FDM

Fused Deposition Modelling

Fused Deposition Modelling (FDM) is a material-extrusion-based additive manufacturing process. Objects are built layer by layer, following a software-generated path. It is the primary 3D printing technology employed at the Fab Lab.

A solid, thermoplastic filament (most commonly ABS, PETG, and PLA) is heated to a melting point (usually between 180° and 220°, and fed through a small nozzle (most commonly 0.4mm in diameter).

The nozzle follows paths that are generated in slicing software (such as ). This software is also used to generate the necessary and to ensure that the object is printed accurately.

This is the primary method of 3D Printing employed at the FabLab.

Advantages of FDM

Disadvantages of FDM

  1. FDM is the most cost-effective way of producing custom thermoplastic parts and prototypes. 

  2. The lead times of FDM are short (as fast as next-day delivery), due to the high availability of the technology. 

  3. A wide range of thermoplastic materials are available, suitable for both prototyping and some non-commercial functional applications. 

  1. FDM has the lowest dimensional accuracy and resolution compared to other 3D printing technologies, so it is not suitable for parts with intricate details. 

  2. FDM parts are likely to have visible layer lines, so post-processing is required for a smooth finish. 

  3. The layer adhesion mechanism makes FDM parts inherently anisotropic.
