Press Release: Launch of an ambitious new UK joint venture challenging established manufacturing methods

5th June 2018

For Immediate Release

Two innovative UK manufacturing companies are excited to announce that they are setting up a Joint Venture called Q5D Technology to launch a disruptive new technology that could change the way products from white goods to cars and aircraft are manufactured. Most of the products that we use today are built by machine, but one part eludes automation: the wiring. This is still done by hand, in distant factories, where nimble fingered workers create wiring looms on peg boards. These are then shipped and fitted, again by hand, into the car or other product. It is expensive, inflexible and time consuming.

CEL-UK Limited is an engineering firm based in Portishead near Bristol. It is expert at the design of equipment for mass manufacture. They make and sell highly regarded 3D printers under the Robox® brand. Chris Elsworthy the Managing Director explains “By combining existing technologies we are making a new breed of machine that is able to create polymer parts with embedded wiring and electronics of any shape that can an assembled autonomously as part of the manufacturing process”.

M-Solv limited is an Oxfordshire based high-technology company which makes machine tools for the rapidly growing printed electronics market. “This new technology will be able to make lighter, cheaper, more complex components that will enable engineers to go from concept to product much more quickly” explains Phil Rumsby the Managing Director of M-Solv.

Stephen Bennington of Krino Partners Limited “These two companies each have unique technology as well as the depth of experience and access to the markets that will ensure that this new venture will be a success”.

DEVELOP3D Cover Story April 2018 – How CEL took the next step to address the professional 3D printing market

By | News | No Comments

RoboxPRO is on the cover of Develop3D April 2018 magazine!

On the 4 page spread inside you will learn about the CEL development of Robox and how we are proud to see that so many of our early innovations have been so widely duplicated in competitors to improve the ease of 3D printing for everyone. In a market where so many machines shown no innovation at all over the past 5 years, Robox has lead the way in terms of new features. Such as dual material printing and material control, adaptive bed levelling and automated setup, filament delivery sensing and error response, reel recognition and simplified user interface.

Read the article to find out why CEL made a 3D printer and the key design intent for the development process and how we used our manufacturing experience to offer a machine with such advanced features at such a low price.

Find the April 2018 edition here, free if you are registered from the UK.

You can also read the web article here

The big change with this machine is that it is manufactured not in the Far East, but in CEL’s Portishead factory near Bristol.

SingleX™ – Robox development and experimentation head.

By | HeadLock, Materials, News | 6 Comments

Material development is constantly expanding upon and often stretching the capabilities of 3D printers. Robox features an open material system which gives users the choice of using filament from any source.

We have always advised against using “filled materials” mainly due to the abrasive nature of these materials. We maintain this advice with all of the heads available to fit the HeadLock™ system.

This SingleX™ head is an exception, this head is designed for experimentation. To combat wear this head comes with the very well known Olsson Ruby Nozzle with 0.6mm aperture. The SingleX™ heater block has a M6x1mm thread.

We have removed the needle valve in the SingleX™ head, so if you want to send gcode from another slicing engine you are free to do so. Dribble and ooze are now your responsibility 😀 as is any harm caused by code produced outside of the typical AutoMaker environment. This head provides freedom to use the Robox platform in new ways.

Remaining in place are many of the features which Robox pioneered in 3D printing. Surface mapped bed levelling, SmartReel material recognition and simple 3 click operation. The extruder provides feedback during a print to ensure material is not jamming or has run out, pause and resume at will.

A word of warning…When using abrasive materials, abrasion is not limited to the nozzle. Our testing has shown little wear on filament drive gears and other parts within the filament path after over 3kg of Carbon and Glass filled Nylon, ABS, PETG and other  filled filaments but these parts are still considered to be consumable.

The Olsson Ruby
Six reasons to get the Olsson Ruby

One nozzle

The Olsson Ruby will work with a huge range of materials.
PLA, ABS, CPE/PET, Nylon, and composites with abrasive additives such as Carbon fibre, Steel, Wood, Boron Carbide, Tungsten and Phosphorescent pigment, are some of the materials sucessfully tested so far.

Highly wear resistant

The ruby mounted at the tip makes sure that even the toughest materials will be printable. It was originally designed for printing with Boron Carbide (B4C), the third hardest known material in the world.

Excellent heat conductivity

Since most of the Olsson Ruby is made from brass, with its excellent heat conductivity, performance and throughput is first-class.

Verified performance

People all over the world have been testing different iterations of the ruby nozzle since early 2016. We are very happy to have received only good printing results from this community.


By using the 0.6, 0.8mm and High Output versions it is possible to reach a higher throughput and speed than ever before for abrasive materials, while retaining wear-resistance and reliability.

