FDM 3D printing service for functional plastic parts
FDM, also known as FFF, builds plastic parts layer by layer from filament. The process suits many functional components, prototypes, enclosures, replacement parts and small batches when design, material and print orientation are matched to the task.

When FDM is useful
FDM is versatile for technical one-offs, larger geometries and repeatable small batches. It can support form and assembly checks early in development and later manufacture the same basic geometry as a working part.
Not every geometry prints without supports or finishing. Overhangs, cavities, thin webs and unfavourable load paths are reviewed before production.
Material, orientation and build volume
Material selection follows temperature, loads, flexibility, environment and surface requirements. A material name alone does not guarantee part properties; wall thickness, infill, orientation and geometry also affect the result.
A build volume up to approximately 80 × 40 × 60 cm is available for suitable FDM projects. Larger or difficult models can be assessed for segmentation.
Tolerances and surface
Visible layer lines are inherent to the process. Functional dimensions, holes, plug connections and mating parts need to be identified so orientation, machining allowance or a test part can be planned.
Binding tolerances are project-specific. Sanding, drilling, threaded inserts, priming or other finishing can be agreed separately depending on geometry and material.

Frequently asked questions
Are layer lines visible with FDM?
Yes. Their appearance depends on geometry, layer height, material and orientation. Finishing can be agreed for suitable parts.
Which filament is best?
There is no universally best material. Selection and the relevant data sheet must fit temperature, loads, environment and part design.
When should I choose SLA instead?
SLA can be more suitable for very fine details and high-quality surfaces. FDM is often advantageous for larger or functional plastic parts.
