Fused Deposition Modeling (FDM)

Parts On Demand


What Is Fused Deposition Modeling?

FDM (Fused Deposition Modeling) offers 3D printing’s unparalleled design freedom and fast lead times coupled with strong thermoplastics.

FDM Part Strength

FDM utilizes strong, engineering-grade materials like ABS, Polycarbonate and ULTEM™ 9085 Resin.

FDM can create production parts and functional prototypes with outstanding thermal and chemical resistance and excellent strength-to-weight ratios.

FDM from the Pioneers of 3D Printing

Being a part of the family that invented FDM technology means we’re backed by Stratasys’ strong commitment to R&D.

Our in-house FDM experts are constantly exploring new applications and possibilities alongside the Stratasys team.

FDM's Big Impact with Small Production Runs

FDM helps companies say yes to more opportunities in low-volume, customized production parts.


How Does FDM Work?

FDM technology allows you to use engineering-grade thermoplastics that are ready for harsh environments, tough testing, and demanding applications.

Use the same strong, stable plastics you’re familiar with to build geometries only attainable with 3D printing.

Engineer-Grade Thermoplastics with FDM

A wide-range of industry specific thermoplastics will help you achieve specific characteristics.

Projects in the industrial, heavy machinery and transportation industries utilize PC-ABS for its superior strength, and aerospace engineers favor ULTEM™ 9085 Resin and ULTEM™ 1010 Resin for their FST ratings and FAA 25.853 compliance.

Some materials feature biocompatibility and MRI transparency for medical applications.




Sparse vs. Solid Fill

One unique function of FDM 3D printers is a build mode that allows users to fill in thicker sections of the part geometry with what’s called “sparse fill.”

Sparse fill is when plastic is extruded in a scaffolding construction instead of a standard 3D printed layer. Solid fill is when the interior sections of the geometry have no air-gap between raster (the interior fill).

This results in sections of a 3D part being nearly hollow, but with the support needed to retain strength and rigidity. The exterior of either solid or sparse looks the same, while the sparse version greatly reduces the weight when compared to its solid counterpart.

Sparse-filled parts can be finished with the same post processes as solid-filled parts with the same processes as solid-filled parts (such as epoxy, primer, and paint).

Reduced Weight

Sparse fill means less material built into the part, so the weight of the final part is significantly reduced.

Reduced Build Time

Because the 3D printer has less plastic to lay down in each layer, a part that utilizes sparse fill takes less time to build, reducing delivery time.

Reduced Part Cost

Additionally, the reduction in material used to build spare fill parts and faster print time contributes to a cheaper overall part.

Frequently Asked Questions About Fused Deposition Modeling

Are FDM parts as strong as components built using traditional manufacturing methods?

The orientation of a printed part on the build platform has an effect on its strength. Parts are stronger along the X- and Y-axis of the build than the Z-axis.

What level of detail can be obtained with FDM?

FDM is available in several resolutions. At its highest resolution, the layer thickness is 0.005” and the X/Y resolution is 0.024”.

Can inserts be staked or added during an FDM build?

Washers, nuts, bolts, threaded rods, or other objects can be inserted mid-build by technicians without secondary operations.
