U.S. based automotive company Local Motors is changing the way cars are manufactured. Based in Phoenix, the industrial design and manufacturing outfit was one of the pioneers of cloud-based co-creation, where members of a 150,000 strong community submitted and refined ideas for products, dramatically speeding up the whole process.

The company was founded in 2007 and its first project was the Rally Fighter – a high-speed off-roader built from both original parts of off-the-shelf components.

Since the launch of this project, the company has branched out into a variety of projects, from electric bikes to home appliances and a military vehicle prototype, which was developed in under five months.

Local Motor’s CEO, Jay Rogers, is a Princeton and Harvard-educated U.S. Marine and a veteran of the Iraq War with a clear vision for how to get things done effectively and efficiently, while always leaving room for improvement. Now the company is taking that idea to the next level, one layer of extruded plastic at a time.

The latest vehicle to come out of the Local Motor’s factory is a 3D-printed electric sports car designed by a community of members from Italy. The car is currently being designed before it will be printed on location in September at the International Manufacturing Technology Show in Chicago.

Called the Strati, it’s a collaboration of Local Motors, industrial parts shaping specialist Cincinnati Incorporated and the Oak Ridge National Laboratory, where a custom printer was created for the car.

Produced from a new fiber-reinforced thermoplastic strong enough for use in an automotive application, the chassis and body without drivetrain, wheels and brakes weighs just 450 pounds and the completed car is comprised of just 40 components, a number that gets smaller with every revision.

Rogers hopes to reduce the printing time of the vehicle to just 2.4 hours by the end of 2014 and believes the entire manufacturing process can be reduced to one hour or less in the future. While the current technology extrudes about 12 pounds of plastic per hour, Rogers says the experimental limit is 1,000 times as fast. Rogers firmly believes that 3D printing could reform the industry.

While this undertaking is perfectly suited to Local Motors’ small scale manufacturing model, Rogers sees no reason that it can’t be scaled up to work on a mass production level once the speed is increased. Several of the shipping container-sized printers could pump out constantly evolving cars by the thousands.

Tapping into his military mind, Rogers envisions the printers being deployed with troops into the field to produce disposable vehicles, each finely tuned for a specific mission. It would eliminate waiting for much-needed equipment, and parts could be recycled or repurposed when the vehicles are no longer needed.

“People in the know are familiar with the massive overhead required by traditional manufacturing,” Rogers says. “The Strati is an experiment to prove this method works. If we can do it, there's no reason why we shouldn’t be doing it.”

IMF: Variants Can Still Hurt Manufacturing Recovery

The International Monetary Fund (IMF) claims that while markets are rising and manufacturing is coming back, it’ll push for global immunisation

After a year of on-and-off manufacturing in the US, UK, and the eurozone, demand for goods surged early last week. Factories set growth records in April and May, suppliers started to recover, and US crude hit its highest price point since pre-COVID. As vaccination efforts immunise much of the US and UK populations, manufacturers are now able to fully ramp up their supply chains. In fact, GDP growth could approach double-digits by 2022

Now, the ISM productivity measure has surpassed the 50-point mark that separates industry expansion from contraction. Since U.S. president Biden passed his US$1.9tn stimulus package and the UK purchasing managers index (PMI) increased to 65.6, both sides of the Atlantic are facing a much-welcomed manufacturing recovery. 

Lingering Concerns Over COVID

Even as Spain, France, Italy, and Germany race to catch up, and mining companies pushed the FTSE 100 index of list shares to a monthly high of 7,129, some say that UK and US markets still suffer from a lack of confidence in raw material supplies. Yes, the Dow Jones has made up its 19,173-point crash of March 2020, and MSCI’s global stock index is at an all-time high. 

Yet manufacturers around the world realise that these wins will be short-lived until pandemic supply chain bottlenecks are solved. If we keep the status quo, consumers will pay the price. In April, inflation in Germany reached 2.4%, and across the EU’s 19 member countries, overall prices have increased at an unusual pace. Some ask: Is this true recovery? 

IMF: Current Boom Could Falter

Even as Elon Musk tweeted about chip shortages forcing Tesla to raise its prices, UK mining demand skyrocketed; housing markets lifted; and the pound sterling gained value. The International Monetary Fund (IMF), however, cautioned that manufacturing recovery won’t last long if COVID mutates into forms our vaccinations can’t touch. Kristalina Georgieva, Washington’s IMF director, noted that fewer than 1% of African citizens have been vaccinated: “Worldwide access to vaccines offers the best hope for stopping the coronavirus pandemic, saving lives, and securing a broad-based economic recovery”. 

Across the globe, manufacturing companies are keeping a watchful eye on new developments in the spread of COVID. Though US FDA officials don’t think we’ll have to “start at square one” with new vaccines, the March 2021 World Economic Outlook states that “high uncertainty” surrounds the projected 6% global growth. Continued manufacturing success will in large part depend on “the path of the pandemic, the effectiveness of policy support, and the evolution of financial conditions”. 

Mathias Cormann, secretary-general of the Organisation for Economic Co-Operation and Development (OECD) concurred—without global immunisation, the estimated economic boom expected by 2025 could go kaput. “We need to...pursue an all-out effort to reach the entire world population”, Australia’s finance minister added. US$50bn to end COVID across the world, they imply, is a small investment to restart our economies.
