Scara Elite V2

The Scara Elite v2 is our refined viable large-scale ceramic 3D printer. The Elite prints with clay or cement and has a much larger build volume than the Scara v4. The advanced design and substantial construction can handle onboard loads like the 3D Potter 4000ml clay extruder or a hose assembly. Where the v2 really shines is when it's coupled with a large capacity continuous high-pressure hose extrusion system which can deliver clay loads between 85 - 250 lbs of continuous extrusion.

Speed and noise

The Scara Elite v2 is capable of extreme speeds however speed is relative when it comes to ceramic 3D printing. Realistically you won’t want to exceed 130 mm/s. Many factors determine the speed like nozzle size, layer height, and achieving a good adhesion on the interlayer of the clay. Even with a fast printing speed the printer maintains low noise, which allows operation 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 printer is crafted 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 are a brand very sophisticated hybrid closed-loop stepper motors. These have onboard 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 many large manufacturing facilities. These drives are extremely heavy-duty and capable of precision movement down to 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 advantage of this machine is that when it is mounted on a sturdy tabletop you can start printing right away within a limited envelope area. Or you can give it its own dedicated space for a partial or full envelope. The space needed is determined by the end-user and how much of the print envelope they choose to use. Whether on the tabletop or the floor, the Scara Elite will require direct mounting for maximum stability. This is achieved with multiple screws to secure the printer to the surface it is mounted on. If you choose to use a tabletop it must be of substantial construction, the minimum is 1.5" thick heavy plywood or wood construction. Not securing the printer appropriately will result in the printers diminished performance depending on the build envelope and speed at which the prints are created.
