The 3D printing industry is made up of companies that provide products and services capable of manufacturing a range of products. 3D printing, also known as additive manufacturing, creates physical objects from digital designs. The printing process works by laying down thin layers of material in the form of liquid or powdered plastic, metal, or cement, and then fusing the layers together. Though still too slow for mass production, it is a revolutionary technology that has the potential to disrupt the manufacturing logistics and inventory management industries. The 3D printing industry is comprised of only a handful of companies, including players such as Proto Labs Inc., Faro Technologies Inc., and Desktop Metal Inc.

The industry is so young that it has no meaningful benchmark index. But the performance of these stocks can be compared to the broader market as represented by the Russell 1000 Index. These stocks have not performed well. Stratasys Ltd. (SSYS), the best performing 3D printing stock, has dramatically underperformed the Russell 1000, which has provided a total return of -12.5% over the past 12 months. This market performance number and all statistics in the tables below are as of Sept. 20, 2022.

Here are the top three 3D printing stocks with the best value, fastest sales growth, and the best performance.

These are the 3D printing stocks with the lowest 12-month trailing price-to-sales (P/S) ratio. For companies in early stages of development or industries suffering from major shocks, this metric can be substituted as a rough measure of a business's value. A business with higher sales could eventually produce more profit when it achieves (or returns to) profitability. The price-to-sales ratio shows how much you're paying for the stock for each dollar of sales generated.

Best Value 3D Printing Stocks
	Price ($)	Market Cap ($B)	12-Month Trailing P/S Ratio
Stratasys Ltd. (SSYS)	15.49	1.0	1.6
3D Systems Corp. (DDD)	9.00	1.2	2.0
Proto Labs Inc. (PRLB)	37.49	1.0	2.1

Stratasys Ltd.: Stratasys offers 3D printing solutions, such as 3D printers, polymer materials, a software ecosystem, and related parts. It serves a variety of industries, including aerospace, automotive, consumer products, and healthcare. On Sept. 13, Stratasys completed the merger of its MakerBot subsidiary with Ultimaker, which offers platforms used to make 3-D printers. Ultimaker is backed by NPM Capital. The merged company will keep the Ultimaker name and focus on providing solutions, hardware, software and materials to the industry. NPM Capital will have majority ownership of the new company at 53.5%, and Stratasys will own 46.5%.
3D Systems Corp.: 3D Systems provides 3D printing solutions. The company offers a range of hardware, software, and materials designed for additive manufacturing. Its products and services are used in a variety of industries and sectors, including aerospace, automotive, semiconductor, healthcare, and more.
Proto Labs Inc.: Proto Labs is an e-commerce-based company that provides digital manufacturing services. It offers 3D printing, injection molding, CNC machining, and sheet metal fabrication. On Aug. 5, Proto Labs announced financial results for Q2 2022, the three-month period ending on June 30, 2022. Net income fell more than 80% to $2.6 million from the prior-year quarter while revenue rose 3.1%.

These are the 3D printing stocks with the highest YOY sales growth for the most recent quarter. Rising sales can help investors identify companies that are able to grow revenue organically or through other means and find growing companies that have not yet reached profitability. In addition, accounting factors that may not reflect the overall strength of the business can significantly influence earnings per share. However, sales growth can also be potentially misleading about the strength of a business, because growing sales on money-losing businesses can be harmful if the company has no plan to reach profitability.

5 3D Printing Stocks to Consider in 2022

An in-depth look at the leading 3D printing stocks in the U.S stock market this year. Here’s what you need to know.

By Nicholas Rossolillo – Updated Jul 11, 2022 at 2:42PM

Back in the early 2010s, stocks were booming for 3D printing -- also known as additive manufacturing, a computer-controlled process in which three-dimensional objects are made. But the boom was followed by a bust as many pure-play 3D printing companies didn't immediately deliver on lofty expectations.

