The ability of architects to present the quality of their work as realistically and detailed as possible is becoming ever more important. Projects on the scale of models can take concrete shape with the aid of 3D printing, so that proportions and the overall effect of the designs are immediately apparent to the viewer. Epoxy resin-infiltrated parts not only have an outstanding mechanical stability but they also make it possible to produce copies that represent the architectural concepts true to the original down to the last detail. Printed models often also supply exact templates for sculpting or historic preservation efforts.
