Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge. While typically used for industrial manufacturing applications, it is now used by schools, small businesses, architecture, and hobbyists.
Laser engraving can also be used to create works of fine art. Generally, this involves engraving into planar surfaces, to reveal lower levels of the surface or to create grooves and striations which can be filled with inks, glazes, or other materials. Some laser engravers have rotary attachments which can engrave around an object.
New technology has also enabled laser-cutting of wooden or acrylic jigsaw puzzles. The advantage is that the puzzle can be custom-cut to any size or shape, with any number or average size of pieces. Many museums have laser-cut acrylic puzzles made of some of their art so visiting children can assemble puzzles of the images on display.
With state-of-the-art machinery it is easy to have a simple, single item complete in under ten minutes. The engraving process with diamonds is state-of-the-art since the 1960s. Today laser engraving machines are in development but still mechanical cutting has proven its strength in economical terms and quality.
where t is the depth of cut, P is the laser beam power, v is the cutting velocity, and d is the laser beam spot diameter. [5] The depth of the cut is also influenced by the workpiece material. The material's reflectivity, density, specific heat, and melting point temperature all contribute to the lasers ability to cut the workpiece.
The laser also has the ability to melt and seal the edges of fabric with the heat of the laser. This helps against fabric fraying during the creation process. [14] Additionally, using a laser for cutwork enables the embroiderer or creator to achieve unique designs such as an 'etched look' by changing the depth of the laser cut into the fabric.
