Showing specs for: 20W
TL;DR
The 20W S30 Ultra is the balanced pick in the line: compressed beam cutting on thin wood, large community settings library, and the same stiff frame as the 22W refresh.
What this machine is for
Mid-range hobby diode laser focused on engraving and moderate cutting of organic materials.
Best for
Materials
Engraves
- · Wood
- · Leather
- · Slate
- · Anodized aluminum
- · Stainless (with spray)
Cuts
- · Basswood (up to 8 mm)
- · Dark acrylic (up to 5 mm)

Pros
- ✓Strong cut performance in the diode class
- ✓Sturdy frame reduces flex at higher speeds
- ✓Good value between Ortur and xTool
- ✓Wide accessory ecosystem (rotary, extension kits)
- ✓Active user base with tested settings
Cons
- ✗Open frame — full safety responsibility on you
- ✗USB-only on many configs (no Wi-Fi)
- ✗Support and documentation less polished than xTool
- ✗Still a diode — manage expectations vs. CO₂
- ✗Assembly and squaring require patience
Beginner notes
Choose the S30 Ultra over basic Ortur if cutting thin wood matters to you. For engraving-only projects, save money with a 10W model. Budget for air assist, honeycomb bed, and safety glasses.
Pro tips
Sculpfun publishes material test cards — use them. Multiple slow passes beat one fast pass for cut quality. Extension kits are useful but check frame rigidity before going oversized.
