Additive manufacturing is the process of creating an object by building it one layer at a time. It is the opposite of subtractive manufacturing, in which an object is created by cutting away at a solid block of material until the final product is complete. Technically, additive manufacturing can refer to any process where a product is created by bu...
To create an object using additive manufacturing, someone must first create a design. This is typically done using computer aided design, or CAD, software, or by taking a scan of the object someone wants to print. Software then translates the design into a layer by layer framework for the additive manufacturing machine to follow. This is sent to th...
Additive manufacturing has some distinct benefits. With traditional manufacturing, the entire supply chain can take months and require an investment — sometimes millions or billions of dollars — that can only be recouped by high-volume production. With additive manufacturing, much of the supply chain’s intermediate steps are removed. “The speed at ...
Additive manufacturing has its share of challenges, too. Additive manufacturing machines are expensive, sometimes hundreds of thousands of dollars. Using them to create large lot sizes takes longer than with traditional manufacturing. And many objects that are additively manufactured require some post-processing to clean and smooth out rough edges,...
Despite all the advantages of additive manufacturing, “I don’t see traditional manufacturing being replaced,” said Roemer. That is because, aside from specific use cases, traditional manufacturing is still faster and less expensive. This is especially true when creating granular products. The smaller the layer size, the slower the manufacturing. Wh...
There are a few industries where 3-D printing parts or products makes more sense than manufacturing them traditionally. Aerospace, racecars, and the medical field are all industries where additive manufacturing can make inroads. That is because they are all industries where function is more important than price. Or where small lot sizes or customiz...
With typical additive manufacturing, machines build a 3-D object that is fixed. 4-D printing creates 3-D objects that have the ability to change or transform over time, without human interaction. There are several applications for 4-D printing. One is extreme environments, such as space, where self-configuring materials would be useful. Another is ...

Thomas Roemer is a senior lecturer at MIT Sloan in operations management and the executive director of MIT’s Leaders for Global Operations Program. He is interested in the intersection of engineering and management and the value creation during the design, manufacturing, and delivery of products. He has taught classes in operations management and s...

Jun 6, 2024 · Additive manufacturing technologies known as powder bed fusion, such as SLS, DMLS, SLM, and EBM, use lasers or electron beams to fuse powdered materials or metals layer by layer, enabling the creation of complex and durable parts. SLS (Selective Laser Sintering) uses polyamides and other plastics.
