Additive manufacturing (AM) has been getting a lot of attention over the years, with its use in construction a recurring theme. Generally this brings to mind massive 3D printers that are carted to construction sites and assemble entire homes on the spot. That’s the perspective with which a recent ZDNet article by [Rajiv Rao] opens, before asking whether AM in construction is actually solving any problems. As [Rajiv] notes, the main use of such on-site AM construction is for exclusive, expensive designs, such as ICON’s House Zero which leans into the extruded concrete printing method.
Their more reasonable Wolf Ranch residential homes in Texas also use ICON’s Vulcan II printer to print walls out of concrete, with a roof, electrical wiring, plumbing, etc. installed afterwards. Prices for these Wolf Ranch 3 to 4 bedroom houses range from about $450,000 to $600,000, and ICON has been contracted by NASA to work a way to 3D print structures on the Moon out of regolith.

Naturally, none of these prices are even remotely in the range of the first-home buyers, or the many economically disadvantaged who make up a sizable part of the population in the US and many other nations in the Americas, Africa, etc. To make AM in construction economically viable, it would seem that going more flatpack and on-site assembly is the way to go, using the age-old pre-fabrication (prefab) method of constructions.
This is the concept behind the University of Maine’s BioHome3D, which mainly uses PLA, wood fiber and similar materials to create modules that contain insulation in the form of wood fiber and cellulose. These modules are 3D printed in a factory, after which they’re carted off to the construction site for assembly, pretty much like any traditional prefab home, just with the AM step and use of PLA rather than traditional methods.
Prefab is a great way to speed up construction and already commonly used in the industry, as modules can have windows, doors, insulation, electrical wiring, plumbing, etc. all installed in the factory, with on-site work limited to just final assembly and connecting the loose bits. The main question thus seems to be whether AM in prefab provides a significant benefit, such as in less material wasted by working from (discarded) wood pulp and kin.
While in the article [Rajiv] keeps gravitating towards the need to use less concrete (because of the climate) and make homes more affordable through 3D printing, AM is not necessarily the panacea some make it out to be, due to the fact that houses are complex structures that have to do much more than provide a floor, walls and a roof. If adding a floor (or two) on top of the ground floor, additional requirements come into play, before even considering aspects like repairability which is rarely considered in the context of AM construction.

Amazon’s Leadership and Corporate Culture: Lessons from Jeff Bezos
Amazon, one of the most influential and innovative companies in the world, has a corporate culture and leadership philosophy shaped largely by its founder, Jeff Bezos. Bezos’s approach to leadership and his vision for Amazon have set the company apart in the highly competitive tech and retail sectors. This article explores the key elements of Amazon’s leadership and corporate culture, and the lessons that can be drawn from Bezos’s unconventional methods.
The Bezos Leadership Philosophy
Jeff Bezos founded Amazon in 1994, and his leadership philosophy has been instrumental in driving the company’s success. Central to Bezos’s approach is a relentless focus on the customer. He famously emphasized, “We’re not competitor obsessed, we’re customer obsessed. We start with the customer and we work backwards.” This mantra has guided Amazon’s product development, customer service, and innovation strategies.
Bezos’s customer-centric philosophy manifests in various ways. For instance, Amazon’s customer service policies are designed to maximize customer satisfaction, often going above and beyond industry standards. This includes offering easy returns, fast shipping, and a broad range of products. The commitment to customer experience is not merely a slogan but a guiding principle that influences every aspect of Amazon’s operations.
Innovation and Risk-Taking
Another hallmark of Bezos’s leadership is a strong emphasis on innovation and risk-taking. Bezos has been known for his willingness to experiment and embrace failure as part of the innovation process. His approach is encapsulated in the principle that “failure and invention are inseparable twins.” This mindset has led to the creation of groundbreaking products and services such as Amazon Web Services (AWS), Kindle, and Alexa.
