3D Printing/Additive Manufacturing 2019: Looking Back, Looking Ahead
December 18th, 2019 by Jeff Rowe
It’s almost 2020, and while many aspects of design, engineering, and manufacturing have certainly evolved in the past couple decades, the area that arguably has had the most radical changes and influence on the overall industry is 3D printing/additive manufacturing.
Editor’s Note: Since the advent of the term “additive manufacturing,” or AM, I’ve preferred it over 3D printing because I think it more accurately describes the process, so will use it throughout this article.
Up front and technology aside, an increasing number of economic analysts are predicting a recession in 2020 or 2021, but not nearly the magnitude of the Great Recession, so many of these analysts believe this next recession is not worth worrying excessively about. Interestingly, and generally, the analysts believe that newer AM equipment companies are better positioned to weather the coming storm because they have less at risk because they are smaller and tend not to go through declined business cycles. Actually, the smaller companies can often create and serve new markets better than much larger and established AM companies.

According to our favorite AM resource, The Wohlers Report 2019, Wohlers Associates tracked growth and sales of 177 producers of industrial AM systems, which are those priced at $5,000 or more. This is nearly one third more than the 135 system manufacturers reported a year ago. While industrial system manufacturers grew notably, desktop 3D printing systems (those that sell for under $5,000) saw significant decline in annual growth. The overall AM market continues to trend upward, with many new players, hundreds of millions of dollars invested, and innovative new products designed for AM that few envisioned years ago.
The Report also states that the overall materials segment of the industry saw record growth in 2018. Revenue from metals grew an estimated 41.9%, continuing a five-year streak of more than 40% growth each year. Such strong activity among materials suppliers and customers is a telling indicator of the increasing use of AM for production applications.
What Happened in 2019?
Admittedly, a lot has occurred in the AM space this year, way too much to cover here, but following (in no particular order) are some of the industry’s most significant announcements:
Although not directly related to 3D printing/additive manufacturing, per se, I thought the biggest event in the engineering software space was PTC’s acquisition of Onshape. I think this could potentially be a much bigger deal than first meets the eye and something that the rest of the traditional CAD industry will monitor with some trepidation and a sense of urgency that hopefully will shake things up in a positive way.
What’s Next in 2020 and Beyond?
Looking ahead, I think the following will be among the most significant events to occur in the AM realm in 2020:
New Materials – Although new materials are coming on the AM scene all the time, a couple of the more interesting ones suitable for production are from Carbon and 3D Systems. The new Carbon material, RPU 130, is composed of Susterra propanediol, made from corn sugar, and is a totally bio-based material that is much more eco-friendly when compared to petroleum based alternatives. The new 3D Systems material is what the company claims to be the first direct print photopolymer with thermoplastic characteristics and behavior. This new material is said to have a good surface finish with minimal need for post-processing. Material chemistry will continue to be a driving force for the AM industry.
Production Inroads – This seems to trend that has been ongoing for several years as an increasing number of industries adopt and implement AM parts on a higher volume, production basis using both plastics and materials. A barrier that in many cases hinders wider AM adoption is costly post processing that can negate some AM’s benefits.
Bioprinting – Along with mass production, custom printing for the medical and other industries, bioprinting is about to enter the spotlight, although it is in early stages of development and realistic outcomes. In other words, don’t expect to see manufactured organs on the market anytime soon, but there is a lot of capital being expended and research conducted for creating 3D-printed cells, tissues, and organs.
An Industry Divided – Although a division has existed for years between industrial/production AM machines (>$5000) and DIY 3D printers (<$5000), there is an area in the middle that combines the features, capabilities, and material choices of the so-called high-end and the affordability and relative simplicity of the low-end. Expect to see exciting things happening in the middle ground in 2020.
Industry Consolidation – The AM industry, like any other maturing industry, is subject to inevitable evolution, growth, and consolidation. Although new AM companies will continue to emerge, probably just as many existing ones will merge and be acquired in a perpetual consolidation. It’s not just larger AM companies that will acquire smaller AM companies either; don’t be surprised to see companies with no prior direct AM capabilities get into the mix through acquisition(s), much like General Electric did in forming GE Additive.
The coming year, 2020, promises to see the AM industry grow with new technologies, materials, and possibilities. All in all, an exciting future, both near- and long-term.
