Before you can use the laser, you must have taken the Laser Cutter Orientation. Classes are scheduled monthly. If you have not had the class yet, you are not authorized to use the laser under ANY circumstances!'

Specs[edit | edit source]

  • 90W CO2 Laser
  • Working area cutting: X=23.5"(596mm) Y=15.75"(400mm)
  • Work Area Engraving: X=21.5"(546mm) Y=13.75"(349mm)
  • Max material thickness .250"(6.5mm)

Training[edit | edit source]

See the Make717 Events website for upcoming laser orientation.

Training Documents[edit | edit source]

The following files are provided as a reference for members who have taken the orientation. They may be reviewed by anyone who contemplates taking the laser orientation. However, reading or downloading the files is not a substitute for taking the orientation. The most current version of these documents will be posted at the laser station in paper form.

Material Thickness Raster/Vector Power Speed Passes Description
Slate N/A Raster Engrave 25% 100% 1 Line art can be driven at higher power.
Glass N/A Raster Engrave 50% 100% 1 Line art can be driven at higher power.
Whiteboard Masonite N/A Raster Engrave 50% 100% 1 Smut cleans with alcohol.
Whiteboard Masonite 3/16" Vector Cut 100% 75% 2/3 If corners don't cut cleanly, use 3 passes.
Anodized Aluminum N/A Raster Engrave 10% 100% 1 Higher power burns out grayscales
Hardwood N/A Raster Engrave 25% 100% 1 Uneven due to grain of wood.
Hardwood .125" Vector Cut 50% 100% 2 Lots of smoke
Hardwood Veneer N/A Raster Engrave 10% 100% 1 N/A
Hardwood Veneer N/A Vector Cut 15% 100% 1 N/A
MDF .250" Vector Cut 100% 100% 7 Could probably lower power (keep speed up) and do more passes to cut down on charred edges.
Baltic Birch N/A Raster Engrave 25% 100% 1 Best contrast. Higher power leaves ash.
Baltic Birch 1.5mm Vector Cut 50% 100% 1 Increase power for thicker ply.
Baltic Birch .250" Vector Cut 100% 100% 1/2 Focus critical; may need 2 passes.
Basswood N/A Raster Engrave 25% 100% 1 Best contrast.
Basswood .125" Vector Cut 50% 100% 1 Fast speed/low power reduces chances of fire.
Balsa N/A Raster Engrave 10% 100% 1 Fuzzy surface makes for blurred outlines.
Balsa .125" Vector Cut 50% 100% 1 Fast speed/low power reduces chances of fire.
Acrylic N/A Raster Engrave 10% 100% 1 Higher power may cause warping.
Acrylic .125" Vector Cut 65% 100% 1 Honeycomb table causes crazing - use knife edge.

Paper - 20lb stock N/A Vector Cut .1% 100% 1 Use hold down clamps
Soapstone N/A Raster Engrave 50% 100% 1 Engraves unevenly. Oil surface to enhance contrast.

Approved Materials List[edit | edit source]

Note: Please make sure there are approved settings before using any approved materials. LAMA can help you establish settings for approved materials without settings.

Material Notes
Plywood Laser ply is required. Normal plywood is not laser compatible.
MDF & LaserMDF Dirty. Cleanup required. Use knife edge bed. Do not use honeycomb bed.
Wood Veneers
Cork
Paper
Acrylic
Styrene (sheet) Emits heavy smoke.
Brass, Bronze, Copper Lead-free alloys are preferred. Will not cut, but can be engraved with Cermark.
Steel Can be engraved.
Aluminum Anodized aluminum can be engraved. Mill finish cannot.
Slate Can be engraved.
Silicone (thin sheets) Anything else chars and doesn't cut.
White Delrin/Acetal Fire hazard.
Polypropylene It will cut up to about 2mm. Fire risk.
GPPS/Polystyrene/HIPS (thin sheets) NO FOAM (it's highly flammable)
Cloth/Felt/Cotton/Silk/Hemp
Non-chlorinated rubber
Leather
Depron foam The only approved foam for laser cutting.
Magnetic Sheet
Glass/Ceramic Engrave Only
Whiteboard/Blackboard Masonite

Prohibited Materials List[edit | edit source]

Material Notes
PVC PVC releases chlorine which combines with moisture in the air to create hydrochloric acid. The acid damages the laser and the ventilation system, and is hazardous if inhaled.
Plywood Normal plywood glue is incompatible with laser cutting. Can release formaldehyde
HDPE (milk cartons) Clogs the bed.
ABS Clogs the bed, emits cyanide.
Black Delrin/Acetal Contains black carbon which can be toxic.
Teflon Toxic.
Nylon
Polythene/polyethylene
Lexan/Polycarbonate Absorbs IR light, reducing laser efficiency. Yellows when cut.
Fibre glass Unknown resin, glass particles.
Carbon Fiber
Magnesium Magnesium fires are especially difficult to extinguish. Because of this hazard, magnesium cutting/etching is not permitted.
Asbestos laden materials Any process that releases asbestos is forbidden by Federal and state law.
