Where can I purchase recycled polypropylene filament for a 3D printer?

Where can I purchase recycled polypropylene 3D printer filament?

I am a research student interested in using recycled 3D printing filaments in my ultimaker for a university project on sustainable design. I was using polypropylene because I needed the housing to be chemically inert. However, I cannot find any recycled polypropylene filaments in my local market or on global searches. Does anyone know a source or company in which I can obtain recycled polypropylene filaments (2.85 mm ideally). Thank you for your assistance.

Sources for polypropylene?

Can anyone recommend viable polypropylene fabric sources in the US? Both spunbond and meltblown.

The only widely available material I could find is the Pellon 915 Cambric interfacing, which is spunbond. I could not source any meltblown fabric.

Planned use is as insertable, possibly disposable filters in double layer cotton masks.

Designed a slightly different mask! 6 layers - 3 breathable silk and 2 metal/silk (called lamΓ©, with electrostatic properties), plus 1 layer of polypropylene (fabric interfacing) for filtration, comfortable ribbon ties instead of elastic reddit.com/gallery/k3u4y0

Canada now recommending use of 3-layer mask to prevent COVID-19 spread. Many disposable masks already have 3 layers, generally with a polypropylene filter. The recommendation mainly applies to homemade masks; public health agency advocates inclusion of 3rd layer of fabric. twitter.com/cbcalerts/sta…

What type of masks are required for just polypropylene swords?

Me and some friends are just getting into this and barely have money do we need expensive masks if we are just using polypropylene swords? Could we use something like an airsoft mask instead? If we have to use the special masks do you guys have any recommendations?

does anyone know a company or such that does custom polypropylene items?

I have neither the tools or time to make some swords myself, but I want to find some more exotic blades to start practicing with like the falx, sicca, kopesh, or others I'll find as time goes on. Has anyone found a decent small business or company that does custom jobs?
