Questions people ask
Which type of laser should a beginner buy?
TechRadar's table says diode lasers suit wood, paper, leather, cardboard, fabric, dark acrylic and stone. CO2 adds clear acrylic and glass, and fiber is the type for metal, plastic and stone. For a first machine, TechRadar names the Wainlux K10 on a budget and the Two Trees TS2 for beginners.
Do I need safety glasses for a laser engraver?
Check your machine first. Tom's Hardware says the xTool F1 is a Class 1 laser with the lid down, safe to operate around kids and pets, but it ships without glasses, and that the F2 Ultra is a Class 4 laser that demands proper safety practices. xTool's support page says to wear laser safety glasses whenever there's any chance of exposure to laser radiation, and that your laser's wavelength is what tells you the right lens. So use the goggles your machine's maker specifies for its wavelength.
Do laser engravers need ventilation?
Yes, plan for smoke. TechRadar says the open-frame Two Trees TS2 needs plenty of space and a well-ventilated area, and calls the Glowforge Pro's air filter a must-have for indoor use. Tom's Hardware says the xTool F2 Ultra requires a substantial air filtration system.
