2 - Additive Manufacturing Thematic Dossier

It’s always an invigorating challenge to write editorial on a subject which is at the forefront of innovation. It is an immense pleasure and at the same time

a difficulty, such are the numerous interrelated implications and impacts.

The subject of this thematic file relates to Additive Manufacturing, or 3D printing, applied to property construction and civil engineering. It concerns digital transformation and BIM, collaborative robots and disruptive technology on a market which is reputedly ‘conservative’.

The Magnitude of the Trend As far as automation and robotics are concerned, every year the previous year's record is shattered, and 2016 was no exception to this rule: sales of industrial robots exceeded 250,000 units in 2015, not to mention Foxconn and others, like Amazon, who are developing their own robots, with Foxconn alone having 60,000 of them in its facilities.

Additive ManufacturingAcceleration in the Maturity of Technology and the Ecosystem

Additive manufacturing is not a new process, but its rapid spread into all domains has been accelerated by the tidal wave of digital transformation. BIM, the digital modelling of buildings, paves the way for a new way of constructing a home, which involves customised creative design, new materials, and reduced timescales and economic impact.In collaboration with the In Extenso Innovation Croissance Consultants, we are able to provide you with an up-to-date global view of the ins and outs of this technology applied to the Construction industry.

THE MARKET

Unstoppable growth in the importance of the digital value of buildings

Technological progress in terms of sensors, coupled with new storage and analysis capabilities, are encouraging a significant increase in digital and digitised information in the Construction industry.

In fact, data is becoming a key element to the creation of new wealth and new professions throughout the life cycle of a building. For a new-build or a renovation, from its construction through to the operational phase, the challenge today is to develop a digital data continuum between the design, the construction, the property and the urban environment.

This growth in the importance of the digital value of buildings and infrastructures is reinforced by technological software innovations, and also by the following which are non-software related:

- New 3D technologies (immersive rooms, augmented or virtual reality via head-up display devices) reinforce the visualisation advantage of BIM. On this matter, our analysis tends to conclude that industry players first of all need to develop their BIM maturity before being able to fully harness synergies with these technologies.

- Technological advancements in respect of data exchange due to cloud storage services.

- The advancement of digital capture tools such as 360° cameras or 3D scanners.

- Economic benefits of manufacturing and prefabrication due to the integration of 3D printing technology.

- The addition of automatic data collection by all sensor types, i.e. connected objects (the embedding of an RFID chip inside a concrete wall) (SHM: Structural Monitoring).

As the manifesto ‘Driving digital transformation for Construction, Housing and Urban Development’ highlights:

“A double challenge is posed to the Construction Industry: integrating digital technology into its processes to increase productivity within the sector, but more importantly, knowing how to suggest appropriate usage of these tools outside of the design and construction phases, in competition with other players who still do not have experience of the building or development processes.” In fact, digital transformation of the sector is generating more and more digital avatars of buildings, districts and territories.

This ‘digital territorial asset’ represents a territory's lever of attractiveness and competitiveness, in the same way as transport infrastructures, public facilities and even urban developments do.

OVERVIEW OF THE 3D PRINTING MARKET IN CONSTRUCTION AND CIVIL ENGINEERING The Revolution of the Construction and Civil Engineering Industry

By David Afriat


Additive Manufacturing: A Market in Steep Growth, Due to Reach Almost $20 billion by 2020Spurred on by growing user maturity and an increasing number of uses, the Additive Manufacturing market is experiencing rapid growth which has accelerated throughout recent years.

In fact, sales of machines, consumables and related services have experienced an annual average growth of almost 27% in recent years. As a true indicator of this acceleration, this same variable reached a rate of 33.8% in the period 2012-2014 and demonstrates the buzz around manufacturers and organisations for this expanding market which has become more accessible due to the expiry of certain major patents.

At the end of 2014, the global Additive Manufacturing market was valued at over 4 billion dollars by the firms Wohlers Associates and AT Kearney, an amount which does not take into account the investments made by manufacturers which have possibly been hidden or are currently in progress.