Manufacturing quality

The Olsson Ruby is manufactured, assembled and tested in a high-quality facility in Sweden. This is why 3DVerkstan guarantees the very best quality and tolerances.

Wear resistance compared

Brass, 0.3kg carbon fiber filled filament printed.
Stainless steel, 1kg carbon fiber filled filament printed.
Hardened steel, 4kg carbon fiber filled filament printed.

Robox is a tool, not a hobby.

By | Design, Education, News | No Comments

Robox is designed to be Plug and Print. We are designers, we created Robox to allow us to spend more time designing, testing and refining our prototypes. Doing our jobs basically. As designers we did not want to spend time levelling or preparing a build plate, looking up or testing settings or tweaking profiles. We wanted a 3D printer which makes printing easy. Robox has won best of Plug’n’Print 2 years running. It is also the only printer which is safe for use in education at all levels.

3D printer software development

By | Jobs board | No Comments

CEL produces Robox which is a class leading 3D printer with global reach based in Portishead near Bristol, UK.

Our success and innovation in the additive manufacturing (AM) field has led to funding for new developments in similar technologies. There are two stages to this which follow very similar paths and promise several years of very rewarding work which will become a very high value product. This development will further expand the use of additive manufacturing in industry by enabling automation and streamlining of currently impossible tasks or tasks which are cost prohibitive using available methods.

CEL-UK have an opportunity for a creative software developer to join our team of mechanical engineers and firmware specialists to develop the next generation of AM here in the UK leading to intellectual property and new machinery which will be sold around the world. The role/s could be filled by a person who can plan and lead a project, growing a team around themselves and/or someone who can do the leg work and work to a plan which is defined for them.

The role of software in this project is vital and, as this is a new project, is completely open to the creativity and ingenuity of a capable developer to shape into a valuable manufacturing tool.

The new projects have links to our existing work but will require a higher level of control and processing of three dimensional models into code to control machinery. G-Code has been used in CNC machining and robotics for a long time and is almost identical to that commonly used by most 3D printers.

The software application created during this project will have the ability to import one or more digital 3D models. Rules will be applied which generate toolpaths based on these 3D shapes for use by embedded firmware and electronics which will be developed alongside the software. Hardware such as stepper motors and valves will be controlled via the electronics. The resulting movements will produce physical objects with the features and dimensions of the original digital model.

There are existing tools and applications which can produce machine code close to what we need. It is possible that the final application will be combination or rework of existing code or a totally new application written from the ground up.

C++, Java, other… The programming language used will be that which best suits the planned project and the team.

The final application will include a user interface and is likely to receive regular or live status reports from the firmware. This interface may be independent or possibly built into an existing application as a plugin or extension. To satisfy the initial brief this interface can be very basic.

Initial features of the software will allow the user to alter settings which tune the output of the machine to ensure the best possible quality and reliable, repeatable results. Building on this we intend to add features which focus on user experience and production efficiency.

There is significant separation from our existing software, AutoMaker, but the projects may converge as development progresses and there is likely to be some crossover which benefits both of these projects. AutoMaker is a user interface for the commercial 3D printer hardware which is Robox. It allows a user to monitor Robox hardware and to lay out a print job and choose settings, these are sent to an open source slicing engine called Cura and then the resulting code is altered before being sent to the Robox hardware where it is stored and accessed by efficient and bespoke firmware and electronics. AutoMaker was developed using JDK 1.8 and JavaFX along with typical development tools, Git, Jenkins, Jira and Netbeans IDE.

The perfect person for this position could be either; someone with experience in leading a project or; someone who can do the leg work and work independently to a plan which is defined for them. Most importantly this person will be excited and passionate about the project.

This person/team will probably have:

  • An excellent mathematical understanding of three dimensional spaces. Computational geometry.
  • The ability to plan and prioritise to ensure realistic goals are met and features are completed.
  • Strong communication skills to work with the team and achieve the best outcomes.
  • Excellent project management to ensure resources and code are efficient and easy to maintain.
  • Strong debugging and test abilities.

Relevant experience will include:

  • Application development from start to finish. Systems to UI.
  • Manipulation of 3D spaces and models and rendering, generation, control or processing of this type of data.
  • Robotics, Machine code, 3D printing or CNC control.
  • Project planning including user experience planning and improvement.
  • Integration of software and hardware functions.

CEL is a friendly and casual workplace with a great team of talented and inventive people. Our core business is product design so there are always exciting technology projects running. We are about to expand into a very new and exciting venture and we would love the right person to be part of it and grow with us.

Full time, Salary negotiable.
