Fused Deposition Modeling (FDM)
Fused deposition modeling, also known as fused filament fabrication, creates 3D printed plastic parts by extruding thermoplastic filaments in successive layers. FDM 3D printing provides high dimensional accuracy and consistency on every part. Because of the strength and durability of industrial thermoplastics like ABS, PC and Ultem, it is ideal for fixtures, stamping tools, mechanical prototypes, form-fit-function models and small-batch production.
3D printed plastics are durable, inexpensive and quick to produce. They also eliminate many of the design restrictions of traditional manufacturing. To learn more about our other 3D printed plastic options, check out our HP Multi Jet Fusion 3D printing services or our 5-Minute Buyer’s Guide.

FDM Design Guidelines
When using the data below, please keep in mind that FDM materials are orthotropic, not isotropic. As a result, FDM materials have different material properties for different directions.
Please note that these are are guidelines, not hard-and-fast rules. Follow these, and you should be in pretty good shape. We’ll let you know if we see any problems with your design.

*Build volume is up to 36 x 24 x 36 inches. Larger models can be manufactured in sections and assembled after printing.
**FDM allows for some of the highest 3DP tolerances for large parts due to geometric stability. Minimum tolerance is +/- 0.005 in.
