Sigma R19 - Filament

Filament
The Sigma R19 printer gives the best printing results
when printing with BCN3D Filaments, although it
accepts many other materials from other
manufacturers.
BCN3D Filaments are industrial-grade materials
designed to deliver outstanding results for BCN3D
printers. BCN3D Filaments, formulated to ensure the
highest print quality, are common polymers in several
industries and cover the majority of the technical
applications. Those filaments are: PLA, ABS, Nylon,
PET-G, PVA, TPU and Composites. Visit our
dedicated website for detailed information about each
one. Furthermore, you will find the Technical and Safety
Datasheets of all of them.

A brief description of those materials is given below:
PLA
PLA (Polylactic Acid) is a biodegradable, sustainable and
food safe polymer made from organic sources.
It is the most common used filament in FFF 3D printers
for its ease of use and wide range of applications,
specially those not mechanically or thermally
demanding. Definitely a good starting point to learn
about the 3D Printing manufacturing process.
PLA is compatible with PVA supports.
Once printed, PLA parts can withstand operating
temperatures up to 50ºC.
To ensure good bed adhesion use 3DLac, Dimafix or
Glue Stick.
ABS
ABS (Acrylonitrile Butadiene Styrene) is one of the
most common technical materials in several industries
around the globe. Its great mechanical and thermal
behavior make ABS the ideal polymer for countless
applications.
Traditionally a challenging material to print with FFF
printers, it has been re-formulated to ensure good
interlayer adhesion and to reduce warping. Printing with
ABS is more complex, and requires a certain amount of
care: it is not recommended for non-experienced users.
Once printed, ABS parts withstand operating
temperatures up to 85°C.
To ensure good bed adhesion use Dimafix.
Do not use layer cooling fans and avoid drafty or cool
rooms for best results.
For a better print quality use the BCN3D enclosure for
the Sigma.
Printing overhangs is easier if the layer fan is used.
It has average mechanical properties, although it
becomes slightly brittle when printing irregularly-
shaped objects. At operating temperatures of 50º C
or more, the mechanical properties and rigidity of the
objects may decrease.
