FDM printing for functional parts
Cost-effective printing for fixtures, housings, prototypes and small batches in engineering plastics.

- Functional parts and larger geometry
FDM builds a part layer by layer from molten thermoplastic. It offers a broad material selection and is especially useful for functional parts, larger geometry and recurring low-volume production. Design and orientation are chosen with the part's loads in mind.
Where FDM is most useful
Housings and brackets
Custom enclosures, supports and adapters with integrated mounting features.
Functional prototypes
Parts for fit, movement and basic load checks before final manufacture.
Design with layer direction in mind
An FDM part is usually strongest within a layer and weaker between layers. Build orientation therefore affects strength, appearance, supports and cost.
Typical tolerance is ±0.2 mm or ±0.1% (whichever is greater), but geometry, size and material affect the result. Mark critical fits; they may need machining or first-article testing.
- State the principal load direction
- Avoid unnecessarily thin walls and sharp overhangs
- Consider threaded inserts for frequently used screws
How we prepare an FDM part
- 01
Review requirements
We examine loads, environment, fits and desired finish.
- 02
Choose material and orientation
The part is oriented for a sensible balance of strength, finish and support area.
- 03
Print and inspect
Supports are removed and agreed dimensions or functions are checked.
Input for a functional FDM part
Clear operating requirements help us choose the plastic and build direction.
- 3D file and quantity
- Loads and load direction
- Critical dimensions and tolerances
- Temperature and UV exposure
- Chemical or moisture contact
- Threads or finishing requirements
FDM printing questions
How accurate is FDM printing?
Typical tolerance is ±0.2 mm or ±0.1%. Small holes, long flat surfaces and high-shrink materials may need special attention or finishing.
Which materials are available?
Common choices include PLA, PETG, ABS, ASA and flexible materials. The right choice depends on heat, UV, impact, chemicals and required stiffness.
Are FDM parts equally strong in every direction?
No. Bonding between layers means build orientation affects strength. Describe the load case so we can account for it.
Can FDM parts have threads?
Larger threads can be printed directly. Heat-set or other inserts are often better for repeated fastening or higher loads.
Can the part be used outdoors?
Yes, with a suitable material. ASA is often preferable to PLA under UV and weather exposure.
When should I choose SLA instead?
Choose SLA when very small details, smooth surfaces or fine lettering matter more than FDM's material range and economy.
