• Users must exercise special caution when working with conductive materials as buildup of their dust and ambient
particles may damage electrical components, cause short circuits, or produce other effects including reflected laser
radiation.
This machine can be safely used with the following materials:
• Aluminium
• Brass
• Carbide
• Gold
• Silver
• Steel
• Stone, including Granite, Marble, etc.
• Titanium
• Tungsten
This machine can be used with some other metals, hard plastics, and other materials with some care. For other materials, if
you are unsure about its safety or laserability with this device, seek out its material safety data sheet (MSDS). Pay
especial attention to information about safety, toxicity, corrosiveness, reflectivity, and reaction(s) to high heat.
Alternatively, contact our support department for further guidance.
See §4.3 for the recommended parameters for the most commonly engraved materials.
This machine CANNOT be used with the following materials or with any materials which include them:
• Artificial Leather containing Hexavalent Chromium (Cr[VI]), due to its toxic fumes
• Astatine, due to its toxic fumes
• Beryllium Oxide, due to its toxic fumes
• Bromine, due to its toxic fumes
• Chlorine, including Polyvinyl Butyrale (PVB) and Polyvinyl Chloride (PVC, Vinyl, Cintra, etc.), due to its toxic fumes
• Fluorine, including Polytetrafluoroethylenes (Teflon, PTFE, etc.), due to its toxic fumes
• Iodine, due to its toxic fumes
• Paper and Paperboard, due to their high flammability when exposed to the concentrated laser
• Phenolic Resins, including various forms of Epoxy, due to their toxic fumes
• Wood, including MDF, Plywood, Balsa, Birch, Cherry, Oak, Poplar, etc., due to its high flammability
