3D Printing With VHS Tape Filament -> multiple tapes are twisted into a
single filament.
Print rate is slower than eg PET but dimensionally good. Also magnetic and
rather black.
Video - 11 minutes. Russian with good subtitles

If you have a pile of old VHS tapes collecting dust in your attic or
basement that you know you'll never watch again, either because all of
those movies are available on DVD or a streaming service, or because you
haven't had a working VCR since 2003, there might be a way of putting them
to good use in another way. With the miles of tape available in just a few
cassettes, [Brother] aka [Andrew] shows us how to use that tape as filament
for a 3D printer. (Video, embedded below.)
The first step of the build is to actually create the filament. He uses a
purpose-built homemade press to spin several tapes into one filament
similar to how cotton or flax is spun into yarn. From there the filament is
simply fed into the 3D printer and put to work. The tape filament needs to
be heated higher than a standard 3D printer filament so he prints at a much
slower rate, but the resulting product is indistinguishable from a normal
print except for the color. It has some other interesting properties as
well, such as retaining its magnetism from the magnetic tape, and being a
little more brittle than PET plastic although it seems to be a little
stronger.
While the VHS filament might not be a replacement for all plastic 3D
prints, it's still a great use for something that would likely otherwise
head straight to the landfill. There are some other uses for this magnetic
tape as well, like if you wanted to build a DIY particle accelerator.
