Opening the post has never been so exciting for us as it has been this past month. The very first Robox Print Competition, open to BETA backers only, has been a roaring success, so much so that we have decided to run a monthly competition as the Robox gradually gets rolled out to more and more people.

September’s competition was a real test for us, as it was the first time we could witness prints made by people who didn’t work for CEL, and didn’t know the Robox inside out.

We were relying on our BETA testers to get to grips with the first Robox units which rolled off the production line, to produce as high quality prints as possible. Tellingly, the first round of Kickstarter backers rose to the challenge, with some people entering several prints rather than just one.

And so… the winner is…. drum roll please…. DAVID MUSSAFFI!

David entered several models into the competition, but it was the Woman’s Torso Sculpture which really impressed us, and which has been selected as the overall winning entry.

And to watch the Robox creating the Woman’s Torso have a look at the You Tube video:

David will receive a filament pack as his prize, and we can’t wait to see what he enters into October’s competition!

However, David’s entry wasn’t the only one to impress us, so we have decided to create a runner up position, and this will be awarded to ROB HARWOOD for his beautiful Scripted Vase.

Rob will also receive a little goodie pack for his troubles, and we hope to see more entries from him in future competitions.

Thank you to all BETA testers who took the time to print and enter our very first completion – some of these entries will be on display at the TCT Show at Birmingham NEC between 30th September and 2nd October, so come and visit us on stand B40 to take a look.

And watch this space for news and details of our next competition, which will be launched on 1st October 2014.

This is the news everyone has been waiting for… the final batch of Kickstarter units are now on their way to our very patient and loyal backers.

We can confirm that all units are currently being air freighted worldwide from Hong Kong as we speak, which means backers will start receiving their units over the next two weeks.

Shipping times will differ depending on where backers live, but on writing this post we’ve already been made aware of a happy backer in Australia opening their door to a Robox unit this morning.

All we would ask is that if you are expecting your unit, please be extra vigilant looking out for couriers, or delivery notes – we wouldn’t want a Robox to go unaccounted for at this final stage.

We can’t wait for our backers to receive the very first units from the production line – all dressed in limited edition Kickstarter colours and supplied with two taster reels of filament.


Don’t forget this might be the end of the Kickstarter campaign, but it’s only the beginning where the Robox is concerned.  The hardware has reached a point where we’re happy with the build quality and print quality, but there will be constant updates with software which everyone will benefit from automatically.

Please do sign up to the Robox forum as when you are in receipt of your unit we would welcome your feedback and shared print and material profiles.  You can join our community via this link

At times you may also need help using the Robox, so please visit our support portal where we will try to help you with all technical enquiries as quickly as we can

And please continue following both the blog and forum, as we’ll soon be posting details of a new print competition in which ALL Kickstarter backers can participate.

Finally, a massive THANK YOU for sticking with us, and being so patient.  As we’ve tried to communicate, this is a brand new project and so there were bound to be teething problems along the way.  Any delays have been because we’ve tried to ensure you receive units which are as near to perfect as possible.

We hope you enjoy using the Robox, and please do remember all helpful feedback will benefit us all going forwards.

Print Quality

By | News | 4 Comments

One of the primary concerns for any 3D printing company is being able to produce good quality prints, as ultimately everyone will judge the success of a new printer on the market by the condition of its prints.

With this in mind, we wanted to demonstrate the capabilities of the Robox as it currently stands, as our units are able to produce three different quality prints, in different time frames and using different methods.

The quickest way of producing a print is to select the ‘draft’ quality option; this produces the design with layers 0.4mm high, using just the 0.8mm nozzle. To put this into perspective, the orange robot in the picture has been produced as a ‘draft’, and took 1 hour and 27 minutes to produce.

We selected a 20% fill, which means the inside is only 20% solid.

So the downside of printing something as a ‘draft’ is that the quality isn’t the best – but with a bit of finishing you can polish these models to look better. The upside is that you get to see your print in a really short space of time – great for those of us who are impatient and like immediate results!


The second fastest way of producing a print is to select the ‘normal’ quality option; the difference here is that layer height has been reduced to 0.2mm. For ‘normal’ prints BOTH nozzles are used – the 0.3mm nozzle produces the outer layers, and the 0.8mm nozzle prints the 20% fill. The white robot has been printed with the ‘normal’ option selected, and took 2 hours and 18 minutes to make.

