User Manual 8
IDEX / FFF technology
The Sigma R19 is a 3D printer which uses
fused filament fabrication (FFF) technology,
which manufactures objects by depositing
molten material in a series of layers. Objects
are created using a digital model of the object,
which is sliced into thin layers. When printing
the extruder print head moves along the axis
to deposit the material for one layer at a time,
before moving slightly upwards to begin printing
a new layer. This process is repeated until the
object has been completed.
Since FFF technology requires deposite material on top of plastic previously
extruded, certain complex geometries with overhangs require additional support
structures to be successfully printed. However, printing supports with the same
material of the model can result in many post-processing problems.
The Independent Dual Extruder System (IDEX) is BCN3D’s unique approach to avoid this issue and also offers a
bunch of new key features. The two extruders are controlled independently, so that when one extruder is not being
used it can be kept away from the printing area to prevent the plastic from oozing onto the object and spoiling the
final result.
Having two independent extruders offer the user the ability to print, not only with soluble supports, but also multimaterial objects, print in two different colors or even combine different nozzle sizes to get more resistant parts or
cut down the printing process.
Safety
To avoid potential residual risks the user should read and understand the following safety measures (you are
strongly advised to read this before using the machine).
To highlight the areas where extra care should be taken, safety alert stickers have been affixed to the relevant parts
of the machine to warn the user of potential hazards.
Any modifications made to the machine without the manufacturer´s approval will invalidate the product´s
Declaration of Conformity (CE) and warranty.
Consequently, the BARCELONA THREE DIMENSIONAL PRINTERS,S.L. ARE EXEMPT FROM ANY LIABILITY IF THE
USER DOES NOT FOLLOW THE INSTRUCTIONS FOR USE:
User Manual 9
Safety
Very important. As with any other appliance, do not touch the terminals of the mains, the

Mirror and Duplication modes
The Sigma features two new printing modes:
Mirror and Duplication. In these modes both
toolheads work simoultaniously.
To do it successfully it is key important to make
sure both nozzle tips are exactly at the same
height. However, due to manufacturing and
assembly tolerances the offset between tips
can be up to 0.5mm.
The Sigma automatically corrects the offsets
when printing in Duplication/Mirror modes.
However, this correction distorts the first layer
of the model by repeating it as many times as
needed.
User Manual 23
Mirror and Duplication modes
To avoid such distortion there are different options:
1. Enable raft in BCN3D Cura.
The offset will be corrected in the first layers of the raft,
so the model won’t be affected by any Z offset.
2. Install shims to mechanically correct the Z offset.
Printing a raft takes time and spends material. For
those users planning to use frequently the Mirror or
Duplication modes, it is highly recommended to install
the shims when it is suggested during the Printer Cali-
bration process.
User Manual 24
Installing shims
During the Printer Calibration process or before printing
a job with Duplication or Mirror mode, the Sigma may
suggest you to install shims to correct the Z offset
between nozzle tips.
Once you confirm you want to install the shims,
remember de number of shims to install on which hotend and just follow the screen instructions:
1.
Wait until the printer cools
down to avoid any dangerous
manipulation.
3.
Unscrew the 2 bolts at the

Filament: this menu allows you to manage the filaments of the printer. The menu functions are:
–Load: This is for loading filament into one of
the extruders. You should first select the side where
you want to load the filament. Next, you should insert
the filament into the extruder following the onscreen
instructions (the extruder should first reach the right
temperature, which may take a few minutes). Once you
have inserted the filament the extruder can be adjusted
slightly to allow you to load the rest of the filament.
When purging we recommend you pull out a generous
amount of filament to ensure the extruder is purged
correctly.
BCN3D Filaments presets are offered, but it’s possible
to load different materials. Just select Custom and set
the 2 temperatures demanded. Follow the manufacturer indications to set the Printing Temperature and the
Heated Bed Temperature.
–Unload: This operation is the opposite of the
operation described above, although it is performed
in a similar way. After you have selected which side
you want to remove the filament from, wait until the
hot-end has reached the right temperature and then
remove the filament.
–Purge: This menu allows you to control the
temperature of the two hot-ends, and extract or
dislodge clogged filament. In order to be able to move
the filament, the temperature difference between the
objective temperature (under the thermometer) and the
actual temperature (under the extruder icon) should be
less than 10º C.
–Light intensity: Use the toggle to adjust the LED
luminosity.

