Why have Wasp decided to work with a Delta system and not with a Cartesian one?
Due to the Delta kinematic that works moving only the extruder, this ensures low energy consumption and less possibility to wear out the mechanical parts. Moreover, a Delta system is perfect to facilitate an easy and speedy assembly of the Big Delta, this printer is higher than 10m and Wasp have designed it to be assembled without using stairways or scaffoldings, none of this would’ve been possible with a Cartesian system.

 

What are the advantages of printing adobe houses made of terrain and straw?

•The project can be perfectly realised due to the precision of mechanical movements.

•Customisable design (architectural shapes designed by geometric modelling software).

•High efficiency and low material consumption (around half less than traditional building methods).

•Fastest, Wasp have calculated that 2 men can build a refuge in a week.

•Mixing straw and terrain, using the extruder designed by Wasp, Wasp obtain a fiber-reinforced material like a composite.

•3D printing a house is less laborious than traditional techniques.

•3D printing architectural models are improved and become even more efficient sharing knowledge.

•Increasing performances of structural elements, filling walls with selected materials (for thermal insulation or other properties.

•Cavity wall can be created, this is impossible to be obtained with traditional techniques, the aeration canals could be utilised for air-circulation, air conditioning and air heating system.

•Wasp are elaborating a building project for a house against malaria, repelling mosquitoes naturally with essential oils vaporised into aeration canals.

•Locally obtained printing material could be composed of terrain or debris of building following an earthquake or natural disasters.

•Wasp’s technology is the best solution for the emergency situations utilising recycled and minced materials.

 

It’s important to remember that a new technology opens new horizons and during researching and developing phases no-one knows what the future of 3D printing holds. Everyday we have a lot of new ideas.

 

Did Wasp already 3D print a house?
Wasp took 3 years of research to build it and now their efforts will turn to the printing house.

 

The BigDeltaWASP 12m was a fundamental step to take, the innovation that will make this dream come true. Wasp could have taken less than three years to build it, but let’s not forget that the research has been financed through the sale of Wasp’s compact 3D printers.

The printing of a house with locally sourced materials will be yet another goal achieved through self-financing.

 

What are the BigDelta 12m’s energetic requirements?
The giant BigDelta 12m printer consumes between 1 and 1.5 Kilowatt. One of the biggest issues during the design phase was that of reducing energy consumption, in order for it to be used in areas of the planet with no electrical grid, it was necessary that it could function with the energy supply of a single solar panel.

 

Which materials can be used to print the houses?
BigDelta 12m can extruder fluid-dense materials of any kind. It has been designed to be able to print materials that are found on location, a mixture of water, soil and vegetable fiber, depending on each territory.

 

Wasp’s giant 3D printer can also print cement, lime based mixtures, sawdust and polystyrene.

 

How does Wasp’s system relate with other components of the production process – such as fixtures, covers, floors and hydric-sanitary- electrical circuitry?
The BigDelta 12m can print houses that can be internally armed and refined such as any cement house. Printing the house requires a type of research touching upon several knowledge bases that are very different from each other, starting for the architectural experience. It will certainly include all the systems that a house needs, but through a more affordable and sustainable approach. Wasp also think that along with industrialised countries, we intend to bring this habitative model in the most disadvantages areas of the planet where the housing emergency is even more pressing. It will thus be necessary to plan houses with internal systems that can function anywhere, even where there is no hydric or electrical grid available.

 

Will there be high demand for this type of housing?
The demand for this type of housing already exists, Wasp are receiving requests from many parts of the world and international estimates foresee that the demand for affordable and adequate housing will grow exponentially for the over 4 billion people that live with less than $3000 a year. The majority of them will not be able to spend more than 10% of their yearly earnings toward their housing needs. To meet this demand, the UN estimate that over the next 15 years there will be an average daily requirement of 100,000 new housing units. Furthermore, along with this impelling necessity, the growing population will need to fulfil its alimentary needs even in areas of the planet that are affected by extreme climates or that are subjected to socio-economic stresses.

 

Wasp Project feels it is unimaginable to pursue this objective through an unbalanced approach that seeks to exploit the planet rather than through frugal and flexible planning, taking into consideration the entire social context. The heart and mind can rely on 3D printing technology to meet these primary human needs through a sustainable development model.

 

What do Wasp for see for this printer in the real world?
Wasp expect that it will be used for what it was designed for, to print houses. They are already receiving requests from many areas of the world that they are not yet able to meet.

 

Wasp envision states, districts and non-profit organisations that obtain a printer and decide to work side by side for the general well-being of the community. The materials and uses that will revolve around the BigDelta 12m are still waiting to be discovered, but they find it easy to believe that many enterprises that work on housing components or restoration and public ventures may develop an interest for it as well.

 

Will the BigDelta 12m be available to purchase?
Yes, the BigDelta 12m will be commercially available. Wasp build technology for humanity and for the planet and in order to do this they need to finance their research and pricing will be discussed privately.

 

Is a clay house only possible in warmer climates?
In the province of Alessandria in Northern Italy there are entire buildings that were made of clay over the past centuries and are still habitable. Ait Ben Addou, a city that is a UNESCO World Heritage site has been entirely built using raw dirt in the Moroccan inland. When Wasp went to visit it, the guide told them about the minimal maintenance requirements of clay buildings. One curiosity is newlywed couples can choose if they want to receive a green or red clay house as a wedding gift.

 

Is a clay house a real house? How sturdy is it?
Yes, absolutely. Even buildings that are several stories tall could be made of clay. They could have all the comforts of a common cement house. There are many examples, although of course none has been 3D printed. Additive manufacturing technology adds new possibilities to a material that has a long-standing tradition. These include doing almost completely away with manual work, offers much shorter times and an unexplored means of architectural expression.

 

How long will it take to 3D print a house?
The time necessary to print a house will depend on a series of factors, starting with the materials: using rapid set cement (which does not interest Wasp, although their BigDelta is able to print it) times are significantly shorter and it would take only a few hours to build walls that are several meters tall. If, instead, we choose locally sourced materials, such as clay and raw soil, it is necessary to let the material dry out before depositing more of it, in order to keep it from collapsing. For this reason, if we use natural raw materials without additives, a lot depends on the climate. In a dry and mild environment soil dries up much faster and there is no precise answer to this question. It could take a day as well as a week, much depends on the in-field variables.
