A filament which you are using now in 3D printing has several problems.
You have to waste a remaining filament always,
you have to wait to change a remaining filament to a new filament
and a printing might be failed if you miss a right time to change filaments.
These are very headache problems in 3D printing but nobody have thought about it.
I developed NEXTFILA - the connectable 3D printer filament system to solve these problems.
There are lots of things to solve if this connectable 3D printer filament system would be adopted to everyone.
So, I make this forum to listen opinions about this connectable filament system.
This connectable 3D printer filament system will help your printing, save a cost and even it will help to save the environment because it can reduce waste filaments.
Your contributions and your opinions will be great help to come out this "NEXT GENERATION FILAMENT" system to the world..
