Out of the box dual material printing.

RoboxDual is an update to the original Robox and includes a Dual Material Head, 2 extruders and the ability to print in 2 materials at once. Updated parts and manufacturing techniques provide redundancy and future proofing.

Already got a Robox? Don’t worry, the original Robox can still be updated with many of these new parts using DIY upgrade kits or vendor provided services.

The best thing about dual material printing is the ability to create parts which were previously difficult or even impossible with a single material printer. By creating a support structure with a material which can peel away or be dissolved from the model easily we can increase the accuracy of overhangs and still remove these supports without damaging the model. A mechanical design engineer can now prototype injection mould designs on their desk without needing to modify the design for ease of printing.

Home users

Robox will soon be your favourite tool, it is easy to use due to good design. This design does not limit its potential, it leaves you as a user able to spend more time creating and less time scratching your head wondering what the printer is doing. Start your 3D print experience with a successful print, not a soldering iron.


At any level, Robox can help to demonstrate an idea, prove a theory or inspire a career. Robox will give teachers the confidence to press print and be certain of the result or even to allow students full access to the printer due to inbuilt safety features.

3D print experts

You may have tried the best of the rest, the kit printers, the well known competition of Robox, all of them are using the same technologies. Some do it well, some have good features but none of them have true innovation. Robox nozzles close, this is unique to Robox. Ooze, stringing, retracts, you know these terms, they don’t apply to Robox. Viscous materials will not leak out, dual material printing will not waste material and time doing purges, wipe towers or heating/cooling operations. Robox nozzles lift out of the way when not in use, they don’t drag across the print or get stored away to dribble in the corner.

Robox changing materials during a print: Close>Change>Open>Extrude, it happens in less time than it takes to read those 4 words.

If you are still manually levelling your bed, you need a Robox. If you wait 10 mins or more for your bed to heat and don’t get to see the first layer, you need a Robox. If your calibration procedure is mysterious and confusing with variable results, you need a Robox. If you are spending more time fiddling with settings and doing test prints than designing and using the results, you should have bought a Robox in the first place.

The materials range? Infinite ∞ because Robox will allow you to use any material you want. If you know what you are doing and are prepared to take responsibility, you can feed any 1.75mm filament into Robox.

Robox comes with a 2 year warranty on non-consumable items, not all 3D printers have such a generous warranty. Some of the most prominent brands have only 90 days, there must be a reason for this…

A robot in a box, Robox.

Robox is more than just a 3D printer, it is a micro-manufacturing platform. The precise positioning of the 3 axis system along with the mechanical and electronic design of the HeadLock system provides a robust framework on which to build a range of manipulators and scanning devices to allow this robot in a box to do much more than just create beautiful 3D prints.

Head Lock™ Tool change system

The HeadLock system is a tool-less locking system with plenty of scope for high powered and complex additions to the rigid 3 axis frame. We are developing a range of optional modules which connect to this system.

Future modules could turn Robox into an automated light machining rig, a 2D drag knife cutter or even a paste extruding system for ceramics, chocolate and a whole lot more.

Needle Valves – A patented feature unique to Robox. The needle valves help prevent stringing of low viscosity materials which experienced 3D print users will know to be a problem. This feature is used in our 3D print heads and allows Robox users to have far more control over the placement and flow of material.


Tool-less locking system

Dual Material

RBX01-DM This head is included as standard in RoboxDual packages.

2 independently controlled heater elements give high levels of control across an immense range of materials.

On this head the 2 nozzles are the same size and are fed by 2 separate material feeds. Use one nozzle for the build material and the other for easily removable support, or a material with different characteristics for a custom composite, or simply create a multi-colour print. The key purpose of this design is to allow users to create 3D objects which are difficult to print without support structures. Use a suitable material for your model and choose a dissolvable or easily removable, peel away support material. You can select sections of a model and change the material assigned to each part or arrange your 3D model in the optimum orientation and tell the software to generate automatic support using either material loaded.

Needle valves are unique to Robox and allow far faster and more efficient printing of multiple materials on the same layer.

The allowed temperature range will future proof this head for materials not even invented yet.


Tool-less locking system

Quick Fill™

RBX01-S2 This is an add on module for Robox.

Needle Valves – A patented feature unique to Robox. Increases material compatibility and reduces flaws caused by stringing. A certain stop to the flow of material rather than relying on filament retraction as in all other 3D printers.

Quick Fill™

Dual-Nozzle Technology – Although much faster than traditional prototyping methods 3D printing is not a fast process, Robox users can enable faster prints by using the large nozzle to fill unseen internal sections. Both nozzles can be used in the same print for faster print times without sacrificing detail. In this head both nozzles are fed from the same reel of material.

The large 0.8mm nozzle can quickly create a model with exceptional strength due to a large wall thickness and fast print time with large layer heights (up to 400 micron/0.4mm/400µm). The small 0.3mm nozzle for fine details and extremely low layer heights (down to 20 micron/0.02mm/20µm).

Bespoke Electronics

The rigid frame is a skeleton for some very clever and unique ideas

Many 3D printers use open source or cheaply available electronics, these certainly have their place in the world but nothing beats a product made specially to perform a specific task. Robox has a bespoke mainboard which runs an Atmel® processor and custom made firmware to control motors, monitor filament usage and temperatures and run the unique SurePrint™ tasks which make Robox work reliably and safely at all times.

