FAQ: How to choose laser cutter?

PPI (points per inch) determines how many dots the laser cutter head will place per inch. Image Density determines how far apart two horizontal lines that the laser head travels are spaced.

A laser is able to cut materials such as paper because it can melt, burn, or vaporize materials away. Laser cutting processes can be used to cut a variety of materials, including steel. ... Also, the laser can do this without causing the edges of the paper to have burn or scorch marks.

A new laser cutter can cost anything between £200 and upwards of £1,000,000.

The 2 things you can adjust are usually power 0% to 100% and speed that the laser travels. By adjusting those you determine the cut. Your most powerful (for thick material) is a high power and slow speed so the laser stays on the material longer and the weakest (light engraving) is low power and high speed.

Lasers cutters make cutting acrylic a breeze and streamline your processes. A laser cutter for acrylic makes it possible to quickly change designs, as well as produce the same design over and over with perfect results every time. Laser cutters are also easy to use, as they function as a printer.

In a C02 laser cutter, light is produced when electricity runs through a gas-filled tube with mirrors at both ends. ... These mirrors guide the laser beam into the material that is to be cut. The gas is typically a mixture of carbon dioxide, nitrogen, hydrogen, and helium.

You can use a laser machine to cut, engrave or mark many materials such as plastics, wood, rubber, leather, metals, textiles and many others.

An average PC uses 800VA, and the CO2 laser cutting machine uses 2480VA, while the CO2 laser engraving machine uses 2140VA. An estimation for each machine is as follows: CO2 Laser cutting machine uses 24.8p/hr and the CO2 Laser engraving machine uses 21.4p/hr.

For bare metals, fiber lasers represent the engraving method of choice. Fiber lasers are ideal for marking many types of aluminum, brass, copper, nickel-plated metals, stainless steel and more - as well as engineered plastics such as ABS, PEEK and polycarbonates.

Metals such as stainless steel and aluminum can be cut with a laser when compressed gas technology is used. ... Instead, the 40-watt laser is best used on acrylic or wood projects. However, it is also compatible with other materials: Leather.

Etchers and Engravers can get an average wage of Thirty Thousand One Hundred dollars per year. Etchers and Engravers receive the highest pay in Washington, where they earn an average job salary of close to $35860

You might find machines as cheap as $400 , but expect to pay $1,500 or more for a decent cutter, depending on mods and software upgrades you need to make

The best woods for laser cutting are Basswood, White Pine, Alder, Cherry, Oak, Baltic Birch Plywood, Balsa and Cork. Most laser cutters prefer soft woods that do not have a distorted, tight hard grain pattern. How well each species cuts depends on the power of your laser cutter along with thickness, and speed.

Plywood is perfectly made for being cut and engraved with a CO₂ laser system. The sheets must be fixed either on the cutter, nor is there a need to clean the working area from chips and dust after cutting.

40W laser can cut up to about 1/4" materials ranging from wood and acrylic down through lighter materials such as leather, fabric, foam, etc.

Laser processing of polystyrene can be performed with a 10.6 or 9.3 micron CO₂ laser. Laser cutting of polystyrene can be performed with a 9.3 or 10.6 micron CO₂ laser, resulting a clean, smooth, slightly melted cut edge, free of discoloration.

Cast acrylic can be cut with a laser, but it will not result in flame-polished edges. ... Extruded acrylic will cut cleanly and smoothly and will have a flame-polished edge when laser cut. But when it is engraved, instead of a frosted look you will have a clear engraving.

Cut width can be extremely small with laser cutting, less than 0.001 inch, and dimensional accuracy is extremely precise, at about ± 0.0005 inch. This accuracy is very useful for producing the jagged teeth used in some cutting tools.

While there are some laser cutters that can cut material as thick as 20 mm, most machines work on materials closer to 0.5-12 mm thick, depending on what's being cut. If you want to cut wood thicker than 20 mm, it's best to consider using a CNC router

A 100W laser cutter can cut and etch into 19mm Pine, 20mm Acrylic, 9mm Ply, MDF, Leather, Fabric, and Cardboard.

• Laser cutting demands high power consumption as compared to other techniques.
• The laser beam is very delicate to handle. A slight mistake while adjusting the distance and temperature can lead to burning or discoloring of the metal.
• The laser beam is harmful if it comes in contact with human workers. It can cause severe burns if it happens accidentally.
• Laser cutting is still not capable of cutting thick metals.
• The production is not consistent in laser cutting as the time for cutting various metals may vary.
• It does not compliment all types of metals.

The advantages of laser cutting are flexibility, precision, repeatability, speed, cost-effectiveness, great quality, contactless cutting, versatility and automation possibilities.

It plays an important role in, medicine, industry, and entertainment has resulted in fiber-optic communication, CDs, CD-ROMs, and DVDs. Without lasers there would be no supermarket bar code readers, certain life-saving cancer treatments, or precise navigation techniques for commercial aircraft

All metals are reflective to CO₂ laser beams, until a certain power density threshold value is reached. Aluminium is more reflective than C-Mn steel or stainless steel and has the potential to cause damage to the laser itself. Most laser cutting machines use a laser beam aligned normal to a flat sheet of material. This means that should the laser beam be reflected by the flat sheet it can be transmitted back through the beam delivery optics, and into the laser itself, potentially causing significant damage.

Laser cutting is a technology that uses a laser to cut materials and is typically used for industrial manufacturing applications, but is also starting to be used by schools, small businesses and hobbyists.  Industrial laser cutters are used to cut flat sheet material as well as structural and piping materials.

Laser cutting machine has high level of efficiency and required design replicas are exact copies of each other. Disadvantages of laser cutting: Efficiency and power consumption depends on the type of section that need to be carried out and nature of the laser. Usually, laser cutting have high energy consumption

However, the dust created by laser cutting is a serious inhalation hazard. The intense heat involved in the process creates particulates in the sub-micron size; the smaller the particulate, the easier it is inhaled and absorbed into the body.

In general, glass can be cut by applying a high-energy laser to melt it. Two other methods of cutting glass include engraving and etching. Laser cutting: Thin glass (when using specialized cooling processes) or stained glass can be cut at high Wattage (400 W)

The hazards associated with a laser cutter include the possibility of fires and the generation of hazardous and/or irritating combustion products. The laser cutter high powered laser can cause damage to eyes and skin, and it must be contained within the cutter.

Laser cutting works by directing the output of a high-power laser most commonly through optics. ... The focused laser beam is directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas, leaving an edge with a high-quality surface finish.
