What materials can the FLSUN S1 print?

The 350°C all-metal hotend covers PLA, ABS, PETG and PPS-CF, so it handles common filaments plus some engineering grades. High-temperature materials still need good ventilation or an enclosure.

How fast does it actually print?

FLSUN rates it up to 1200 mm/s with 40,000 mm/s² acceleration. Real prints usually run slower, since small parts and fine detail need lower speeds to keep quality.

Does it level itself?

Yes. It has auto-leveling plus Microtac radar control that checks the first layer. You still need to set the Z offset correctly for a clean start.

Can I monitor prints remotely?

The built-in AI camera lets you watch status and start prints remotely, and it records time-lapse video. Remote features need the printer connected to your network.

Is it good for beginners?

It can be, but a delta printer needs more calibration care than a simple bed-slinger. Beginners should expect a learning curve before prints come out reliably.

How much space does it need?

The frame measures about 21.6 by 23.4 by 40.5 inches, so it is tall. Leave clearance above and around it for the arms to move and for filament access.

Our take on the Flsun S1 Delta 3D Printer

The FLSUN S1 is a large-format delta 3D printer with a 350°C all-metal hotend, a built-in AI camera and a claimed top speed of 1200 mm/s with 40,000 mm/s² acceleration. Its delta frame, auto-leveling and radar-based first-layer control aim to make tall, fast prints repeatable, and it runs ABS, PLA, PETG and PPS-CF. It suits hobbyists and small shops that want speed and a tall build volume in one machine. Against bed-slinger rivals it trades a moving bed for a stationary delta gantry, which helps tall parts but makes the tall frame harder to enclose and place.

Pros

350°C all-metal hotend handles ABS, PETG and PPS-CF
Very high claimed speed and acceleration
Delta gantry keeps the bed stationary for tall parts
Auto-leveling and radar first-layer control
Built-in AI camera with remote start and time-lapse
Quiet operation rated at 55 dB or less

Cons

Tall delta frame takes up vertical space and is awkward to enclose
Delta calibration and tuning can frustrate first-time users
High speeds rarely hold on complex or small parts
Camera and app features depend on a stable network connection