Rumors of the manufacturing technology's demise are clearly premature. These days, 3D printing is a high-growth niche that is steadily reshaping the manufacturing and industrial sectors. Some estimates point to a doubling in annual revenue from additive manufacturing between 2022 and 2026. Even growth investor Cathie Wood has launched a fund focused on manufacturing tech, The 3D Printing ETF (NYSEMKT:PRNT), via her company ARK Invest.

Here's what you need to know about 3D printing and additive manufacturing stocks for 2022:

Investing in 3D printing stocks

The manufacturing of products in all corners of the economy is being revolutionized by 3D printing, from healthcare equipment to metal fabrication to housing construction. It's invading so many sectors that tech giants such as Microsoft (NASDAQ:MSFT), Autodesk (NASDAQ:ADSK), and HP (NYSE:HPQ) have launched products aimed at 3D printing and additive manufacturing. Other engineering and software outfits such as Dassault Systemes (OTC:DASTY), ANSYS (NASDAQ:ANSS), and Trimble (NASDAQ:TRMB) have also gotten involved in 3D printing technology.

Here are five key players to consider for 2022 that are a more focused bet on 3D printing:

Data source: YCharts. Market cap as of April 19, 2022.
Company	Market Cap	Description
Desktop Metal (NYSE:DM)	$1.3 billion	Recent IPO that focuses on metal fabrication technology.
Stratasys (NASDAQ:SSYS)	$1.5 billion	One of the original 3D printing pioneers, with a wide array of printers and supporting design software.
Xometry (NASDAQ:XMTR)	$1.9 billion	A manufacturing marketplace, including access to on-demand 3D printing services.
3D Systems (NYSE:DDD)	$1.9 billion	Another original 3D printing pioneer and the largest pure-play stock on 3D printing technology.
PTC (NASDAQ:PTC)	$11.7 billion	A manufacturing technology provider with a suite of software and related services for industrial businesses.

1. Desktop Metal

This company is a recent entry into the 3D printing space after going public via a SPAC at the end of 2020. The stock has been a terrible market underperformer since then, losing three-quarters of its value as of spring 2022. However, Desktop Metal could still be a promising investment for the long term.

As its name implies, Desktop Metal develops 3D printing hardware and accompanying design software for metal and carbon fiber parts. The company's smaller systems can handle prototyping and one-off parts, and larger printers are production grade-designed for manufacturing facilities. Desktop Metal serves companies operating in automotive, consumer goods, and heavy industrial equipment businesses.

Despite a tenuous start as a public company, Desktop Metal was actually increasing revenue at a torrid triple-digit pace in 2021. Gross profit margins are thin, and the company generated a steep net loss, but that should improve over time as the business scales its operation. Desktop Metal also has several hundred million dollars in cash and investments to fund its expansion. It used some of these funds to acquire additive manufacturing peer ExOne at the end of 2021.

2. Stratasys

Stratasys was part of the early 2010s 3D printing stock boom and bust, but its business has endured. Sales took a dip early in the COVID-19 pandemic but are rebounding as the Israel-based company picks up new manufacturing contracts.

Stratasys serves a diverse set of customers, including aerospace and automotive parts manufacturers, medical and dental companies, and makers of basic consumer products. In addition to a wide array of 3D printer models, Stratasys develops software to help users accelerate the time between design and final printing.

It isn't the highest-growth name on this list, but Stratasys is profitable (on a free cash flow basis) and has more than $500 million in cash and investments on its balance sheet, as well as no debt. Management thinks its payoff from years of research and development into additive manufacturing will accelerate in 2022.

3. Xometry

This is another newcomer to public markets. Xometry completed its initial public offering (IPO) over the summer of 2021, raising almost $350 million in cash in the process. As is often the case with new IPOs, the stock has underperformed since then. It has lost over half of its value from the time it started trading on public markets, but the business itself is rapidly growing.

Xometry is a marketplace for on-demand manufacturing of prototyping and mass production. It has a network of more than 5,000 suppliers that companies can call on to meet their fabrication needs. Among the suppliers on the Xometry platform are 3D printing companies, injection molding, and automated machining. The company reported having more than 28,000 active buyers utilizing its platform at the end of 2021.

