Wood filament (PLA infused with wood dust/wood fibers)
results in objects with the look and feel of wood. A number
of di↵erent brands, incorporating di↵erent types of woods, are
available. Note that it’s moderately difficult to work with (as
opposed to plain PLA which is relatively easy): it tends to be
more finicky about print temperature (which typically needs to
be a bit higher than that for Polar 3D PLA), is subject to some
shrinking du r i n g printing, and may not adhere as easily as plain
PLA.
Conductive PLA is PLA infused with conductive carbon. It
allows printing low-voltage el e ct ro n i cs. It tends to need to print
at a slightly higher temperatur e than plain PLA, and while it
is considered fairly easy to print, and is not reported to be par-
ticularly abrasive on the extruder nozzle, it is a little harder to
get it to adhere (even to itself); also, it tends to be expensive
compared to regular PLA.
Carbon Fiber PLA is PLA m i x ed with small, chopped ca r bon
fibers. It results in strong objects, much stronger than regular
PLA, but is extremely abrasive on the extruder nozzle; expect
to have to replace your extruder nozzl e after printing only 550g
(half a regular spool) of carbon fiber PLA .
Metal PLA is PLA combined with fine metallic power, such
as bronze powder, brass powder, copper powder, aluminum pow-
der, or steel powder. Objec ts 3D printed using metal PLA fil-
ament will look and feel as if they were made of metal, can be
polished like metal, and will be denser (heavier) than regular
plastic objects, hefting more l i ke metal. However, metal PL A
is quite abrasive on the extruder nozzle, especially when the
incorporated metal is a harder metal than the brass of the ex-
