Trying to 3D-print a combustion engine in plastic introduces all kinds of problems, though. You have to accept certain limitations of the technology right off the bat.

However, 3D printing a single car engine block could take up to 300 hours. Therefore 3D printing an engine is not the best option if mass production is not the intended purpose.

But rather than actually 3D printing an engine, designers 3D print the molds that will define the shape of their engine blocks.

From prototypes through to final components, tools, and spare parts, 3D printing is one of John Deere’s major assets in its quest to be a more digital and agile organization.
