Loving the graphics these guys use, had to share this blog from

 The Emergence of the Maker Movement

The maker movement is made up of some 135 million adults in the U.S., however, it’s more than just a U.S. movement. Maker faires that celebrate the movement have popped up in Japan, Italy, Norway, and Chile. Makers use their skills to craft items such as clothing, baked goods, jewelry, and art; contributing $29 billion to the U.S. economy annually.

From 3D printers to laser cutters—makers employ various tools to create their goods. Many gather at makerspaces where they share these resources. Makerspaces are havens for techies, artists, and entrepreneurs. Through crowdfunding, makers are able to facilitate small-scale funding for these gathering spaces.

3D printing, education and families – a interview with Chris Elsworthy, designer of Robox

By | Design, Education, Press | No Comments

A very nice interview and article by Davide Sher from

Chris talks about 3D printers in education and getting some value from “screen time” which accounts for a long periods of spare time for many children, typically in games. Chris suggests that more of this time could be spent learning the skills they will use in later life and 3D printers can be a link between the virtual creations of our children and reality. This is certainly evident in the new offering from the Tinkercad folk in Tinkerplay which is aimed directly at getting children into design by making it really fun.

Kitronik becomes a Robox Affiliated Reseller

By | News | No Comments

We are in the very early days of launching our Affiliated Reseller Scheme here at CEL Robox HQ, but already the likes of Stampede, CREAT3D and 3D-Printworld have attended the course and are almost as Robox-savvy as our very own technicians!

Another of our valued customers Kitronik attended the course last week, and they were kind enough to share their experiences on the following blog:

This is their take on the week –

Last week March 9th – 11th, Rhodri and Aaron from the Kitronik team were invited down to CEL headquarters in Portishead, Somerset, to experience first-hand the building process of the CEL Robox RBX-01, so we can pass on the best information to you and be recognised as one of Robox’s affiliated resellers!
To begin the three day course on Monday morning, we were handed a box of parts and told that by Wednesday we would have built our own fully functioning Robox 3D printer to keep. It would have been easy to laugh and walk away but here at Kitronik we like a challenge, especially when there is new technology to play with.
The first stage involved constructing the chassis of the printer casing and the mechanism on which the PEI board moves, immediately providing an insight into how simple and functional each part is, especially when compared to the prototype models also sat in the office.
Not only did we get to look at the full printer, we were also lucky enough to build the extruder and a print head from scratch, meaning we could see each stage of the filament cycle, from Smartreel through to print.
In the image above you can see a printer head that we dismantled to explore further and fully appreciate how small and precise the mechanism is (inside the silver block is even more!). As we found when given some past samples which had severe leakage, it is vital that you take extra care of the head by ‘purging’ excess material through it, ensuring no more is left in the machine to affect future prints.
Alongside building the printer, we also attended sessions on the technical aspects of the Robox RBX-01, so you can be confident that if ever you have an issue with your printer or Automaker software that needs troubleshooting, we are fully prepared to do so with as little hassle as possible; though hopefully you won’t have to encounter any technical issues anyway! As an extra bonus on completion of the course, we even got to keep the affiliate exclusive clear printer that we built, that you can expect to see more of in our forthcoming video tutorials!

unLimited Edition element14 Pi 2 Case

By | Chris Elsworthy Design Blog, Stuff and Things | No Comments

We were asked by element14 to design a case to fit the new Raspberry Pi 2

The images below show the case, it was printed in 2 halves, we paused our Robox and changed filament colour part way through each print to create this great effect.

element14 community RoadTester ‘Workshopshed’ reviews Robox

By | News | No Comments
We’re always on the look-out for reviews of the Robox 3D printer from people who understand evolving technology, and who have a real knowledge of the 3D printing industry and what is already available on the market.  It is important to us that people recognise that in our attempts to make the Robox printer future-proof things are changing all the time and some of the more innovative features are yet to come. This means the Robox should be seen as an investment piece with longevity.
Farnell Element 14 have a community of people who road test new products, comparing them against competitors, and who spend hours getting to grips with new technology.  One such RoadTester ‘Workshopshed’ has put together a comprehensive review of the Robox; the key points are below but please visit the Farnell Community for the full review and links to tests which were carried out.


