Materials Guide

Not all surfaces are created equal. The 1064nm Infrared laser interacts with the atomic structure of materials in ways that the 455nm Blue laser cannot.

IR Beam Interaction

Select a material to see how the IR laser energy is absorbed, reflected, or transmitted. The "heat" particles show the depth of interaction.

Stainless Steel Excellent

High absorption at 1064nm. Ideal for color marking and deep engraving. Low thermal conductivity keeps heat localized.

IR Absorption (1064nm)
Reflectivity (Danger to Lens)
Thermal Conductivity
Safety Tip: Clear acrylic and glass are invisible to 1064nm IR. The beam passes straight through and can damage your laser bed or surrounding objects.

Comparison

IR vs. Blue Diode

Laser Type Wavelength Best For... Worst For...
Infrared (IR) 1064nm All metals (Gold, Silver, Brass, Steel), hard plastics, opaque acrylic. Clear glass, clear acrylic, wood, transparent materials.
Blue Diode 455nm Wood, leather, dark acrylic, coated metals (Anodized Aluminum). Bare reflective metals (Gold, Silver, Copper), clear glass.
