Think outside the Robox

The Robox 3D printer and micro-manufacturing platform

Think outside the Robox

The Robox is more than just a 3D printer. Designed to be the simplest, most reliable and comprehensive 3D printing platform available, the Robox features intuitive software and automated hardware to get you up and running right away. The Robox has also been future-proofed to take advantage of new manufacturing processes as they're developed.

“Robox proves 3D printing doesn't have to be a dark art.”

Frame and Case Design

Frame and Case Design

The quality of 3D printing is predominantly dependent on the resolution and accuracy of the motion axes. The printer must be capable of laying down accurate slices of plastic material layer after layer to produce a usable part. The Robox has been designed from scratch, ensuring the frame and motion systems are extremely rigid and accurately positioned.

All motors and axes are attached to a single stainless steel frame, which is a reference surface for all motion. The frame is rigidly attached to injection-molded parts that form the body of the 3D printer, creating an especially stable platform for accurate high-resolution prints.

Automatic build platform leveling

Automatic build platform leveling

One of the major problems with almost all 3D printers is that the printer bed must be manually leveled to ensure the first layer adheres correctly. This is a finicky process that has to be regularly repeated, making it a source of endless frustration for too many 3D printer owners. Well, the Robox designers have solved that problem. Robox uses a proprietary bed-probing mechanism to measure the location of the bed before every print. Since both Z motors are driven independently, they can be adjusted to ensure the X axis is always parallel to the print bed.

Printer Construction

Printer Construction

All of the motion axes are coupled to a single sheet metal part, reducing the need for factory calibration and ensuring that your Robox is perfect for printing straight off the production line. The use of injection-molded parts combined with sheet metal components produces a very rigid structure, while allowing for a stylish consumer product.

Minimal Inertia

Minimal Inertia

By using a Bowden tube extruder, the weight of the printing head is kept to a minimum, allowing for much faster extrusion and travel speeds without affecting print quality. In addition, the Robox printer extruder features a dual-pinch-wheel extrusion system that provides consistent, reliable operation with complete control and remarkable resolution.

High-torque stepper motors with high-resolution axes

High-torque stepper motors with high-resolution axes

The Robox designers have over-specified the stepper motors for all the motion axes, so that the Robox can cope with all future head developments without a hitch. The Robox uses 2mm pitch belt drives for the X and Y axes and a custom-machined 0.5mm pitch Z axis screw. All of the motors are designed specifically for the printer, resulting in the highest theoretical accuracy on the market — as well as super-fine layer height.

Separate build chamber and electronics enclosure

Because of its heated build platform, the Robox can maintain approximately 50°C ambient temperature in the build chamber. This stable environment helps to maintain part accuracy and print quality by preventing uneven cooling. The only downside to having a heated build platform is that the ambient temperature can be too hot for the motors and electronics controlling the printer — so these are all housed outside the build chamber and actively cooled by outside airflow to keep everything running smoothly.

AutoMaker Software

AutoMaker is the software used to layout your models, view the status of Robox, and adjust the settings used during printing. AutoMaker is available to download and can be installed in most languages on many operating systems including Windows, Mac OS X, and Linux. Connect a Robox to print in draft, normal, fine, or custom in 3 simple steps. Opening the advanced tray enables a huge array of settings, each of which is clearly described and organized.

Save and share

Save and share

Save custom settings if you want to repeat a print or share it with other users. AutoMaker is designed to make 3D printing easier — spend more time designing parts to print rather than fussing with print settings. The default settings are tried and tested and enable anyone to get consistent and repeatable results every time. Advanced users have all the control required to satisfy even the most complex print jobs, and they are easily able to share their custom profiles with all of us.

Extruder construction and feedback loop

Extruder construction and feedback loop

The Robox extruder contains the world's first dual-pinch-wheel extrusion system. This allows for very consistent and reliable extruder operation as well as excellent resolution and control. The filament is fed to the printer head by two indexed contra-rotating feed wheels, which are powered by a worm-and-wheel gearbox. This arrangement virtually eliminates any possibility of stripping your filament, causing a loss of extrusion and poor print quality.

Pause and resume

Pause and resume

The filament extruder incorporates a closed-loop feedback system for monitoring the motion of filament as it enters the extruder, giving it the ability to instantly recognize extrusion issues. The software can pause the print if any error is found, allowing the user or firmware to rectify the problem without ruining the entire print. A long-awaited feature on 3D printers is resume — the user can restart the print and it will continue from where it left off.

Nozzle valve system

Another problem typical of 3D printers is ooze: the stringing and over-extrusion at the end of a section of printing. Most 3D printers compensate for ooze using a retract, but this technique is not always effective. Robox has solved this problem by using a needle-valve system that completely closes the nozzles at the point of extrusion, removing all stringing and blobs from the part, resulting in an amazing surface finish. Robox is also able to use a much wider range of materials than any other 3D printer.

SmartReel filament

Robox materials are supplied on a SmartReel that holds data about temperature settings, print speed, diameter, and even the amount of filament used on that reel. SmartReel filament makes printing very easy — simply load the filament and AutoMaker will automatically change to the settings saved on the reel. Robox currently allows you to print in PLA, ABS, HIPS, Nylon, PC, and PVA. The Robox designers are constantly testing additional materials, too.

Filament simplified

Each release of AutoMaker includes the latest profiles for each type of filament, and these are automatically updated when an unmodified Robox SmartReel is loaded. Anyone can share filament profiles created for various materials, even if they aren't supplied on a SmartReel. Robox can use filament from any brand — you don't have to use the SmartReel system if you don't want to.

Using your SmartReels

Using your SmartReels

If you want to use another 1.75mm diameter filament, just feed it in and tell Robox to get the filament data from a file rather than reading the SmartReel. You can download this file or create your own by copying the default Robox profiles, and then editing them within AutoMaker or via a text editor. You can also write your saved data to a SmartReel at any time.
