What is Fused Filament Fabrication?
Fused Filament Fabrication (FFF), otherwise known as 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 is a process that provides engineers and designers 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?
We take your CAD file and input it into the machine, and the software breaks it down layer by layer. We also take into consideration the direction of the build and the placement of the supports. The Fused Filament Fabrication machine uses a heated nozzle to extrude a filament onto a heated build platform. As the part is drawn, the nozzle moves up. This process is continual with no breaks in-between layers.
Once finished, the parts are manually removed from the platform, the supports are removed from the parts, and they’re ready to go to the finishing department.
What are the ideal applications for fused filament fabrication?
• Form, fit, and function testing for prototypes
• Low-volume production for complex end-use parts
