* '''CO2 Lasers''' — Best for cutting and engraving non-metals (wood, acrylic, leather, fabric, paper, anodized aluminum, and more).
** '''[[OMTech_80W_CO2_Laser|OMTech 80W CO2 Laser]]''' (Red/Black) — Primary workhorse machine; fully operational. 📄 [[OMTech_80W_CO2_Laser|Full Machine Wiki Guide →]]
** '''130W CO2 Laser''' — Larger 4ft x 3ft bed; currently awaiting electrical hookup.


== Desired Tools ==
* '''[[Noua_60W_MOPA_Fiber_Laser|Noua 60W MOPA Fiber Laser]]''' — For metal marking, engraving, and color marking on stainless steel, titanium, brass, and copper. Also works on ceramics and stone. ⚠️ Use portable fume extractor near machine. 📄 [[Noua_60W_MOPA_Fiber_Laser|Full Machine Wiki Guide →]]
 
* '''[[ComMarker_5W_UV_Laser|ComMarker Omni X 5W UV Laser]]''' — Ideal for engraving plastics, glass, and coated metals without heat damage. Great entry point for tumbler engraving with the R5 Rotary attachment. ⚠️ Use portable fume extractor near machine. 📄 [[ComMarker_5W_UV_Laser|Full Machine Wiki Guide →]]
 
* '''Diode Laser''' — Entry-level machine; good for light engraving on wood, leather, and some plastics. Lower power than CO2.

Laser Cutting & Engraving Area

⚠️ LASER SAFETY GLASSES REQUIRED WHEN MACHINE IS OPERATING ⚠️

⚠️ NEVER LEAVE LASER UNATTENDED WHILE RUNNING ⚠️

Laser Machines

  • CO2 Lasers — Best for cutting and engraving non-metals (wood, acrylic, leather, fabric, paper, anodized aluminum, and more).
  • Diode Laser — Entry-level machine; good for light engraving on wood, leather, and some plastics. Lower power than CO2.

Safety & Usage

Safety Equipment

  • Laser Safety Glasses — ⚠️ Required for Fiber Laser and UV Laser operation (if not using the green shield). Never look directly at the Fiber Laser beam without glasses. Tip: you can safely view your work through your phone camera while engraving.
  • Fiber Laser View Blocking Panels — Please use the panels located near the machine to protect others in the space from beam exposure.
  • Fire Blanket — Located on the East Wall next to the Red/Black 80W CO2 Laser.
  • First Aid Kit — Includes burn treatment supplies. Located near the bathroom inside the main makerspace room.
  • Gloves — Available for handling materials as needed.

General Safety Rules

  • NEVER leave the laser unattended while operating
  • Always wear appropriate laser safety glasses
  • Ensure exhaust/ventilation is running before starting
  • Keep fire extinguisher within reach
  • Know the location of the emergency stop button

Operating Procedures

  1. Complete mandatory training before use
  2. Sign in on the log sheet
  3. Verify ventilation is running
  4. Check material against approved list
  5. Set appropriate power/speed settings
  6. Stay present during entire operation
  7. Allow material to cool before removing
  8. Clean bed and remove scraps
  9. Sign out on log sheet

Material Safety — Approved Materials

🔴 CO2 Lasers (80W & 130W)

Material Cut Engrave Notes
Wood / Plywood Yes Yes Use air assist; watch for resin flare-ups
MDF Yes Yes Heavy smoke — ensure ventilation is running
Acrylic (Cast) Yes Yes Best results, clean cuts
Acrylic (Extruded) Yes Caution Tends to melt; less crisp engraving
Paper / Cardboard Yes Yes Low power; fire risk — monitor closely
Leather (Veg-tanned) Yes Yes NOT chrome-tanned leather
Cotton / Natural Fabrics Yes Yes Low power; watch for ignition
Cork Yes Yes Low power
Rubber (Laser-safe only) Yes Yes Only use laser-rated rubber
Anodized Aluminum No Yes Engraving only; bare aluminum requires fiber
Glass No Yes Engrave only; use with care
Slate / Stone No Yes Engrave only
Coated/Painted Metals No Yes Laser removes coating to mark surface

🔵 Diode Laser

Material Cut Engrave Notes
Wood / Plywood Yes (thin) Yes Works well on light woods; slower than CO2
Leather (Veg-tanned) Yes (thin) Yes NOT chrome-tanned leather
Paper / Cardboard Yes Yes Low power; fire risk
Acrylic (Dark/Black only) Limited Yes Clear/white acrylic does not absorb diode wavelength well
Anodized Aluminum No Yes Engraving only
Cotton / Natural Fabrics Yes (light) Yes Low power; watch for ignition

🟠 MOPA Fiber Laser (Noua 50W)

Material Mark/Engrave Notes
Stainless Steel Yes Excellent results; color marking possible
Titanium Yes Vivid color marking
Brass Yes Marking and engraving
Copper Yes Marking; higher power needed
Aluminum (bare) Yes Marking and engraving
Anodized Aluminum Yes Deep engraving through anodize layer
Gold / Silver Yes Jewelry marking
Ceramics Yes Surface marking
Stone / Slate Yes Surface marking
Coated/Painted Metals Yes Removes coating to expose metal

Note: The Fiber Laser is for metals and hard surfaces only. Do not attempt to use on wood, acrylic, fabric, or other organic materials.

🟣 UV Laser (ComMarker Omni X 5W)

Material Mark/Engrave Notes
Plastics (most types) Yes Excellent — marks without burning or melting
Glass Yes Clean surface marking
Coated/Painted Metals Yes Removes coating cleanly
Anodized Aluminum Yes Good results
Stainless Steel Yes Surface marking (lower contrast than fiber)
Ceramics Yes Surface marking
Wood Yes Light engraving; less ideal than CO2
Leather Yes Light marking
PCBs / Electronic Components Yes UV is well-suited for sensitive components

Note: The UV Laser excels at materials that are heat-sensitive or difficult to mark with CO2 or fiber. It is lower power (5W) — not suitable for cutting.

Material Safety — Prohibited Materials

Material Reason
PVC / Vinyl Releases chlorine gas — EXTREMELY DANGEROUS
ABS Plastic Toxic fumes, melts poorly
Polycarbonate (Lexan) Discolors, catches fire easily
HDPE / Polypropylene Melts, doesn't cut cleanly
Polystyrene / Styrofoam Catches fire, toxic fumes
Fiberglass Toxic fumes
Carbon Fiber Toxic fumes, fire risk
Chrome-tanned Leather Contains chromium — toxic when lasered
Coated / Treated Wood Unknown chemicals, toxic fumes
Any material of unknown composition Always verify material before lasering

Fire Safety

  • Keep a fire extinguisher (CO2 or ABC) within arm's reach
  • Fire blanket is located on the East Wall next to the Red/Black 80W CO2 Laser
  • If fire occurs: STOP laser, keep lid closed if small flame, use extinguisher if needed
  • Never use water on electrical fires

Emergency Procedures

  • Emergency stop button: Red/Black 80W CO2 Laser — E-Stop located near the LCD panel
  • Fire extinguisher: Left of the Red/Black 80W CO2 Laser
  • Fire suppression blanket: Left of the Red/Black 80W CO2 Laser, on the East Wall
  • First aid kit: Near the bathroom inside the main makerspace room
  • Emergency contact: Chris Kaminsky — 616-802-7088 — chris@grandrivermakerspace.org
  • In case of uncontrolled fire: Evacuate immediately and call 911
