A characteristic that a lot of 3D printers share is having wires running all over them. These are often neatened in places with cable ties, but they still look scruffy and often get in the way of the machine moving,
Bye Bye Belts! RepRap Lorenz does not use timing belts. Instead it is driven by wire wound helically on a pulley on each stepper motor. The error caused by the change in wire angle as the helix winds 300mm of wire is about
The other day Richard Horne (a.k.a. RichRap) tweeted “It would be nice if you could chemically soften [3D print material] after printing.” This is a really clever idea – you could make a two-material print with two hard materials that stayed
I am creating a new delta RepRap called Lorenz (after the noted biologist Konrad Lorenz). It’s not yet complete, but if you want to get the CAD files it’s on Github here. This is the first of a series of posts about aspects
Amazon’s Echo Dot and its online Alexa speech recognition system for controlling the Internet of Things is pretty cool, and so it is taking the world by storm. Therefore what we need is an open-source Thing that it can control to
As I mentioned in the last blog post, we were inspired by the Feelspace Project (which gives you a magnetic compass sense, like migrating birds) to have a go at making a wearable device that would allow you to feel your surroundings – essentially extending
I was recently at the FAB 12 Meeting in Shenzhen. One of the things I saw there was a very simple and effective idea: 3D printing on fabric with RepRap to give a flexible and wearable backing. So I decided to give
I have just got back from China, where I went to talk with a company for whom we are doing some work and also to give a presentation at the Fab 12 Conference, the theme of which was artificial self-replication.
