Overview

NinjaFlex

Are you tired of braking parts made with ABS and PLA? Ninja flex from fenner drives is athermoplastic elastomer based material with awesome rubbery properties.

Wearables, LED Diffusers

It's great for wearable projects like our FLORA wrist band (http://adafru.it/d8h)and makes greatsewable diffusers for our NeoPixel LEDs like on our Chemileon Scarf (http://adafru.it/cez).

Looking for a way to soften the super bright glow of a NeoPixel? Ninjaflex works great as adiffuser (http://adafru.it/d5Z). We made round domes (http://adafru.it/d5Z)and spiky caps thatnicely fit over our sewable NeoPixels.

During the holiday break, we made a hallow snowman and a pumpkin to test how well thematerial handles geometry. Not only did the parts retrain surface detail and shape, they lit upquite nicely. Were definitely working on incorporating this material in more wearable projects!

Bumpers, Stoppers, Insulation

Perfect for protecting objects against impact, you can make custom stoppers, gaskets forsealing junctions, insulation between two surfaces or even add non slip feet for projects.

Stretching our iPhone Bumper design (http://adafru.it/d8i), you can see just how elastic thismaterial is. Using our bare hands, we couldnt quite rip it apart. With enough thickness, you candesign some really tuff stuff!

Grips, Buttons, Buoyancy

Customize a comfortable handle for all uses. Great for replacing missing rubber buttons oreven small tires. Keep that camera afloat and eliminate sinking, Ninjaflex floats!

Usage

Processing Guidelines:

Recommended extruder temperature: 210 - 225CBlack requires 225C for proper adhesion.

Recommended platform temperature: 30 - 40C

Features:

High elasticity and excellent abrasion resistance

Excellent build platform adhesion and bonding between layers

1.75mm filament spool = .50 kg

Extruder Upgrade

If your a makerbot owner with an plunger extruder, you will need to upgrade you extruder.Luckly, you can print your own parts! This design incorporates a spring-loaded arm to squeezethe filament between the drive gear and a bearing with a constant amount of pressure.

Build Plate

Removing flexible parts from the build plate is easy and well, quiet pleasing. Most 3d printingoperators know how fun it is to remove ABS and PLA prints. With Ninjaflex, It's both fun andscary to remove because its so flexible and elastic. The first test prints we couldn't help butfeel like we were deforming the shape or going to tear it apart. No need to scratch up that build

plate with a scrapper when your part is strong and flexible, just pull and peal!

If you need a print with a glossy flat finnish, Ninjaflex sticks great to Kapton tape without aheated platform.

Ninjaflex also has great adhesion to blue painters tape as well as acrylic and glass build plates.

Properties

Very flexible. Almost silicone-like. It stretches, bends, twists and folds without deforming theprinted objects original shape. Sturdy enough to hold its own shape and doesnt flop over witha minimum wall thickness of 2mm.

Strength

The stress test in the photo above shows our iPhone bumpers holding 10 pounds of weight.The bumper retained its weight and didn't stretch itself out of its original shape.

FlexibilityIn the flex test above, we see the filament can actually be tied in a knot without breaking likePLA and ABS.



9/10

Removal is easy with no spatulas required! Just pull and peel your object right off the buildplate!



10/10

Tips

Use a minimum wall thickness of 2mm to keep your design sturdy.

Cleaning Prints

Use sharp scissors to remove the access material left behind during the print. You can bendyour prints excessively to get in between crevasses and remove tiny artifacts. To removerandom tiny leftovers, stretch out the small piece and cut close to it's wall using Flush diagonalcutters (http://adafru.it/152).

Optimizing PartsObjects with geometry that make the head move across multiple islands is going to haveconsiderable artifacts that may require clean up.
