## Verdict

The T1 Pro is one of the fastest consumer printers you can buy, thanks to its delta design. Reviewers praised the hands free leveling and speed but measured it as loud, and parts get weaker at top speed. It suits fast PLA and PETG prototypes and tall round parts, not quiet rooms or nylon.

## Pros

- Extremely fast, up to 1,000 mm/s claimed
- Fully automatic leveling
- Tall 330 mm build height
- Klipper web interface and Wi-Fi
- Low price for its speed

## Cons

- Loud, 71 dB average measured by 3DPrint.com
- Round build area limits wide parts
- Weaker layer bonding at top speed
- Single filament only
- Clunky touchscreen menus (The Gadgeteer)

## Questions buyers ask

### What is a delta 3D printer?

A delta uses three vertical arms to move the nozzle over a fixed round bed. It allows very fast moves, but the build area is a cylinder, 260 mm wide on the T1 Pro.

### Is the Flsun T1 Pro loud?

Yes. 3DPrint.com measured 71 dB on average with peaks of 91 dB, and TechRadar called the fan very loud.

### Can it print ABS or nylon?

Flsun lists ABS, PA and PC, but there is no heated chamber. ABS warped for 3DPrint.com, which did not recommend it for nylon or PC.
