In this video, I solve a problem that has been pinching me for a long time. My tungsten carbide wedding ring looked fancy but was painful to wear at the gym. Being the crafty fox that I am I decided to make my own wedding band that can flex to the contours of the bar and my finger without pinching my digits. I used a variety of Ninjatek products and they all performed well. Ninjaflex, Semiflex, and Cheetah all printed beautifully without any problems once I got the settings dialed in. I ran the flexible rings through a gauntlet of tests at the gym to make sure they were flexible enough and would not pinch. Even the most rigid of the three flexible filaments, CHEETAH, was still flexible enough to be comfortable to wear at the gym.

LIST OF FLEXIBILITY~~~~~~~~~~~~~~~~~~~~~~~~~~~

I ran my standard failure test and was surprised to see that NINJAFLEX was stronger than the other 2. The ring thickness was 1.2mm which was printed in 2 perimeters.

PULL TEST RESULTS~~~~~~~~~~~~~~~~~~~~~~~~~~~~
CHEETAH – 49lbs
SEMIFLEX – 45lbs

PRINT SETTINGS~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ NINJAFLEX:
230c Hotend
0c GLASS Build plate
20mm/s Print Speed
0.2mm Layers
0.6mm Nozzle
115% Flow or 1.15 Extrusion Multiplier

230C Hotend
0c GLASS Build Plate
*40mm/s Print Speed*
0.2mm Layers
0.6mm Nozzle
115% Flow or 1.15 Extrusion Multiplier

1) Heat up hotend to 230c and extrude a few inches of NYLON filament to ensure it has pushed out any other material from nozzle.
2) Set hotend to 130 and let hotend cool until temp is @ 130
3) Grab filament and help extruder pull out NYLON from hotend *POP*
4) Tip of filament should look like the inside of your nozzle, if it is stringy and melted looking then you need to let the hotend cool more before pulling. If the NYLON does not come out and you are pulling hard then bump hotend temp up 10c

A demonstration of flexible filament with these 3 tests: squish test, stretch test and flex test to show the differences of NinjaTek’s NinjaFlex, SemiFlex and Cheetah.

Open your world to flexible prints with low-tack NinjaFlex filaments. NinjaFlex creates extremely flexible, strong prints, extending the capabilities of many of today’s 3D printers.

Think flexible filaments like Ninjaflex are hard to print? There are a couple things to watch out for, but anyone can do it.
If you are needing a part to bend stretch or flex you have to see what this stuff can do. With the proper print settings you can get some amazing prints. The example prints I show are a mini rock crawler tire, a vibration dampener, and a custom printed o-ring to seal my acetone vapor polishing chamber. I walk through the steps to make a perfect print and give some pointers on how to modify prints settings to get the exact. Brought to you by Netherbot
A new way to use Flexible Filament

In workshop, we realized that it was possible to take advantage of flexible filament properties to make modular objects!  By stopping your print and adding a thin metal rod you get bendable parts.
