About Laser Cutting
Laser cutting is one of the digital making methods available through Personal Factory. Laser cutting is a type of subtractive manufacturing that cuts a digital design file into a piece of sheet material. A computer directs a high-power laser at the material. The material then melts, burns or vaporizes leaving an edge with a high-quality finish.
Laser cutting produces part shapes by cutting sheet material using an intense laser beam. This cutting method uses a beam of high-density light energy focused through a tiny hole in a nozzle. When this beam strikes the surface of the workpiece, the material of the workpiece is vaporized.
Laser Advantages
The process offers low cost for prototypes and short runs since no physical tooling is needed. Heat distortion is minimal and typically limited to about 10% of material thickness. Cut parts generally remain flat. Lasers leave minimal burrs.
Shapes
Cutting with a laser can produce almost any 2D shape including cutouts for parts such as enclosures, cams, brackets, decorative items, holders, mechanisms, etc.
Materials
Several materials are applicable. Aluminium can be laser cut but requires a higher power more expensive laser. Stainless steel, plain steel and spring steel are highly suitable. Metals such as copper alloys are difficult due to their ability to reflect the laser light and absorb heat. Many plastics are problematic due to toxic fumes.
Design Considerations
Sharp inside corners of the part may have a slight rounding due to beam radius of approximately 0.02 – 0.04″. Edge burrs are usually minimal and deburring of edges is usually not necessary. Thin flimsy structures, such as shapes where a high percent of material is removed and long slots may experience some warping.
Custom Machining