Growth predictions for Additive Manufacturing by 2020 vary greatly depending on the source, and fluctuate between 11.7 and 21.2 billion dollars. In parallel, research firm Canalys and American company International Data Corporation envisage an even more marked acceleration, with the market having an estimated value of 16 and 21 billion dollars respectively from 2018.

These figures are undoubtedly optimistic and probably include secondary impacts such as moulds, templates and various tooling or parts produced by this equipment.

THE MARKET

Progressive Penetration of 3D Printing into the Construction Field Renowned for being very conservative, Construction and Architecture puts itself in a secondary position with 3.2% of the global Additive Manufacturing market, with interesting potential. Today, the initia-tives of pioneering players almost exclusively involve the use of concrete and aim to reduce the timescales for completion of a construction or housing project. Studies may be carried out on those involved in the Aggregates sector in order for resin/sand mixtures to be proposed, but this remains relatively distant from these applications.

The needs expressed in Construction and Civil En-gineering are many: repairs, the manufacture of a complex component in short runs for a piece of civil engineering, the swift construction of urgently-re-quired homes, low-cost replication, creative archi-tectural forms, etc. 3D construction now enables the building of houses directly on site within very fast timescales, with the ability to be free of geomet-rical constraints and to propose innovative architec-tural forms.

The rise in 3D printing in the Construction and Civil En-gineering industry has only just begun, yet it presents a potential to disrupt current tools and construction methods, as well as site completion timescales. Nevertheless, the regulatory barriers to be lifted in order for the use of these technologies to be ap-proved are very robust.

It is important to specify here that the below stud-ies carried out on the maturity and dissemination of the technology within the Construction and Civil Engineering industry arise from conclusions on the prospective study on the future of Additive Man-ufacturing conducted in 2016 (on behalf of the Di-rectorate General for Enterprise). Indeed, in light of the rapid obsolescence of machines and technologi-cal advances, it is likely we will see the market evolve more rapidly with the appearance of processes which are already offering solutions ahead of the envisaged time frame.

On the one hand there is indeed a large effort to be made in order for a formulation to be developed that is suited to conditions whereby it can be im-plemented by layer: with every new layer, one must ensure the lower layer does not collapse due to faster concrete setting times (setting accelerators and ad-mixtures). Furthermore, there is poor understanding of how concrete changes according to climatic con-ditions or how site location limits usage to the man-ufacture of components prefabricated in warehouses where the atmosphere is controlled.

If the sector adopts a forward-thinking approach, pri-mary specific uses envisaged involve the use of Addi-tive Manufacturing to quickly create resin moulds at low cost, so that a complex element can be poured into concrete (with the mould generally being de-stroyed), or even for this process to be used for the manufacture of casing which will then be used as in-sulation. In the short-term, this development resem-bles a fast tooling project and enables one to quickly benefit from the advantages of the technology.

In the medium term, the acceleration of the process and the development of new formulations should allow for the industrialisation of the direct manufac-ture of sub-assemblies by additive manufacturing, in a known, controlled atmosphere. Finally, a better understanding of the behaviour of concrete may facilitate the prediction of adjustments which need to be made according to conditions and the place where the concrete is to be poured, and make it possible for individual houses to be built in situ. In the short term, this increasingly accessible primary market offers an interesting opportunity for users of pumped concrete to construct a property, or an element of it, directly on site.

Another aspect of regulation is certifications…This will clearly be a competitive advantage for those who are able to accommodate new processes, an im-provement in materials and maintenance processes and the anticipated national/regional certification, and perhaps even exceed expectations.


Overview of the Socio-Economic Impacts of 3D Printing in Construction and Civil Engineering, and the Parties InvolvedIn the near future, concrete 3D printing tech-nology should provide builders with an inno-vative solution for how to work faster at lower cost and be able to respond to many societal challenges. In fact, one of the main advantages lies in the speed of implementation and com-pletion of a project, which allows for the strain and manufacturing timescales of housing programmes to be reduced.

Moreover, this record printing time consider-ably impacts construction costs, in that this process needs far less in the way of human resources and materials than conventional construction methods. According to Contour Crafting (University of Southern California), the additive manufacturing process could allow for a 75% reduction in CO2 emissions and a 50% reduction in grey energy (total energy consumption measured in kWh/ton, for the production of a material throughout its life cycle, from its extraction, to its transformation, to its recycling) in comparison with traditional techniques.

