A complete buying guide to 90W CO2 laser engravers, covering cutting and engraving performance, who should (and shouldn't) upgrade to 90W, key hardware features to prioritize, and a comparison of OMTech's Pronto 40 and Maker AF2028-80 models to help readers decide which machine fits their workspace and production needs.
This guide walks first-time buyers through the four most important factors to consider before purchasing a laser engraver: matching the laser type (diode, CO2, fiber, or UV) to your target materials, choosing the right wattage, confirming LightBurn software compatibility, and prioritizing safety accessories like enclosures and air assist. It includes power comparison charts and an expanded look at why LightBurn compatibility matters long-term.
A detailed breakdown of practical and maximum laser engraving depths across wood, acrylic, metal, and stone, covering the physics behind why depth varies by material, deep metal engraving with fiber lasers, deep 3D relief carving with CO2 lasers, the four physical limits that cap engraving depth, and when a CNC mill is the better tool for the job.
