FLSUN Super Racer(SR) 3D Printer Review

Have you always dreamed of a fast, efficient and easy to set up 3D printer? You don’t have to imagine it because it’s here now! The Flsun Super Racer (SR) 3D printer meets these three criteria and more. This revolutionary printer will amaze you with its many qualities.

The Design

Flsun Super Racer (SR) is one of the biggest delta printers. These printers usually don’t have the largest work surface, but they can offer a higher print height. With a diameter of 260 x 330 mm, it offers quite a large volume considering its mechanical location and price range. Delta printers are rare and usually twice as expensive with print volumes as the SR.
The Flsun Super Racer (SR) comes with a small touchscreen that can be attached to the printer frame with a magnet. You can download and move them; it stays attached to the SR by one of those elastic straps you can see on police car dashboards from the 1980s. At 3.5 inches, it’s not the biggest touch screen, but with the cable and the ability to move it around, it can come in handy for some.


The Flsun Super Racer (SR) is equipped with a Bowden extruder with two drives, which must allow stable and reliable thread flow to the hot end. Bowden-type extruders sometimes have issues with not blocking the flexible filament feed, but dual drives should address some of these issues as they allow an even feed. Yes indeed! No racer is 100% ready without a bit of carbon fiber, and in the Flsun Super Racer (SR) they can be found in the parallel arms that support the printheads. Carbon fiber is a very strong ultra-light material that should make already lightweight printheads lighter. With less mass to move, the high-speed operation becomes less susceptible to print artifacts.

Flsun would be silly to name the printer a “super racer” if it didn’t offer impressive print speeds. Flsun says the default SR print speed is 150mm/sec, but you can print up to 200mm/sec if you prefer. For comparison: Flsuns Q5 works at 30-100 mm / sec. What does this mean for print quality? In general, delta printers can print at higher speeds than “regular” Cartesian devices due to their mechanical layout and smaller mobile table.
The heated Flsun Super Racer (SR) platform puts together two unique properties: It is made of tempered glass and is portable. A textured surface is probably the best solution because it provides a strong bond without glue and easily allows the prints to peel off once cooled. It also allows for an aesthetic first layer. Once installed, the platform can heat up to 100°C, which is sufficient for most threads you would use in such a printer. It should also be mentioned that the platform has automatic leveling. That’s great – even less worried about shifting.

Since the Flsun Super Racer (SR) can achieve high printing speeds, it may be advisable to equip the engine with a hot-tipped volcano. This should allow for fast and efficient yarn melting and provide sufficient yarn yield for potentially high SR print speeds. Such hot tips also allow you to experiment with different nozzle sizes and flow rates so developers can be more creative and innovative in their 3D printing hobby.


Two other features should be briefly mentioned. The first is that this printer has a filament sensor and print resume function. This wonderful 3D printer can be yours for only $459 on Banggood.
