Fused Deposition Modeling
FDM stands for Fused Deposition Modeling. The most popular type of 3D printing technology used to create physical objects by laying down melted thermoplastic filament layer by layer. A 3D printing process that extrudes thermoplastic filament through a heated nozzle to build parts layer by layer. FDM is more cost efficient compared to SLA and injection molding.
Applications:
Custom Parts: Ideal for creating custom or one-off parts like cable organizers, brackets, or ergonomic tools. Suitable for parts that require dimensional accuracy.
Functional Prototypes: Can be used for functional testing of parts before mass production.
Low-Cost Production: Suitable for prototypes, small production runs or educational purposes.
Materials:
PLA, ABS, PETG, Nylon, and more with various properties (strength, flexibility, heat resistance). Some filaments are infused with composites like carbon fiber or wood-fill.
Filament options:
| Material | Print Ease | Strength | Heat Resistance | Outdoor Use | Key Advantage |
|---|---|---|---|---|---|
| PETG | ⭐⭐⭐⭐ | ⭐⭐⭐ | ⭐⭐ | ⚠️ | Best balance of strength & ease |
| PLA | ⭐⭐⭐⭐⭐ | ⭐⭐ | ⭐ | ❌ | Easiest & most affordable |
| ABS | ⭐⭐ | ⭐⭐⭐ | ⭐⭐⭐ | ⚠️ | Tough & heat resistant |
| ASA | ⭐⭐ | ⭐⭐⭐ | ⭐⭐⭐⭐ | ✅ | UV & weather resistant |
| Nylon (PA) | ⭐ | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ | ⚠️ | Strong & wear resistant |
| Nylon CF | ⭐ | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | ⚠️ | Ultra-strong & rigid |
| TPU | ⭐⭐ | ⭐⭐⭐ | ⭐⭐ | ✅ | Flexible & impact resistant |
Pros:
- Relatively affordable and accessible
- Good for rapid prototyping and custom parts
- Wide material variety and easy post-processing (filing, painting)
Cons:
- Layer lines and surface finish can be visible
- Mechanical properties are anisotropic (x/y/z depending on layer bonding)
- Warping, stringing, and calibration challenges depending on design, dimensions and material to be used.
- Printing time can be a major factor depending on the printer and filament type
