Bubblegram. A laser glass sculpture of a caffeine molecule. A bubblegram (also known as laser crystal, Subsurface Laser Engraving, 3D crystal engraving or vitrography) is a solid block of glass or transparent plastic that has been exposed to laser beams to generate three-dimensional designs inside. The image is composed of many small points of ...
The laser is a drawing tool: the beam emitted from it allows the controller to trace patterns onto the surface. The controller determines the direction, intensity, speed of movement, and spread of the laser beam aimed at the surface. The surface is chosen to match the type of material the laser can act on.
Industrial laser cutting of steel with cutting instructions programmed through the CNC interface. The laser beam is generally focused using a high-quality lens on the work zone. The quality of the beam has a direct impact on the focused spot size. The narrowest part of the focused beam is generally less than 0.0125 inches (0.32 mm) in diameter.
Laser ablation or photoablation (also called laser blasting[1][2][3]) is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates. At high laser flux, the material is typically converted ...
The largest machine will produce letters from a 13 to 597 mm (0.5 to 23.5 in) high. Both the Cricut and Cricut Explore Air 2 require mats and blades which can be adjusted to cut through various types of paper, vinyl and other sheet products. The Cricut operates as a paper cutter based upon cutting parameters programmed into the machine, and ...
A typical 8.5 × 11 sheet of paper has 0.25-inch (6.4 mm) margins, reducing the printable area to 8.0 by 10.5 inches (200 mm × 270 mm), or 84 square inches. 84 sq/in × 90,000 dots per sq/in = 7,560,000 dots. 1 megabyte = 1,048,576 bytes, or 8,388,608 bits, which is just large enough to hold the entire page at 300 dpi, leaving about 100 ...
6. Upgrade Their Cage. Your birdie's cage should be a comfortable, clean, enriching, and spacious sanctuary that they can relax into after a long day. Spruce up their cage by deep cleaning it ...
Laser bonding is a marking technique that uses lasers to bond an additive marking substance to a substrate.. First invented in the mid 1990s by Essilor International, this patented method [1] produces permanent marks on metal, glass, ceramic and plastic parts for a diverse range of industrial and artistic applications, ranging from aerospace and medical to the awards and engraving industries.
