When components are too large, too individual, or too time-critical for conventional methods, Large Format FDM quickly delivers a load-bearing result: prototype, fixture, or functional end part.
For construction, mechanical engineering, tooling, and bespoke solutions.
The short answer
Large Format FDM manufactures components up to 900 × 900 × 1000 mm in one piece: full-scale prototypes, fixtures, housings and large-volume spare parts – without tooling costs and without gluing multiple parts together. The best way to start is with a pilot part rather than striving for perfection.
Why large format?
Large parts are often expensive in traditional manufacturing because you quickly run into mould making, long CNC machining times or welded constructions.
Large-format 3D printing is of interest if you:
- want to quickly test in original size (fit, assembly, installation space)
- want to avoid tooling costs (one-off part, pre-production, small batch)
- you want to build components in one piece instead of segmented
- you need variants (special-purpose machine, retrofit, customer-specific)
The best way to start: pilot episode instead of perfection
Many projects don’t fail because of pressure – but because of false expectations.
That is why the neat way is often:
- pilot part (functional) → Check fit, stability, assembly
- Optimisation → Ribs, wall thicknesses, fixings, weight
- repeatability → parameter, post-processing, inspection plan
This is quicker, cheaper and leads to a reliable result more often than „everything perfect straight away“.
Large Format FDM is an industrial 3D printing process that builds large-scale plastic components layer by layer using fused deposition modelling.
Large Format FDM is an industrial extrusion process in which thermoplastics are built up layer by layer – with a significantly larger build volume than classical FDM, extending into the metre range.
Data box: Technical characteristics (LF-FDM)
- Installation space 1000 × 1000 × 1000 mm
- Materials ASA GF, PA12 GF, PA6 GF, PA6 CF, PP GF, TPU
- Costs approx. €0.08 – €0.35 per cm³ (depending on geometry/density/material)
- Accuracy approx. ±0.3 – ±0.8 mm (fit for purpose for large format)
Note: If you need very tight tolerances on individual surfaces, we often solve that through design plus defined rework – instead of forcing the whole component to be precision-made.
Typical applications
full-scale large-format prototypes
If you want to check geometry, ergonomics, assembly or installation space in reality – without tooling and without long lead times.
Operating resources, gauges and fixtures
Assembly fixtures, positioning aids, drilling templates, test gauges or handling aids – quickly available and individually customised.
Enclosures, covers & structural components
Cladding, covers, functional parts for special-purpose machinery and plant – including integrated mounting points, channels, ribs.
Spare parts & reproductions (high-volume)
When components are obsolete or urgently needed – without warehousing and without tooling costs.
Large-format TPU (flexible & shock-absorbing)
Protective components, mounts, damping elements – when flexibility, impact resistance or vibration damping matters.
Material selection in large format
In large format, material determines not just „strength“, but dimensional stability and suitability for application.
- ASA GF: weather-resistant, dimensionally stable (outdoor/environmental impact)
- PA12 GF dimensionally stable, chemically resistant (functional components)
- PA6 GF / PA6 CF: high-strength, structurally robust (rigid, load-bearing)
- PP GF: lightweight, chemical-resistant (special environments)
- TPU: flexible, impact-resistant, shock-absorbing (protection/damping)
Tell us the location and load profile → we will recommend the material and wall thicknesses/ribbing.
Borders
Large format is powerful – but not for everything.
Typical boundaries that we clarify early:
- Surface „perfectly smooth“ needs finishing/planning
- Tolerances: large-format = fit for purpose; precision pinpointed
- Delay: Determine geometry and ribs/wall thicknesses
- Weight/Handling: Deliberately choose component density (not „massive“)
The good thing: if you bring it up early, it's not a problem – it's just planning.
This is how a large-format project runs
- Input: STEP/drawing or photo + dimensions + application description
- Quick check: Feasibility, materials, orientation, risks
- Pilot section (if appropriate): Test at original size
- Final: Optimisation, post-processing where necessary, delivery
Conclusion
Large-format 3D printing is worthwhile when components are too large, too bespoke or too time-critical for traditional methods. A pilot part quickly shows whether geometry, material and function are right before series production or the final part follows. The limitations lie in surface finish and tolerance, not size. Price and feasibility for your component are shown by the 3D printing calculator.
Request large format
Send us your component and briefly tell us what it needs to be able to do. You'll receive a well-founded assessment regarding geometry, material and feasibility – and, where appropriate, we'll start with a pilot part.
