What the Plus revision changed
The Plus revision updates optical-unit motion, heating and sensing. Its adaptive layer mode varies slicing thickness with geometry. The manufacturer’s relative speed claims depend on the job and material rather than describing a fixed throughput.
Part removal
The announcement pairs the revised printers with Build Platform 2, which uses a flexible surface for part release. Confirm the platform and resin workflow supplied with a particular used machine or bundle.

What changed
- Refined LFS hardware and material settings; Build Platform 2 added a flexible quick-release surface.
Read this with the specifications
Current support lists new Form 3+ units while supplies last through 2026, excluding AMER where new units are no longer offered. Era=current reflects that listing, not a claim of latest generation. Published maximum Z is 193 mm; removal above 185 mm requires tank removal.
A larger nominal envelope does not establish better print quality. Fit depends on the configuration, usable area, supports, and orientation.
