3DGence INDUSTRY F340 printer is equipped with two extruders and two hotends. Thanks to this, two materials can be used
in one printed model. This solution makes it possible to:
•print two-colour models,
•to print functional models that combine characteristics of two specific materials in the required manner,
•print geometrically complex models that require soluble support structures.
With its extensive range of temperatures achieved, 3DGence INDUSTRY F340 printer can use a wide range of printing
materials available in many colours. The Certified Material Base, available at www.3dgence.com, has been created for
3DGence INDUSTRY F340 printer. The Base contains the list of all materials supported by the Smart Material Manager (SMM)
and their typical applications.
3DGence recommends that the materials from the Certified Material Base should be used. These materials are supported by
the SMM system and they make it possible to achieve accurate print parameters, ensure automatic detection of material
type and, consequently, guarantee the highest print quality. More information on the SMM system can be found in chapter
IV, point 4. 3DGence does not limit the use of non-certified materials. However, the application of such materials prevents
the use of SMM system.
3DGence is not responsible for the quality of printouts made of the materials other than those included in the Certified
Material Base and for damage caused by the use of such materials as well as it does not provide support for the quality of the
printouts made of the filaments other than those included in the Certified Material Base.

Fig. 1 Designation of printer axes
1.2. Kinematic system
The printer works in the Cartesian robot's kinematics. The axes described as X and Y move the hotend in horizontal plane; Z
axis moves the printer's hotend vertically (fig. 16). Dimensions of available printer's working space:
X: 260 mm,
Y: 300 mm,
Z: 340 mm.
Printed object must not exceed the above dimensions. The printer's software will prevent an attempt to generate a file that
exceeds the maximum dimensions, but these dimensions must be considered when designing the model for printing.
Fig. 16 Designation of printer axes
1.3. Heatbed
The printer's heatbed moves along Z axis. The heatbed is shown in fig. 17. The entire mobile heatbed is marked with a lighter
colour. The darker colour marks the actual printing area. Made of ceramic plate, the heatbed guarantees good printout
adhesion even for several dozen hours of continuous operation of the printer.

3DGence INDUSTRY F340 | version 04.2018
1.4. Filament chamber
3DGence INDUSTRY F340 printer is equipped with a heated filament chamber. The purpose of the filament chamber is to
keep filaments in an increased temperature environment. This prevents moisture and change of filament parameters and
dimensions. Closed housing protects the filaments against direct exposure to sunlight, contamination and accidental damage.
Inside the filament chamber there are two holders for filament spools. They are connected to a measuring system that makes
real-time measurements of the weight of available material. In addition to the spool holders, there is a heater in the chamber
that regulates the temperature inside the filament chamber.
1.4.1. Adjustment of filament chamber temperature
The filament chamber temperature is adjustable by means of the thermostat located on the right side inside the filament
chamber. This option can be very important when using the printing materials with a very low softening temperature. The
temperature adjustment is made using the keys on the left side of the thermostat (fig. 18). The manufacturer recommends
setting the temperature in the filament chamber at 65⁰C. For PLA printing, the temperature should be set to 40⁰C.
ATTENTION:
Under no circumstances should you touch the chamber heater during printer operation or lean any objects against
it. The filament chamber must not be used for storing objects other than filaments!
1.5. Extruder modules
3DGence INDUSTRY F340 printer is equipped with two material extruding systems - hereinafter referred to as extruders (fig.
19). They are located in the working chamber, above the dual hotend module, and connected with the filament chamber by
means of the feeding system. Extruder 0 (Tool 0) is responsible for feeding the base material to hotend T0, while extruder 1
(Tool 1) is responsible for feeding the supporting material to hotend T1. Tool 1 is located closer to the user facing the printer
(fig. 19). More information on loading the materials and operation of extruders can be found in chapter III, point 4.