Product Performed to Expectations: 10
Specifications were sufficient to design with: 10
Demo Software was of good quality: 9
Demo was easy to use: 9

    RoadTester since Mar 6, 2012
  • RoadTest: CEL Robox 3D Printer
  • Evaluation Type: Independent Products
  • Application you used the part in: Review
  • Was everything in the box required?: Yes – Everything is in the box to get printing. The link up with MyMiniFactory means that you don’t even need any CAD software to get started printing.
  • Comparable Products/Other parts you considered: Zortrax M200, Flashforge Dreamer Dual Extruders, Ultimaker 2, Cube 3 See–comparable-printers
  • What were the biggest problems encountered?: There were a few issues with the pre-release version but the printer that was returned to me has performed brilliantly. There’s a bit of an issue with the door lock not properly disengaging, interestingly that was something that was better on the pre-production model. I had a problem with my laptop shutting down mid print (as it was on batteries) and the printer paused at that point. However the printer happily restarted once my laptop had been plugged back in and the USB taken out and re-inserted. The software would not run on my older desktop machine which was annoying, luckily I had another machine to work with.
  • Detailed Review:

    A solid 3D printer that’s very easy to get up and working with. I’ve learnt a lot about 3D printing during this roadtest and hope to print lots more different things.

    This roadtest report has been delayed as it was discovered part way through that the model provided was a pre-production model. The printer was recalled and a replacement provided early in February.


    The printer is mechanically very well made, obviously a lot of though has gone into making it robust but easy to repair. The software has evolved slightly throughout the test. It is simple to work out and because of the smart cartridges it’s possible to print straight out of the box without needing to understand the different settings needed for different materials.

    Preproduction model

    There were some issues with this model and I managed to pop off the bowden tube connector whilst testing. I also had issues with the filament take up and the material not sticking to the bed. CEL were very helpful and sent me an upgraded tube and also a replacement bed. However once the fan FET popped there was little to be done other than send it back to be swapped out with a production model.

    Production Model

    Cosmetically the printer looks very similar but there are quite a few changes under the surface. I don’t have a detailed list of these but the electronics, filament feed and bed are changed. I’ve only worked with a single material so far but the bed has very good adhesion. The software has been improved since December and is easier to understand what is going on.

    Specific Tests

    There was a few things I specifically wanted to look into to uncover the strengths of the printer but also see how I could use it for my own projects.

    Speed of printing

    The printer is quick to print and the dual nozzles helps with this. However I have discovered that speed is also dependent on the cooling speed of the plastic so you can’t always just print as fast as you want. Typical print times for the objects I’ve created are in the 1-2 hour range, objects such as my lamp housing I’m having to simplify so that the print time is reduced as I don’t really want to leave the printer running all night. It is fairly quiet but in a silent night-time house it is quite noticeable.

    Quality of finish

    The fine nozzle produces excellent prints and there was minimal need for finishing post printing. The draft prints are obviously 3D printed with a the lines of print clearly visible.

    Ease of deployment and packing up

    It’s a simple as using a regular printer in this respect with just a power cable and USB. I have been ejecting the spool at the end of each session and popping it back in the bag so that takes a few seconds more than a regular printer. I think that I did not realise I was using ABS rather than PLA until a long way through the test is a good indication that the automatic settings with the print cartridges are doing their job well.

    Thin items such as the clock hands to check for warping

    My tests on this have demonstrated that you can’t just print small items on their own. I don’t think this is a limitation of the printer but it isn’t just something you can do “out of the box”. I hope to do more tests to print small gears to work out best practice for those kinds of parts.

    Moving parts such as bearings and concentric shafts to check for accuracy and surface finish

    The phone stand had a clip together part and that worked with minimal clean up. I’ve read that you should allow 0.5mm spacing between moving parts as a generic “fit”. I will likely investigate that more in future and look at tolerances and fits for 3D printing on my own Workshopshed blog.


    The models I’ve used are listed on Thingiverse and MyMiniFactory. The ones I’ve created are at


    You can indeed print out of the box and a several of the example model’s I’ve picked work very well in that aspect. I have even managed to print one of the three challenge prints successfully on the standard settings. There are things that are trickier to 3D print and the thin gears that I wanted to check for accuracy seem to be one of those. The accuracy of parts does however seem to be dependent on the heating/cooling characteristics of the material rather than the accuracy of the printer. For example the die I printed did have some distortion and ended up not totally square. The gears also suffered badly from this.

    I do plan to use the printer for a range of other things so if you enjoyed following the blog posts then you can expect a few more in the future with a slightly different title. I also know that a few of the other Element14 members have Robox printers so we can help each other out with any issues.
