PrintDomus: 3D Printed Architecture for Rapid Refugee Housing

PrintDomus is an affordable housing proposal that explores how 3D printed architecture can respond to one of the most urgent humanitarian challenges of the present: the need for fast, economical, dignified housing for displaced people and refugee communities. Designed by Elena Feruglio and Alberto Carminati, the project proposes a rational settlement model where construction technology, modular planning, and spatial dignity work together.

The project is based on a clear premise: 3D printing technology has reached a level of maturity where it can move beyond experimentation and become a practical tool for the next building revolution. In crisis conditions, where time, cost, material availability, and logistics are often unstable, PrintDomus offers a system that can be measured, deployed, expanded, reduced, and adapted with precision.

Rather than treating refugee housing as temporary shelter alone, PrintDomus imagines it as a complete neighborhood. The proposal includes 150 houses, water cisterns, green public areas, a school and public hall, a hospital and small store, and a guard and concierge house. This transforms the project from a collection of units into a planned community with services, infrastructure, and social space.

3D Printed Architecture as a Humanitarian Building Strategy

The main architectural value of PrintDomus lies in its use of 3D printed architecture as a tool for speed and predictability. In emergency housing, construction schedules are often affected by uncertain supply lines, limited labor, funding gaps, and changing site conditions. Conventional construction can struggle under these constraints because every delay affects material procurement, labor coordination, and overall cost.

PrintDomus addresses this problem through a controlled printing logic. The project allows time and material consumption to be evaluated through measurable data, especially the length of printing filament required for each housing unit. Once the filament length is known, other costs such as fixtures, systems, support components, and roof structures can be estimated more accurately.

This approach gives 3D printed construction a major advantage in humanitarian contexts. It enables rapid prototyping at full scale before deployment, supports modular replication, and gives planners the ability to adapt the settlement without redesigning the entire system. In uncertain crisis environments, this flexibility is not just technical. It becomes a social and logistical necessity.

A Rational Plan for 150 Housing Units

The masterplan organizes 150 houses across a site of approximately 15,700 square meters. The housing units are arranged through strip planning, where buildings are printed along linear zones compatible with commercial 3D printing systems. The settlement reaches an overall density of 44 percent while maintaining a solution density of 65 percent within the active built arrangement.

The planning strategy separates the project into 13 strips and 3 blocks, each with different shapes and colors. This block-based structure supports construction sequencing, unit allocation, maintenance, and future expansion. It also avoids the monotony often associated with large-scale emergency housing.

The central idea is not only to place units efficiently, but to preserve public and green spaces wherever possible. These open spaces improve the livability of the settlement and create room for collective activities, circulation, water infrastructure, and community services. In this sense, PrintDomus is not only a construction proposal. It is an urban design strategy for displacement.

Shape Selection and the Perimeter-to-Area Logic

A key design principle behind PrintDomus is the optimization of the perimeter-to-area ratio. In 3D printed architecture, the amount of material and time required for a unit is strongly linked to the length of the printed walls. A lower perimeter-to-area value means that a unit can enclose more usable space with less printed material, reducing cost and construction time.

The design studies different shapes, comparing their perimeter values, symmetry, furnishing potential, and print efficiency. A circular shape offers an efficient perimeter-to-area relationship, but a fully circular unit can create difficulties in interior arrangement and in connecting naturally with neighboring units. PrintDomus therefore uses a hybrid geometry that balances curved walls with straight edges.

This strategy allows the unit to benefit from the efficiency of curved forms while remaining practical for furniture placement, room division, and shared-wall configurations. The result is a housing form that is economical to print, easier to organize internally, and visually distinct within the settlement.

Unit Joining and Shared Walls

One of the strongest aspects of the project is the joining of units through shared walls. When two units are connected, the shared perimeter reduces the total length of printed wall required. This directly lowers both time and material consumption.

The same unit can be arranged in multiple orientations without changing its material, design, or cost requirements. This gives the settlement flexibility while keeping the construction system standardized. Different orientations create visual variety, improve privacy, and help each block develop a specific spatial character.

The use of shared walls also strengthens the project’s modular logic. Each block can be constructed independently, paused if needed, and resumed without disrupting the entire settlement. This is especially important in refugee housing contexts, where construction must often respond to unpredictable funding, urgent arrivals, and changing population needs.

Printing Process and Construction Sequence

The construction process is organized into clear steps. First, a concrete foundation is laid out along a strip, and the 3D printer is assembled. The first layer is then printed across the whole strip, establishing the footprint of the unit.

As printing continues, window height is reached and sill elements are placed without stopping the process. Gaps for windows and doors are later filled with support elements, allowing the printing operation to proceed efficiently. Once the printed shell is complete, fixtures are installed and a corrugated metal roof is placed over the unit.

