Ninja flex

Recommended Posts

I was just at my local print shop picking up some filament and he showed me Ninja flex filament. VERY COOL.

Unfortunately, I don't think it would work on the ultimaker2 due to the way that the filament is pushed not pulled. Has anyone else seen it or had experience with it?

My time with my Ultimaker2 has made me realize that as much as I love several aspects about it, I think the extruder pushing the material through the bowden tube for a long distance is potentially inferior to an extruder that pulls. Any thoughts?

The examples that I saw of the Ninja flex printed very nicely on Lulzbot and Replicator

Just found this thread. Great information here.

It's a matter of two evils. Either you use a Bowden cable and gain a light print head, improving print quality and speed but introducing some slack in the filament feed, or you use a direct feeder on the hot end and gain a lot of weight and thus problems.

There is a best of both worlds solution in development in the form of a flexible shaft, but the judge seems still out on that one. Also, some people seem to have a little more luck printing flexible material with Robert's feeder, although results are not guaranteed.

Thanks Zumfab, at some point I will catch up with everyone and know what is going on. Is there a comparison of all the most current extruders that have been created and offered up? Do most of the folks here that are using the U2 and are advanced printers have a modified or different extruder?

Thanks

My temp sensor cable is faulty and I will have to replace it maybe now is the time to also look into changing my extruder too something a little better as well.

Ninja Flex print ok if you change the feeder.

You can print Roberts feeder which contain a guide for flexible filament.

You can find a lot of useful info on flexible filaments here including ninja flex settings:

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
