Flsun T1 Delta 3D Printer Review: High-Speed Functional Printing With Loud Operation
TechRadar reviewer Alastair Jennings tested the enclosed Flsun T1 Delta 3D printer across PLA, PETG, ABS, and ASA materials, scoring it 4.5 out of 5 overall and 29 out of 30 on print-quality benchmarks. After about an hour of assembly and tightening a loose grub screw on the print head, the author reported fast printing (quoted up to 1,000mm/s) and high dimensional accuracy across its 260 x 330mm cylindrical build volume. It is recommended for makers, engineers, and workshops prioritizing rapid functional prototyping, though drawbacks include a very loud cooling fan, single-filament limitations, and a brass nozzle unsuited for abrasive materials.

AI brief
From the source report
The TechRadar Pro review says the FLSUN T1 combined high printing speed with accurate results after careful assembly and adjustment, making it worth considering if rapid prototyping or functional parts are priorities. Its loud cooling system, single-filament setup, and hands-on setup process may be drawbacks if you need quiet operation, multicolor printing, or a plug-and-play printer.
Best suited for Product designers, engineers, makers, and small workshops focused on rapid prototyping or functional components.
Highlights
The reviewer measured average X/Y dimensional error of 0.133 mm and reports CAD-designed parts fit together with little need for dimensional adjustment, a useful combination for functional printing.
The Delta printer is specified for speeds up to 1,000 mm/s and a 330 mm Z height, which may suit buyers prioritizing fast prints and taller parts.
The reviewer successfully printed PLA, PETG, ABS, and ASA, offering options beyond basic PLA.
Before you buy
The reviewer found the high-pressure cooling system extremely loud, even with a recommended silencer.
The T1 is a single-filament printer without a straightforward automatic multifilament system.
Assembly and careful checks matter: the reviewer says tightening a grub screw improved print quality after initial prints showed surface imperfections.
The review says the supplied 0.4 mm brass nozzle is not advisable for abrasive materials.
