2025 flagship Sculpfun diode — 70W class on the S40/S70 large frame
Last updated How we evaluate
Released October 2025
What this machine is for
Top-tier Sculpfun large-format cutting with maximum diode power
Reference benchmark same job size on every machine so you can compare times fairly.
Laser spot size
Compressed beam (fine spot)
Smaller spot = finer detail (frame motion is usually the same across tiers)
Motion precision: 0.1 mm repositioning
Sample engrave job
~5–8 min
Filled photo or logo on birch plywood
10 × 10 cm (4 × 4 in)
Sample cut job
~2–4 min
Simple square cut-out from 3 mm basswood
10 × 10 cm (4 × 4 in)
Times are estimates for the reference job above; your design complexity and settings will change them.
TL;DR
Sculpfun's S70 MAX pushes the S-series frame to ~70W optical class for shops that want maximum diode cutting depth without CO₂. Same oversized bed philosophy as S40 MAX — premium pricing and workshop space requirements apply.
What this machine is for
2025 maximum-power Sculpfun for large-format cutting and high-throughput engraving.

Beginner notes
Compare Atomstack A70 Max and Acmer P3 before buying — similar power class, different software and community.
Pro tips
If you don't need 70W daily, S40 MAX at 48W often offers better value per watt.
