FDM 3D Printing Capabilities

Fused Deposition Modeling (FDM) is a 3D printing technology widely known for its great material selection, accuracy, possibility to print large parts, and competitive cost. FDM parts are great for end-use, low-volume production, for rapid prototyping. FDM 3D prints usually do not require any post-processing.

Try Xometry Out Now In Just A Few Steps

Upload your CAD files

Multiple designs for different parts can be imported at the same time to produce a single quote. In less than a minute, a detailed cost estimation appears on the screen.

Choose the process

First, select the manufacturing process you require. You can then choose from over 70 materials, both metals and plastics, and from a wide range of finishes and certifications.

Order your parts online

Once you have selected the required options, all you need to do is confirm the order and pay for it on the secure payment platform. Your design will be analysed by engineers.

Receive your parts

Within a short amount of time, you will receive the parts you ordered directly to your shipping address. You can track your package at any time in your personal account.

Finishing Options for FDM 3D Printing

As-printed

FDM parts are built with support material that is removed during post-processing.
Final result:
- The part surfaces are left with fine layer lines
Custom

If you select a custom finish in the Instant Quoting Engine it will require manual review. Manual quoting usually 1-2 business days.

Notes:

Submitting for manual review with a custom request does not guarantee a quote.

FDM Infill Options

Fused Deposition Modeling (FDM) is a 3D printing technology that builds a part layer by layer by depositing heated thermoplastic along an extrusion path. In this process, there are several different ways the interior areas of a part can be interpreted when the part is built. Infill describes how those interior areas of a part should be filled in.

Xometry offers three types of infill options:

Ultralight FDM infill: Up to 20% infill density. Ultralight infill parts are filled with a single zig-zag pattern. This is the lightest and least expensive infill option
Light FDM infill: 20-50% infill density. Light infill parts are filled with a double cross-hatch pattern. This option provides increased rigidity and is lighter than a complete solid infill
Solid FDM infill: 50-80% infill density. Solid infill parts are filled for a higher density. This is the heaviest and more expensive option but offers the highest strength

FDM Layer Thickness Options

Layer thickness refers to the height of each layer added during the additive manufacturing or 3D printing procedure, where multiple layers are stacked upon one another to create the final product. For FDM, choosing your layer thickness is a critical parameter that directly impacts a part’s visual appearance, properties and printing time.

Xometry offers three layer thicknesses:

100 µm (Fine)
200 µm (Standard)
300 µm (Economy)

Pros & Cons of FDM 3D Printing

Advantages	Considerations
Large platform: you can print very large parts using this technology	Needs support elements, which can leave undesired marks after removing them
A very wide selection of materials and colours: over 40	Sweats small details
Usually do not require any post-processing	Significant layer stepping
Fast: Xometry can deliver them in just 8 days	Limited scalability
Cheap: for non-complex geometries this option might be around 15% cheaper than SLS
