Recreus Filaflex 60A is printable on a MK4

 

Indeed, I have been trying for a long time to find the right combination to print Recreus Filaflex 60A. I have worked for a long time and still work with Fiberlogy Fiberflex 40D. I had no problems with this filament. However, I wanted to try to print with an even more flexible material. I came across the company Recreus which produces very flexible filament. So I got myself some Filaflex 82A as well as Filaflex 60A. While the 82A is not too difficult to print, the 60A is almost impossible to print. I tried a lot of possibilities, even trying to print with a 0.8 nozzle, but nothing worked. The prints were all of very poor quality. The flow of the filament was constantly interrupted which resulted in poor adhesion and tearing of the material inside the object. So I consulted several forums and here is the answer to be able to print Filaflex 60A:

1) First you have to remove the ball holder assembly which is one of the main causes of bad prints. Indeed the ball blocks the filament which is transported from the gearbox to the hotend. Because Filaflex 60A is an ultra flexible material, it is stretched between these two elements which implies that the quantity of material available at the hotend is no longer sufficient to be able to print continuously.

2) Download the configuration for the different Filaflex filaments on the Recreus website. These parameters have been tested and work impeccably with the MK4.

3) On the MK4, you must load the filament manually by choosing the Flex filament as the base filament. Do not worry if smoke escapes during loading. Subsequently the correct printing temperature is set in the configuration.

4) If you get a message that this is a different configuration when loading the print than what is specified in the gcode, ignore this message and continue.

5) When it comes to fairly large and complex objects to print you absolutely must work with supports because as the material is very flexible it risks being deflected when the nozzle is in contact with it.