In fact, Additive Manufacturing offers the pos-sibility of only using materials that are strictly necessary for the execution of the project, thus limiting waste, transport costs and even the cost of raw materials. With concrete and ce-ment production being one of the highest car-bon dioxide producing activities in the world, it is easy to understand the long-term impact of 3D printing in construction.

Finally, the integration of functions and the ability to produce complex parts, shapes and volumes at virtually no extra cost release creativity from the constraints of traditional construction. This architec-tural revolution presents new opportunities in terms of usage and design in order to broaden the aesthetic value and comfort of buildings at affordable prices.

THE MARKET


THE MARKET

Market Forces:Since the 1990s, the Construction industry has seen a certain number of players emerge within the field of 3D concrete printing, the precursors often being from research laboratories with the profile of Con-tour Crafting from the University of Southern Cali-fornia or BatiPrint3D from the University of Nantes. It is an ecosystem in which Europe and France are

well positioned, with players such as Construction 3D, Xtree, WASP, BatiPrint3D and even Cybe Construction who regularly communicate and surround themselves with highly-regarded partners.

France: • Construction 3D: Printing machine based on a hydraulic lifting crane• X Tree: Partnership with ABBB, 3DS and Lafarge along with various Civil Engineering contract providers• BatiPrint 3D: The creation of a 95m2 bungalow in 3 days

Italy: • WASP: Big Delta 3D printer using local resources to produce low-cost clay buildings

The Netherlands: • DUS Architects: Bioplastic wall sections printed by a robot, then assembled like Lego bricks• Slaapfabriek Hotel/Bouwend en Innovatief Nederland: Printing of the first European hotel complex• Cybe Construction: Demonstration carried out by Bouygues Construction during the VivaTech trade fair (2.5m curved wall in 30 mins)

USA:• MIT: Autonomous 3D printing (concrete or foam insulation)• Total Kustom: Printing inspired by the RepRap of a 3m by 5m castle.• Contour Crafting: University of Southern California spin-off, in situ 3D printing

house directly on site in 40 days


When Additive Manufacturing is used for Tooling and New MaterialsAside from the printing of buildings (factory prefab-ricated or not) and infrastructures such as the bridge constructed in 3D by MX3D in The Netherlands, Ad-ditive Manufacturing may also, on occasions, impact other links in the value chain by revolutionising usage:

- Parts and tooling: Likewise with other industries such as the Automotive and Aeronautical sectors, the creation of templates, fittings and other oper-ational assistance tools throughout the production process also represents an industry reality (which is, at times, more immediate than direct manufac-turing). For example, to model and produce a key through 3D printing, connecting up, rather than ma-chining it or having the operation carried out in an external workshop, allows for a considerable reduc-tion in cost, availability issues and delay in the sup-ply of bespoke manufactured parts. For slightly more mature stakeholders, the design freedom offered by Additive Manufacturing should allow for an increase in the performance of different tooling: the weight,

balance and positioning have a direct impact on the Engineer’s comfort and the throughput of produc-tion and assembly operations.

- New materials: Like with the ‘Cool Brick’, 3D print-ing spurs innovation as much in terms of design as in the construction materials themselves. Indeed, American designers have devised a building brick with natural air conditioning properties. The lat-tice element multiplies the heat exchange surfaces, maximising the porous capacity of the ceramic ele-ment. Each brick therefore absorbs water contained in the air which then lowers the temperature as it evaporates.

- The evolution of standards: The manufacturing possibilities offered by the new process, along with the materials used, should allow for the technical performance, aesthetics and energy consumption produced to be pushed by certification bodies (for example, the Centre for Scientific and Technical Construction (CSTB) with heat regulation RT2012...).

