Massachusetts-based 3D printing company Markforged is using its new Atomic Diffusion Additive Manufacturing (ADAM) process and Metal X 3D printers to advance its futuristic “3D print farm” vision of large-scale metal manufacturing.
When Markforged unveiled its new Metal X 3D printer at CES earlier this year, we were struck by one thing in particular. Unusually for a Markforged product, it wasn’t the 3D printer itself, but the way that the company said it should be used.
Massachusetts-based Markforged, which cemented its place in additive manufacturing history when it released the world’s first carbon fiber 3D printer, the Mark One, said it had designed the Metal X to work not just as a standalone machine, but as part of a large-scale “3D print farm” consisting of tens, hundreds, or even thousands of 3D printers.
It is on these multi-printer 3D print farms that Markforged believes future large-scale metal 3D printing will take place. Given the focus from some quarters on making 3D printers bigger, Markforged’s approach stands out as a different option: rather than increase the size (or speed) of an individual 3D printer to increase its manufacturing capacity, you could instead use several 3D printers working in sync, controlled by a central system capable of assigning tasks for maximum efficiency.
It’s a daringly simple concept, one that is also followed by companies like Brooklyn-based Voodoo Manufacturing, but it’s also an ambitious one. Markforged is essentially telling manufacturers that they won’t just need a handful of 3D printers in the future—they’ll need thousands.
The Markforged Metal X 3D printer can inspect parts as they are being printed
Markforged recently released some extra information concerning its proposed 3D print farms, which the company says “will shorten development time, closing the gap between prototyping and production.”
According to Markforged, there are three key focus areas for making the concept a success.
The first of these involves using the company’s new ADAM 3D printing technology to reduce printing costs. The second involves deploying smart sensors to build a platform for the print farm, and the third involves using its enterprise-grade fleet management software, which can “optimize workflows, provide predictive analytics,” and “connect, monitor, and report results across a fleet of connected printers.”
ADAM, the 3D printing process used by the new Markforged Metal X 3D printers and 3D print farms, builds on the company’s carbon fiber printing processes, but replaces carbon fiber with 60% metal powder. The company says this new process improves “machine reliability, surface finish, final-part dimensional accuracy, and repeatability.”
“ADAM is an end-to-end process that starts with metal powder, captures it in a plastic binder (which makes it safe to handle), and then forms it into the part shape one layer at a time,” explains Markforged CEO Greg Mark. “After printing you sinter the part in a furnace, burning off the binder and solidifying the powder into the final fully-dense metal part.”
An important part of the 3D print farm project is reducing the overall cost of 3D printing for businesses—something that Markforged will absolutely need to demonstrate considering the scale of setting up one of these print farms. At present, Markforged’s desktop printers cost $3,499, but the company is working on a two-year target to make each printer in its print farms costs less than $1,000.
Part printed using Markforged’s ADAM 3D printing process
Of course, the idea behind the print farm is to have huge numbers of these printers running simultaneously. Assuming that the resulting high turnover of parts could generate suitable revenue, this would then hypothetically justify the investment in a sintering furnace, required to burn off the plastic binder used in the ADAM 3D printing process. A “full stack production furnace,” which can handle the output of 500-1,000 3D printers in a print farm, costs around $800,000.
When making quick prototypes, users of this new Markforged 3D printing technology could also use microwave sintering to produce pure metal parts “within hours.” The company says it has been microwaving ADAM parts with a 90-minute cycle time.
Fortunately for Markforged customers, the 3D printing company has developed its ADAM 3D printing process to work with a variety of 3D printable materials. “ADAM leverages well known MIM materials that are used in demanding, end-use applications,” Mark says. “Best of all, the process supports hundreds of metals. 17-4 Stainless Steel is the first material we will ship, but many others are in beta testing including Tool Steels, Titanium, Aluminum, and Inconel.”
Markforged’s cloud-based fleet management solution, Eiger, is used to control the many 3D printers in a print farm.
“In the next 2 years Markforged will achieve the technological leap to true digital metal manufacturing,” Mark says. “It’s time for mechanical engineering to enter the digital age.”

