Choose the machine class that fits the work.

Recommendations are ranked by optical output, usable bed area, focal geometry, and the selected material profile.

Before buying: every tier needs enclosed operation, rated eye protection, and ducted exhaust. Never process PVC or vinyl. Read the safety reference

Reference data

Substrate benchmark matrix.

Use these values as starting points for setup, calibration, and process documentation. Actual results vary with density, coating, focus, optics, and machine condition.

Absorption values are normalized coefficients at the source wavelength. Kerf values assume a focused 2.0" lens.

Safety reference

Optics and airflow are part of the cut.

Optical power is only one variable. Focal geometry, airflow, enclosure design, and material composition determine whether a process is repeatable and safe.

CRITICAL WARNING

MATERIAL SAFETY GATE

Never process PVC, vinyl, unknown plastics, halogenated materials, or substrates with unidentified coatings. Toxic or corrosive gases may be produced.

1.5"ENGINE PICK

Short focal length for fine detail, small kerf, and thin materials. Offers a smaller working depth and requires tighter focus control.

RECOMMENDED FOR

Fine engraving
Thin sheet stock
Small-format detail

2.0"ENGINE PICK

General-purpose focal length for balanced spot size, working depth, and everyday cutting.

RECOMMENDED FOR

Plywood
Acrylic
General workshop use

4.0"ENGINE PICK

Longer focal length for thicker materials and greater working depth. Produces a larger spot and typically requires more power.

RECOMMENDED FOR

Thick stock
Deeper cuts
Applications where working depth is critical

Ventilation reference

Exhaust airflow targets by enclosure volume
Enclosure volume	Minimum target	Recommended target
Compact desktop	150 CFM	250 CFM
Medium workshop	250 CFM	400 CFM
Production enclosure	400 CFM	600+ CFM

EXHAUST CFM CALCULATION NOTES

Required CFM ≈ (Enclosure volume ft³ × Air changes per minute) × Duct loss factor

Convert enclosure size to cubic feet: L × W × H (mm) ÷ 28,317,000.
Laser enclosures need fast turnover; plan for at least 30 air changes per minute at the cutting zone.
Add 20–40% for duct length, elbows, filters, and inline carbon stages. Every 90° elbow costs roughly the resistance of 1.5–3 m of straight duct.
Keep the exhaust port near the cutting area and supply make-up air on the opposite side of the enclosure.
Use the larger of the calculated value and the table minimum.

Ventilation values are starting targets, not a substitute for local code compliance, enclosure testing, or manufacturer requirements.
