Precise laser knifelike and engraving of timber plywood MDF Balsa Sir Henry Joseph Wood and many Trotec wood cutting lasers for press cutting toys and souvenirs made of. Wood engraving with a laser system allows you to easily engrave hardwoods mdf plywood and more. Wood is the general name given for the fibrous structural material derived from tree trunks, roots, and branches.
On a chemical level, wood is comprised of cellulose and lignins, two of the most abundant organic materials on earth. Laser cutting is the complete removal and separation of material from the top surface to the bottom surface along a designated path.
Laser engraving is the process by which material is removed from the top surface down to a specified depth. When using DLMPA® technology to ablate material, enough energy is applied to vaporize a significant quantity of material. Multiple processes can be applied to wood without having to move or re-fixture the material. If you don’t want to risk your fingers or invest in heavy cutting equipment, you can get photos made into wood carvings from services such as Laser Engraved Memories and Touch of Wood. Wood engraving is one of the most popular applications for the laser because it can encompass so many different products. They are a great deal put-upon to make trophies and awards construct acrylic signs for businesses and slew ampere variety of materials to make art prototypes and products.

Looks like you're using an old, unsupported browser (Internet Explorer Firefox, Chrome, Safari, or Internet Explorer 10. Material is removed completely from the top to the bottom surface or partially from the top of the material down to a specified depth.
This leaves a dark residue and is caused by partial combustion of wood fibers as previously discussed. The example demonstrates how processes can be combined to cut square and round shapes, engrave characters and textures, and mark fine detail with cherry wood in one manufacturing step using DLMPA® technology. Processing wood with a CO2 laser generates vapors containing carbon monoxide, acrolein, and formaldehyde, primarily from the combustion of cellulose compounds.

Using a CNC router, a Finnish artist bored out tiny holes in a piece of black plywood to resemble an image.
He has been covering the photographic world for the past ten years for a variety of publications including PDN, This Week in Consumer Electronics and Digital Photographer. From cabinetry to photo frames to knife handles, our laser systems are used in almost every woodworking category you will run across.Can I engrave all types of wood? The primary factor affecting the results of using Digital Laser Material Processing (DLMPA®) Technology with wood is the density and the uniformity of its density. By continuously varying the laser power, laser engraving can be used for textures, photographs and information, such as text and numbers.
By reducing the laser power, the wood can be darkened without substantial material removal. Other high boiling point solids and particles derived from the incomplete combustion of lignins will also be generated.

Our machinery works extremely well with all types of woods, from maple to exotic hardwoods.

When wood absorbs laser energy, it rapidly converts optical energy into molecular vibrations (heat). In general, charring and edge discoloration are proportional to material thickness and inversely proportional to laser wattage. The example shows how the laser energy can be controlled to remove material to a controlled depth.

The most useful effects of laser energy with wood is material ablation and material modification. For thinner sections of wood cut with higher power, the edge may exhibit a brown, sticky residue that can be removed or reduced with water and a soft brush.

Alternatively, it may be treated with a filtration system first and then routed to an exterior environment.
While a maple plaque may give you a lighter engraving, cherry can give you very rich, dark colors where engraved. Laser Engraving Woodcraft Laser Engraving Services Customize operating theatre personalize your tool investments with our new laser engraving service.
However, other factors such as climate and soil conditions also play a role in the densification of wood fibers.
Thick sections of wood cut slowly with lower power lasers will char and cannot be cleaned easily. Wood is perhaps the most versatile natural product used by societies throughout the ages for its aesthetics and physical properties. The material just outside of the laser's spot or path will conduct some heat, but not enough for complete and thorough combustion and ablation. It is often desirable to clean the top surface and leave the residue to dry in the engraving as this enhances contrast. However, you can also clean the engraving with water to improve the appearance of the natural wood grain.
However, many of these properties are anisotropic and maximum utility and beauty is achieved when the wood grain is oriented perpendicular to the surface. Some of these combustion products are water soluble, meaning the dark residue can be partially removed with water and a washcloth or plastic brush.
Laser cutting wood is demonstrated in the example with a square joint and rounded corners laser cut from cherry wood. The basic capability shown can be extended to nearly any shape, even complex and closely-spaced cuts.
