Fig. 1 Rating plate of the unit
3. FFF TECHNOLOGY
The FFF (Fused Filament Fabrication) technology employed by the 3DGence INDUSTRY F420 printer works by depositing the
thermoplastic layer by layer on the heated print bed, thus bonding it to previous layers. This material is a printer consumable.
It comes in the form of a material with a strictly defined diameter, wound on a spool (Fig. 2). 3DGence INDUSTRY F420 uses
only 1.75 mm diameter material (filament).
The 3DGence INDUSTRY F420 printer can work with many types of process materials. For 3DGence printers, a Database of
Certified Materials has been developed, available at www.3dgence.com. The database contains a list of all materials tested
and recommended by 3DGence, for which print settings have been prepared in the dedicated software 3DGence SLICER 4.0.
3DGence recommends using filaments listed in the Certified Material Database. These materials are supported by the SMM
system in the 3DGence INDUSTRY F420 printer and allow for precise print parameters, automatic material type detection and
consequently guarantee high print quality. For more information on the SMM system, see Section III, point 6.
3DGence does not restrict the use of uncertified material but using them prevents the use of the SMM system. 3DGence shall
not be responsible for the quality of prints made with materials which are not listed in the Database of Certified Materials, nor
shall 3DGence be responsible for any damage caused by using such materials for printing and shall not provide support for the
quality of prints made with filaments which are not listed in the Database of Certified Materials.

1.7. Connection specifications
Below is the electrical characteristics of the 3DGence INDUSTRY F420 device. The connection should be appropriate to the
values provided.
Voltage: 230 V AC (210-250 V AC).
Frequency: 50-60 Hz.
Maximum power input 20 A.
In Europe
It is recommended to connect the device to the mains directly, e.g. in a cable box or with busbars using 4 mm23-wire cable.
If no direct connection is possible, there is a second connection option. Due to the high maximum current draw of 20 A
,the device can be powered via a 3-phase socket with a maximum allowable current of 32 A according to IEC 60309 and a 5-
core 4 mm2cable. 1 of 3 phases and a neutral wire are used. If more machines are connected to the mains, in order to ensure
an even load on the mains the devices should be connected to successive phases (e.g. Machine 1: L1 + N, Machine 2: L2 + N,
Machine 3: L3 + N, etc..).
In USA
The device is plugged into the mains phase-to-phase (2x120 V, ϕ180°) via a 20-ampere NEMA 6l-20P plug via a 3-core 4 mm2
cable.
Alternatively, the device can be connected to the mains directly, e.g. in a cable box or with busbars using 4 mm23-wire cable.
