Potterbot XLS-1

Our latest leap forward in technology resulted in large scale robot for 3D ceramic and paste printing. 3D printing innovators, 3D Potter and Emerging Objects (www.emergingobjects.com), have joined forces to introduce a new innovation in robotic ceramic / paste extrusion additive manufacturing technology.

The new Potterbot XLS-1 is the first viable large-scale ceramic 3D printer using real clay. The advanced design and substantial construction can handle on board loads like the 3D Potter 3600 ml clay extruder or a hose assembly.


But where it really shines is when it's coupled with our new large capacity continuous high pressure hose extrusion system. We can now deliver clay loads between 85 - 250 lb continuous extrusion. Another option is our large-scale peristaltic pump that can handle non-stop continuous extrusions with nozzle sizes up to 1 inch.

Software requirements


Potterbot XLS-1 is similar to the rest of the 3D Potter line ceramic printers. It's similar to any other 3D printer which requires an STL file to be sliced by a third-party program. We recommend Simplify3D and then loaded on an SD card or USB cable connected directly to a computer. The SD card is loaded into the touchscreen where you have full control once the print starts. This gives you the ability to slow down the overall speed of the printing process and control the flow rate at any time.

Build envelope

The build envelope diagrams represent the 57 in Z height. We can do custom Z heights up to 9 feet and diameters up to 8.5 feet. 

Potterbot XLS-1 build envelope is quite unique because it's capable of printing 365 degrees continuous with continuous rotation. This means you can create a huge vessel with the printer initially residing inside the vessel or structure. This opens up a whole another opportunity to print small habitat structures (houses). Larger printers are available for this potential habitat project.

Another unique ability is printing multiple objects within the specified envelope in a sequential mode. For instance you could print a particular vessel starting on the far left side and continue to print these vessels until there is no more space left.

Speed and noise

Potterbot XLS-1 is capable of extreme speeds however speed is relative when it comes to ceramic 3D printing. Realistically you probably don't want to exceed 130 mm/s. There are many factors which determine the speed like nozzle size, layer height, and achieving a good adhesion on interlayer of the clay.

Potterbot XLS-1is extremely quiet, so it can be operated in any area without disturbing the surrounding environment.

Construction and design

We were able to achieve high precision and accuracy with this large Scara arm robot only through diligent design and robust construction techniques. The majority of this structure is out of heavy aircraft grade 6061 aluminum utilizing CNC and welded components for maximum strength and rigidity. The main rail components are from IGUS** which is one of the leading German manufacturers of precision guide rails. The drive motors consist of very sophisticated hybrid closed-loop stepper motors. These have on-board computers with telemetry that continually update their position for zero error positioning.


Drive mechanisms

This is no souped-up 3D printer, this is a dedicated heavy duty purpose-built robot. The main drives are sophisticated harmonic drive units***. These are the same drives used on large industrial robots similar to the ones that are now in most of the large manufacturing facilities. These drives are extremely heavy duty and capable of precision movement down into the fractions of a second of a degree. This means very precise prints with no backlash or jittery movements at realistic speeds. These drives are designed for maximum rigidity with extreme accuracy.

Space needed for setup

The real advantage is this machine can be positioned on a substantial table top and you can start printing right away within a limited envelope area. Or you can give it its own dedicated space for partial or full envelope.
The space needed is really determined by the end-user and how much of the print envelope they choose to use. Whether on the table top or on the floor, the Potterbot XLS-1will require direct mounting for maximum stability. This is achieved with multiple cam over latches secured to the table top or to the floor. If you choose to use a tabletop it must be of substantial construction, the minimum is 1.5" thick heavy plywood or wood construction. If a inadequate table is used, the results from the printer will be diminished depending on the build envelope and speed at which the prints are created with.
