Questions about the L1S PRO

All questions

Does the L1S PRO have UV curing?

Yes. Every Pro model has UV curing, for liquid acrylic faces cured on the machine: the SG-S 3D PRO ULTRA, the L1S PRO and the SG-S 3D L2S PRO.

L1S PRO or L1S?

The L1S PRO is the L1S's Pro version: it adds UV curing. The catalogue pictures it on a closed cabinet, 1530 mm tall against 740 mm, with an integrated filament drier, and gives it the same returns, colours, recommended speed and file formats as the SG-S 3D L1S.

L1S PRO or L2S PRO?

Both have UV curing, and the catalogue gives both the same returns, beds, recommended speed and file formats, on the same kind of cabinet. The SG-S 3D L2S PRO prints four colours in one print; the L1S PRO prints three.

Can it run overnight?

Yes. It is built to run unattended. If the power drops it carries on where it left off, and it detects a broken filament.

Will it fit through my door?

With the 800 bed it is packed at 1380 × 1390 × 1640 mm, and with the 1200 bed at 1820 × 1790 × 1660 mm. Send us a photo of your doorway and we'll check.

How much is the L1S PRO?

Ask us for a price for the bed size you want, 800 × 800 or 1200 × 1200 mm, and we'll come back within 1 working day.
