|Abstract: ||In this paper, a non-conventional way of additive manufacturing, curved-layered printing, has been applied to large-scale
construction process. Despite the number of research works on Curved Layered Fused Deposition Modelling (CLFDM)
over the last decade, few practical applications have been reported. An alternative method adopting the CLFDM principle,
that generates a curved-layered printing path, was developed using a single scripting environment called Grasshopper
– a plugin of Rhinoceros®
. The method was evaluated with the 3D Concrete Printing process developed at Loughborough
University. The evaluation of the method including the results of simulation and printing revealed three principal benefits
compared with existing flat-layered printing paths, which are particularly beneficial to large-scale AM techniques: (i)
better surface quality, (ii) shorter printing time and (iii) higher surface strengths.|
