3D printing for architects: custom models and prototypes

A scale model says at a glance what a drawing takes ten minutes to explain. For an architect, it is a tool of persuasion as much as of design. 3D printing has transformed how it is made: what once took days of cutting and gluing is now produced from your file, with consistent precision.

Here is concretely what it brings to your work, and how we approach it in the workshop.

Why print your models in 3D

The handmade model has its charm, but it has a cost: time, a lot of it, and a consistency that is hard to hold on complex shapes. 3D printing answers three needs specific to the profession:

• Speed. Once the file is ready, the model is made without tying up your teams for hours.
• Precision. Proportions are respected to a tenth of a millimetre. A grid, a façade rhythm, a cantilever: everything is faithful to the project.
• Iteration. Project evolving? We reprint the relevant version without redoing everything. The model keeps pace with the design.

The deliverables we produce

An architect's need is never single. Depending on the project phase:

• Competition model: overall massing, insertion into the site, immediate readability of the concept.
• Client presentation model: finer, polished, sometimes in separable levels to show the interior.
• Detail prototype: a fragment of façade, a window frame, a constructive system at scale, to validate an intent before defending it.
• Urban elements: street furniture, roads, the topography of a district.

FDM or resin: a technology for each part

We combine both families depending on the expected result:

• FDM for volumes and large format. Our machines print up to around 25 cm per part; beyond that, we assemble several modules to produce large models. It is also the most economical solution for masses.
• Resin for fine detail: railings, mullions, window frames, street furniture, decorative elements. Where FDM reaches its limit of fineness, resin takes over.

A single model often mixes both: the body of the buildings in FDM, the details in resin. To understand the trade-offs, see our article on FDM or resin, and our materials page for finishing options.

From raw to presentable: finishes

A model does not always need to be painted. Three levels depending on use:

• Raw: monochrome, for a working model or a study volume.
• Sanded: smoothed surfaces, for a cleaner result.
• Painted: colour, material contrasts, for a client presentation or a competition.

We advise the right level: no need to paint a study model, essential to polish a submission model.

From file to result

Already working in 3D? We start from your digital model (CAD files or 3D model) and prepare it for printing. Only have a drawing or an intent? Our CAD design service models the elements for you.

In both cases, we review the geometry, choose the orientation and the splitting into modules, and launch production. All of it as rapid prototyping when a competition imposes a tight deadline.

Confidentiality, by default

An architecture project is sensitive, especially in the competition phase. Your files and models remain confidential. We share no project without your explicit agreement.

A competition to submit, a presentation to prepare? Tell us about the project or start an online estimate. We calibrate technology, scale, splitting and finish to the deadline and the desired effect.

Frequently asked questions

What model size can you print?

Each part goes up to around 25 cm per side. For a large model, we print it in several modules that we assemble — so there is no practical limit to the final size.

What file do you work from?

A 3D model from your architecture software, or a CAD file. If you only have a drawing or a sketch, we model the elements for you.

How long for a model?

It depends on the size, the number of modules and the finish. For a competition with a tight deadline, we work in rapid prototyping — tell us the deadline and we calibrate.

Do my projects stay confidential?

Yes. Your files and models are confidential and are never shared without your agreement.
