2. Laser cutting - Wikipedia

   en.wikipedia.org/wiki/Laser_cutting

   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.

3. Model engineering - Wikipedia

   en.wikipedia.org/wiki/Model_engineering

   Increasingly, 'modern' technologies such as Computer aided design, cnc (computer numerical control) equipment, laser cutting, 3D printing and embedded systems are becoming part of the hobby as more and more of its practitioners have developed skills and familiarity with these techniques through their work, whilst younger people familiar with ...

4. CNC router - Wikipedia

   en.wikipedia.org/wiki/CNC_router

   The CNC Router is ideal for hobbies, engineering prototyping, product development, art, and production works. The CNC works on the Cartesian coordinate system (X, Y, Z) for 3D motion control; however, typical CNC operated systems can only make carvings on flat planes. The machine sits on a track and is not capable of making round or spherical cuts.

5. Maker culture - Wikipedia

   en.wikipedia.org/wiki/Maker_culture

   laser cutting, CNC milling, and knitting machines. To create one's own designs for digital fabrication requires digital design tools, like Solidworks, Autodesk, and Rhinoceros 3D. More recently, less expensive or easier to use software has emerged. Free, open-source software such as FreeCAD can be extremely useful in the design process.

6. Laser engraving - Wikipedia

   en.wikipedia.org/wiki/Laser_engraving

   Laser engraving metal plates are manufactured with a finely polished metal, coated with an enamel paint made to be "burned off". At levels of 10 to 30 watts, excellent engravings are made as the enamel is removed quite cleanly. Much laser engraving is sold as exposed brass or silver-coated steel lettering on a black or dark-enamelled background.

7. Rapid prototyping - Wikipedia

   en.wikipedia.org/wiki/Rapid_prototyping

   A dramatic development which RP shares with related CNC areas is the freeware open-sourcing of high level applications which constitute an entire CAD-CAM toolchain. This has created a community of low res device manufacturers. Hobbyists have even made forays into more demanding laser-effected device designs. [19]
