TL;DR
TwoTrees does not sell a TTS-55 40W: the TTS-55 Pro ships with a 5.5W module, and TwoTrees' store lists 10W and 20W upgrade modules for the TTS family, no 40W. This profile covers listings that pair the frame with a 40W module from another source. Treat it as an unofficial configuration and confirm the module's maker, optical rating and warranty.

What makes this machine stand out
Hardware and workflow features worth understanding before you buy : not just wattage on a label.
Fastest TTS-55 setup
~12–18 min for a 10 × 10 cm photo and ~6–10 min for a 3 mm basswood square in our benchmark.
Basswood up to 10 mm
The deepest cutting of the TTS-55 tiers in our profile, with air assist recommended.
Our verdict
Ideal if you
TwoTrees TTS-55 40W targets mixed engraving and wood-cutting weeks: fewer passes on basswood and dark acrylic than weaker SKUs in the same line.
Skip if you
Wrong pick if you never engrave and only wanted the lowest price. Ultra-fine photo work can look better on an engraving-first SKU. Open-frame: safety and smoke are on you.
Pros
- Shortest times of the TTS-55 line in our benchmark: ~12–18 min for a 10 × 10 cm photo, ~6–10 min for a 3 mm basswood square
- Basswood up to 10 mm in our profile
- Fill speeds of 45–110 mm/s, several times the 10W module's
Cons
- TwoTrees' own store does not list a 40W module for the TTS family: confirm the module's maker, optical rating and warranty
- At $349–499 it overlaps with newer, faster 400 mm-class machines
- Widest spot of the line (~0.10 mm) and more smoke on an open 300 × 300 mm frame
What this machine is for
Maximum cut speed and depth in the line: engraving remains strong at tuned speeds

Practical notes
Beginner notes
This profile covers an unofficial 40W configuration: TwoTrees sells 10W and 20W modules for the TTS-55, not 40W. Read the FAQ below, then compare the 10W and 20W profiles via the chips before buying.
Pro tips
Treat engraving and cutting as separate profiles. Push cut speeds only after test squares on your material. Compare CO₂ only when clear acrylic or all-day production enters the picture.

Common questions
Who makes the 40W module on a TTS-55?
Check the listing carefully. In October 2026 TwoTrees' own store offered 20W modules for the TTS family but no 40W module, so 40W TTS-55 listings may combine the frame with a third-party or older module. Ask for the optical rating (not electrical input) and who provides warranty.
What does the 40W gain over the 20W on this frame?
In our benchmark, photo fills drop from ~18–28 min to ~12–18 min and the 3 mm basswood square from ~9–15 min to ~6–10 min. Our profile raises the basswood limit from 8 to 10 mm. The frame's 200 mm/s ceiling limits gains on large engravings.
Is a TTS-55 40W a sensible purchase in 2026?
Only at the bottom of its $349–499 range. At that money, newer 20–40W machines with larger beds, air assist and current support are available. It makes most sense if you already own TTS-55 accessories or need a compact 300 × 300 mm footprint.

Sculpfun · Diode · $270
Sculpfun S10 10W (2022) is a mid-size open-frame engraver with a sturdier industrial frame than S9, ~385 mm work area, and detachable laser cover. Positioned between budget S9 and S30 families for makers who want better rigidity without Ultra pricing.
Atomstack · Diode · $459 – $1,119
AtomStack A24 Pro is a 24W diode engraver and cutter (four 6W diodes) built on a unibody frame you set up in minutes. The 360 × 280 mm bed is small for this power class, but the optional conveyor stretches it to 360 × 800 mm. Diode only: for metal marking, Atomstack sells a separate A24 Pro 1064nm fiber version.
Sculpfun · Diode · $299 – $499
The iCube Ultra is Sculpfun's enclosed compact laser: a 12W diode in a Class 1 box with door interlock, emergency stop, temperature sensor, auto-focus and a built-in carbon smoke filter, over a 150 × 150 mm bed. The Dual version adds a 1.2W 1064 nm infrared module for bare metal and plastics. Sculpfun claims 10 mm paulownia in one pass; an independent review cut 3 mm and 5 mm plywood cleanly at slow speed. Small bed and no honeycomb are the trade-offs.
