Guides
Real shop experience meets physics. Comprehensive guides to help you understand how lasers work, what materials you can cut, and which machine to buy.
The Laser Test Lab
A five-stage handbook for dialing in laser settings on your own machine, in about 30 minutes with a few pieces of scrap. Saved for good, with the physics behind every mark.
- • Pick your mark: every mark your material can make, and why
- • Find the neighborhood, dial it in, settle the face-off
- • Grade by eye: which one looks darker, no tools
- • Physics-backed breakdowns for aluminum, steel, wood, acrylic
Why Lasers Work (The Physics Guide)
8-level deep-dive from workshop observations to quantum mechanics. Learn why CO2 lasers cut wood in one pass but diode lasers need 15.
- • Wavelength absorption explained with interactive tools
- • Molecular bonds and vibrational resonance
- • Why marketing specs lie about performance
- • Complete material compatibility matrix (48 materials)
Laser Material Compatibility Guide
Complete compatibility ratings for CO2, Fiber, Diode, and UV lasers across 48 materials. Shop reality + physics explanations.
- • 192 laser-material combinations tested
- • Safety warnings (PVC, ABS, chrome-tanned leather)
- • Quick decision guide for choosing laser type
- • Settings guidance for each material
Why These Guides Are Different
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:
- ✓ Start with real shop failures, not marketing promises
- ✓Explain the physics behind why materials work (or don't)
- ✓ Include total cost of ownership (ventilation, software, consumables)
- ✓ Give honest limitations alongside capabilities
- ✓ Save you from the expensive mistakes I made
More Guides Coming
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.
