1. What materials can S1 print?

Low-temperature materials such as PLA, PETG, TPU, and support materials for PLA and PETG (supports PLA, PVA, HIPS, etc.).

Conventional high-temperature materials such as ABS, ASA, PC, PA, PA-CF/GF, PET-CF/GF, PPA-CF/GF, etc.


  1. What is the maximum hot end/heat bed temperature of S1?

The maximum hot end temperature is 350℃ and the maximum hot bed temperature is 120℃.


  3. What is the maximum print size of S1?

The maximum print size of S1 is 320*320*430mm³.


  1. Is the nozzle brass or hardened steel?

The printer comes pre-installed with a 0.4mm hardened steel nozzle.


  1. What does the hotend kit of S1 consist of?

The hotend kit of S1 consists of nozzle, throat, heating block, temperature sensor, heating ring, heat sink and silicone sleeve.


  1. Does the camera support remote monitoring?

Yes, there are two ways:

1). Add the printer to the slicing software through the printer's IP address;

2). If the computer and printer are in the same LAN, you can directly enter the printer's IP address on the computer for remote monitoring.


  1. How is the air filtration function implemented?

During the printing process, the cavity filtration function is turned on, and the cavity fan starts working, and the toxic gas is discharged from the outside of the cavity through the filtration system.


  1. Isthe nozzle easy to replace?

If the nozzle is replaced separately, it can be quickly disassembled, but if there is blockage inside the effector, it needs to be disassembled. We have corresponding disassembly videos and documents.


  1. How are time-lapse files stored? Will they be automatically deleted? Or will they be overwritten?

The S1 has enough storage space, so the time-lapse videos will be automatically saved, and users can choose to delete them. In addition, if the remaining 5% of the space is left, a pop-up window will remind users to clean up the memory.


  1. Does the drying box on the S1 have a sealing rubber ring?

It has a sealing rubber ring, and in addition, it is equipped with a drying box. If the humidity is relatively high where you live, the S1 is an excellent choice.


  1. How to level the bed?

Our printer supports automatic bed leveling. We recommend that you check the hot bed leveling option before starting a print job. If the first layer of the print is fine after leveling once, there is no need to repeat the leveling. There is no need to level the hot bed manually.


  1. How does flow calibration work?

By printing a predetermined model, comparing the theoretical feed amount and the actual feed amount, you can judge whether the extrusion system is normal.


  1. How to reduce the noise generated during S1 printing?
  2. Reduce the printing speed appropriately.
  3. Place a silencer at the air duct.

  1. What is Flsun Slicer? Can it be connected to other brands of printers? Can S1 support slicing software such as Orca?

Flsun Slicer is a new slicing software currently launched by our company. It is developed based on Prusa and has no plan to connect with other brands of printers for the time being. S1 supports Orca slicing software. After downloading, you need to add a configuration file.


  1. How are the filaments in the S1 drying oven dried?

The filaments in the drying oven are dried in the following two ways:

  1. The desiccant actively keeps dry.
  2. Passive drying is achieved by clicking the heating and drying filament function.


  1. Is there a cavity heating function?

There is no cavity heating function, but when the nozzle and the hot bed are heated to the highest temperature and fully enclosed, the maximum cavity temperature can reach 50℃.


  1. How to deal with the problem of blockage?

First, you need to determine if there is actually a clog. If the machine reports a clog but the extrusion is fine, then it is a false clog alarm. Here are the situations where the filament cannot be extruded and the corresponding solutions:

  1. Problem phenomenon

(1). Click to feed, no filament is extruded;

(2). The filament suddenly stops extruding during the printing process.

  1. Reason:

The nozzle or throat is clogged, and the extruder is blocked with filament.

  1. Solution:

Note: The disassembly operation needs to be carried out when the machine is powered off.

(1) . First, make sure that the filament is inserted all the way. If it is not inserted all the way, please unplug the pneumatic connector at the effector and insert the filament firmly here. Click feed, wait for the nozzle temperature to rise to 240°C, and automatically load the filament.

(2). If the filament is extruded, use the silver needle in the accessory box to clear the nozzle, and click again to load the filament.

(3). If there is still no filament extruded from the nozzle, try to exit the filament and click "Exit". A pop-up window will appear. Please select the appropriate temperature to exit the filament according to the printing filament. It is recommended that low- temperature filament be returned at 180°C, and high-temperature filament be returned at 240°C;

(4). Unplug the pneumatic connector at the effector and pull out the filament;

(5). Disassemble the effector and check whether the throat or extruder is blocked;
