Production additive manufacturing (AM) was once something to look forward to, a future application of 3D printing technology. Early adopters of 3D printing for rapid prototyping saw its value for design iteration and product development, but the material choices and systems were too limited to consider those early prints as final production parts. But times have changed. Where there was once just one type of 3D printing, there are now seven distinct families of processes and many, many machine suppliers. AM’s material portfolio is growing, adding new metal alloys, polymers and even composites all the time. Software is making the process more consistent and reliable, while also enabling next-generation designs that only additive can make. Production AM has officially arrived.
