Anyone tried polypro yet? This is a highly durable semi soft plastic and need something
like this for planned new projects in 2015.

john i dont think i have ever seen pp filament yet.....have you? im not sure if there is a reason for this or not. perhaps its unsuitable for 3d printing in some way. the closest thing though that i have found is taulman bridge.

I tried extruding some. It came out naaaasty. Very blobby and uneven...

interesting. when i plastic weld with it the stuff seems kinda smooth and semi easy to work with. of course that means nothing to a 3d printer but i guess thats why you dont see it available. the bridge filament is very close anyway. it sticks better than all the other nylons i have used but still warps like a sob.

Gizmo Dorks has polypro and it's listed on Amazon.

Here's info off their website:

Polypropylene Filament

Polypropylene (PP) filament is a new semi crystalline thermoplastic used in Fused Filament Fabrication (FFF). PP filament has a high level of flexibility. Printing temperature for Polypropylene filament is around 210 – 230°C. Some users have reported great printing results with a printing temperature between 250 – 280°C. Every 3D printer is different, and please check if the printer can print at high temperatures. Many filament tubes will melt at temperatures higher than 260°C. For best results, heat the build platform to 120 - 150°C or as high as possible.

Kinda hate to be the first with my limited skills

john see that last bit of info they gave you. telling you to really crank up the heat on the platform. thats probably because it warps really bad. same deal with polycarb, delrin and few others. i would be interested to hear your results though.

Above 255 extruder temp is something I will not attempt with my v3b hot end.
