So, you know you can print things in 3D by now right? Well you’re probably interested to find out what you could actually make with a 3D printer if you had one. Let it be known that images are worth a thousand words, so here are 10 things you can make with a 3D printer! […]
HP has introduced a Multi Jet Fusion technology for 3D printing. The multi jet fusion technology offers better speed and control compared to other printing technologies.
dual carriage system separates functions of writing and coating. Therefore each function is separately optimized for performance and productivity. The Hp technology can transform the properties of each volumetric pixel (voxel). For example, the HP Multi Jet Fusion 3D printers can print each voxel in a different color. HP expects to make millions of colors available for 3D printing. Other than color, HP expects to be able to control other properties, for example, opacity, conductivity, surface roughness, strength, elasticity, to name a few.
Defense Distributed is an open source organization that develops designs for weapons that can be downloaded from internet and 3D printed. Defense Distributed developed a fully functional gun called the Liberator. On May 5, 2013, Defense Distributed made the 3D printable files of the Liberator publicly available. Few days later, the United States Department of State cited a violation of the International Traffic in Arms Regulations and asked Defense Distributed to remove the files from the internet. On May 6, 2015, Defense Distributed sued the Department of State for violating its constitutional rights. The case is currently on appeal.
The ability to 3D print weapons raises important practical as well as moral challenges. On one hand, the Second Amendment of the Constitution states that “A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.” On the other hand the ability to download and 3D print weapons raises the issue of weapons easily falling in the wrong hands. The final outcome of the case remains to be seen.
