TechRadar Review Calls Flsun T1 Fast and Accurate, With Single-Filament Limits

The T1 arrived essentially flat-packed, and the reviewer spent about an hour building it. The review says assembly was less difficult than expected because most complicated mechanical elements arrive pre-assembled, with builders mainly fitting panels, securing components and installing the top. Even so, the machine must be tightened correctly: after initial prints showed minor surface imperfections, checking the mechanism again and tightening a grub screw around the suspended print head immediately improved print quality. The review advises double-checking screws after the first few runs.

The printer uses a Delta mechanism rather than the Cartesian or CoreXY designs common among desktop 3D printers. Its print head hangs between three articulated arms above a circular build platform. Flsun quotes a maximum print speed of 1,000mm/s and acceleration of 30,000mm/s². The review says high-powered cooling and a fast-flow nozzle help maintain that pace, and standard E3D nozzle compatibility is a plus. The machine is single-filament only.

TechRadar lists exceptional print accuracy, extremely fast printing and excellent build volume as advantages. It lists very loud cooling, assembly that requires care and single-filament-only operation as drawbacks. The review says the most surprising result was not speed but the dimensional accuracy achieved after careful assembly and adjustment, which it describes as some of the best it has seen from a machine at this price level.

In design terms, the T1 has an enclosed heated chamber and an internal filament spool holder. The spool is suspended from a metal rod above the print head, an arrangement the reviewer calls crude but effective throughout testing. The machine measures 436 x 490mm in footprint and stands 836mm tall, requiring vertical space. The review notes that Prusa Research is one of the few other mainstream companies still producing a Delta-style printer, but that model is aimed at the professional market with a matching price.

The review concludes that the T1 involves compromises in noise, single-filament printing and setup. It says the machine is unlikely to be the best choice for every buyer unless speed is the main goal, but that rapid prototyping and functional printing are areas where it offers plenty to like.

Editor's Summary

TechRadar's review presents the Flsun T1 as a Delta-style 3D printer that is exceptionally fast and dimensionally accurate, with an enclosed heated chamber and strong build volume. Its main trade-offs are very loud cooling, single-filament-only printing, and assembly that requires careful tightening. The review positions it as a strong option for rapid prototyping and functional printing, provided speed and accuracy matter more than quiet operation or multi-material capability.