THE MARKET

Caterpillar Invests in a Specialist Robot-Builder Start-up Caterpillar has just invested 2 million dollars in Fastbrick Robotics, the Australian company from which the Robot Builder known as Hadrian X originates, capable of laying 1000 bricks per hour. The two companies will work together on the development, manufacture, sale and service of this bricklaying technology, with a newly established Strategic Alliance Council which identifies the best ways of introducing Hadrian to construction customers in different countries. Erected on a 30m-long boon attached to a truck, Hadrian X is a robot-builder which can be quickly positioned and is capable of remaining in one position throughout its work. A 3D CAD model of the house is entered into the system and, by following these instructions, the robot is able to cut and position up to 1,000 bricks per hour, taking into

consideration doors, windows, features and channels for electric cabling and plumbing.


THE BATIPRINT3DTM PROCESS

BatiPrint3DTM is a Leading Technology for an Innovative Robotised ProcessPatented by the University of Nantes, BatiPrint3DTM is the result of the combined work of two Nantes laboratories: LS2N (specialised in the development of the robotic system), and GeM (involved in the study of materials, formulation and characterisation).

Their aim: to build affordably-priced housing which adapts to the terrain, is customisable, quick to deliver and has low running costs.

This cutting-edge technology entails the depositing of 3 layers of material via an industrial poly-articulated robot: two layers of expandable foam serve as casing to a third layer of concrete. Once the erection of the walls is complete, the foam remains in place to ensure insulation of the room without a thermal bridge. The robot’s trajectories are guided by a laser sensor, from the digital model of the house, directly onto the concrete slab.

Fixed onto an AGV (Automatic Guided Vehicle), it adjusts to the external environmental constraints of the construction site, and is stable so that it can achieve controlled injection of the material. At the end of the operation, the mobile robot comes out through an access point where the woodwork is scheduled to be implemented. It can then be transported to another site to complete further constructions.

Economic and Environmental Advantages This process will make it possible for construction time to be reduced, for heat insulation to be improved, and for the operational costs of construction to be reduced. The use of a mobile robotised method will enable a redefinition of ways of working in the Construction and Civil Engineering sector, which are needed, as they are in manufacturing, in order to reduce the arduous nature of the work and to limit high-risk positions or causes of MSD (Musculoskeletal Disorders).

According to Benoît Furet, Professor at the Nantes University Institute of Technology, Researcher at the Nantes Digital Science Laboratory (LS2N) and Leader of the BatiPrint3DTM project: ‘It is evident that site robotics are going to accompany drastic changes in relation to the digitisation of Construction and Civil Engineering. BatiPrint3DTM is a constructive concept for which numerous applications are going to be found and for which we are going to broaden usage possibilities.”

It is an Approved Process and if Conforms to the Most Stringent Regulations Supported by the scientific expertise of the CSTB, and the technical analyses of SOCOTEC and design office EGIS, which have provided essential added value, the team from the University of Nantes has been able to offer solutions relating to the categorisation and durability of materials, the co-ordination of professions, and energetic and acoustic comfort.

This creative and technical work carried out in tandem with the architect TICA also led SMA’s design office to secure the site for Nantes Métropole Habitat.

Throughout the project, every professional has brought their expertise in order to develop new solutions and innovate practices, to succeed in going from a 3D printing robot to the construction of a durable, habitable, certified house.



YHNOVA: THE FIRST SOCIAL HOUSING PRINTED IN 3D

YHNOVATM,The First Social Housing Printed in 3D

During Nantes Digital Week in September 2017, you will be able to discover YHNOVATM House, the first social housing built in just a few days using a 3D printer. This project has been enrolled onto the Nantes City Lab process and is the result of close collaboration between the University of Nantes, Nantes Métropole Habitat organisation, Nantes City and SATT Ouest Valorisation and their partners.

Nantes City Lab, Laboratory for Life-Sized Experiments

Nantes City Lab is a scheme which is both simple and ambitious, aimed at start-ups, SMEs, large groups, public-sector stakeholders, researchers, schools, associations etc… its aim is to construct the city of the future. In this way, the territory of the City of Nantes asserts itself as a testing ground for all those who wish to develop and test innovative solutions.

It is within this framework that the different partners of this unprecedented innovative project united their knowledge and expertise to facilitate the construction of an experimental social housing property in Nantes, directly on-site in a Nantes neighbourhood.

