A complete guide to laser cutting cardboard: corrugated vs. non-corrugated types and thicknesses, why CO2 lasers are the top choice with OMTech machine recommendations at each level, cutting vs. engraving settings, popular project ideas from prototyping to architectural models, and essential fire-safety practices.

This guide explains line density (LPI/DPI/line interval) in laser engraving — how it works, why higher isn't always better, and how ideal settings vary by laser type (diode, CO2, fiber) and material (wood, acrylic, glass, metal). Includes benchmark charts, common mistakes, and practical tips like the defocus trick and material test matrices for dialing in clean, professional results.

Understanding the basics of laser speed settings is key to getting the best results. Read to learn what the variables on a laser engraving speed chart mean.
