The Owl and the Pussy Cat went to sea, with their friend the Rubber Duck

So next in my series of alternative 3D Printing filaments was going to be – not Flexifi.  Now don’t get me wrong I really like this stuff, but what I originally purchased to 3D Print, and got pretty excited about, was Carbon Fibre Filament. However upon receiving a sample (and not conducting much research on the stuff before ordering it) I came to realise printing Carbon Fibre on the Wanhao 6 was going to be a more difficult feat than I thought, mainly due to the high temperatures required, which goes beyond the recommended levels of the Wanhao Duplicator 6. I have been informed that its possible, but requires some upgrading first. So that will have to be a story for another day.

Like a few other flexible filaments on the market, Formfutura Flexifil is excellent for prototyping items that need some rubbery give, such as mobile phone cases or other covers that need to pop on and off. You can also do fun things like print your own real rubbery rubber duck! Because ya know, squashy is amazing.


Formfutura Flexifil  is good fun and very easy to print with on the Wanhao Duplicator 6. The D6 copes easily with feeding the material into the print head and extrudes well on  the recommended slower setting of 30mm/s, and also prints just fine at 60mm/s (see the owl pic. Head only missing as I ran out of filament! But the quality is still fine) Some of the supports are hard to remove and leave a bit of mess, but along with a touch of stringing, this is my only real criticism of the print quality.

I did find however that the material curls/lift off the bed (heated at 50C.) A higher heating temp may help prevent this, but I found reverting back to the good old double sided tape solution helps this. Use quality stuff however, the cheap tape is not so good.

So, as with the nice little cat at I printed for my good friends birthday, if you want a squish toy print at 15% infill. Any higher makes it a bit too firm, so defying the purpose of this material.


So that’ s it. Easy to use and fun. Get some here and give it a go.

Next post I hope to add some new upgrades finally to the Duplicator 6, including a better set up for cooling, prior to trying out some more demanding filaments.  Watch this space to see how i do this. Or failing that i my try PET see what happens.

Thanks again!
