Pros & Cons
Atomstack Proxima Fiber
What we like
- 20W MOPA fiber for deep, precise metal marking
- Very fast galvo scanning head
- Enclosed for eye safety
- Competitive price for a fiber laser
- Excellent for jewelry and industrial marking
Watch out for
- Cannot process wood or acrylic
- Small 200×200mm work area
- No rotary support
- Steep learning curve for new users
xTool F1 Ultra 20W Fiber + Diode
What we like
- Dual galvo lasers: fiber for metals, diode for wood/acrylic/leather
- Exceptional 10,000 mm/s galvo speed for mass production
- 16MP smart camera for auto-tracing and precise placement
- Marks bare metal, stainless steel, gold, silver, and aluminum
- Compact and enclosed — safe for studio or office use
- Expandable to 220×500mm with optional conveyor
Watch out for
- Premium price (~$2,999+)
- Small 220×220mm base work area
- Cannot cut thick materials (galvo lasers excel at marking/engraving)
- Steep learning curve vs gantry lasers
