And sending only one of these 3D printers to space will allow the creation of huge factories.Īpart from that, the potential applications of additive manufacturing from space are numerous. Thus, they will not just self-replicate, but also contribute to the creation of spatial manufacturing centers. Once it will be possible to use the exact same 3D printed 3D printers to create motors and electronics, these machines will allow the creation of any kind of manufacturing machine, like 3D printers, milling machines, drills or excavating machines. Ellery explained that this one might take much longer to solve. Alex Ellery, who is leading the project, said in June that the team was close to being capable of printing a fully functioning electric motor from a material similar to what can be sourced on the moon, which is a true revolution.īut there’s another prerequisite for a fully self-replication: electronics. ![]() One of the hardest parts to build when 3D printing a 3D printer is the motor. The raw material needed to create a similar mixture could be extracted from the lunar regolith, a material covering almost the entire lunar surface. This self-replication machine 3D prints a mix of materials such as plastic and iron, in varying proportions, depending on the part needed. Their goal is to then 3D print whole lunar bases, as well as conducting in-space manufacturing of satellites. A team of researchers from the Department of Mechanical and Aerospace Engineering at Carleton University in Ottawa is currently working on this. One of these machines would be sent to the moon (as a first step), and then recreate itself from lunar materials. Indeed, there are many scientists trying to find a way to 3D print a 3D printer directly in space. ![]() The most interesting one is clearly spatial exploration. But it can be used to create various 3D printed objects, for instance, consumer products, jigs and fixtures or even medical devices.Ī self-replicating desktop 3D printer is an interesting concept, but in the end, we could 3D print 3D printers for applications way more impacting. Indeed, it’s not suited yet for metal 3D printiers. Like the previous versions of the RepRap project self-replicating 3D printers, it can only 3D print some of its parts, the ones that are in plastic, but not the metal parts, nor the electronic components. It’s popular also in the education field. Why is it such a success? Its lower cost (you can find its 3D design files for free), and the ease of construction and of modification have made it a must-have for hobbyists, but also for some professionals (even if it doesn’t replace the performance of an industrial 3D printer). Two improved versions have been released since then: the Prusa i3 MK2 in 2016, and the Prusa i3 MK2S in 2017. The Prusa i3 is part of these improvements, and it’s now one of the most used 3D printers in the world. Over the years, since the RepRap project is open-source, with all the 3D models available online, there have been many iterations of this printable 3D printer from various manufacturing aficionados. You then need to assemble them yourself and to add the components who can’t be 3D printed, like electronics or metal parts (since it’s a plastic 3D printer). ![]() As they are plastic 3D printers made of plastic parts, they can 3D print some parts of themselves, just like they could totally build other 3D printed objects. Moreover, they can’t totally print themselves. They are desktop 3D printers, and thus they are limited in terms of applications compared to industrial Additive Manufacturing. The 3D printed 3D printers made by the RepRap project use the Fused Deposition Modeling FDM printing technology, with plastic 3D printing materials. Here’s a video of Adrian Bowyer assembling the RepRap project: His first functional machine, called the RepRap “Darwin”, with 50% of self-replicated parts, was unveiled in 2008. Adrian Bowyer through the RepRap project, senior lecturer at the Department of Mechanical Engineering at the University of Bath, who started his research in 2005. The first self-replicating 3D printer was invented by Dr.
