Fused Deposition Modeling (FDM)


Fused Deposition Modeling

Durability That Lasts

Fused Deposition Modeling (FDM) utilizes a filament that’s heated in a nozzle and then extruded layer by layer until the part is fully built. FDM allows for printing with engineered plastics, producing very strong parts. This process is very slow though and can have medium to low surface finish. If needed, surfaces can be modified, post processed, and allow for minimum machining capabilities.

FDM is ideal for low volume end-use parts and prototypes.


Fused Deposition Modeling (FDM) Process

Step 1​

Energy is applied, material is extruded through heated nozzle.

Step 2​

One layer/cross-section is applied to the build platform.

Step 3​

Platform is lowered and next layer of material is fused to the previous layer. Process is repeated.

Step 4​

Completed part is then ready to remove from build plate.

Max Size Capabilities

FDM utilizes dual heads. One for support and the other for the plastic. Due to the nature of how supports are printed, orientation of your part is critical. When designing for FDM if you have any questions please provide them along with your quote.
