Linear rail system
Profiled rails and carriages guide the moving assemblies, carry loads in different directions, and resist tilting.
Rigid support and stable motion.
FGF PRO / PRINTER
FGF PROPrint directlyfrom pellets
A desktop 3D printer developed in-house. Work directly with industrial feedstock, choose materials to suit your needs and achieve print quality close to filament-based FDM printing.
/01Designed for
Designed for
pellet printing
The kinematics, mechanics and drives have been selected with the characteristics of a pellet extruder in mind.
The bed moves along X and Y
The extruder moves only along Z
FGF PRO uses XY bedslinger kinematics. The bed follows the toolpath in the print plane, while the extruder assembly moves vertically.
The heavy extruder does not accelerate or decelerate along X/Y. This layout allows greater freedom in extruder assembly weight and avoids a separate system for transporting pellets to a head moving in the print plane.

FGF PRO / XY BEDSLINGER
How the motion system works
X — left / right.
Y — forward / back.
The bed stays at a constant height.
Bed X/YExtruder Z
Select an axis. The upright stays fixed; the arm and extruder move along Z.
Heated chamber
A chamber sized to the bed
The chamber is mounted to the Z axis on moving guides, matches the bed dimensions, and moves with it along X and Y. The extruder is inside and moves along Z.
The chamber encloses the print area. There is no need to enclose the entire printer structure.
Ball screws
Ball screws move the assemblies with low friction losses. Compared with a belt drive, they provide stiffer force transmission and less elastic displacement under load.
This is useful for a loaded bed and a heavy extruder. No belt tension adjustment is required.
Drive rigidity and repeatable motion.
Stepper motors with encoders
The encoder continuously tracks the shaft position. The driver compares it with the commanded position and corrects deviations within the drive's capabilities, preventing missed steps from accumulating into positioning errors.
If an obstruction or overload prevents motion and the error exceeds the allowed threshold, the drive protection activates and motion stops.
Position feedback and protection against positioning errors.
/02Flow control
Flow control
Attention to detail
Extrusion and retraction are central to improving pellet printing quality.
Retraction and travel moves
between sections of the model
In industrial pellet extruders, melt pressure makes retraction difficult: pressure must drop quickly to stop the flow and be restored precisely before printing resumes. Simply stopping the screw does not always stop material from oozing out of the nozzle.
Controlling residual flow affects oozing, stringing between features, and clean starts on new sections.
An extruder designed from the ground up
We developed the FGF PRO extruder and its main assemblies ourselves. The design is based on our own engineering solutions, created specifically for pellet 3D printing. Flow control and retraction were part of the development from the outset.

Nozzles for your application
Standard E3D nozzles with an M6 thread. Diameters from 0.4 to 3 mm to suit the required detail and throughput.
Making your own nozzles
The required diameter can be obtained by drilling out the outlet of a standard brass E3D nozzle with a suitable drill bit. Afterwards, remove all burrs and chips and enter the new diameter in the slicer.

Part geometry, surface finish, and working with different materials.
Material experiments
Pellet printing makes it possible to try your own material formulations. The video shows an experiment printing a vase with wood shavings added to PLA.
In these trials, we assess how the mixture feeds, how it prints and the resulting surface texture. Each formulation and set of settings needs its own testing: one successful experiment does not mean that every mixture will print in the same way.

Built for different scales
Pellet printing is used in equipment of different sizes. When choosing a system, consider part dimensions, materials, required quality, and workflow.
Desktop systems
Material development, prototyping, and part production in a laboratory, workshop, or small manufacturing facility.
Industrial machines
Manufacturing applications with requirements for build volume, printing conditions, and integration into industrial workflows.
Large-format systems

Our approachThe possibilities of pellet printing
The possibilities of pellet printing
in a desktop format
We are developing FGF PRO to combine the possibilities of pellet feedstock with print quality close to FDM filament 3D printing.
Working directly with pellets provides access to industrial polymers, soft elastomers, and filled formulations, expands material choice, and can reduce feedstock costs.
Our goal is to make pellet 3D printing significantly more affordable and accessible to small manufacturers, workshops, researchers and independent developers. With affordable equipment, clear settings and practical examples, we aim to help more people use the technology.