Immediately the change in quality is noticeable; the layers are much less visible and the overall detail is higher. And the print still didn’t take very long to produce, once you’ve pressed go there’s just enough time to make and eat your evening meal before seeing what has emerged on the build platform.


Finally, the third option you can select on the Robox is the ‘fine’ option; which allows you to produce excellent quality prints with layers just 0.1mm high, using only the 0.3mm nozzle.

The yellow robot in the picture demonstrates just how brilliant prints are when users select the ‘fine’ option. This robot took 7 hours and 18 minutes to print – which was no problem, as we set it to print at bedtime and woke the next morning to a model where the layers are barely visible, and the surface of which is smooth and virtually perfect. We are working on print profiles that have this level of detail but utilize the dual nozzle system to further reduce print time, all these options are available for advanced users, only on a Robox is this possible.


With even more time to spare, the Robox is able to print with layers down to 0.02mm, but at this layer height you can imagine you’re tying up the printer for a long time.

As far as we are aware, there is currently no other printers on the market right now which can perform the same range of print qualities – most either have a large nozzle for fast printing, or a fine nozzle for high resolution printing, or a compromise somewhere in-between. We’re really excited to be offering a printer which is unique, and which users can play with at their free will.

And this is just the start for us, in the future differing print qualities will be a small part of what we can offer with the Robox. We’re already planning a multitude of interchangeable heads which means the Robox is both an investment AND the future.

We are delighted that independent specialist retailer of desktop 3D printers and 3D scanners CREAT3D have chosen to exhibit their trade sample of the Robox at this week’s 3D Print Show in London.

CREAT3D will soon be adding the Robox to their product line-up, and following the show will display the unit in their showroom in Reading. Units will also be available for pre-order direct from

Simon Chandler, Managing Director of CREAT3D said: “CREAT3D are keen to work with innovative and exciting British designers and manufacturers and so we are thrilled to be able to offer our customers the Robox 3D printer from CEL.

“The Robox has many unique features and offers many of our customers an accessible way into 3D printing with a highly capable product at a very competitive price.”

For us at CEL, we couldn’t be happier to have the backing of a company such as CREAT3D, as they’re a like-minded company and we believe experts hand-pick the best of the industry to display and sell on their website.

To find out more about CREAT3D, and see the Robox in action, visit stand P15 between 4th and 6th September at Old Billingsgate.

During what has been the busiest time in the history of CEL-UK, we are excited to say we have moved our entire UK office and warehouse this week.

It is a ridiculously crazy time to decide to move, as we’re in the middle of trying to perfect the Robox ready for worldwide launch, and most importantly fulfil the orders of both our patient Kickstarter backers and our loyal customers.

But in order to meet these demands, and ensure that the Robox has a future we desperately needed offices big enough to accommodate our growing workforce and a warehouse large enough to house the next shipment of Robox units.

So as of Monday 1st September our official trading address will be as follows:

C Enterprise (UK) Limited
Unit 3
Harbour Road Trading Estate
BS20 7AY

Our telephone number will remain the same +44 08453 88 97 69

All in all an exciting time for us all here at CEL-UK, so watch this space for more job adverts and news of further developments!

Spit, Polish and Elbow Grease

We are moving forward on production now and the teams’ focus is moving from mechanical improvement to software features and all the systems we need in place before the general public can buy, register and use their Robox.  For long time we’ve tried to blinker ourselves and only work towards a stable mechanical and electronic platform to set a good foundation for the Robox system, but we are now in a position to start looking at the new features, and print quality improvements.

Chris White has been beavering away at the user manual, safety information guide, quick start guide and warranty registration. The links on this download page will go live soon.

Any surface to the bed in just 2 clicks!

Tony has been working on a feature we are all very excited about; the ability to place any face of the model down on the bed with only two clicks. We have had a version of this working before in the office but Tony’s eye for detail has ironed out most of the final bugs and we hope to include this on the next release of AutoMaker.

