Thunder Laser - Nova 35, 100W from [http://www.ThunderLaserUSA.com ThunderLaserUSA.com]
Bed size: 900mm x 600mm x 230mm (35.4” x 23.6”x 9.1”)
100 Watts of laser power from a CO2 laser at 10.64µ wavelength.
Cuts up to 3/4 inch material.
Materials which can be cut include:
*Thin Plywood
*Acrylic
*Paper, card stock, and poster board
*Vegetable tanned leather
*Craft foam
*Insulation board (the pink or green type with fire retardant)
Most of those can also be etched, meaning an image is burned into the surface. Other materials can be etched, but not cut, like glass, ceramics, or painted metal.
Materials which ''can not be cut'' include:
*Vinyl (including PVC, fake leather, Naugahyde, "Moleskin" notebooks, etc.) Watch this to see how to test for it: https://www.youtube.com/watch?v=ZqIU8yAobkc
*Poly-carbonate (it cuts but then melts back together or turns black)
*Metal (It can burn off the protective paint or anodized color, but the metal will not be affected.)

Laser Cutter and Engraver

Thunder Laser

Thunder Laser - Nova 35, 100W from ThunderLaserUSA.com

Bed size: 900mm x 600mm x 230mm (35.4” x 23.6”x 9.1”)

100 Watts of laser power from a CO2 laser at 10.64µ wavelength.

Cuts up to 3/4 inch material.





Materials which can be cut include:

  • Thin Plywood
  • Acrylic
  • Paper, card stock, and poster board
  • Vegetable tanned leather
  • Craft foam
  • Insulation board (the pink or green type with fire retardant)

Most of those can also be etched, meaning an image is burned into the surface. Other materials can be etched, but not cut, like glass, ceramics, or painted metal.

Materials which can not be cut include:

  • Poly-carbonate (it cuts but then melts back together or turns black)
  • Metal (It can burn off the protective paint or anodized color, but the metal will not be affected.)
  • Latex
  • Styrene, styrofoam, (They tend to catch fire, and they also produce lots of sooty residue)

Also, some other materials produce excessive soot, smoke, or fine threads of molten plastic that can clog the exhaust system. The fan is very hard to clean. Please be aware of what your cut is producing!

Chart of Speeds and Power (Starting point settings. Materials vary, and the laser is weaker than when it was new. Lower speed or higher power will be needed.)

We have a rotary device for engraving mugs, glasses, water bottles, and other cylindrical things. It is the RotoBoss Jr. For instructions, see this document.

Access and Training

To coordinate users who want to use the Thunderlaser, we have a sign-up sheet online. Reserve your time there. If nobody is signed up and you come to use it, it is first-come, first served, but often members will let you do a quick cut. If you go to the sheet and the dates are wrong, simply change the stat date at the top and all the other dates will update. Use Monday as the first day so the chart runs until next Sunday. But be sure to delete old reservations from the previous week.

Access to the Laser Cutter requires training from a qualified member.
