Rapid Prototyping Technology Rapid Prototyping is a 3-D printing process that produces a solid plastic model from a CAD file. It is benefical to companies because it reduces cost, and avoids delays. It is also highly accurate. Application of Lasers in Production Lasers are used for hands off welding. Pieces are fused by directing a concentrated beam of coherent light to a small spot.
Laser beams use a lower heat input, but higher intensity than an electron beam.
Some software packages today allow viewing through special helmets or glasses. There are also packages available that format video images to create a depth impression.
