Overview

What is Fused Deposition Modeling (FDM)?

Fused Deposition Modeling (FDM), also known as fused filament fabrication (FFF), builds parts by extruding thermoplastic filament through a heated nozzle and depositing it layer by layer.

FDM is commonly used for early-stage prototypes, dimensional and assembly checks, custom fixtures, and selected functional parts. Its practical advantages include a broad range of filament materials and the ability to produce useful components without conventional molds or machining setups.

Fused Deposition Modeling (FDM) Capabilities

FDM can be suitable for larger components, subject to the available build volume. Parts larger than the build area may require segmentation and assembly.

Build Size

  • Review part orientation against the main load direction.
  • Flag surfaces that need to stay clear of supports.
  • Allow for fit checks at mating features.
  • Confirm the filament and finishing route for the intended use.

Surface Finish Options

The interlayer bonding of FDM parts can affect strength and anisotropic performance. For parts subjected to loads, repeated bending, high temperatures, or precision fits, the material grade, printing direction, and testing requirements should be clearly defined.

Typical Order Volume Prototypes, selected low-volume parts, and custom fixtures

The Process

How Does Fused Deposition Modeling (FDM) Work?

FDM parts are built layer by layer, so build orientation and layer direction can affect strength, surface quality, and dimensional accuracy. Support structures, overhangs, warping, and visible layer lines should be considered during design.

The advantages

  • Cost-Conscious Prototyping:• A practical option for early design evaluation when a mold is not yet justified.
  • Large-Part Potential:• Suitable for selected larger prototypes, subject to the available build envelope.
  • Thermoplastic Options:• Material choices can be matched to different prototype and workshop needs.

The challenges

  • Custom Jigs and Fixtures:• Useful for selected assembly aids, positioning fixtures, and workshop tools.
  • Practical Functional Parts:• Supports fit, assembly, and selected functional tests when the material is appropriate.