YHNOVATM House

With a surface area of 95m2, YHNOVATM House is located in the Bottière district of Nantes and comprises five rooms, rounded walls, corners, and door and window apertures... a set of complex architectural forms that will be created through a revolutionary Additive Manufacturing robotised technology: BatiPrint3D™ patented by the University of Nantes.

Architectural firm TICA, who carried out the project, took advantage of the new robot printing process to design a house which slides into tree-covered terrain, respecting the existing vegetation whilst providing a sleek surface in consideration of the environment. Charles Coiffier shared with us that: “Amongst other things, the innovative process allows us immense project ‘contextualisation’. For this house in par-ticular, we have been able to complete a very re-spectful project with regards to existing vegeta-tion. The rooms of the property effectively slide between the trees at a sufficient distance so as to preserve the root network, and are connected by long outstretched curved walls between them, marking out a large open central living space in the wooded area. ”


Interdisciplinary TeamworkThe YHNOVATM project is an opportunity to face and resolve all the technical, acoustic, thermal, regulatory, environmental and urban constraints etc., with the support of different experts involved in the construction.

As the result of interdisciplinary work between the research teams of the Nantes Digital Science Laboratory (University of Nantes, the National Centre for Scientific Research (CNRS), Ecole Centrale, the Institute for Research in Computer Science and Automation (INRIA) and IMT Atlantique) and the Civil and Mechanical Engineering Research Institute (University of Nantes, CNRS, Ecole Centrale), this innovative system of depositing a triple encased/insulating/structural wall, means the walls of a house can now be constructed using 3D printing directly on-site in just a few days.

The YHNOVATM development is supported by the Caisse des Dépôts et Consignation (CDC) (bank which

YHNOVA: THE FIRST SOCIAL HOUSING PRINTED IN 3D

deals with deposits and loan funds), within the context of its support for projects related to Smart cities and the national roll-out of ‘demo Smart Cities’ intended to accompany experimental projects.

The Role of Ouest Valorisation

The Technology Transfer Acceleration Company Ouest Valorisation, sole representative of research establishments in Brittany and Pays de la Loire, is fully playing its role here as technology investor by consolidating the protection of research results and by building an ambitious valuation strategy for the BatiPrint3DTM manufacturing process. Vincent Lamande, Chairman of SATT Ouest Valorisation states: “We are very happy to contribute towards strengthening the competitiveness of regional players and to accelerate the transfer of innovation, thanks to the investment we have committed and thanks to academic research of an international calibre.”

POST-YHNOVATM: ROADMAP

THE ROADMAPpost-YHNOVATM


BatiPrint3DTM: TRL7 Index Achieved! Ready for TransferAs a system of measurement used to assess the maturity level of a piece of technology (materials, components, peripherals, etc.), the TRL level (Technology Readiness Level) enables the maturity of a process to be positioned in respect of the integration of this technology into an operational system or sub-system.

By being applied to the in situ construction of a full-scale house, the BatiPrint3DTM process is confirmed as having reached level TRL7: System prototype demonstration in an operational environment.The construction of YHNOVATM signifies a major landmark in innovation through the approval and formalisation of the technology and the elimination of risk. On the strength of this accreditation, technological transfer to the economic world is now the next stage.

The flagship project of the YHNOVATM demo has strengthened the collaborations between the University of Nantes and members of the Construction industry (builders, social housing landlords, architects...), with the assistance of SATT Ouest Valorisation, a technology investor in the maturity programme.

The Roadmap: Industrialisation, Start-Up, YHNOVA2… The creation of a start-up based on the BatiPrint3DTM construction principle is a favourable development method. It should take shape very shortly, and in light of this a piece of work is underway on the industrialisation of robotised methods and machinery associated with the construction principle in order for the process to be replicated on other builds and to ensure there is benefit from feedback on the YHNOVATM project.

The LS2N and GeM teams are also thinking about new experiments which would enable them to meet market expectations with the creation of other types of housing, such as the construction of houses with another level, obviously a first floor upper level.

Spurred on by the enthusiasm of the collaborative working achieved by the consortium, and with a certain amount of pride in contemplation of YHNOVATM, a YHNOVA2 is already being considered by Nantes Métropole Habitat and Nantes City.

