FDM 3D Printing
FDM is one of the most common 3D printing methods, building parts by depositing melted thermoplastic filament layer by layer.
Definition
FDM is an additive manufacturing method that pushes thermoplastic filament through a heated nozzle and deposits it layer by layer. In Fabberworks, FDM is a core 3D printing process for quick prototypes, visual models, fixtures, and low-volume functional parts.
Related Terms
- PLA: an easy-printing, low-cost FDM material used often for visual prototypes.
- STL: the most common mesh-based file format sent to FDM printing.
- DFM: manufacturability checks for wall thickness, support needs, tolerance, and orientation.
- RFQ: the quote flow where a customer submits files, quantity, material, and delivery expectations.
Common Uses
FDM fits early prototypes, product housings, jigs, fixtures, mockups, and low-risk end-use parts. It does not match SLA for fine detail, but its material range, speed, and cost profile make it one of the most accessible MVP processes.
Watchouts
Part orientation, support marks, layer lines, infill, and hole tolerances directly affect the result. For press-fit or close-fit parts, include the nominal dimension and the expected tolerance range in the request.
