Alex Troyer 1.1 20 While CO2 laser cutters can cut a variety of materials, we stock sheets of Acrylic and Birch Plywood in 12x24 inch sizes, and 1/8" and 1/4" thicknesses. Keep in mind these dimensions are nominal, and may not be precisely accurate.

Zaara Hashmy 2.4 25
Zaara Hashmy 2.6 26 [[Waterjet cutting>>https://en.wikipedia.org/wiki/Water_jet_cutter]] is the process of using a high pressure jet of water to cut a material.  --laser to vaporize a material, so that the laser beam cuts through the material. When this is combined with a CNC tool head and both power and speed are balanced properly, this process allows the user to create flat parts from sheets of material, using 2D CAD drawings.--
Alex Troyer 1.1 27
Zaara Hashmy 2.12 28 The waterjet has a hydraulic power output of 820 W. There are a variety of materials that the waterjet can cut, example of allowed materials include acrylic, agate, aluminum, borosilicate, brass, carbon fiber, ceramic tile, copper, gabbro, fused glass, graphite, granite, HDPE, marble, memory foam, mild steel, neoprene, polycarbonate, polyethylene, polyurethane, porcelain tile, silicone, spring steel, stained glass, stainless steel, titanium, and tool steel. Materials that are water soluble or shatter under high pressure are not suitable for waterjet cutting.

Zaara Hashmy 2.14 30 **Advantages: (Needs to be edited still)**
Alex Troyer 1.1 31
32 * Laser cutting tool heads never touch the material, leave fairly clean cuts, and are highly accurate and repeatable.
33 * Laser cutting is far faster than manual cutting of the material, especially with repeated cuts in bulk materials.
34 * Laser cutting allows for very small and intricate designs, which would be difficult or impossible with traditional cutting tools.
35 * Laser cutting allows for much more efficient material usage than hand cutting in many cases.
36
Zaara Hashmy 2.14 37 **Disadvantages: (needs to be edited still) **
Alex Troyer 1.1 38
39 * Our CO2 lasers can't cut metals, or materials that reflect/poorly absorb its wavelength at powers below 130W.
40 * Laser cutters create a fine cutting spot size by focusing the laser through a lens, and as a result, cuts can never be completely perpendicular to the material.
41 * In most cases, CO2 lasers have difficulty penetrating cleanly through materials greater than 1/4 inch thick.

Zaara Hashmy 2.14 68 == OMTech Laser Settings (Long Focal Lens) (needs editing) ==
Alex Troyer 1.1 69
70 The Long focal length lens in our large-format OMTech laser cutter allows for more efficient cuts in thicker materials. However, this comes at the cost of a slightly large spot size, and thus, less fine engraving abilities.
71
72 Use the table below to input the correct values for your material. Note that for engraving, the thickness does not matter, because it won't cut all the way through. We also have sample engravings at various settings in the RPS if you would like to change the depth or darkness of the engraving. Keep in mind that the depth and color might not be exact, as they depend highly on laser focus and various other environmental parameters that cannot be controlled.

149 **Required PPE** for woods and acrylic:
150
151 * None
152
153 Once the job has concluded, allow the fumes to be vented for a minimum of 10 seconds. Please note that woods will have charring which is not harmful but may transfer to your hands or anything else it touches. If desired, you may sand the wood with the sandpaper we have in stock or use a sander. For acrylic sheets, peel off the protective film once ready for personal/project use.
154
155 **Required PPE** for rubber:
156
157 * Latex or Nitrile gloves

160
161 Once the job has concluded, allow the fumes to be vented for a minimum of 30 seconds. Please note that rubber materials will char as well and it is best practice to wear gloves while handling them. Rinse the rubber cuts under water to wash off as much charred edges as possible.

163 If you need assistance, RPS staff are always present to help with advice! **Please ensure that you return hand tools to their proper locations, and turn off the machine once use is complete.**
