The current English Form 4L page and Form Studio comparison give a 353 × 196 × 350 mm envelope; older comparisons show 355 mm Z. The pixel-size discrepancy is recorded beside that field.
Model notes · 01
Area exposure at larger scale
The LFD engine exposes a layer through an LCD mask using a 145-LED backlight and collimating optics. The product page describes a 46 µm pixel pitch, an optical sampling dimension rather than an independently measured part tolerance.
Model notes · 02
Model and material scope
The product page describes prototyping, tooling and manufacturing uses with Formlabs resins and Open Material Mode. Published example print times depend on the illustrated part and resin; they should not be applied to every full-height build.

Read this with the specifications
Manufacturer-stated build envelope. Supports, orientation and part shrinkage reduce achievable part dimensions. Medical uses require the specified validated material workflow.
A larger nominal envelope does not establish better print quality. Fit depends on the configuration, usable area, supports, and orientation.
