Materials

Stainless steel has an exceptional durability that lends itself better suited to rotary engraving more than most materials, and its ability to not react with most chemicals also allows it to be practical for laser etching. Among these desirable qualities, it is also resistant to corrosion and will not contaminate other materials, making it an incredibly versatile material with a wide range of commercial and industrial applications; containers, control panels, switch and legend plates, signs, elevator panels etc.

Stainless steel is designated via numbering system that groups various grades of stainless steel within a particular series.

Series 200, 300, and 400 lend themselves to be easily engraved, whereas others are better suited for being laser cut or etched. Stainless steels are also classified with machinability ratings that are often compared to other materials, where one metal is an established standard to which all other metals are measured.

Stainless steel can be engraved or etched with the following technologies:


Mild steel (steel containing a small percentage of carbon, strong and tough but not readily tempered), also known as plain-carbon steel, is now the most common form of steel because its price is relatively low while it provides material properties that are acceptable for many applications. Low-carbon steel contains

approximately 0.05-0.25% carbon making it malleable and ductile. Mild steel has a relatively low tensile strength, but it is cheap and easy to form, which makes it ideal for Diamond Drag and Rotary (deep) Engraving.

Lasering aluminum is simple and easy; leaving a permanent mark on the surface without the use of harsh dyes or other chemicals that could damage or compromise the integrity of the material. Due to its properties it has become increasingly popular in commercial and industrial applications for labeling and coding a wide variety of products; pictures, logos, lettering, numbering etc.

Alumamark is a special type of Aluminum frequently used here at Lasercraft and our clients for its ease of use, durability, and quality

of finish. When laser-etched the resulting finish is crisp, sharp, and dark, which is permanently marked in the material itself thus guaranteeing long lasting marking that won’t chip, fade, or scratch off; problems often associated with alternative etching using pastes and chemical burning.

Aluminum can be engraved with the following technologies:


Aluminum alloys are anodized to increase corrosion resistance and to allow dyeing (coloring), improved lubrication, or improved adhesion. However, anodizing does not increase the strength of the Aluminum object.

Some Aluminum aircraft parts, architectural materials, and consumer products are anodized. Anodized Aluminum can be found on mp3 players, smartphones, multi-tools, flashlights, cookware, cameras, sporting goods, window frames, roofs, in electrolytic capacitors, and on many other products both for corrosion resistance and the ability to retain dye. Although anodizing only has moderate wear resistance, the deeper pores can better retain a lubricating film than a smooth surface would.

Anodized / mill finished Aluminum can be engraved or etched with the following technologies:


Acrylic

Acrylic is manufactured in different ways, with the two most common types being Cast and Extruded, which react differently during laser engraving and/or cutting.

Cast Acrylic

Cast acrylic is used for almost all engraving purposes, as the resulting finish provides a noticeable and clean contrast to the clear material, producing a white frosty appearance.

Extruded Acrylic
 
Extruded acrylic, when laser engraved, does not produce images as clean and crisp as cast acrylic does. Thus it is better suited for being

laser cut into dimensional shapes and objects. Its lower melting point produces an almost “flame finished” edge from the laser, one that is noticeably cleaner and smoother in comparison to cast acrylic.

The quality of the engraving is also affected by the purity of the acrylic, in the sense that cheaper more inexpensive brands of acrylic do not cut as clean due to having inconsistent melting points throughout the material.

Wood Engraving

Wood engraving is one of the most popular applications for the laser because it can encompass so many different products. From cabinetry to photo frames to knife handles, our laser systems are used in almost every woodworking category you will run across. Whether you are working with hardwoods, veneers, inlays, mdf, plywood, walnut, alder, or cherry, you can engrave amazingly intricate images with a laser system.

Can I engrave all types of wood?

The laser works extremely well with all types of woods, from maple to exotic hardwoods. Each displays a different quality when engraved. While a maple plaque may give you a lighter engraving, cherry can give you very rich, dark colors where engraved. Trying out different woods can give you very different effects with the same image.

What size of wood piece can I engrave?

Our laser systems range in capacity from 13″ x 25″ (330 x 635 mm) to 27″ x 48″ (685 x 1219 mm). If we can fit your product in our engraving table, we can engrave your item.

Is there a lot of programming involved?

Unlike CNC machines that require extensive programming, our CO2 lasers operate more like printers.

Brass is perhaps the most common metal used in the engraving world. Its gold tone increases the perceived value in the eyes of the customer, which translates into greater sales for you. For many, there is nothing more prestigious than an elegant brass plate affixed to a plaque or trophy.

One of the benefits of working with brass is that it can be exquisitely engraved in a variety of ways to produce different effects. It can be rotary engraved to some degree, as well as burnished or diamond drag engraved.

Brass can be engraved or etched with the following technologies:


Glass laser etching produces a beautiful frosted effect, allowing you to etch custom logos and designs on glass.

Logos, text (and just about anything else!) stands out even more as the laser creates a beautiful, frosted effect that makes your engraved design really stand out against the glass background.

How deep will the laser etch?

Traditional glass sandblasting might allow for deeper marking while lasering creates a lighter etch, but the preferred method for marking glass is still laser etching. The versatility offered by lasering allows us to mark more elaborate, unique, and detailed designs faster, as well as maintaining the structural integrity of the piece.
