Top 15 3D printing stocks from around the world
3D printing is revolutionising the way manufacturing works. We look at the market and outline the top 15 3D printing shares to consider.
What is 3D printing and how does it work?
3D printing creates three-dimensional objects that are designed on a computer. The computer commands the printer to lay down thin layers of material, such as plastic or metal, to build a physical object with precision.
The technology belongs to the world of ‘additive manufacturing’, whereby an object is made by combining many bits of material. Additive manufacturing is one of three ways to make a product. The others are ‘subtractive manufacturing’, whereby an oversized block of material is chipped away and shaped to make something, and ‘moulding’, when the right amount of material is shaped or moulded into a product.
3D printing market: from past to present
3D printing is not a new technology. The first patent related to 3D printing was issued to Charles ‘Chuck’ Hull in 1986. The patented nature of the industry meant development was held back for decades but, since crucial patents expired in 2009 to pave the way for the first home 3D printer to be released (named the RepRap3), the industry has opened up and advanced.
But it was a slow start for the industry. Even though the market had been more accessible for seven to eight years, annual 3D printing revenues for publicly-listed companies grew by just 5% per year in 2015 and 2016 - hardly a figure to get excited about. Even today it is often omitted from the list of technologies that are set to drive the fourth industrial revolution, unlike 5G, artificial intelligence or big data.
But, having evolved, it seems 3D printing is coming into its element. Growth is accelerating and the technology is starting to become an invaluable tool for manufacturers. A slew of new entrants have joined the market and new uses for the technology are still being discovered. Plus, 3D printing is now being used for high-value applications rather than to make prototypes or to experiment. Today, 3D printing is being used to build everything from tiny but crucial components for aircrafts to entire houses.
3D printing market: how much is the industry worth?
The value of the global 3D printing market varies wildly depending on what report you look at, but they all agree growth has started to accelerate and that this trend will continue for at least the next few years.
The Wohlers Report 2018, widely regarded as one of the most insightful annual analyses of the 3D printing market, suggests the value of the global industry rose to $7.3 billion in 2017 from just over $6 billion in 2016. The report, produced by Wohlers Associates, suggests that value will more than double to $15.8 billion by 2020 and go on to reach $23.9 billion in 2022 and $35.6 billion in 2024.
Smithers Pira, a UK-based market research firm interested in the packaging and print industries, believes the industry was worth $5.8 billion in 2016 and predicts it will experience average annual growth of around 23% until 2027, when it could be worth $55.8 billion. It says increased adoption by larger industrial and commercial businesses is expected to contribute the majority of growth, particularly as these firms use them for higher-valued applications compared to those used by hobbyists or small, niche businesses.
More recent data from Statista suggests spending on 3D printing worldwide will amount to around $14 billion this year, with expectations for that to climb to $23 billion by 2022. It believes around half of all spending will be on 3D printers by 2022, with the rest spent on other major inputs like materials, software and servicing.
A report released in late 2018 by Deloitte estimates the value of the 3D printing market to be considerably lower than other reports but this is because it only takes publicly-traded companies into account. Deloitte estimates the value of the market was $2.4 billion in 2018, up from $2.2 billon in 2017 and $1.9 billion in 2016. It forecasts the market will be worth $2.7 billion in 2019 and $3.1 billion in 2020. That is a nominal amount considering about $12 trillion is spent around the world on manufacturing each year, but 3D printing is now comfortably growing faster than the wider industry.
3D printing: why is growth accelerating?
There are multiple reasons why annual growth has broadly doubled from just a few years ago. There is now a wider range of 3D printers capable of building more complex products from a wider array of materials at much faster speeds. In a nutshell, the technology now boasts better economics and can be used for a wider range of applications.
The early days of 3D printing were largely confined to using plastic and polymers. But, according to Deloitte, 3D printers are now capable of producing products using twice as many materials than in 2014. The most significant new material to have been introduced is metal.
'Plastic is fine for prototypes and certain final parts, but the trillion-dollar metal-parts fabrication market is the more important market for 3D printers to address,' according to Deloitte. Plastics are still the most commonly used material in 3D printing but its share of the market declined heavily in 2018, when just 65% of 3D printed products were made from plastic compared to 88% the year before. That is because more companies have started to use better quality materials. Metal is thought to have been used to make 36% of all 3D printed products last year compared to just 28% in 2017. If that rate of adoption continues then metal could overtake plastic as the most widely used material in 3D printing by as early as 2020 or 2021.
What materials are needed for 3D printing?
Those looking to gain exposure to 3D printing should consider those stocks that produce the vital feed material that 3D printers need. Oil refiners and chemical companies make the plastics and polymers, such as acrylonitrile butadiene styrene, polylactic acid and polyethylene terephthalate glycol-modified.
The metals come from mining firms and industrial metal companies. Smithers Pira states aluminium, bronze powders, steel, cobalt-chromium compounds and certain titanium alloys are the most commonly used metals in 3D printers at present, although they are likely to start using more types of metal in the near future.
The process of 3D printing was far too slow in its initial years for a world that strives for scale and the ability to make large volumes at fast speeds. Deloitte states 3D printers are, generally speaking, twice as fast in 2019 than they were in 2014 but admits this varies depending on the complexity of the shape, material being used and the quality of the work.
They have also become capable of building larger objects, making it capable of creating more products. A standard high-end printer can now create objects with a volume of up to 27 cubic litres, compared to just one cubic litre from a typical printer in 2014, according to Deloitte.
Some have successfully taken this to the extreme. For example, some companies are using large, transportable printers that can build digitally-designed houses by printing layer-by-layer of cement. Being able to create larger objects is highly significant as it means companies don’t have to print a series of smaller objects and combine them into a final product, speeding up the process and reducing costs.
The amount of companies involved in 3D printing is on the rise. The latest Wohlers report said there are around 177 companies that make and sell industrial 3D printers compared to just 135 in 2018 and less than 100 in 2016. The number of big-name companies experimenting with 3D printing is also climbing, particularly in areas like aerospace, automotive and healthcare.
Airbus, Boeing, United Technologies Group, BMW, Jabil and Oerlikon are among the corporate giants tapping into the benefits of 3D printing, such as being able to make bespoke components on-site or lighter-weight parts. Being able to produce spare parts for an aeroplane or factory equipment is a major advantage as this reduces reliance on suppliers and the need to have components shipped-in and stored.
Smithers Pira estimates businesses spent over $5 billion on industrial 3D printers in 2018 compared to just $400,000 in 2016, while sales of smaller, home-based printers have declined.
The software and data that operates 3D printers is just as important as the printer itself. If 3D printers are to reach their full potential and become fully integrated into wider manufacturing lines, then they need to be fed data to optimise the process from initial design to the end product. If a company is using multiple types of 3D printing or blending it with other types of manufacturing, they will endeavour to make sure they all use the same software and data, which will act as a backbone of the entire operation. This will also require firms to think about how they gather and store data.