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.
https://www.bcn3dtechnologies.com/en/3d-printer/
filaments/
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.
Printing overhangs is easier if the layer fan is used.
It has average mechanical properties, although it
becomes slightly brittle when printing irregularlyshaped objects. At operating temperatures of 50º C
or more, the mechanical properties and rigidity of the
objects may decrease.
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.
Once printed, PLA parts can withstand operating
temperatures up to 50ºC.
To ensure good bed adhesion use 3DLac, Dimafix or
Glue Stick.
User Manual 49
Filament
PVA
PVA (Polyvinyl alcohol) is a water-soluble polymer,
ideal to work as support material for multi-material 3D
Printing.
Optimized for the FFF manufacturing process, our PVA
works seamlessly with PLA, TPU, PET-G and Nylon,
becoming a reliable universal support material to print
complex geometries, large overhangs or intricate
cavities.
PVA supports allow to achieve better surface quality, to
orientate the part to get better mechanical properties
and even to print multi-component models and
mechanisms.
To ensure good bed adhesion use 3DLac, Dimafix or
Glue Stick.
PET-G
PET-G (Polyethylene terephthalate glycol-modified) is a
globally used co-polyester, from plastic water bottles to
cloth fibers and it is 100% recyclable.
As a technical material, PET-G provides good
mechanical properties and improved chemical and
thermal behaviors than PLA but with similar ease of
use.
Nylon
Nylon (polyamide) is an extensively used material for its
unique mechanical and chemical properties.
Thanks to characteristics like durability, flexibility and
resistance to corrosion, Nylon is ideal for multiple
applications in the 3D printing field, like end-use parts
or custom jigs and fixtures. It is compatible with PVA
supports.
Once printed, nylon parts can withstand operating
temperatures up to 50ºC.
To ensure good bed adhesion use Dimafix or Glue Stick.
For a better print quality use the BCN3D enclosure for
the Sigma.
TPU
TPU (Thermoplastic Polyurethane) is a versatile rubberlike flexible material.
With Shore-A hardness of 95, TPU is a resistant
material for several industrial applications, both
mechanical or chemical. Moreover, it’s been especially
designed to improve the 3D printing experience.
Once printed, TPU parts withstand operating
temperatures up to 60ºC
It has an outstanding chemical resistance, a great
dimensional stability and toughness and a good glossy
surface quality. PET-G also offers a good abrasion
resistance, a high humidity resistance and it withstand
operating temperatures up to 70°C. It is compatible
with PVA supports.
To ensure good bed adhesion use 3DLac, Dimafix or
Glue Stick.
For a better print quality use the BCN3D enclosure for
the Sigma.
To ensure good bed adhesion use 3DLac, Dimafix or
Glue Stick.
Composites
Composites are materials with a polymeric base infused
with other particles or fibers in different proportion.
From wood to metal particles to achieve an aesthetic
and attractive finish to carbon fibers to combine
lightness and mechanical performance, composite
materials for FFF printers unleash creativity.

General considerations
To ensure good adhesion between the printing surface
and the 3D printed part, you will need to use an
adhesive product that will be applied to the printing
surface before start printing. For general materials,
we recommend using the printing adhesive (glue stick)
included with the printer or a generic lacquer. If your
printed part has adhesion problems with the glass
printing surface, we recommend using alternative
adhesives, such as 3DLac or Dimafix. Dimafix is ideal for
technical materials or complex prints. You can find them
on our website https://www.bcn3dtechnologies.com/
en/3d-printer-spare-parts/
We recommend using an enclosure when printing with
technical materials such as ABS, Nylon or PET-G. It
provides a constant interior temperature to prevent
warping and protects your working environment from
potentially harmful particles thanks to the HEPA filter.
More information at our website.
Nylon and PVA plastic are hygroscopic, that means
it readily absorbs water from the air. Make sure they
are dry before printing. Place them in an oven or in a
dehydrator at 50 ºC for 6 to 8 hours. After drying, store
it in an airtight container with desiccant.

User Manual 57
Open source
Open source is a development model that promotes universal access by granting software licenses free of charge,
and also universal distribution, including subsequent improvements.
We believe that adopting an open source philosophy offers many advantages:
• More control: We can see everything that is happening with the source code, designs etc., and modify them to
suit our needs.
• It helps us learn: We can see and read the software designs that other people have made, which helps us to
become better programmers and engineers.
• Safety: Since the designs are open designs, a lot more people can modify and/or correct any errors that the
original programmer may have made.
• Making improvements quickly: The open source community provides a lot of information about how to improve the product. This helps us to fix errors and update programmes much more quickly.
Using open source licenses for the products we develop is a way of expressing our willingness to share, to collaborate with other people in a transparent way (so that others can see what we are doing and join in), to embrace
failure as a means of improving, and to expect, even encourage, everyone else to do the same.
BCN3D Technologies and its products would not be where they are today without the RepRap project and its open
source community. The RepRap project started out as an initiative whose objective was to develop a 3D printer
which could print most of its own components and be a low-cost printer. As an open source project, all of the designs produced by the project have been released under a free software General Public License (GPL).
This project does not only include hardware, but has been conceived as a complete ecosystem of tools for printing,
from the CAD/CAM software to the code read by the machine to print physical objects.
Sigma R19 printers use many open source tools and technologies, such as Marlin software and the Cura pre-processed software. The first controls all the printer´s components, while the second converts the 3D file into G-code,
a language the machine is able to understand.
Marlin firmware is published under a GPL license. This means that we must keep Marlin open, and must provide
our source code to end users. For this reason we have our repository on the Github platform, where we post all the
changes we make.
Cura software is published under an AGPLv3 license. This is the same as the GPLv3 general license but a paragraph
has been added to Section 13 which makes it obligatory to provide source code to those who use software through
a network. We therefore have repositories for each operating system so that users can access the source code.
Open Source is not only used for code, but also covers hardware. In our case all the mechanical and electronic parts
are published under a GPLv3 license.
BCN3D Technologies is firmly committed to open source initiatives, and we believe that with the help of the community we will be able to make better products.
