Wohlers Report 2022 Finds Strong Industry-Wide Growth

Wohlers Associates, the well-known additive manufacturing consultancy firm, and close ally of both MatEdU and TEAMM, recently acquired by ASTM International, released its annual report: Wohlers Report 2022.

MatEdU News and AM News (from our sister organization TEAMM) have both published details from the report over its many years of serving the AM industry (links below). The annual report focuses on the state of 3D printing and often highlights important advances within materials science. 

Key takeaways from the 425-page 2022 report show the additive manufacturing industry grew by 19.5 percent in 2021, which is up from 7.5% growth in 2020. This is largely attributed to a sustained, global recovery from the COVID-19 pandemic.

Polymer Powder

As the above image shows, from the report, “As the technology and industry mature, a growing number of companies are using AM for custom products and series production, according to the new report. A sign is the growth of polymer powder consumption in 2021, which grew by 43.3% to overtake photopolymers as the most used AM material.”

The materials section digs in the companies producing new materials or modifying materials for industry needs. Many of these smaller, nimble materials manufacturers are often of interest to academic partners within the National Science Foundation network for their research projects and community initiatives. 

3D Printing Materials

Some useful examples from the materials chapter:

  • Taulman3D offers t-glase, a tough, clear PET material, which has been cleared by the Food and Drug Administration for food contact and containers. TreeD makes a range of ‘exotic’ filaments, including clay-filled and bone-like materials.
  • Materials provider Proto-pasta creates filaments in brass, bronze, copper, iron, or steel powder with a PLA binder. ColorFabb of the Netherlands produces a variety of metal-filled PLA filaments. Parts can be polished, tarnished, and rusted like traditional metal parts.
  • Some suppliers are producing metal-filled filaments to create a metal part… BASF announced its Ultrafuse filament. Many small and large printer manufacturers, such as BCN3D, Desktop Metal, and Markforged have integrated this capability into proprietary systems.

Although the report section on materials and processes is a favorite here at MatEdU News, it also covers almost everything you need to know to stay informed about additive manufacturing in the USA and around the world — one of the reasons it is called the “Bible of 3D printing.” 

Here are some of the new and expanded features of Wohlers Report 2022:    

  • scaling AM into production;
  • workforce development and sustainability;
  • Women in 3D Printing;
  • ground-breaking R&D programs;
  • reports from industry experts in 34 countries; and
  • the future of AM

More information on Wohlers Report 2022 is available here.

As mentioned above, here are three recent posts from MatEdU News and TEAMM:

  • Wohlers Associates Report on Additive Manufacturing Post-Processing – Materials Education (MatEdU)
    • Post-processing is one of three major phases of producing 3D-printed parts. According to research conducted for Wohlers Report 2021, nearly 27% of the cost of producing AM parts comes from post-processing. The study involved input from 124 service providers in 27 countries. The following chart presents the cost segmentation between pre-processing, printing, and post-processing among companies that offer both metal and polymer AM.

Keeping Up with Materials Science Research and Trends Impacting Education and the Workforce

In late 2021, Mel Cossette, Executive Director and Principal Investigator for the National Science Foundation’s Advanced Technological Education-funded Online Instructional Resources for Material Science Technology Education (home of MatEdU News) spoke about Industry 4.0 and what it means for the manufacturing workforce.

The three biggest trends to watch, according to many of these reports and links, include:

  1. Using artificial intelligence (AI) to create new materials, known as “Generative AI” an engineer enters project parameters and the software creates multiple versions. It is like putting 1,000 (or more) materials scientist brains against a question or idea and speeding up the process of discovery. 
  2. Materials advances in biological areas from pharmaceutical (3D printing personalized medicines) to implants to research (that will undoubtedly lead to more new areas where materials will guide healthcare). 
  3. Sustainability in Materials Science is the last major trend we spotted in this exploration. Although there are many other big changes coming to the world of materials, finding a way to combine Industry 4.0 concepts with the Circular Economy (aka sustainability) is crucial to smart science.

Industry 4.0, as a quick refresher, is shorthand for the “Fourth Industrial Revolution” and sometimes abbreviated as 4IR. It has given and is currently providing innovation on an unprecedented scale, including robotics, artificial intelligence, 3D printing (additive manufacturing), biotechnology, and nanotechnology (post on a Micro Nano partner site highlighting growing in materials scientist jobs), to name but a few. Research and trends around Industry 4.0 frequently include how materials science is influencing this larger trend.

Starting with the first trend and speaking to Mel Cossette’s insights about how manufacturing jobs are building our future, Generative AI for New Materials advances, is the focus of this Redshift by Autodesk piece: AI in Manufacturing: How It’s Used and Why It’s Important for Future Factories.

One of the top resources for keeping up with current research and trends in materials science and connected industries and niches is the World Economic Forum. There is a free level account and it grants you access to the many ways that they curate and then organize data on a wide range of topics impacting the world’s economies. 

We did a search on materials science and here is a glimpse of the many posts that they pull into what they call “Transformation Maps.” This chart is interactive and allows you to see related concepts and topics and to click into those sections. It is robust and extremely helpful if you are trying to get a sense of the space. Hang on for a big list of resource and trend links below…

The Top Tech Trends post by McKinsey shows materials advances will impact many industries: 

Graphene Research at Rice University

“Developments in materials science have the potential to transform multiple market sectors, including pharma, energy, transportation, health, semiconductors and manufacturing. Such materials include graphene – a single layer of carbon atoms arranged in a honeycomb lattice configuration, which is around 200 times stronger than steel, despite its incredible thinness. It is also a very efficient conductor and promises to revolutionize semiconductor performance. Another is molybdenum disulfide – nanoparticles of which are already being used in flexible electronics.”

McKinsey also highlights that a bio revolution is underway thanks to these materials advances: “Propelled by AI, automation and DNA sequencing, the bio revolution promises the development of gene-therapies, hyper-personalized medicines and genetics-based guidance on food and exercise.”

These changes also mean job opportunities, and that is why the National Science Foundation funds a wide and deep range of advanced technological education projects like MatEdU and the Micro Nano Technology Education Center (MNT-EC) (with its many partners including InnovATEBIO profiled here in 2021) to build the curriculum and training modules needed by students and industry. Biotech Careers offers a detailed look at that intersection where trends meet job opportunity. The MNT-EC Industry Partner page gives an idea of how NSF projects pull in companies looking to be part of the work to build educational programs that meet student interest and employer needs.

Materials advances through the methods mentioned above only give a glimpse into part of what makes rapid iterations work — researchers cannot iterate without testing and it happens in a big way through 3D Printing. ASME recently posted: Metamaterials Expand Possibilities in Biomedical Engineering and it confirms, at least in part, how metamaterials are fabricated quickly using additive manufacturing (aka 3D Printing).

The National Library of Medicine: National Center of Biotechnology Information has a large volume (of course) of materials-oriented nanobio medical and health articles. Here are a few:

Greentown Labs is aiming to be the leading hub for startups (and the wonderful people building them) to work toward the shared goal of a sustainable, renewable future. Their relatively new Careers in Climatetech newsletter provides a glimpse into the materials science work happening, but also across clean tech / green tech science and engineering.