Direct metal writing uses semi-solid heated metals forced through a 3D printer nozzle
A team of engineers has developed a new way of 3D-printing metals that could improve on existing, laser-on-powder based methods. It relies on using semi-solid metals that are solid at rest, but can flow when force is applied, making it possible to move through the nozzle of a printer. Researchers at Lawrence Livermore National Laboratory (LLNL) hope that the process could lead to higher-quality and lighter metal parts.
The team, along with collaborators from Worchester Polytechnic Institute, call the new approach “direct metal writing.” Rather than starting with a metal powder as in currently popular 3D-printing techniques like selective laser melting (SLM), a block of metal engineered to be shear thinning is heated until it becomes semi-solid.
Being shear thinning means that it acts a little bit like paste when heated – solid metal particles are surrounded by a liquid metal and the solids clump up when at rest, but when force is applied, those solids break apart and flow along with the liquid metal. The effect can be seen in the video below.
These properties allow the metal to flow through a nozzle. The printed object then hardens as it cools, leaving fewer potential defects than with other flash melting techniques like SLM, according to the researchers.
“The main issue was getting very tight control over the flow,” said LLNL engineer Andy Pascall. “Now we’ve gotten such good control that we can print self-supporting structures. That’s never been done before.”
There is still more work to be done, however. The engineers hope to refine the process to create higher-resolution objects using materials common to industry like aluminum and titanium. A paper the team published on the advance in the journal Applied Physics Letters describes how the process worked using a mixture of bismuth and tin. The combination has a low melting point and often led to slivers of solid metal getting stuck in the nozzle, forcing the researchers to go through several iterations before getting the process down.
The researchers have already moved on to working with aluminum, which they say will be challenging because of its higher melting point, but it could be potentially attractive for creating parts that can be used in aerospace and transportation.
The role that the industrial application of 3D printing could play in transforming the production of bespoke, high-value, low-volume manufacturing in the oil and gas industry will be the focus for an event in Aberdeen in March.
The additive manufacturing (AM) seminar, organised by the Oil & Gas Innovation Centre (OGIC) and TWI, will feature industrial case studies and presentations on design, materials and process development, component manufacture, validation techniques and certification routes.
Additive manufacturing (AM) is the industrial application of 3D printing, the layer-by-layer construction of a part from a 3D model created using computer-aided design software.
The seminar on 21 March will bring together stakeholders in advanced manufacturing technologies and services in an open forum to discuss future opportunities, benefits and challenges – and crucially how the oil and gas industry can robustly adopt AM technologies.
OGIC is an innovation support organisation that helps companies to access research and development capability within Scotland’s university community. By matching companies with the appropriate academic partners and co-funding projects, OGIC accelerates innovation to address the oil and gas industry’s exploration, production and decommissioning challenges. OGIC’s work directly contributes to the twin goals of maximising economic recovery from the UK continental shelf and supporting the development of the supply chain through bringing new products and services to the UK and international markets.
TWI specialises in innovation, knowledge transfer and in solving problems across all aspects of manufacturing, fabrication and whole-life integrity management. Its experience in supplying services and innovative solutions for the oil and gas sector stems back to the beginning of the North Sea oil industry. In metal AM, it works with a diverse range of metals in both wire and powder form, fusing them together using lasers, electron beams and electric arcs. TWI offers comprehensive AM business solutions from initial feasibility assessment into full rate production.
Additive manufacturing represents a step change in the flexibility of production, allowing businesses to design and make better products, enter new markets and develop new business models, react more quickly to changing demands, and explore the possibilities of digital manufacturing.
Ian Phillips, chief executive of OGIC, says, “The opportunities which metal additive manufacturing (AM) present for innovation within the oil and gas industry have yet to be fully realised. The rapid growth of the technology has seen it used for industrial production in markets including medical, dental, aerospace, automotive, consumer products and oil and gas. Metal AM technologies benefit these sectors by offering design freedom and a correspondingly increased capacity for innovation and reduced time-to-market in product development.”
“TWI has been supporting this transformative technology’s growth and acting as a key protagonist in its industrialisation for the last 25 years. This seminar will offer important insights on design, materials and process development, component manufacture, validation techniques and certification routes,” adds Phillips.
The “Additive Manufacturing – an oil & gas revolution?” seminar will take place on Tuesday, 21 March. To register visit the events section of the www.ogic.co.uk website.
