Hi community,

I'm new, but I'd like to start a discussion right away!

About me: 27 yo, BSc. Material Science, from Germany near Nuremburg.
I've been involved with 3D printing since the last two years. Since then I built quite a few 3D printers (mainly MendelMax 2.0) and am very happy with my results and the experience I've made. I also constructed a filament Extruder (Bachelor thesis) which was a lot of fun and frustrating at the same time (but mostly fun ). You can look it up on thingiverse (JuliusG, filament extruder).

As much as I love tinkering with 3D printing and filament extrusion I am missing functionalized filaments. I know there are a few flexibles or conductive (more or less) or pretty strong fibre reinforced filaments out there...but limited. These things are coming, I know, don't get me wrong! But I would like to know how you feel about this? What would you like to have or where would you like to see improvement?

I'm thinking about: anti-bacterial, porous, hardly inflammable and thermo resistant, more conductivity, acid resitant, adjustable transparency and flexibility...tell me your fantasies

What your opinion on this? Thanks for your replies!

Julius
