3D printing has become very important in the world of STEM in recent years. It uses user input designs of a certain figure or structure with specifications of all kinds and then it uses lasers to carve out a sculpture of the design. Previous technology only allowed for 2D prints of these designs such as inkject and somewhat 3D prints using Microextrusion which isn’t highly Accurate as shown in the image above. It is highly beneficial for societal developments. Laser Printing has allowed for designs to be implemented in medical fields through the creation of prosthetic limbs, and even NASA engineering to create launch vehicles that are less complex in physical structure, but more complex internally because of the improvements in software (spacenews.com). Laser Printing has allowed for trial and error operations to occur. Before, you couldn’t do such process because the images were in 2D. Furthermore, its cheap for large companies to create working designs that facilitate the experimentation process while trying to improve certain programs. “It also allows the company to revise vehicle designs quickly, without sunk costs in tooling tied to certain designs.”However, although Laser Printing has its benefits in such practices, it has harmful effects if not regulated. According to wikipedia.com, there have been numerous designs on printable, working 3D guns. For example, “In 2013 a Texas company, Solid Concepts, demonstrated a 3D printed version of an M1911 pistol made of metal, using an industrial 3D printer.6” This is highly harmful because as of right now, the government is struggling to develop a solution to gun control. Public access to 3D printing may jeopardize this process because there will be massive printing of these guns. There will be large quantities of illegal guns that aren’t processed because people won’t have to go through backgrounds checks to have a license to purchase a weapon. Hopefully, there won’t be a need to control the access to 3D printing for these reasons. 3D will be the main source people will go to bring their designs to live and becomes better problem solvers by having hands on experience with their design.
