Synchronised 3D Printing Of Concrete

- Oct 08, 2018-

Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed a technology where two robots can work in unison to 3D-print a concrete structure.This method of parallel 3d printing, known as group printing, paves the way for mobile robot teams to print larger structures in the future.

Using a specially formulated cement mix suitable for 3-D printing, this new development will allow for unique concrete designs currently not possible with conventional casting.The structure can also be produced on demand in a much shorter period of time.Currently, 3D-printing of large concrete structures requires huge printers that are larger than the printed objects, which is unfeasible since most construction sites have space constraints.Having multiple mobile robots that can synchronise 3D printing means that large structures like architectural features and specially designed facades can be printed anywhere as long as there is enough space for the robot to move around the workplace.

This research project was supported by the National Research Foundation, Singapore (NRF Singapore) and Sembcorp Design and Construction, one of the key industry research partners of SC3DP. Moving forward, the NTU research team will look at integrating even more robots to print larger scale structures,optimize the printing algorithm to maintain consistent performance and improve the curing speed of concrete materials.
