FDM Prototyping

Fused Deposition Modelling

Prototype Projects offers Fused Deposition Modelling (FDM) prototyping for low cost production of small numbers of strong, durable prototype parts, jigs and fixture assemblies from ASA plastic.

What are FDM parts used for?

FDM parts can be used as early concept prototypes, to validate design and for functional testing of specific properties e.g. heat resistance, durability and strength.

Prototype Projects in-house FDM prototyping services

Prototype Projects uses the F170 3D Printer from Stratasys to produce fine detail 3D parts for both presentation and testing.

With the ability to print in ten colours of ASA thermoplastic, the F170 has a versatile range of resolutions depending on requirements from .127mm to .330mm layer thickness, making it ideal for presentation parts and functional parts including medical devices, electronic components and precision instruments.

FDM Prototyping Technical Details

      • Build size: 254 x 254 x 254 mm (10 x 10 x 10 in.)
      • Layer thickness: 0.330 mm (0.013 in.) or 0.127 mm (0.005 in.)

FDM Rapid Prototyping Process

FDM rapid prototyping is a 3D printing process used for building prototype parts made from layers of ASA plastic. The process normally includes the formation of a support structure which can be removed by hand on completion.

When to use FDM Prototyping

FDM parts can be produced to represent the strength, flexibility and durability properties of the final production part and are ideal for physical testing.

While mechanically ideal for evaluating design and functional testing, FDM models are not suitable for assessing the eventual manufacturing potential of the part or product.

FDM Process Benefits

FDM prototyping is a popular choice for product designers and engineers, particularly in the automotive industry, because of its:

  • Speed: FDM is ideal for production of ASA prototypes – depending on complexity, though is not as quick as SLA or SLS
  • Low cost: FDM is a relatively low cost process
  • Properties: the model produced closely reflects the properties of the final product for strength, heat resistance, UV stability and water resistance
  • Testing: Because of the above, FDM models are ideal for functional testing
  • Small runs: ideal for small runs of prototype parts for functional testing

FDM part properties

  • Heat resistance
  • Strength
  • Rigidity
  • Stability
  • Surface may be ridged

Fused Deposition Modelling Materials Offered

We offer ASA thermoplastic on the FDM machine. ASA is set to become the most popular all-purpose prototyping material. It matches or exceeds the mechanical properties of ABS and is UV resistant. As well as a wide range of colours available, it also offers a matte finish making it highly versatile.

Support structures are removed by hand.

FDM parts are not suitable for painting.
