Québec’s Economic Strategy for 2017-2022

Premier of Quebec, Philippe Couillard:

“Our goal is ambitious, but achievable, and by 2022, we want to position Quebec as one of the top 10 leaders of the Organization for Economic Co-operation and Development (OECD) in terms of research and innovation. We intend to become one of the most innovative regions in the world, recognized as fertile ground for talent, ideas and solutions to the great challenges of our time. ”

2017-2022 Strategy:

“In total, the government will spend $ 5.4 billion on research and innovation over the next five years.”

“Inspirational projects” … These three objectives are implemented through support for “inspirational projects”, new research and innovation projects focusing on specific missions, particularly representative of the potential of promising niches or having the ability to address societal challenges. ”

Whaddya say?

Self Management

(This is a guide. All links are to good quality information, in most cases to studies.)

Self-management is co-created organizational model that progresses from collective, hierarchical, or militaristic organizations. It is supported by more than a century of rigorous field and theoretical research in multiple fields. Please follow these links to learn more about organisational empowerment in:

It produces profit and benefits for small  and large enterprises, and is being simultaneously developed in organizations around the world . Regional economies around the world depend on such organizations and skills, from family rice farms in China to much of the economy of Prince Edward Island since the 1970s. in Quebec, the Ministry of the Economy, Science and Innovation (MESI) and many other stakeholders are mobilizing to train and support Quebeckers in these practices.

Some synonyms include: self-management, horizontal management, sociocracy, participatory democracy, agile management.

How it works

Each of us is empowered to take any decision to meet a challenge or opportunity for the organization, with a duty to consult.

The duty to consult rests with the decision taker, and they must consult not only with appropriate experts within and outside of the co-operative, but also with any people who may be affected by the decision.

We prioritize our actions as per their effect on the planet, people, and profit. In that order, because without the first we don’t have the next.

In case of conflict, the concerned people have 3 levels of recourse:

  • Taking the time needed to talk it out together
  • Asking a colleague to hear and mediate
  • Ask a council of colleagues to decide

It depends on these assumptions

We trust each other.

People working with us want the organization to succeed in its efforts.

Radical transparency allows people to bring their whole selves to work and in particular fosters the critical feedbacks that feed innovation

We can reduce work hours, be flexible to the myriad and changing needs of our colleagues

Sharing resources enriches everyone

Such organizations require modified resource allocations

  • Salaries and purchasing are set by the person or people concerned
  • Much larger training budget:
  • Some people can’t adjust to taking responsibility, but generally people can and do
  • Significantly modified intake process for new colleagues, takes up to 18 months
  • Upstream and Downstream ecological or social considerations take precedence over internal profit considerations.
  • More complex to finance – is built around partnerships, particularly instead of traditional supplier/client relationships.

They outperform the competition

These models are out-producing their traditionally-run competitors on standard metrics like profit and growth as well as on resilience in the face of change, corporate longevity, client loyalty, and employee retention.

House-Printing Machines

A brief glossary of technical terms as well as links to good information are provided at the bottom of the page.

The machines and processes that will change everything tomorrow are more than ever being built in your own community. Makerspaces, repair cafes, fablabs, transition clubs, democratic schools and permaculture workshops are just a few of the spaces where it’s happening, and mostly people are using freely available tools, knowledge, and equipment.

Machines Available for Sale

These are extrusion-based 3d printers that can be used in large-scale automated construction, available for sale or being used to make buildings for sale to a global market. There’s something here for many different projects, climates, and budgets. Some of them are open-source, almost all of them use simple publicly available knowledge and equipment, and some use proprietary materials.

California, Erectorbot: Open-source 3d printer with a large, fast, adaptable extruder which prints filament or converts pellets of various materials on the fly on a giant scalable print area up to 20 x 30 x 10 feet. A standard cartesian model.

Russia, Apis-cor: Using a very sturdy looking polar printer that extrudes from a pivoting central arm, this Russian-American collaboration has a radius of 6.5 meters on the ground and the company have printed this fabulous 132 m2 round yellow house in 1 day, which is among the fastest print time claims in the world. They are offering machine kits for sale, and then they provide a recipe or additives to local concrete producers to allow for quick-drying concrete prints.

South-Carolina, Branch Tech: An architectural firm, they have a scara model on rails that makes particular use of newly identified complex geometries to build skeletal wall structures. Not for sale. They did a design contest 2 years ago to get a house built with their machine, but no other news on a finished building. A really beautiful set of designs is showcased on their site.

Amsterdam, 3D Print Canal House: A group of architects have built a large cartesian model and are working on making solid bio-plastic structural elements for assembly and tests on site. They are also testing other eco-materials for printing. Speed seems a main challenge, and they added a second machine to their projects last year. They invite collaborations.

