The progression from fire to more developed sources of artificial light was was slow, with little change until the advent of gas illumination in the early 1800s. Furthermore, the biggest change in night activity was in the workplace: artificial light enabled mills and factories to employ their workforces for longer hours. Following the increase of nighttime labor was an increase in nighttime entertainment.

3D printing is also being applied to answer medical needs. The process has already produced usable medical devices and patient-specific implants. Recently, engineers built the first 3D bioprinting production system, which might someday have the capacity to print organs and body parts from layers of living tissue. While this technology currently requires further research and development before it is ready for use, the thought of someday being able to produce necessary organs for the many people awaiting organ transplants is exhilarating.

Despite the promise of this new technology, we cannot allow ourselves to get swept up in the current of innovation without weighing the consequences. Although the positive aspects of 3D printing are enormous, there are other, less-immediate effects to consider. If we are someday able to manufacture all our goods at home, for example, what will happen to the manufacturing industry? How will the people who used to create our clothes and produce our car parts support themselves and their families?
