xTool S1 40W
$2,499
approximate street price 
The xTool S1 40W is the high-power variant of xTool's flagship enclosed diode laser. Using eight 5.5W laser diodes fused into a 0.08×0.10mm spot, it cuts 18mm cherry wood and 15mm dark acrylic in a single pass — and can even score 0.1mm stainless steel, something few diodes manage. It shares the S1 20W's full enclosure, autofocus, built-in camera, and sliding front door, making it Class 1 safe out of the box.

Pros & Cons
What we like
- Cuts 18mm wood and 15mm acrylic in one pass
- Can mark and score thin stainless steel
- Full Class 1 enclosure — no safety glasses required
- Built-in camera for precise placement
- Autofocus and air assist included
- Same fast 36,000 mm/min (600 mm/s) speed as 20W
Watch out for
- Significantly pricier than the 20W variant
- Heavier than open-frame equivalents
- Enclosure limits maximum material height
- Diode still falls short of CO₂ for thick acrylic or glass
