The slicing fringe of additive manufacturing presents a world of prospects for firms seeking to remodel their manufacturing processes and create new merchandise. However firms that need to faucet into that world have historically needed to make investments enormous sums of cash into the most recent 3D printing machines after which work out learn how to combine them into their operations.
That’s a tricky promote contemplating 3D printers can wrestle with throughput and consistency for a lot of industrial purposes.

Now, VulcanForms, based by Martin C. Feldmann MEng ’14 and MIT Professor John Hart, is providing digital manufacturing as a service for firms to construct industrial merchandise at scale. The corporate assists clients with supplies choice and product design, after which crafts a scalable manufacturing workflow in its manufacturing foundry.
On the coronary heart of every of these workflows is a proprietary laser powder mattress fusion (LPBF) metallic 3D printer that makes use of an array of finely choreographed laser beams to supply excessive efficiency metallic elements with complicated designs. The printers are built-in with VulcanForms’ machining, robotics, and postprocessing gear by means of a digital thread that additionally screens elements as they’re produced.
“Regardless that LPBF expertise is well-established for a number of purposes together with jet engine gas nozzles and orthopedic implants, it’s barely scratching the floor of the chance,” Hart says. “VulcanForms sees an incredible market alternative to understand additive manufacturing at industrial scale and combine it with a digital manufacturing system.”
VulcanForms is at present producing elements for firms within the medical, protection, semiconductor, and aerospace industries, turning designs into completed elements in a matter of days. The founders say VulcanForms’ high quality exceeds trade requirements with supplies like titanium in addition to nickel-based and superior metal alloys.
VulcanForms is at present finishing its first two digital manufacturing amenities in Devens and Newburyport, Massachusetts. When it’s carried out, the Devens facility will home a number of dozen of the corporate’s additive manufacturing methods along with having postprocessing capabilities. The founders say these methods will make Devens the highest-throughput metallic additive manufacturing facility on this planet. The Newburyport facility focuses on precision machining, industrial automation, and meeting operations. Merging these applied sciences with a digital thread, VulcanForms is constructing U.S.-based digital manufacturing infrastructure that the founders say will outline the way in which merchandise are designed, constructed, and delivered.
Making 3D printing industrially related
Hart calls his entry into additive manufacturing serendipitous. In 2013, he was requested by a colleague to show a category for MIT’s Masters of Engineering in Superior Manufacturing and Design program.
“I don’t keep in mind what led me to suggest that the category concentrate on additive manufacturing, as a result of I wasn’t but doing analysis within the space,” Hart says. “The category was an experiment I used to discover a brand new curiosity and to faucet into the eagerness and curiosity of the scholars.”
One of many college students in that class was Feldmann, then in his first semester at MIT. The project-based class tasked college students with measuring the accuracy of 3D-printed elements, bettering their properties and contributing to lectures relating 3D printing to the core rules of producing.
“MIT throws a lot at you — extremely technical stuff however very relevant stuff,” Feldmann says. “At MIT, studying additive manufacturing wasn’t simply calculating issues. It was, ‘Listed below are [fused deposition modeling] printers, inform me what their capabilities are.’ And you utilize them and make issues. I actually loved that. It prepares one for main analysis efforts in trade and startups as a result of you need to method issues like you already know what you’re doing and have the arrogance that you will determine it out.”
After incomes his diploma, Feldmann grew to become a analysis specialist in Hart’s lab, the place he studied nanomaterials and battery electrodes. However Feldmann and Hart continued brainstorming methods to make additive manufacturing extra industrially related.
Finally they determined to construct a brand new sort of LPBF metallic printer that might allow a lot of lasers to function on the similar time, bettering throughput whereas sustaining the standard of the completed half. The pair acquired early steering by means of MIT’s Enterprise Mentoring Service.
“Our objective was to rearchitect the LPBF course of, and to do it in a means that allows a a lot larger and extra constant high quality, which we noticed to be the principle obstacle to industrialization of additive manufacturing.” Hart says.
With that mission in thoughts, Feldmann and Hart determined to take the leap and begin VulcanForms, with Feldmann primarily supporting himself for practically two years whereas he labored on the primary printer prototype. As we speak the corporate’s printers use tons of of weld tracks in every layer by means of which lasers transfer in a synchronized dance. The lasers collectively ship as much as 100 kilowatts of energy to make elements at the next decision and scale than the founders say different printers can obtain.
VulcanForms’ manufacturing foundry additionally consists of CNC machining and put up processing gear, and the founders say the corporate’s software program stack is a key differentiator.
“From the beginning, we noticed 3D printing as a cornerstone of digital manufacturing, the place the software program and {hardware} work hand-in-hand to encode and execute manufacturing directions,” Hart says. “We’ve constructed the software program that enables every half to obtain the identical temperature regionally in every voxel in every layer. It additionally permits us to maneuver shortly to the top product whereas sustaining that consistency in manufacturing.”
In the end the founders are centered on what these capabilities unlock for purchasers.
“What actually will get me excited is how we’re capable of take a buyer half and switch it into actuality in a manufacturing setting — not in a coat hanger or desk decoration setting,” Feldmann says. “Everybody in additive is simply tremendous enthusiastic about what a 3D printer can do and never how this works in a manufacturing worth stream. That’s why we have now a whole manufacturing worth stream in home. It’s why our motto isn’t ‘VulcanForms: 100 kilowatts laser energy in a printer.’ It’s ‘VulcanForms: accelerating innovation.’”
Serving to 3D printing attain its potential
Final yr, a supercomputer producer despatched VulcanForms designs for a cooling element in its processors. The titanium half, which contained dozens of microscopic tunnels, was so complicated it may solely be made utilizing additive manufacturing. As The New York Occasions reported, VulcanForms got here again with an element two days later.
VulcanForms has additionally produced medical implants, industrial tooling and tire molds, and elements for aviation and protection contractors.
Feldmann sees improvements enabled by additive manufacturing driving technological progress in quite a lot of industries.
“I don’t assume there are going to be orthopedic implants that aren’t LPBF-printed sooner or later,” Feldmann says.
That technological progress, in flip, will yield much more use circumstances.
“The one factor I’m one hundred pc positive of is the highest-value purposes for additive manufacturing haven’t but been discovered,” Feldmann says.
The corporate additionally sees the transformation of producing enabled by digital manufacturing applied sciences as a chance for the USA to enhance each financial prosperity and its ecosystem of innovation.
“VulcanForms believes that one of many biggest alternatives in the USA is rebuilding its industrial ecosystem round digital manufacturing methods,” Hart says. “Digital-first manufacturing applied sciences, together with additive manufacturing and automatic precision machining, allow extra progressive, useful resource environment friendly, and resilient provide chains. Innovation in manufacturing is the spine of the American financial system.”