Although it isn't profitable yet, Xometry's unique approach to the 3D printing and additive manufacturing industry is growing fast. Like other names on this list, it has a sizable war chest of cash and short-term investments that it can spend on research and marketing as it tries to attract more suppliers and buyers to its marketplace.

4. 3D Systems

3D Systems was another early player in the 3D printing industry, and while it suffered through the boom-and-bust period of the early 2010s, its business has held steady for much of the past decade. After a brief dip during the early days of the pandemic, 3D Systems is back in growth mode.

The company develops printers and design software for all sorts of materials and industries (medical device makers, dental labs, semiconductor designers, aerospace, and automotive manufacturers). It claims leadership among independent 3D printing companies (as measured by sales). As the 3D printing industry expands in the coming years, 3D Systems thinks it will be able to attract lots of new business with its extensive experience and global reach.

As an established tech outfit in the manufacturing sector, 3D Systems offers investors the prospect of more stable growth, along with profitability. It also has a large net cash position from which it can consolidate its lead in 3D printers and software technology.

5. PTC

By far the largest company on this list, PTC is a longtime technology partner of manufacturing and industrial enterprises. Fast approaching $2 billion in annualized sales and highly profitable, PTC has all the tools needed to digitally transform industrial businesses.

Besides 3D printing computer-aided design software (ANSYS is a peer and software partner that also operates in this space), PTC specializes in augmented reality, industrial IoT (Internet of Things), and product life-cycle management software. Most of its revenue is subscription-based (including its Creo software that enables 3D printing), making for a stable and steadily growing business model that generates ample cash flow. PTC puts spare cash to work developing new products for its partners and makes bolt-on acquisitions of other software companies that enhance its overall portfolio.

As a larger company, PTC won't be the fastest-growing stock in the additive manufacturing and 3D printing space. However, the company has established itself as a leader in industrial technology and should be a primary beneficiary as the production of manufactured goods gets more efficient.

The future of 3D printing

Manufacturing technology is making inroads throughout the global economy by reducing the cost of production and localizing and speeding up the time it takes to deliver customer orders. This is far from mere hype. Nevertheless, as is the case with all technology investments, progress won't go straight up. Expect twists and turns in these stocks as they develop new methods to design and make products.

If you decide to invest, do so in a measured way. Maintain a diversified portfolio, be wary of stocks benefiting from investor over-optimism, and always leave spare cash to invest more when there are inevitable dips. Given enough time -- years and decades -- investing in 3D printing could eventually provide a big payoff.

Production of 3D printers in Europe. What blond birch trees are silent about ... / Sudo Null IT News market, with whom it is only possible (whom I did not meet - my beloved partner met), after which

decided “That's it, let's go! We are going to 3D”
Being, on the one hand, a dreamy and enthusiastic person, but on the other hand, a cynical and prudent businessman, before diving headlong into the industry, it was decided to shake the pool of 3D printer manufacturers vigorously before choosing an accent for future distribution.
I won’t dwell on this stage too much, I’ll just say one thing: they were “shaking” with uncomfortable questions, meetings, real tests, weighted price comparisons - companies from the top 10 brands that occupied the media space, the low-level segment was not considered in principle due to strictly defined competence distribution groups.

And so, in April of this year, we were thrown by a wave in the Spanish town of Navarre, where I personally saw the European level of assembly of 3D printers at factory bq , which I wanted to share with you, not forgetting the “cherry” at the end of the story.

The town where the factory of the company bq is located, producing Witbox printers, as usual for Europe (and I have been to many factories in Europe and China), is very small and expectedly romantic:

In the morning after arrival to the city - we went to the factory ourselves, the meeting was somewhat chaotic, because on the same day, more distributors from Italy and Colombia arrived at bq.
It was all the more interesting for me to see the production through the eyes of a person for whose arrival there was no time to prepare (by building the Potemkin villages according to a custom known in Russia).

