FDM 3D Printing Service

Manufacturing with FDM 3D printing

FDM (fused deposition modeling) 3D printing creates custom parts by heating and extruding thermoplastics layer-by-layer. You can use FDM for initial and functional prototyping and low volume production in a variety of strong plastic materials. While FDM is the most affordable 3D printing technology, it’s far more than a small-scale manufacturing solution. 3D printing with FDM means getting access to thermoplastics, including PLA, ABS, TPU, PETG and PEI, and a dimensional accuracy of ±0.5% with a lower limit of ±0.5 mm (0.0196”).

Fused Deposition Modeling (FDM) capabilities

FDM 3D printing has two distinct classes: prototyping (desktop) FDM and industrial FDM. These are the key capabilities of both technologies.

	Maximum build size	Standard lead time	Dimensional accuracy	Layer height	Infill
Prototyping FDM	500 x 500 x 500 mm (19.68 in x 19.68 in x 19.68 in)	From 2 business days	± 0.5% with a lower limit on ± 0.5 mm (0.0196 in)	100-300 μm	20-80%
Industrial FDM	406 x 355 x 406 mm* (15.98 x 13.97 x 15.98 in)	3 business days	± 0.25% with a lower limit: ± 0.25 mm (0.01 in)	100-300 μm	Ultra-light, Light, Solid

Why choose FDM?

We have high standards for FDM 3D printing

We manufacture your custom parts according to strict manufacturing standards and ensure all parts and processes adhere to the Hubs Standard. A thorough verification of these requirements is included in our inspection report that we ship with every order.

Consistent surface finish with no bumps or delamination. Marks left by retraction and layer changing are acceptable.
All support material is removed so that the supported surface has a consistent finish.
All parts are printed with 3 outline / perimeter shells or a wall thickness of 1.2 mm.

Advantages and drawbacks of FDM 3D printing

Advantages

FDM is the most cost-effective way to produce custom thermoplastic parts and prototypes.
Lead times are short (typically a few days).
A wide range of materials is available, suitable for prototyping and industrial applications.

Drawbacks

FDM is not suitable for parts with very small details due to its low resolution.
Parts are likely to have visible layer lines, so post-processing is required for a smooth finish.
The layer adhesion mechanism makes parts inherently anisotropic.
