Polycarbonate filament, also known as PC filament, is a strong thermoplastic
material used in 3D printing. Polycarbonate filament has many uses in everyday
applications. It is a good electrical insulator while having heat-resistant
properties. Polycarbonate is used in data storage for compact discs, DVD's and
Blu-Ray's. It is used in many medical applications as well as for parts in
today's advanced phones. It is commonly used in eye protection, and it is used
after lamination to make bullet-proof glass.
Polycarbonate filament is such a great 3D printing filament material because of
it's strength. It is a really strong material while still maintaining
temperature resistance. Polycarbonate does not shatter like plexiglass. It tends
to bend and deform similar to hard rubber until it eventually breaks. It also
has high optical clarity. PC absorbs a lot of moisture in the air. It is a
hygroscopic material, and it is best to store in an air tight container when not
in use. Even during use the material can become unprintable within a 24 hour
print if in a humid environment. Therefore, keeping in an airtight container
during printing as well is ideal. Dry PC filament will print more clearly.
Filament that has absorbed moisture will print white as well as pop and bubble
during the print.
Extruding temperature for Polycarbonate filament is generally around 260°C,
depending on the printer. PC 3D filament slowly softens when heated, unlike PLA
which has a high transition temperature. Slower print speeds are preferred as an
increase in temperature is required for faster prints. Polyimide tape (Kapton
tape) should be used on a heated bed, ~120°C, with ABS juice on top of the tape.
Some users prefer applying glue or superglue on a glass bed and then heating to
~120°C-130°C. Please do not inhale any fumes. Heated up superglue can release
toxic fumes, so only use in a well ventilated area.
Printing temperature : 255°C -
300°C depending on part and printer type
- Print speeds : 30mm/s
is ideal, can go up to 60 or 80mm/s
- Store airtight in use
and when not in use, absorbs moisture
- Print on a heated bed
- Only use in well
ventilated areas or in a ventilated system