What can I say, after the Chinese cold, poorly lit workshops with girls wrapping themselves in warm clothes with belongings on the desktops, the European assembly is always like oil for the soul.
Immediately striking: Space and Cleanliness

We were taken step by step through the entire production, allowing us to take general photographs without zooming in.
Below are the most interesting of them, in my humble opinion, with a few comments:

At the first stage in production, tables with guides are assembled, fixed inside the platform, and then the control electronics are fixed.
Under each printer, there is CHECK list , in which the assemblers mark the operations performed, and the intermediate testers check the operability or lack of it at a certain stage (these are white sheets inside each Witbox printer in the photo):

External electronics - installed by blue collar guys on this line. they also test this electronics:

In the next room we found FANUC Robodrill - in fact a large 3D printer, but in a non-additive manufacturing format.
Seeing it, the engineer of our company, who came to study, trembled and began to excitedly whisper in my ear that “this thing is worth more than anything that is here,” which made me worry for no apparent reason.

Our question: "What is it used for?" was shown to us on a stack of these spare parts stacked side by side.
This is a snap-box for the electronic filling of the printer, the Spaniards in bq grind it on their own:

Then followed the phrase that made me think:
“We used to print these boards on our own Witbox 3D printers, but with an increase in production it became absolutely unjustified in terms of time costs”

Guys from Russia, manufacturers of 3D printers, often boasted to me that many of the spare parts for their "gadgets" are produced on their own printers.
It can be concluded that the number of units produced is hardly large in these specific cases and can indirectly indicate a small amount of accumulated production experience.

Next to FANUC is the Laser Cutting Plotter , which makes the outer bright panels for the future printer.
Maybe I called it wrong, but for me, an office rat, such large machines, before my eyes turning huge sheets into beautifully shaped, ready-to-install external panels with a logo on board, always make a fascinating impression.

Even before the panels are installed, each printer starts to print a calibration pattern (below you will see a number of these printing Witboxes).
If the test is successful, the printer goes to packaging. At the same time, the model printed on this particular printer MUST be put into the box.
Doesn't pass the test - they make an additional adjustment to the victorious one.

Here I trembled again and for a long time fascinated looked at the bluish backlight of the print area, appreciating with peripheral vision an elegant solution for laying PLA plastic without the flip over the top, which is standard for most devices of this kind:

Printers that have passed the print test are equipped with external panels (yellow, black or white):

to play around” to our engineer, who became very close to like-minded Spanish engineers during the short time of our visit):

I liked EVERYTHING on the final packaging.

1. Double box - beautiful inner and outer shipping:

The guys from bq said that the printer in this package can withstand a fall from a height of 1 meter:

- Reel PLA - plastic (two for Witbox printer with two extruders)
— 4GB SD - card

— Additional HOT END — extruder nozzle (I almost burst into tears when I saw it, and girlishly framed the photo as a token of sincere gratitude for such attention to customers):

- Instructions and warranty card for 2 years operation

shipments to Madrid, main warehouse bq

after the mandatory palletization procedure:

In the morning - this (printed on a Witbox 3D printer, as evidenced by the inscription on the board) forklift

… will load them onto a truck bound for sunny Madrid, so that the “swallows” will then fly around the world…

Koda. Curtain.

Cherry

(which was promised above):

Why is the actual post placed in the hub Open Source ?

At the end of our trip we asked the Europeans:

Why are you, an absolutely successful IT company, second in the market in Spain in sales of smartphones and tablets, investing in the production of 3D printers?
Why are you so actively sharing information with us, investing your time, effort and money, including in the Russian market?
Are you not afraid that the #Chinese will come and eat you? Aren't you afraid that manufacturers in Russia will be able to knock out all Europeans and Americans from the 3D printer market?
Are you confident in the long term of your strategy?

The answer of Mario and Antonio from bq threw me into complete confusion:

We are NOT afraid of the Chinese.
The exact scheme of the WitBox 3D printer with all the spare parts is posted on our website:

Download, do it yourself.

We are deeply convinced that this data should be available so that the entire engineering community can hot-start the printer to the ideal, and the culture of production, its level, believe us, is extremely difficult to repeat.
There is nothing to fear here.