The internal power supply provides power to all the electronics and has been specified to provide the fastest heatup times of any plug’n’play 3D printer. This greatly improves the printing experience and because the user is present to watch the start of the print it also reduces failure rates and wasted filament.

All this intelligence built in is not enough to create a class leading micro-manufacturing platform. A rigid 3 axis frame provides a basis for a highly accurate, low maintenance, cartesian system – This frame format is common of high end CNC machines and many other 3 axis machinery. By using this design and the HeadLock tool attachment we intend for Robox to be much more than just a 3D printer.

Parts which are critical to the success and precision of an operation have been carefully selected and if required made specifically for Robox. The Metric fine threads of our Z axis drive motors are custom made and fitted directly to stepper motors on each side of Robox, these are driven up and down on precision ground stainless steel rods to provide the best Z resolution of any 3D printer on the market. Precision components – bearing surfaces are machined to an exceptional tolerance and matched to high quality linear bearings.

A stainless steel sheet is carefully shaped to provide a rigid base for the frame and fixed to our injection moulded housing to provide a product which is easy to manufacture to enable the best quality output from our manufacturing partner. Robox has been designed to be mass manufactured, this simplifies the process which in turn improves the quality of the final product but without increasing the price for the end user. More reliable, repeatable, better quality production, not just for us but for the users of Robox as well.

Smart Extruder™ System

RBX01-X2 Filament movement monitoring

The quantity of filament used to create printed parts is critical. So important that Robox was designed to constantly check that the volume required matches that which is actually being fed to the nozzles. This design is so successful that another prominent 3D printer brand immediately added a similar function to their flagship printer.

Over 4Nm torque – The required torque for most print materials is much less than this but this headroom allows Robox to print with a much wider range of materials and reduces the chance of print failures common in many other 3D printers.

Dual feed wheels for zero filament slip – In the Robox extruders the filament is trapped between 2 contra rotating wheels which grip and push the filament toward the nozzles.

Indexing in the SmartExtruder enables automatic loading and fault detection and also measures filament used.

RoboxDual is fitted with 2 RBX01-X2 extruders

Smart Reel™ System

Plug and play materials make 3D printing easy

Robox material partnerships give users access to an excellent range of materials on the SmartReel system. We will continue to select the best materials and partner with leading material producers to complement and extend the versatility of Robox.

Polymaker offers materials specifically designed for dual material printing such as Polysupport; a material which is slightly flexible and peels away without leaving residue or artefacts commonly seen when removing support. Polysupport can be used to support a range of materials.

ColorFabb filaments are widely used due to their excellent colours and ease of printing. The nGen range of filaments holds food safety certificates which make it very popular with dentists and lab technicians making 3D printed surgical guides using Robox.

Robox users are not locked into a material system, Robox is able to use any compatible material from any manufacturer. In such a new and quickly developing world of material development it is very disappointing to see so many 3D printer manufactures limiting the creativity and inventiveness of their users.

Material partnerships let us provide the best, most useful and most popular materials on our SmartReels. Companies like colorfabb have amazing materials so instead of competing with them we partnered to provide our users with the best materials on the simplest reel system.

Each Robox filament SmartReel is fitted with a rewriteable EEPROM microchip to store material data and enable automatic recognition of a wide and growing range of materials we supply including PLA, ABS and HIPS in a choice of exciting colours. With this system, we already support the widest variety of materials on the market.

Thermo Surface™

Build Plate and Heated Bed

Robox bed heats to maximum temperature much faster than any other 3D printer


minute heat-up time

Heated bed – Vital for printing in certain materials, Robox bed heat up time to 130°C is under 3 mins, less than half that of any of our competitors. Compare bed heatup time with other printers, it is common to wait 20 mins, many take even longer. Removable 2 sided print surface – Almost no maintenance required, occasional cleaning of the flexible surface with alcohol at the most. Other 3D printers require disposable surfaces like masking tape or even hairspray.

Thermo Surface™

Unique to Robox, 1mm thick and easily the best print surface for use with a heated or cold bed and most of the materials used in 3D printing today. ThermoSurface does not change size within the printers temperature range, when the part cools it shrinks and just pops off. No effort required, no risk of damage to the surface or the printed part.

SafeLock™ Enclosure

The only 3D printer with a temperature controlled safety lock

Enclosed build chamber for a controlled environment and reduced shrinkage – A 3D printer without a case will never achieve the same accuracy in such a wide range of materials as Robox.

User safety – The door locks while the internal surface have dangerous temperatures, this prevents accidental burns and injury from moving parts.

Desktop micro-manufacturing – Although 3D printers are normally operated in a workshop environment, Robox has been designed so every desk can accommodate it, it looks great too! The external dimensions (370 x 340 x 240mm 14.5 x 13.4 x 9.4″) have a generous build area (210x150x100mm) – Although not as big as some, the studies we have done put over 90% of 3D printed parts well within these limits, even if you do need something bigger, the print time of large parts is prohibitive so splitting the part into smaller, easier to print sections is often wise.

Advanced simplicity

Automated setup, printing and fault resolution. It’s all in the detail.

The simplicity of using Robox is deceiving, there are a lot of things going on every time you use a feature of Robox.

To load filament you just poke it in a hole but without any other interaction Robox will detect the type of filament installed and carefully load it, ready for printing. Data on what is loaded is presented to the user within the software and ready for the next step.
