What is Fused Filament Fabrication?
Fused Filament Fabrication (FFF), or Fused Deposition Modeling (FDM), is a thermoplastic filament that’s melted through a heated nozzle and selectively extruded, building layer upon layer.
An industry standard, fused filament fabrication 3D printing is a process that provides engineers and designers with numerous material options with the open-source machine platform. Durable, rigid, single-color parts with moderate detail are suitable for check fixtures, specialized tools, functional prototypes, and end-use parts.
How does Fused Filament Fabrication work?
An AM Technician takes your CAD file and uploads it into the machine, where the software breaks it down layer by layer. The AM Technician also considers the direction of the build and the placement of the supports. The Fused Filament Fabrication 3D printing machines use a heated nozzle to extrude a filament onto a heated build platform. As the nozzle “draws” the part, the nozzle moves up layer by layer. This process is continual with no breaks in-between layers.
Once finished, the AM Technician removes the parts from the platform and the supports from the components. Then the parts are ready to go to the finishing department.
Ideal applications for Fused Filament Fabrication?
Since Fused Filament 3D printers use production-grade materials, it’s a suitable technology for parts throughout the product development cycle, from prototypes to end-use components.

Key Characteristics
More Information
ABS-ESD7 is an ABS thermoplastic with static dissipative properties that are excellent for applications where a static charge can damage products, debilitate their performance, or cause an explosion.
- Black
- Impact Resistant
- Static Dissipative
- UV Stability
ABS-M30 has significantly stronger layer bonding than ABS and higher tensile, impact, and flexural strength. ABS-M30 parts are more durable, smoother, and have greater detail.
- Biocompatible*
- Impact Resistant
- Multi-color
- Rigid
- UV Stability
ASA is a thermoplastic that builds high-quality parts with excellent UV stability.
- Multi-Color
- High Strength
- UV Stability
PC-ABS combines the flexibility of ABS with PC’s strength and heat resistance.
- Black or White
- High Strength
- Impact Resistant
- Flexible
- Heat Resistant
PC-ISO is strong thermoplastic, heat resistant, and biocompatible (gamma and ETO sterilizable and complies with ISO 10993 and USP Class VI standards).
- White
- Biocompatible*
- Heat Resistant
- High Strength
Polycarbonate (PC) is a highly accurate, durable, and stable material creating strong thermoplastic parts.
- Biocompatible*
- Heat Resistant
- High Strength
- Impact Resistant
- Rigid
- UV Stability
Ultem 9085 resin is a flame-retardant, high-performance thermoplastic featuring a high strength-to-weight ratio, excellent heat resistance, and high impact strength.
- Chemical Resistant
- Flame Retardant
- Heat Resistant
- High Strength
- Impact Resistant
- Rigid
- UV Stability
Ultem 1010 resin possesses high heat resistance and thermal stability, one of the strongest thermoplastics. It is biocompatible and approved for food contact (NSF 51 and ISO 10993/USP Class VI certifications.
- Biocompatible*
- High Strength
