Who is large format FDM technology for?

⚙️ Engineering & design offices

The problem: you need to know whether a large part can be printed as it is, in which material and with what finish, before presenting it at a design review.
Our answer: a feasibility review of your STEP or STL file: orientation, any splitting, material and finish, followed by a full-scale large format prototype.

🏭 Industrial buyers

The problem: comparing “large format” offers that do not mean the same thing: real build volume, number of pieces, finishing included or not.
Our answer: a quote that states the volume printed in a single piece, the material, the finishes and the production lead time set according to size and complexity — see industrial large format 3D printing.

🎨 Creative agencies

The problem: a giant object for a campaign or a shop window, but no idea what the machine can render: details, colours, surface appearance.
Our answer: we turn the visual into a printable part, modelled from a photo or a sketch, then sanded and painted in the brand colours — examples in 3D POS displays.

📐 Architects

The problem: a bulky model to produce from BIM, with no model maker available and without cutting it into dozens of pieces.
Our answer: a model FDM-printed from your 3D export, in a single piece as long as it fits within the machine volume — see architectural models from BIM.

How does FDM 3D printing (fused filament fabrication) work?

3D printing is additive manufacturing: instead of removing material from a block, material is added only where it is needed. In FDM (Fused Deposition Modeling, also called FFF or fused filament fabrication), a spool of plastic filament feeds a print head; the filament is melted in a heated nozzle, then laid down in fine beads that cool and bond together.

Slicing software cuts the 3D file into thousands of horizontal layers. The machine draws each layer, the build plate moves down (or the head moves up), and the next layer fuses with the previous one: the part is built layer by layer, with no mould and no tooling.

The issue: a desktop printer quickly hits its size limit, and scaling up piece by piece multiplies glue joints and refinishing.
The PAMI3D solution: large format FDM machines and settings tuned for big parts — layer height, infill and number of walls chosen according to the expected finish and the use. It is the foundation of our large format 3D printing.

110×110×170 cm in a single piece: what large format changes

The issue: many so-called “large format” parts are in fact assemblies of small elements. Every joint is a weak point, a visible line and one more area to refinish.
The PAMI3D solution: our build volume reaches 110×110×170 cm in a single piece — a part as tall as a person, with no joint and no gluing. Beyond that, the part is split into calculated sections (tenons, dowels, structural bonding or fasteners), then the joints are refinished by sanding, priming and painting.

The cutting plan is approved with you before printing starts. That is how we produce full-scale form-validation models, industrial parts and museum replicas that exceed the machine volume.

Layers, surface finish and materials: what you get with FDM

Layer height sets the balance between fineness and print time: thin layers for details and curved surfaces, thicker layers for large, simple volumes. As printed, an FDM part shows slight horizontal lines; they disappear with sanding and priming. We print FDM polymers only:

  • PLA: detailed shapes, decor, models, indoor POS displays — a bio-based plastic (see bioplastic 3D printing);
  • PETG: parts that are handled or on display, signs, translucent versions that diffuse backlighting;
  • TPU: flexible parts, seals, protective parts, elements that need to bend;
  • ABS: prototypes and technical parts intended to be sanded and painted;
  • Nylon PA12: functional parts and tooling that withstand loads.
Our advice: describe the use (indoors, outdoors, handling, display): the recommended material is stated in the quote.

From 3D file to finished part: preparation and finishing

The issue: a file designed for the screen is not necessarily printable — open surfaces, walls too thin, scale to revise — and a raw print is not presentable in a shop window.
The PAMI3D solution: we accept STEP, STL and OBJ files, check and repair the mesh, and choose the orientation that minimises supports. No file? We model from a photo, a sketch or a drawing, or start from a 3D scan of the existing object. Details on our large format 3D files page.

For finishing: sanding, priming, painting in your brand colours, varnish. Gold, silver or mirror-like effects are achieved with tinted filament or a paint finish, on a part that stays light and entirely made of FDM plastic — see our 3D print finishing. The same technology is also used to print moulds for 3D thermoforming.

The limits of large format FDM, stated plainly

Choosing a technology also means knowing what it does not do. Here is what we will tell you before we even quote.

No optical transparency: translucent PETG diffuses light for backlighting, but an FDM part does not replace glazing or a lens.
Visible layers when raw: a smooth finish requires sanding, priming and painting — a finishing step to plan into the project.
Supports under overhangs: overhanging areas are printed on supports that are removed afterwards and leave marks to refinish.
Strength depends on orientation: the bond between layers is the weak point, so the print orientation is chosen according to the loads the part will carry.
Micro-details less crisp than at large scale: FDM excels at volume, less so at jewellery-scale or watch-scale details.
What it does very well: large, light parts in a single piece, with no mould, from a one-off to a short run, for prototyping, decoration or architecture. Regulated use or exposure to heat? We validate the material with you before production.

Large format 3D printing technology: your questions

How does FDM 3D printing work?

A plastic filament is melted in a heated nozzle and laid down in beads, layer after layer, following the path calculated from the 3D file. Each layer bonds to the previous one until the part is formed, with no mould and no tooling.

What is the maximum size of a large format FDM part?

Up to 110×110×170 cm in a single piece in our workshop. Beyond that, the part is cut into sections that slot together and are assembled, then the joints are refinished.

Which layer height and surface finish should I expect?

The layer height is chosen for each part: fine for details, thicker for large, simple volumes. Raw, the part shows slight lines; sanding, priming and painting give a smooth surface ready for display.

Which materials do you use for FDM?

FDM plastics only: PLA, PETG, TPU, ABS and Nylon PA12. The material is chosen according to the use — decor, handled part, outdoor, flexible or functional part — and stated in the quote.

Which files should I provide? And if I have none?

STEP, STL and OBJ files are accepted. Without a file, a photo, a sketch, a drawing or an existing object is enough: we model the part or start from a 3D scan. More details on our large format 3D files page.

What is the production lead time?

It is set in the quote according to the size and complexity of the part: a simple object is not scheduled like a painted assembly. Send your project to devis@pami3d.com: free quote within 24 to 48 hours, no obligation.

Why entrust your large format FDM project to PAMI3D?

Large format in a single piece

Up to 110×110×170 cm with no joint and no gluing: person-sized parts that are stronger and easier to finish.

A service provider, not a machine seller

You buy a finished part, not a printer: no investment, no training, no maintenance on your side.

Honest technical advice

Feasibility, material, orientation and the limits of FDM explained before the quote, to avoid unpleasant surprises.

One-off or short run

With no mould or tooling, from a single copy to a short run; the file is kept so the part can be reissued identically.

Finishing included

Sanding, priming, painting, varnish, gold or silver effects: the part comes out ready to display, install or test.