The wall system uses different thicknesses for different purposes. External walls are shown as 30 centimeters thick, with two parallel filament lines and a wavy filler. Internal walls are thinner, at around 10 centimeters. The filament itself is represented as 5 centimeters wide and 2.5 centimeters thick. Systems such as electrical and hydraulic infrastructure are integrated into the construction logic, helping the printed shell become a functional home rather than only a structural object.

A single unit requires approximately 9,243.26 meters of filament. For 150 units, the project estimates about 1,386,489 meters of filament. With a printer speed of 0.15 meters per second, the total printing time is calculated at 106 days. For a settlement of this scale, this demonstrates the potential of 3D printed architecture to create large housing capacity within a compressed construction timeline.

Interior Design for Practical Living

PrintDomus focuses on simple, essential, durable, and affordable interiors. The individual unit includes an entrance with living and kitchen areas, two rooms, and one bathroom with toilet, shower, and sink. One room is designed with a double bed, while the other can accommodate a bunk bed, making the unit suitable for family use.

The furniture strategy is deliberately minimal. In refugee housing, excessive complexity can increase cost and slow down delivery. PrintDomus instead prioritizes functional domestic space, easy maintenance, and basic comfort. The curved geometry gives the unit a distinctive architectural identity while maintaining enough straight-wall logic for daily living.

The result is a home that avoids the dehumanizing effect of emergency accommodation. It provides privacy, basic services, and a sense of normal domestic structure. This is one of the project’s most important social contributions.

Community Infrastructure and Public Space

The settlement plan includes more than housing. Water cisterns are placed within the site to support essential infrastructure. A school and public hall provide space for education, gathering, and social support. A hospital and small store address health and daily needs. A guard and concierge house adds a layer of organization and safety.

Green public areas are distributed throughout the plan, preventing the settlement from becoming a purely mechanical grid of shelters. These spaces create relief, orientation, and human scale. They also help establish a more dignified environment where residents can move, meet, rest, and rebuild routines.

The project recognizes that refugee housing must be more than a response to physical displacement. It must support social stability. By integrating public functions and open areas, PrintDomus moves toward a more complete model of humanitarian architecture.

A Design That Can Expand or Contract

One of the most practical advantages of PrintDomus is its ability to adapt. Since every block and strip can be built independently, the settlement can grow in stages. If conditions change, the construction process can be halted, resumed, extended, or reduced without requiring major modifications to the entire system.

This flexibility is central to crisis architecture. Displacement scenarios are rarely predictable. Population numbers shift, resources fluctuate, and local conditions can change rapidly. PrintDomus responds through a modular framework that allows the project to remain functional even under uncertainty.

The use of 3D printed architecture also makes it possible to test and refine the design before full deployment. This ability to prototype at a 1:1 scale is important because it reduces errors, improves construction intelligence, and helps designers evaluate spatial quality before mass production.

Architectural Identity and Dignity

Although the project is highly rational, it does not treat efficiency as the only goal. The visual language of the housing units is soft, curved, and recognizable. The roof form gives each unit a distinct silhouette, while the printed wall texture expresses the construction method.

This architectural identity matters. Emergency housing often risks becoming anonymous, repetitive, and socially isolating. PrintDomus uses shape variation, block planning, public spaces, and service integration to create a more humane environment. The settlement is not presented as a temporary camp, but as a structured neighborhood where residents can live with dignity.

The balance between speed and dignity is the core achievement of the project. It demonstrates that affordable housing does not have to be spatially poor, and that rapid construction does not have to produce inhuman environments.

Why PrintDomus Matters

PrintDomus is relevant because it connects a technological question with a humanitarian one. The project does not use 3D printing as a visual novelty. It uses it as a construction system capable of reducing time, controlling material consumption, and improving planning reliability.

For refugee housing and emergency settlements, these qualities are critical. The faster a safe home can be built, the sooner displaced families can regain privacy, routine, and stability. The more accurately costs and materials can be calculated, the easier it becomes for governments, humanitarian agencies, and host communities to plan responsibly.

PrintDomus shows how 3D printed architecture can move from experimental discourse into real-world housing strategy. It proposes a future where construction technology serves human need directly, producing settlements that are fast, affordable, adaptable, and dignified.

PrintDomus by Elena Feruglio and Alberto Carminati presents a strong architectural response to the global refugee housing crisis. Through 3D printed architecture, the project combines rapid construction, modular planning, material efficiency, and social infrastructure into one coherent settlement model.

Its strength lies in the integration of technical optimization with human-centered planning. The use of perimeter-to-area logic reduces printing time and material demand. Shared walls improve efficiency. Strip planning supports phased construction. Public functions and green areas transform the site into a livable community.

In a world where displacement is increasing and housing systems are under pressure, PrintDomus offers a clear and timely proposition: the next building revolution should not only be faster and cheaper. It should also be more humane.
