Real shop experience meets physics. Comprehensive guides to help you understand how lasers work, what materials you can cut, and which machine to buy.
8-level deep-dive from workshop observations to quantum mechanics. Learn why CO2 lasers cut wood in one pass but diode lasers need 15.
Complete compatibility ratings for CO2, Fiber, Diode, and UV lasers across 48 materials. Shop reality + physics explanations.
I've tested dozens of laser cutters in my shop and wasted hundreds of dollars learning what marketing departments won't tell you. These guides:
I'm working on additional guides covering 3D printers, CNC machines, and workshop integration. Each one follows the same approach: real testing, physics explanations, and honest assessments.
Looking back, I wish someone had told me about the chlorine gas from PVC before I lasered it. Or that CO2 lasers can't cut bare aluminum no matter what the marketing says. These guides are what I needed when I started.
