and distance between the lens and the surface of the material.

 

Engraving a curved surface (like bottles, vases, and steins) can pose a challenge, but there are workarounds allowing for some flexibility. For example, using a rotary attachment is an option. Plugged into a laser machine, it allows the glass object to rotate as the laser does its magic. Naturally, complex angles and variations in curvature can still cause problems.

 

Neatness & Cleaning

Although engraving glass comes down to fracturing and chipping the material, the goal is to produce a shard-free pattern as much as possible. To do this, most engravers place wet paper towel or newspaper over the glass.

 

각인 후에는 항상 청소가 필요합니다. 이를 위해 파편이 있는 경우 소독용 알코올과 종이 타월 또는 네일 브러시를 사용할 수 있습니다. 다른 처리 옵션에는 표면 영역이 거칠어지는 것을 방지하는 데 도움이 되는 적용 테이프 사용이 포함됩니다.

 

에칭은 어떻게 작동합니까?

레이저 에칭은 조각의 하위 집합이며 절단 깊이가 일반적으로 0.001인치를 넘지 않는다는 점을 제외하면 동일한 방식으로 작동합니다. 이는 반사성과 같은 속성에 영향을 주어 표면의 모양을 변경하는 것 이상을 수행하지 않습니다. 레이저 에칭은 때때로 레이저 마킹과 레이저 제판 사이의 스위트 스폿으로 간주되며 얇은 재료나 보석에 이상적입니다.