Chris E and Ian have been focused on improving print quality and are experimenting with and implementing new ways of closing the needle valves without leaving imperfections on the surface of the printed model. We say Chris E has been working, but he’s mostly been playing with Ian’s new code then telling Ian what is wrong and what is right, Ian’s been doing most of the work!  But the good news is we’ve found and removed a few bugs in the process and are starting to dramatically improve print quality. These software changes will be passed internally to our test guys so we can bullet proof them and generate the new print profiles to take full advantage.

Peter is busy still in the forums and support portal talking to our BETA team, helping them where needed and gathering all the user information that’s feeding back into the development of Robox.
My Mini Factory

IMakr are interested in stocking our product and we’ve had a few interesting discussions, but one of the cool things that’s come out of these conversations is the idea that we will integrate their online model parts library MyMiniFactory with AutoMaker. All the models on this site are tested and confirmed to be 3D printable!

The MOST common question we get asked by people who haven’t yet considered 3D Printing to be part of their future is:

“All very nice, but what would I print?”

Well we can easily answer that now, with a library of interesting and useful parts at their finger tips everyone can more easily see how this new technology will be part of the future.

A leading high street retail group has also started talks with us and we are planning to get a Robox demo into their key stores. One day we envisage Robox being sold in place of all those 2D printers, doing all the jobs they did and so much more. This retail group are fighting the fact that a lot of us go online to buy our tech so to draw people back to their stores they are introducing a selection of bleeding edge tech to demo to the public. This fits perfectly with Robox as 3D printing is an amazing process to watch, and no one displays the process better than we do.

Selling Robox to business users will be much easier than the large but very new retail market for 3D printers. There are a few very large industry supply groups servicing the UK and Europe, we have a very exciting contract in place with probably THE BIGGEST of all. Schools, design offices spare parts suppliers, table-top gaming shops and any business which deals with physical objects anywhere between idea and reality will want one of our printers and we are well on the way to having easy and familiar channels to get Robox where it is needed.

Where is my machine?!

By | Kickstarter, Prototype Build | 2 Comments

Quite understandably we receive many enquiries every day of the following nature:

  • I pre-ordered my Robox back in March, but where is it?
  • I’m a backer on Kickstarter, but haven’t yet received my machine?
  • I would like to order a Robox, can you tell me when it would arrive if I do?
  • We are interested in becoming a reseller / distributor for the Robox, when will a sample become available?
  • We are journalists and we’d like to review the Robox, when can we have a unit?

And so on…

Enquiries of this nature both excite us, and terrify us at the same time.  Why?  Because it is very hard to give definitive answers and expectations are so high, and it’s so fantastic having people so keen to get their hands on the final product.

What we can say for sure is that our first level of Kickstarter supporters now have their BETA machines and their feedback has been somewhat amazing.  Not necessarily because all of the comments have been positive, but because even the ‘constructive criticism’ has helped us to make further developments with the machines.

So what can we tell all the other people who are waiting so patiently?

Well, Chris Elsworthy, the brains behind the operation, has just landed back in the UK after an eventful and productive trip to China.  The aim of this recent visit was to iron out all remaining niggles to ensure that when he gives the nod to mass production, the whole team are confident about the products we are sending out.

The Robox units are currently undergoing essential emissions testing – to make sure they cannot cause interference with other electrical or electronic equipment and communication networks.  The good news is that the units passed the initial tests once a few tweaks were performed by our electronics expert Mr Sing and we’re hopeful the final tests will be performed and passed later on this week.

Much of the time Chris was in China the team were performing electrical safety tests such as continuity testing, high potential testing, double insulation testing, drop testing, life testing and so on. Currently we have several machines which have been running for over 400 hours, without any major faults!

And once all of these tests have been completed and passed we can finally let all our patient supporters have their products.

So let’s talk DATES…

Until this point, we’ve not wanted to promise dates as things are always changing, and with any new products there can be unforeseen problems which lead to delays.

But we’re finally confident that we can start talking about realistic delivery dates, and we’re hopeful that the next two stages of Kickstarter backers will be in receipt of their goods by the middle of August, and our valuable customers who have placed pre-orders will be opening up their brand new Robox units early September.

So things are getting exciting now; not only are we just about to unleash the Robox on the world, we’re also moving to bigger offices soon to accommodate our growing team, and we’ll shortly be advertising for more staff – so watch this space!!
