WHAT IS FDM 3D PRINTING
Fused deposition modelling, layer by layer.
The FDM 3D printing (Fused Deposition Modeling, also known as FFF / Fused Filament Fabrication) is the most widespread additive manufacturing technology in the world. It works by melting a thermoplastic filament through a heated nozzle, between 180 °C and 320 °C depending on the material, depositing it layer by layer onto a heated print bed until the complete part is formed.
It is the technology that has popularised 3D printing because it combines low cost, wide variety of materials and large print volumes. That is why it is the default option for functional prototypes, mechanical parts, tooling, supports, enclosures and short runs that do not require a perfect surface finish.
At Imprimakers we work with industrial-grade FDM printers and we maintain a fleet of more than 12 machines running in parallel to guarantee lead times of 24 to 72 h even for large orders.

HOW FDM PRINTING WORKS
The FDM 3D printing process, step by step.
From the CAD file to the finished part in your hands. A fully traceable process that we control in our workshop to guarantee consistent tolerances and finishes.
STEP 01 · SLICING
CAD file preparation
Your STL/STEP is processed in a slicer. We define orientation, infill, supports and print profile according to the final use of the part.
STEP 02 · HEATING
Filament loading and preheating
The hot-end reaches the melting temperature of the material (200 °C for PLA, 250 °C for ABS, up to 320 °C for PC and nylon). The heated print bed prevents warping on large parts.
STEP 03 · PRINTING
Layer-by-layer deposition
The nozzle moves in XY while the platform descends in Z. Each layer adheres to the previous one by thermal fusion, forming the part from the bottom up.
STEP 04 · SHIPPING
Support removal, QA and shipping
We remove supports by hand or by dissolution (PVA/HIPS), inspect critical tolerances with callipers and ship throughout Spain and Europe in 24 to 72 h.
ADVANTAGES AND LIMITATIONS
Why choose FDM... and when it is not the best option.
Like any technology, FDM has clear strengths and real limitations. Knowing them helps you decide if it is the right technology for your project.
Advantages Pros
-
The lowest cost per partThe most economical option on the market, especially for large volumes and simple geometries.
-
Greater variety of materialsFrom decorative PLA to carbon fibre composites or technical flame-retardant, ESD and high-temperature materials.
-
Large print volumesParts up to 500×500×500 mm in a single run, or much larger modular assemblies.
-
Rapid productionAn average of 3 working days from order confirmation. No moulds, no minimums.
-
Robust and functional partsSufficient mechanical resistance for tooling, prototypes subjected to stress and end-use parts.
-
Safe and clean materialsPLA and PETG are harmless in use. No liquid resins, no fine powders in suspension.
Limitations Cons
-
Lower surface finishThe staircase effect between layers is visible. For mirror surfaces you need sanding or acetone vapour (ABS).
-
Limited fine detailsBelow 0.8 mm wall or details < 0.4 mm quality drops. For jewellery or miniatures, SLA is better.
-
Mechanical anisotropyParts are weaker on the Z axis (between layers). They must be oriented correctly so the load does not separate the layers.
-
Requires supportsFor overhangs > 45° support material is needed, which leaves a mark when removed.
-
Wide tolerances±0.3 mm or 0.3 % typical. For h7/H7 mechanical fits, SLS or post-machining is better.
-
Very complex geometriesClosed interiors with complicated cavities are inaccessible. For those, SLS needs no supports.

Trustindex verifica que la fuente original de la reseña sea Google.estaba un poco escéptica después de leer alguna de las reviews. la verdad es que no tengo quejas. me puse en contacto con ellos y me respondieron con rapidez, diciéndome para qué día estaría listo. en mi caso, pedí una impresión pequeña en nylon para reparar una pieza de una cámara. la impresión tardó unos 10 días, después de que entrase en proceso de producción + la entrega al día siguiente. todo ha ido muy bien y la pieza encaja perfectamente en la cámara y con el tornillo que tenía pensando. recomiendo el servicio!

Trustindex verifica que la fuente original de la reseña sea Google.Muy profesionales. Les mandé un diseño 3d totalmente generado por inteligencia artificial (con las múltiples inconsistencias e inconvenientes que eso puede suponer) pero aún así han sido capaces de enviarme el pedido con un impresionante resultado final. Muy satisfecho con el proceso, y la atención recibida, sin duda los recomendaría y volvería a trabajar con ellos para futuros proyectos.

FREQUENTLY ASKED QUESTIONS
FAQ about FDM 3D printing.
The most common questions we receive about our FDM 3D printing service.
Still have questions?
info@imprimakers.com →
What is the difference between FDM and FFF?
Technically are the same technology. FDM (Fused Deposition Modeling) is a registered trademark of Stratasys, while FFF (Fused Filament Fabrication) is the generic term used by the rest of the industry. In practice, all filament printers use exactly the same principle: extruding molten thermoplastic layer by layer.
How much does it cost to print a part in FDM?
A small part in PLA (50 g) costs from 5 a 9 €. A functional enclosure in ABS (200 g) is around 40 €. A Nylon jig (400 g) is around €80. The price is calculated per gram (depending on material) plus print time. Our online calculator gives you the price instantly.
What is the maximum size you can print in FDM?
500×500×500 mm in a single part with our standard printers. For larger parts we split them into modules and assemble them in the workshop with structural bonding, with no visible joint. We have produced final parts over 1.5 m long using this system.
What FDM material should I choose for my part?
Depends on use: PLA for visual, decoration or parts not subjected to heat (warping at 60 °C). PETG for functional parts with some flexing or food contact. ABS/ASA for technical parts resistant to heat and weathering (ASA). NYLON for gears, joints or parts that rub. PA-CF for industrial tooling. If in doubt, write to us with a photo of the final use and we will recommend the optimal material free of charge.
How long does an FDM print take?
Print time varies a lot: a small part takes 30 min, a medium one 4 to 6 h, a large one can exceed 24 h. Our lead time is an average of 3 business days from the moment you confirm the order, thanks to a fleet of more than 25 FDM printers running in parallel.
Is FDM printing resistant?
Yes, especially with technical materials. A well-designed part in NYLON or ABS perfectly withstands mechanical use, vibrations and load. The key is orient it correctly: FDM parts are weaker on the Z axis (between layers), so the main load must run parallel to the layers. We help optimise the orientation for each order.
Can I print parts for outdoor use?
Yes, but choose the right material: PLA cannot withstand prolonged direct sunlight (it degrades under UV). For outdoors use ASA (the best option, UV and weather resistant), PETG (lasts several years) or PC (high resistance). For marine environments, NYLON.
What files do you accept for FDM printing?
We accept STL, STEP, STP, IGES, IGS, OBJ, ZIP up to 200 MB per file. STL is the most common format. If you only have an idea, a sketch or a physical object you want to reproduce, we also offer a 3D modelling service from €25/h.
Do you do NDAs / confidentiality agreements?
Yes, at no cost. Request it in the first message and we will send you the signed confidentiality clause before you send us the files. Your models are deleted when the project is closed if you request it. We work with several R&D companies under this model.
