Spindle motor material compatibility, 450nm and 1064nm laser compatibility, real cutting capacities by wattage — and the materials you should never load, no matter which module you run.
From aerospace-grade non-ferrous metals to carbon fiber plates and high-speed PCB prototyping — engineered for vibration-free cutting with composite superstructures.
Tested spindle speeds, feed rates, stepdowns, and cooling methods across all supported materials to maintain 15–25 µm repeatability.

Laser Tree's lineup splits into two families by wavelength — 450nm blue diode modules (5W up to the high-power K60/X1 series) and 1064nm infrared modules (LT-R1, LT-R2). Because each wavelength interacts with materials differently, compatibility depends on the module and the operation — engraving or cutting.
Two wavelengths, two very different strengths.
Excellent for organic materials and dark/opaque surfaces.
⚠️ Glass, ceramics and clear/white acrylic need pre-coating (dark tempera paint, laser marking spray, or black vinyl tape) to absorb the beam.
Excels precisely where blue diodes fail — bare metals and specific plastics.
❌ Not compatible: clear glass, transparent acrylic, light-coloured organic woods — these don't absorb 1064nm efficiently.
1064nm IR modules (1W/2W) are for precision engraving and marking only — they cannot cut.
Cutting depends strictly on the optical wattage of the 450nm blue diode modules, with compressed spots and air assist on the high-power tier.
Low-power modules suit hobbyist and multi-pass work on thin materials; high-power (K-Series/X-Series) modules are built for industrial, thick-material cutting.
Regardless of the Laser Tree module in use, never cut or engrave these — toxic gases, fire hazards, or optical damage to the module.
