Acmer P1 S Pro review: a rigid budget laser from $199
An all-metal open-frame diode laser from 6 W ($199) to 48 W, with a 380 × 370 mm bed and Wi-Fi. John’s Tech Blog called the 6 W the best budget laser; the lens isn’t user-replaceable.

Our verdict
The P1 S Pro is a sturdy budget laser. John’s Tech Blog found the 6W rigid, accurate and easy to get going, and it cut 3 mm birch well. Higher-power versions (10–48W) add cutting ability, but best-lasercutter.com warns of possible quality-control issues on the 20W module and a lens you can’t replace yourself. Buy the 6W or 10W as a cheap engraver.
What we like
- From $199 (6W)
- Rigid frame of 3 mm aluminium plates with four wheels per side
- Fine 0.06 × 0.08 mm spot on the 6W
- Limit switches on both axes; Wi-Fi app control
- Cut 3 mm birch well on the 6W (John’s Tech Blog)
What could be better
- Lens is not user-replaceable
- Possible quality-control issues on the 20W module (best-lasercutter.com)
- Open frame, Class 4: needs goggles and ventilation
- Minimal cable management; fiddly head connector
- Assembly took 45 minutes and a stripped screw in one test

What is it?
The P1 S Pro is Acmer’s budget open-frame laser. Its frame uses 3 mm aluminium plates and is sold with laser modules from 6W to 48W.
On 31 October 2026 prices start at $199 (6W), with 10W at $229, 20W at $329, 36W at $599 and 48W at $799.
Hands-on
John’s Tech Blog tested the 6W in April 2024:
- Assembly was advertised at 25 minutes but took just over 45, and one motor screw stripped and had to be replaced.
- The frame is rigid, with four wheels on each Y side and limit switches on both axes.
- A pine sign engraved at 50 mm/s and 75% looked good, with the grain showing through.
- 3 mm birch cut well; Acmer’s claim of 4 mm in one pass seemed believable.
- The first burn worked first time. The reviewer called it the best budget laser available.
Downsides noted: minimal cable management, a fiddly head connector and no protective lens cap, so keep the lens clean.
Higher-power versions
We found no detailed independent test of the 20W or larger modules. best-lasercutter.com scores the P1 S Pro 7.5/10, recommends the 6W and 10W for value, and warns that the lens isn’t user-replaceable and the 20W module may have quality-control issues. If you want to cut, the Acmer P2 33W is better proven.
Who should not buy it
- Anyone who wants an enclosed laser.
- Anyone planning business use: spare parts and the fixed lens are a risk.
vs rivals
- vs Creality CR-Laser Falcon 10W ($205): bigger 400 × 415 mm bed, similar price. See P1 S Pro vs CR-Laser Falcon 10W.
- vs Acmer P2 33W ($589): much more power, linear rails and air assist.
Final thoughts
The 6W P1 S Pro is a sturdy, cheap way to learn engraving. For serious cutting, skip the bigger modules and step up to the P2.
