What is the Saturn 4 Ultra 16K build volume?

The nominal build volume is 211.68 × 118.37 × 220 mm. It is a resin printer, so supports and a raft reduce the practical usable area.

How is the 16K different from the Saturn 4 Ultra 12K?

The 16K has a different LCD and a slightly smaller XY plate than the 12K. Use the exact model's dimensions and slicer profile.

Can the Saturn 4 Ultra print a 200 mm long model?

It fits along X at 200 mm with 5.8 mm per side to spare at zero clearance, but not along the 118.37 mm Y axis. Rotate the model and check supports.

Do I need to hollow models for the Saturn 4 Ultra?

Not for small solid miniatures, but hollow large parts to save resin and control peel forces. Use 1.0–1.5 mm walls, add drain holes and check the interior before printing.

Can the Saturn 4 Ultra print functional parts?

Yes, with an engineering or tough resin, but resin is usually more brittle than FDM. Increase wall thickness around holes, threads and snap fits and test the load direction.

Printers/Resin

Elegoo Saturn 4 Ultra 16K build volume and fit check

The Saturn 4 Ultra 16K is a resin printer with a 211.68 × 118.37 × 220 mm build volume. The narrow 118.37 mm Y dimension is usually the limiting axis, so long models often need a quarter turn toward the 211.68 mm side. Supports, a raft and the lift path also consume space that a simple bounding-box check cannot see.

Model-specific limits

This is a resin process: models need supports, a raft and drain holes. A solid model that fits the envelope may still be impractical or wasteful.
The 118.37 mm Y axis is much narrower than X. Rotate long parts before deciding that the model is too large.
The 220 mm Z height is shared with the lift mechanism and resin level; very tall parts need a stable support plan and slower lift speeds.

What fits

Miniatures and tabletop models

The high-resolution plate is well suited to small figures and multipart miniatures. Split large figures at natural joints.

Jewelry and small masters

Small, detailed masters fit comfortably, but hollow them and add drain paths before exporting for supports.

Dental and model work

The wide X axis suits dental models and small functional prototypes that need a smooth surface finish.

Orientation tips

Place the longest model dimension along the 211.68 mm X axis; a quarter turn is often enough to fit.
Add 5 mm of XY clearance for a raft and supports, and check the support plan rather than relying on the raw bounding box.
Hollow thick parts, add drain holes and verify wall thickness before printing; the fit checker does not model resin drainage.
