American 3D Printers to Speed Up Repairs on Ukraine’s Front Lines

In Ukraine’s continued fight against Russia, the use of 3D printers has taken on an ever-growing role. The transportable, on-site, on-demand nature of additive manufacturing has proven to be a real boost to the Ukrainian war effort. Applications are varied as well with everything from frontline uses like manufacturing weapons components and drones, to the civilian sector in construction and medical care for victims of the conflict, and even using 3D scanning in an effort to uncover justice amidst the chaos. Now, it is once again safe to say that 3D printing has stepped back into service as the United States has announced the handover of several large, industrial-grade 3D printers that are capable of providing the Ukrainian armed forces with spare parts and 3D printed replacements for their battlefield equipment.

Speaking at the Center for New American Security (CNAS) think tank, US Under-Secretary of Defense for Acquisition and Sustainment William LaPlante stated that the industrial 3D printers were delivered to Ukraine last month and that Ukrainian engineers had recently completed their training on how to use the devices. “It’s going right in-theater and they’re printing all their repair parts,” explains LaPlante, highlighting the main objective for these printers – to manufacture parts for Ukrainian vehicles, aircraft and machinery on-location that can be used to make repairs much faster than waiting on traditional parts and supply chains.

While the exact type or model of the industrial 3D printers was not specified, given their large size and purpose (LaPlante mentions that the printers are the size of a small truck), we can assume that they could any number of industrial 3D printers. Some potential include either binder jetting or powder bed fusion 3D printers that are able to construct multiple parts in a single batch out of metal or ceramic, though are not always this large. Alternatively, they may include direct energy deposition (DED) printers which are often used specifically for metal-based repairs and tend to be very large.
