External material : flexible filament settings

Hi,

I try to print flexible filament (ninjaflex semi-flex) with my M200.

At 245C I have jamming issue. The filament do a loop around the extruder gear a few minute after the print has been started.

I must set the temperature to 265C to finish the print.

Has anyone manage to print this material correctly ? I am about to buy Sainsmart TPU which seems to be easier to print…

Try slowing down the extrusion,

Here is a good link to read through: https://talpadk.wordpress.com/2013/10/10/3d-printing-using-ninja-flex-filament/

I managed to print flexible material by removing the 4 screws on the extruder gear motor, and then adding some tape in the CCW direction in the extruder wheel. that way the material has no room to turn around the gear. If i remove the tape it will turn around the gear.

I made a part that fills the gap around the Extruder gear.

But, the raft can not be output well at the temperature zone recommended by the flexible material manufacturer.

I am happy that I can change the printing speed of rafts.

Does it work? I can prepare a ZCODE for you with more space between raft and first layer so raft removal should be bit easier, just let me know. 

edit: I believe that bottom part is needless :>

The red mark part of this picture is unnecessary.

It seems there is nothing in CAD data.

I need to recreate it later.

If you increase the space between the raft and the model first layer, will not the model be adhered to the raft even if it is printed at a high temperature that does not emit a click sound when drawing rafts?

No, it shouldn't. I'm going to slightly increase space between. Which profile you are using to print TPU?

I used the ABS base.

I would like to select a 0.09 mm pitch in the future.

Hi Marcin,

We are also trying to print using a elastomer (https://www.nexeo3d.com/nexeo3d/ccrz__Products?categoryId=a6a44000000GolZAAS&isCSRFlow=true&portalUser=&store=&cclcl=en_US), bt have also found that the raft is impossible to remove. I have read about using an earlier version of Z-Suite, adding a pause after the raft, removing the raft during the pause, and inserting a shim plate measuring 1.5mm high to fill the gap. Is there a more simple way around this? Is it possible to create a space between the raft and the first layer using the standard software?

Many thanks

Luke

try printing the raft in abs, pause print, unload abs, load tpu then finish the print off

Has anyone tested Arnitel TPC from Nexeo solutions?
