Although most 3D printers are expensive, recently there has been a steep decline in the prices of 3D printers. This has led to it going from being a niche industry novelty to a hobbyist’s item. There are many affordable 3D printers that are available for much less than they are worth, if we take all its production capabilities into account. Companies have also realized the potential of a consumer market for 3D printers and as such have been aggressively courting enthusiasts with cheaper and better models. There are many communities formed around these enthusiast groups which are active on the internet set up to share projects and ideas and new possibilities. One of the most popular is known as RepRap. Its goal is to produce a free and open-source hardware (FOSH) 3D printer licensed under GNU Public License. These printers are also intended to be capable of replicating itself printing many of its own plastic parts to create more machines.
