Fused Deposition Modeling (FDM)
At a Glance
About the Process
Fused deposition modeling (FDM) is a 3D printing technology (also known as additive manufacturing) commonly used for modeling, prototyping, and production applications. Each layer is created by extruding material from a nozzle to produce 3D objects. At Shapefy, all FDM prints are produced according to the resolution chosen by the customer keeping a balance of accuracy and strength with speed.
FDM processes require support material, either breakaway or soluble, so it’s important to keep this in mind when choosing this process as it can affect the final part.

+ Design for Manufacturing Tips
- No internal cavities
- Limit curved surfaces
- Orientation on small holes is very important (xy plane is much more cylindrical)
- Bridging: distances of up to 10 mm do not necessarily need support material, as long as the area being printed has support on both sides of the material being laid down.
Cost Saving Tips
2. Reduce the amount of support material required by overhangs and special orientations.
3. Choose PLA for simple geometry parts and where tolerance is less important.
