Flsun S1: Delta 3D printer
The S1 from Flsun is a new 3D printer that is advertised as being particularly fast. It has an unusual shape and, thanks to its closed design, is intended to be less harmful to the user's health, even when set up in a room not specifically designed for this purpose.

The Flsun S1 is quite an unusual 3D printer. Designed as a so-called delta printer, the print head of the Flsun S1 hangs on several belts and is controlled by shortening or lengthening these belts. The S1 is said to come with a very high speed that is specified as up to 1,200 mm/s, while the maximum acceleration is stated as 40,000 mm/s². The maximum flow rate for PLA filament is specified as 110 mm³ per second. As usual, compromises have to be made between maximum speed and accuracy. According to the manufacturer, printing accuracy is 0.1 millimeters, while a layer thickness of between 0.1 and 0.35 millimeters is recommended.

The Flsun S1 measures 550 x 595 x 1030 millimeters and weighs an impressive 39 kilograms, but the printing chamber is 320 millimeters in diameter and 430 millimeters high. The print nozzle can be heated to up to 350 °C and has a diameter of 0.4 millimeters. The print bed can be heated to up to 120 °C; according to the manufacturer, the use of PLA, PETG, TPU, ABS and carbon is supported. The print bed can be heated in zones. There is also a chamber for drying the filament on the top of the model. A LiDAR sensor system should ensure high accuracy of the first layer, while leveling and Z-axis compensation should be automatic. A camera is installed, so the AI should then be able to detect errors, which also enables time-lapse recordings to be made.

Operation is said to be particularly easy thanks to a touchscreen with a resolution of 1920 x 1080, which also supports a connection to a PC. The exhaust air from the FDM printer is not simply released into the environment; instead, a HEPA and an activated carbon filter are used. The model is listed directly by the manufacturer for a price of just under US$1300: the first batch of pre-sale activities has ended. Shipping for the second batch will start on Jan 31 for China, Feb 10 for US/RU and Feb 20 for EU/CA/AU/UK.
