A 3D printer is a tool, not a hobby.

Thanks to clever design and smart sensors our 3D printers do not require expensive materials, special knowledge or complex setup to run. Concentrate on design and let Robox do the rest.

Robox® Plug and Print.

Get back to the real work.

Designed for designers

Robox hardware, it’s features, functions, consumables and accessories as well as the software which controls everything has all been designed to improve workflow simply by working without fuss.

By making a machine which works as expected, without the need for setup, tweaking and special skills to run we have made a tool which does what a tool should, Robox makes the process easier.

That process could be prototyping a new product, building a scale model, testing a theory or a simple jig to make holes in the right place or stop a project rolling off the desk.

3D Hubs allows thousands of printer users from all over the world to offer reviews of printers they use every day.  We won Best of Plug and Play awards 2 years running. Right on target.

Unique and powerful selection of 3D print heads.


Quickly swap heads between all your Robox machines without the need for tools.

Simple but powerful software

Software is vital in a 3D print setup. We made our own user interface and firmware so we could make the process of setting up and starting a print as easy as possible. The ease of use of AutoMaker has won us some really nice feedback from 3D printer reviewers.

On the surface you see a simple drag and drop model loading interface, choice of 3 carefully tuned default print profiles and a button which says “Make!” All you need is a model and a SmartReel.

Under the surface is a profile library which allows control over critical settings and features along with a filament library which can be copied and edited. Print and filament profiles can be shared within the Robox Community and the open material system means there are a lot of filament profiles around.

AutoMaker runs in Java which is compatible with a wide range of operating systems. We have designed and tested it for use on recent Windows, Apple and Linux  systems. Cura is used as a slicing engine but you never need to see it, everything is controlled within AutoMaker.

Software is actively maintained and updates come often, the latest can be downloaded here. If connected to the web the software checks for updates on startup. You can try AutoMaker with limited functionality without a Robox attached.


These 2 versions of Robox are built on an identical base. Every part of RoboxDual can be fitted to a regular Robox and it is possible to convert it for dual material printing without limitations. The obvious difference is the colour of the aluminium wrap around the body, next you will see the extra reel holder, this is a simple addition, the last easily visible difference is the head, RoboxDual can use any of the Robox HeadLock heads and these can be swapped without any tools. Internally; A requirement of dual extrusion is the ability to feed a 2nd material to the head, this requires a 2nd extruder which even the earliest Robox was designed to accept. All quite easy to this point. Feeding the material to where the head is connected requires some extra parts which can be tricky to fit, ask for advice if you intend to do this.

RoboxPRO uses many existing Robox parts such as heads, extruders and the main PCB. There are obvious changes such as the z drive and guide rails which have been beefed up considerably, these required larger stepper motors to move. The larger build plate uses a different heating method and will allow a range of print surfaces. Filtration of the output air via a removable HEPA filter. A touchscreen control is built in and also allows access to RoboxPro via a network interface. Where Robox was designed for the desktop, RoboxPRO has space to spare. If you need to make big parts, RoboxPRO is the best choice. If you rarely make big parts, stick to RoboxDual. Other printers copy our features but not one has done it as well as us or included everything as standard.

“The CEL Robox is a very good desktop dual-extruder 3D printer with a great user experience. The smooth combination of a beautifully designed and engineered hardware with a smart and streamlined software are the perfect example of what a consumer 3D printer should be.” – aniwaa.com

Knowledge Base

The Robox support team use a ticketing system to log service history and communicate about hardware, software and usage issues for Robox. We have gathered a lot of articles, explanations and guides describing the workings of Robox and changes over its lifetime in this support system. Keeping it there allows us to easily link that content to a users ticket and is a great resource. You can see the surface of this via this link but if you log into the support system you can view a lot more. www.cel-robox.com/support/. Please note that the login is not shared with this site, you will need an account for the support website. You can use the support site to register your warranty as well.

Material Compatibility

Just clip the reel on, setup is automatic.

Robox SmartReel system simplifies the print process by automatically setting Robox up for the reel clipped to the side of Robox. A chip on the reel is programmed with print speeds, diameter, flow rates and temperatures for nozzle, bed and build chamber at each stage of printing. This means a user with no printing experience can jump straight in and benefit from the huge range of materials Robox can print with. For an experienced user this is a great time saver and allows very easy changing of materials. RoboxDual has 2 reel readers and the ability to combine either two colours in the same layer of a print or one model material with a dedicated support material which can be easily removed after printing.

Third party materials are able to be used with Robox.

There is no manufacturer lock in or hacking required to use practically any 1.75mm filament available. We encourage experimentation by knowledgeable and experienced users and offer advice and tested print profiles via the Robox Community. By enabling the Advanced Mode you can edit the SmartReel profiles and create your own, you can save these to reels or simply feed material in directly from its original reel, just tell AutoMaker what it is via a custom print profile. The warranty terms require that you take responsibility for damage from third party filament and “filled” filaments which will abrade the surfaces are not recommended unless using the SingleX head.

Many printers claim compatibility with engineering materials. Although an open frame printer can create shapes with a common material such as ABS, in reality it needs a box over it. The ambient environment needs to be controlled or the thermal shrinkage will destroy the accuracy of the model and in many cases the print will fail before it completes, wasting time and filament.

To print in a wide range of materials the printer needs to be able to generate, monitor and maintain suitable temperatures for nozzles, bed and ambient conditions in the build area. Some printers will offer awkward (ridiculous) or expensive covers for their printer, Robox does it all as standard, automatically. Not only that, we do it far faster than any other printer, build plates heat up to higher temperatures in 3-5 mins, not 15-30 mins, many can’t even achieve the required temperatures to ensure adhesion throughout the build process.

Engineering materials such as Nylon, ABS and Polycarbonate are all excellent, strong materials for creating strong, working models. All of these and more are not just compatible with Robox but print very well.
