NTU Singapore develops technology that can 3D-print a bathroom unit within a day According to Assoc Prof Tan Ming Jen,” 3D-printing a bathroom unit could help manufacturers halve their production time while lowering transport costs, carbon emissions, and materials wastage. Less space is required to create and store the same number of PBUs in land-scarce Singapore since conventional PBUs take about two weeks before they can be ready.
By being able to print-on-demand, companies can save on their inventory costs as well as manpower costs, as they don’t have to hold as much stock and their workers can be redeployed to do higher-level tasks. This approach improves the safety of the workplace since robots are doing the construction of the bathroom unit.
According to team lead from Sembcorp Design and Construction, and Sembcorp Architects & Engineers Er Lie Liong Tjen, “3D printing technology allows concrete to be printed and customized. The complicated shape of a PBU and its walls can be developed and printed at a faster pace to satisfy the needs of individual customers as no formwork or molds are required, whereas conventional construction of PBUs with concrete or lightweight wall panels always limit the possibilities of design. In addition, 3D printing can build curvilinear profiles rather than rectilinear forms”.
Air NZ uses a 3D printer for speedy. According to Air New Zealand,” has teamed up with components and systems provider Moog, Microsoft and ST Engineering on a world-first experiment which has the potential to transform aerospace supply chains by leveraging 3D printing and Moog’s blockchain enabled VeriPart™ process to create a point of use, time of need a digital supply chain.
The proof of concept has seen Air New Zealand order a digital aircraft part file from Singapore-based ST Engineering. The digital file was immediately sent to an approved printer, operated by Moog in Los Angeles, downloaded and 3D printed before being installed within hours on an Air New Zealand Boeing 777-300 aircraft ahead of its scheduled departure”.
