Scara Elite Roadrunner The Scara Elite Roadrunner is our next-generation large-scale cement 3D printer. The ideal 3D printer for building houses. The Scara Elite Roadrunner has a much larger build volume than the Scara v4 and expands on the Elite V2's build area with the Roadrunner track system. Where the Roadrunner really shines is when it's coupled with a large-capacity continuous high-pressure hose extrusion system, which can deliver cement loads between 85 - 250 lbs of continuous extrusion. Speed and Noise The Scara Elite Roadrunner is capable of extreme speeds; however, speed is relative when it comes to cementitious 3D printing. Realistically, you won’t want to exceed 150 mm/s. Many factors determine the speed, like nozzle size, layer height, and achieving good adhesion on the interlayer of material. Even with a high print speed, this machine maintains low noise, allowing operation in any area without disturbing the surrounding environment. Construction and Design The Scara Elite Roadrunner is capable of achieving high precision and accuracy through diligent design and robust construction techniques. The majority of this printer is crafted out of heavy industrial-grade cast aluminum, utilizing CNC-manufactured components for maximum strength, accuracy, 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 Clearpath closed-loop servo motors (Not Stepper Motors). These have onboard computers with telemetry that continually update their position for zero error positioning. In addition to high-powered servo motors, the Scara Elite Roadrunner utilizes 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 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. User interface (WiFi) Duet Web Control is a fully developed UI for the Scara. Opened in a web browser, it can be used on your laptop, tablet, phone, or other WiFi-capable device. Once a print is started, it shows information about the model being printed. Layer times, estimated time remaining, file information, and more are available for viewing. It also allows for print and extrusion speed control to be adjusted in real time.
