Researchers from the University of West England’s Centre for Fine Print Research (CFPR), located in Bristol, UK, are working with a six-axis Mitsubishi Electric MELFA RV-Series articulated arm industrial robot to create a novel form of expressive 3D printing.
With its use of complex geometrical shapes, additive manufacturing has the ability to produce unique objects not easily made through traditional methods. Researchers at CFPR aims to further unlock the artistic capabilities of 3D printing by controlling extruder movements on a customized printing system.
“Conventionally 3D Printers are machines with three linear axis (XYZ) and fabrication occurs in fixed horizontal layers,” said Dr. Paul O’Dowd, Research Fellow at the CFPR.
A new 3D printing aesthetic
In 2015, Dr. O’Dowd, who specializes in creative electronics and engineering, began investigating the relationship between robotics and artforms.
“What I’m interested in is how robots can interact with the world, perceive the world, and make their own intelligent decisions and I think art, in particular, is interesting as it contains a lot of nuances.”
Recognizing the increased demand for high-quality 3D printing technologies, O’Dowd and colleagues from the UWE have connected an articulated arm industrial robot to a print generation system with the intentions of establishing a new aesthetic that surpasses the rigidity of the automated workflow of 3D printing.
According to the CFPR researchers, the main challenge of 3D printing stems from the controlled digital processes of fabrication; when an object is fabricated the shape must be broken down into a series of machine tool paths that gather material by building up layers.
As 3D printing is generally precise in terms of movement and the deposition of materials, it has been able to produce a wide range of previously unattainable structures which have been later used within industrial applications, such as construction. For example, previously, Overtec,3D printed individual complex layered components to be installed on buildings and shop floors.