Exploration In addition to the development of the revolutionary BatiPrint3DTM process, new themes and research topics are being drawn onto the roadmap: research projects on Additive Manufacturing, Robotics and even new construction principles and new materials.

With the strength of society’s expectations on this matter, there is the possibility of working with organically-sourced materials (a project is being put together with Norwegian colleagues from SINTEF, another with French suppliers of raw earth, etc.) and the development of robotic site solutions (with partners like PRB, Manitou, Bouygues, etc.).

Always conscious of the need to conform to regulations and certification inherent to the Construction industry, the development of the BatiPrint3DTM process has enabled us to gain a glimpse of performance developments (CSTB, RT2012 certification, etc.), as much through new construction processes as through the materials used. BatiPrint3DTM could ‘move the goalposts’ of energy performance of the sustainable building.

The future of BatiPrint3DTM therefore translates into different forms of development, in terms of new topics for research, for the creation of value, for industrialisation, for the creation of commercial activities, etc.

POST-BATIPRINTTM: ROADMAP


THE ECONOMIC IMPACT OF BATIPRINT3DTM


on the Construction Process

As innovative, pertinent and disruptive as a new technology may feel, it cannot escape the pressing need to meet the market with an

adapted business model and proven economic or usage benefits.

In the field of Additive Manufacturing applied to construction, the impact of technology affects several aspects of the ecosystem and the value chain.

Being a hybrid solution, BatiPrint3DTM combines:

- several operations that would previously have been carried out individually (3 layers) into a single construction process,

- materials and their new formulations adapted to the new method of operating,

- and characterisation, in respect of CSTB certification performance level.

For those who are experienced in 3D printing at different levels of the construction processes, economic figures have been issued concerning either the cost of manufacture per m2 or the economic income per construction post.

For the first small-scale house built in situ, APIS reported construction costs of $10,134 for a 38m2 house, being approximately $275 per habitable m2.

(Source: http://apis-cor.com/en/)

The figure announced is strongly questioned by professionals within the industry as it is so far from present day construction ratios.

With the final cost per dwelling being an essential criterion in the choice of construction, with BatiPrint3DTM we wanted to assess the economic impacts on three different types of construction for the purposes of carrying out representative benchmarking of typologies of the French market, specifically 3 types of housing:

- an ‘individual’ home, typically a 100m2 house,

- a home ‘in a strip’ consisting of a programme of individual semi-detached 1000m2 duplex homes split into 12 dwellings.

- a home ‘with an upper floor’ consisting of a programme of 5000m2 homes split into 75 dwellings.

The BatiPrint3DTM process brings an economic benefit to a certain number of plots or construction posts:

- a direct impact on the first fix, the comparison is made in relation to the construction process in individual blocks built,

- an indirect impact on the second fix: outer insulation and inner lining,

- a direct impact on project management/monitoring through provision of the BIM and digital continuity of modelling: automatic calculations of robot trajectories, procurement and integrated logistics with ERP systems, and ‘post-site’ follow-up by way of the provision of digital data about the building,

The initial cost reduction estimates by project type, provided at the cost price of the complete dwelling, are going to make savings spring from 6% to more than 10% depending on the type of construction. This figure is the result of a weighting of the impact of BatiPrint3DTM on each construction post concerned. The first fix function is quite clearly the most impacted, followed by that of second fix of inner and outer insulation.

The indirect contributions related to the field of ‘CSR’ have not been quantified at present, but significant impacts are: a reduction in the cost of CO2 in relation to logistics and a reduction in site waste.

As referred to by In Extenso Innovation Croissance, quoting Contour Crafting, “The additive manufacturing process could allow for a 75% reduction in CO2 emissions and a 50% reduction in grey energy (total energy consumption measured in

kWh/ton, for the production of a material throughout its life cycle, from its extraction, to its transformation, to its recycling) in comparison with traditional techniques.”

On a more sensitive subject, the societal contribution and its impact on employment (retraining, the reduction in physical strain and accidents, etc.) have not been covered.

YHNOVATM House is taking shape at the time of publication of this file. The economic study will be updated and consolidated following feedback on the accomplishment and performance of the process.
