Fused Deposition Modeling (FDM) is an additive manufacturing process that builds 3D objects by heating and extruding thermoplastic filament through a nozzle, layer-by-layer, onto a build platform. It is the most common and accessible 3D printing technology, often used for rapid prototyping, functional parts and lower quantity production.

​

Objects are built using thermoplastic filament heated to a liquid state and extruded through a nozzle, depositing material on a build platform according to a CAD model's toolpath. The object is built in layers with each layer bonding to the one below as it cools. Generally, FDM parts can have visible layer lines with strength of a given part dependent on print orientation - there's a general 'weakness' of layer line adhesion creating a 'fail point'.

​Common materials are:  PLA (easy to print), ABS (more durable), PETG (balanced) and TPU (flexible).

Ideal applications:

• Low to mid volume production (10's to 100's+ parts) of small to medium sized parts

• Low cost prototyping of initial concepts. Can be used as a low cost option prior to using more robust Stereolithographic (SLA) processes

• Relatively simple geometry and/or parts design with FDM principles