Bezos encourages employees to think big and explore unconventional ideas. Amazon’s “Day 1” mentality, as described by Bezos, means treating every day as if it were the first day of the company’s existence. This approach fosters a culture of continuous improvement and creativity, where employees are motivated to push boundaries and explore new possibilities.
The Two-Pizza Rule
Bezos’s leadership style also emphasizes the importance of small, agile teams. The “Two-Pizza Rule” is a notable example of this principle. According to this rule, teams should be small enough to be fed with two pizzas. The rationale behind this is that smaller teams are more effective at communicating and collaborating, which leads to faster decision-making and more innovative solutions.
The Two-Pizza Rule has influenced Amazon’s organizational structure, promoting a decentralized and flexible approach to management. It encourages teams to be autonomous and take ownership of their projects, leading to a more dynamic and responsive organization.
Long-Term Thinking
One of the defining features of Bezos’s leadership is his long-term thinking. Bezos has consistently prioritized long-term goals over short-term gains, a strategy that has often led to criticism from investors focused on quarterly results. However, Bezos believes that focusing on the long term is essential for building a sustainable and successful business.
This long-term perspective is reflected in Amazon’s investments in infrastructure, technology, and talent. For example, Amazon’s substantial investments in its fulfillment network and cloud computing services were made with the expectation of significant long-term returns. Bezos’s willingness to forgo immediate profits in favor of future growth has been a key driver of Amazon’s success.
Leadership Principles
Amazon’s leadership principles are a cornerstone of its corporate culture and reflect Bezos’s values and vision. These principles guide decision-making, employee behavior, and company policies. Some of the most notable principles include:
Customer Obsession: Always start with the customer and work backwards. Work to earn and keep customer trust.
Invent and Simplify: Seek out new solutions and simplify processes to make things easier for customers.
Hire and Develop the Best: Raise the performance bar with every hire and promotion. Recognize exceptional talent and help them grow.
Deliver Results: Focus on the key inputs for your business and deliver them with the right quality and in a timely fashion.
These principles help create a unified company culture where employees are aligned with Amazon’s mission and values. They also serve as a framework for evaluating performance and making strategic decisions.
A Culture of High Standards
Bezos is known for his insistence on high standards, which is reflected in Amazon’s corporate culture. He believes that maintaining high standards is crucial for driving excellence and innovation. This approach has led to a demanding work environment where employees are expected to deliver exceptional results and continuously improve.
While this culture of high standards has contributed to Amazon’s success, it has also been a point of contention. Critics have pointed to the intense pressure and high expectations placed on employees, leading to concerns about work-life balance and employee well-being. Bezos and Amazon have addressed these concerns in various ways, including investing in employee benefits and programs aimed at improving workplace conditions.
Lessons for Other Organizations
Amazon’s leadership and corporate culture offer several valuable lessons for other organizations:
Customer Focus: Prioritizing the customer can drive innovation and create a competitive edge. Companies should continually seek to understand and meet customer needs.
Embrace Failure: Viewing failure as a learning opportunity rather than a setback can foster innovation and resilience. Encouraging experimentation and risk-taking can lead to breakthroughs.
Small Teams, Big Impact: Smaller, autonomous teams can be more agile and effective. Empowering teams to make decisions and take ownership can drive productivity and creativity.
Long-Term Vision: Balancing short-term pressures with a focus on long-term goals can lead to sustainable growth and success. Investing in future-oriented projects can pay off over time.
High Standards: Setting high standards and striving for excellence can drive performance and improvement. However, it is important to balance this with consideration for employee well-being.
Conclusion
Jeff Bezos’s leadership and Amazon’s corporate culture have been instrumental in shaping the company’s success and influence. Bezos’s focus on the customer, innovation, long-term thinking, and high standards has created a unique and powerful organizational environment. While there are challenges associated with this approach, the lessons from Amazon’s leadership can provide valuable insights for other organizations striving for excellence and growth.
