FDM - Fused Deposition Modeling
Fused Deposition Modeling (FDM) is a 3D printing process that creates three-dimensional objects by depositing melted thermoplastic material layer by layer.
A plastic filament is heated and extruded through a moving nozzle, which shapes the material according to the digital model.
FDM is a versatile, cost-effective, and widely adopted technology that supports a broad range of thermoplastic materials, allowing for the selection of different types with varying mechanical, aesthetic, and functional properties.
It is an ideal solution for prototyping and low-volume production.

PRINTABLE MATERIALS
PLA
PLA (Polylactic Acid) is a lactic acid–based polymer commonly used in rapid prototyping through FDM technology, thanks to its unique chemical and physical properties. It melts at around 180°C and offers mechanical performance between that of PET and polystyrene. PLA is biodegradable through hydrolysis when exposed to temperatures above 60°C and humidity levels exceeding 20%.
ABS
Acrylonitrile butadiene styrene (ABS) is a common thermoplastic polymer used to produce lightweight and rigid objects, as well as enclosures for electrical and electronic component assemblies. ABS is a copolymer derived from the polymerization of styrene and acrylonitrile in the presence of polybutadiene, which makes it a terpolymer. The composition typically ranges from 15% to 35% acrylonitrile, 5% to 30% butadiene, and 40% to 60% styrene. Fine ABS plastic granules—smaller than one micrometer—are also used in tattoo inks due to their particularly vivid coloration.
ULTEM
Polyetherimide (PEI) is a high-performance amorphous engineering polymer introduced in 1982. It is commercially known under the brand name Ultem. The stability of the imide bonds gives this material excellent heat resistance, dimensional stability, and high rigidity. The linkage between phenyl rings provides the necessary degree of chain flexibility required for good melt processability and favorable rheological behavior. This material also exhibits strong electrical insulation properties, stable across a wide range of temperatures and frequencies.
