Proto-Pasta Magnetic Filament for 3D Printing Behaves Like Metal, Is Even Rustable
ment is slightly more brittle than standard PLA and requires extra
care when handling. It is also more abrasive than standard PLA
and may require nozzle replacements and first layer adjustments.
The rustability feature is popular for making items with a rusty
patina giving an artifact appearance.
With advanced materials like Proto-Pasta iron-filled filament for
3D printing, the possibilities of additive manufacturing for functional
parts having magnetic properties may be catching up. Traditionally,
subtractive technologies like CNC milling have been
the dominant solution for industrial manufacturers and for making
prototypes while additive manufacturing that involves magnetic
materials has remained largely in the realm of hobbyists.
They are still the typical customer type and primary market focus
of Protoplant in Vancouver, Washington but functional applications
of its carbon fiber high-temperature PLA have expanded.
PLA is the short term for polylactic acid, a thermoplastic monomer
derived from renewable, organic sources such as corn
starch or sugar cane. PLA composite is a combination of PLA
with natural fibers by compression molding, extrusion, injection
molding, filament winding and other methods.
Produced in 1.75mm and 2.85mm diameters, small quantities of
Proto-Pasta are packaged in coils while larger amounts come in
spools such as 2kg of filament on a 12-inch diameter spool.
Proto-Pasta filament comes in an array of colors and characteristics,
serving primarily the hobbyist market. There also is an electrically
conductive PLA composite.
Proto-Pasta Magnetic Iron PLA is metal-filled carbon fiber that
is ferromagnetic and behaves like metal. It responds to magnets
and behaves similarly to pure iron. Encapsulated in plastic, the
iron maintains a stable matte, cast metal finish as printed, but
can be rusted when desired. It has a weighted feel being 1.5x the
density of standard PLA. It attracts magnets, neodymium type
recommended for strongest attraction. Induction at magnetic
saturation is rated at about 0.15 Tesla. Relative permeability is
between 5 and 8 independent of frequency up to 1 MHz. The filaOne
of only a few makers of magnetic filament for 3D printing,
Protopasta was founded in 2013 and specializes in the production
of filaments for 3D printing. The company started with a passion
for exploring the filament extrusion process and has since
grown to a professional and robust operation, offering a range of
filaments to meet the needs of makers and 3D printing enthusiasts.
