How does waterjet cutting work?

A waterjet cutter is a tool capable of slicing into metal or other materials using a jet of water at high velocity and pressure, or a mixture of water and an abrasive substance. The process is essentially the same as water erosion found in nature but accelerated and concentrated by orders of magnitude. It is often used during fabrication or manufacture of parts for machinery and other devices. It has found applications in a diverse number of industries from mining to aerospace where it is used for operations such as cutting, shaping, carving, and reaming.

How does laser cutting work?

In laser machining, a computer directs a high power laser to cut out the desired shape from stock material. The laser burns away or vaporizes the material, leaving the desired shape behind.

Here are some parts made using laser machining from clear acrylic plastic:

What is the kerf diameter of parts created by Big Blue Saw?

Kerf

Kerf is the cutting width of the tool used to make your parts. Features smaller than this size may be lost. Also, inside corners have to be able to accommodate the width of the nozzle.

Please also read The FAQ on part quality.

Abrasive Waterjet

We typically cut parts with an abrasive waterjet with a nozzle width of 0.040 inches.

Laser

The kerf from the laser beam cut is approximately 0.06 inches.