China, Winsun and other companies: The first to 3d print houses, the controversial Winsun company does not sell nor make public their processes and concrete recipes. They do however sell the mixture, and concrete structures to municipalities in the middle-east. Chinese competitors to Winsun have also emerged, particularly in Shanghai and the northern provinces, working on a variety of processes.

Other groups have made announcements, but are not ready to go to market at this time. Some are controversial.

In Development

Should you be on this list? Let us know!

Multinationals: Stratasys, Makerbot, 3D Systems : These are the larger companies in 3d printing that will likely have an interest in this scale. Expect to see them working with the companies that suit their needs and interests in order to take market share on machine sales.

Montreal, Print Our Home  : A nonprofit group in Montreal, Canada, looking to make sustainable, healthy 3d printed homes available to everyone. Focusing on processes using local and standard eco-materials.

Italy, DeltaWasp: An Italian giant delta model, this machine uses clay on site to build. They appear to be in the final stages of research, and from their mission would seem likely to be open-source.

USA: Contour Crafting: A company in California working with NASA to create a healthy and strong concrete and concrete additives for FDM construction and space applications.

Saskatchewan? … if you’re working on this stuff in Canada, we’ve heard of you but can’t find you online.

Get in touch, if you’d care to work together.

Glossary and Links

Printing technologies at Some related terms:

Extrusion / Fused Deposition Modelling: Thin layers of material are heated and laid out on a surface, then additional layers are added on top of the first to fuse and strengthen together into a detailed sculpture. We can extrude hundreds of materials, from concrete, wood, and metal, to plastic, food, and clothing. Even living cells.

Complex geometries: Researchers are using 3d printing’s capacity to deliver complex shapes for little or no added effort to create super-strong 3d geometries.

Printer types as per, and some related terms:

  • Cartesian: Typically a cube shape, uses x, y, z coordinates and a movable bed
  • Delta: Cylinder with a fast extruder in the center.
  • Polar: Uses polar coordinates, and a circular, spinning bed.
  • Scara: A multi-jointed robot arm with a very small footprint, often runs on rails.

Materials, according to, and some related terms:

  • Filament: Extrusion material in long thin threads on spools, to be fed into extruders, which process and deposit them on the print surface.
  • Pellets: Extrusion material provided in pellets, such as metal alloys or plastic composites.
  • Additives: In concrete, meant to increase drying times without compromising strength. May be publicly known or a trade secret.

A note on the media and 3d printing:

Everything is changing very quickly, including a huge reduction in newsroom budgets and a big increase in promotional spending by many small, medium, and mega-large organizations. Take everything with the critical eye it merits, and look to your local maker and repair communities for inspiration on tomorrow’s products.

Automation and Residential Construction in Quebec

by T Mackenzie

Can we build a machine to print houses?

We can. Drawing on existing technologies and materials, we can build a mobile machine that recycles construction waste to print custom houses. The Print our Home team have detailed plans for doing so. However, being able to automate construction raises a second question:

Should we?

On production cost savings alone, automation is widely held to be inevitable in the current market structure (McKinsey Global Institute).  Yet a process that stands to affect 5% (CCQ) of the Quebec workforce and that aims to significantly reduce building costs is a machine that will have a profound social effect.


The construction workers and engineers of Quebec are global leaders. In order to remain so, we must adapt. Expertise and experience with large-scale automation and green building technologies are a viable focus for our workforce, our industries, and our training centers.

In addition, construction automation benefits individual workers by reducing the cost of a home by tens of thousands of dollars – up to 35% off a new home with certain techniques. At average prices and mortgage rates in the suburbs of Montreal, this can represent $ 150,000 or more per family over 25 years.


Above all we consult with and respect the needs of the people who may be affected, such as: investors, family and friends, local communities, Kahnienkehaka, Anishanaabe, other First Nations communities, and all others, in a spirit of equity.

We have found that automation and processes related to “Industry 4.0” has other social benefits.  They relieve labor shortages, improve the health and safety of job sites, and allow small businesses the economies of scale previously only available to large companies.

We consider the possible effects of our decisions on people and on the planet. We integrate our projects into the local community, to the mutual and long-term benefit of everyone in our region. (To do so, Print our Home have undertaken a long-term data-based and philosophical study of the effects of our technologies and activities: Discussion: Automation and Quality of Life in Quebec). 

The Environment

The demands of planetary stewardship require innovation, too. Thankfully, there is a growing body of research and real world examples of the tools needed to transition to a sustainable economy.

How do we do it right?

What new tools? Do they still satisfy financial bottom lines? Solutions are emerging, things such as full cost accounting (HRH Global Accounting Initiative, Bookkeepers Can Save the World), reduced work weeks (Forbes), basic Income pilot projects in multiple countries (Toronto Star), self-management, and robust open information and maker movements that are rocket-fuelling innovation.(Open Source Hardware Association, Baylor University)

The choices involved in technology are, in the end, the same as in other human endeavors: Can automated construction be done? Yes. Can it serve our needs? Yes. It comes, and we get to drive.
