The sections where the plaster was destroyed were mechanically removed with rough metal scrubbers, scrapers and warm washing. A water drainage system was installed to drain and clean water from the socle part of the building. The plaster was removed step by step.
A Design Sociotechnical Making of 3D Printing
Published in Steinar Killi, Additive Manufacturing, 2017
3D printing technology is often used for making prototypes and models. The plaster material used in the process is fragile, brittle, and slightly porous. The material is therefore well suited to grinding and polishing. The relative fragility of the material makes it unfit for functional or mechanical prototypes. When constructing for 3D printing, a wall thickness of less than 2 mm and details of less than 1 mm should be avoided. As the part is fragile during unloading, any unsupported walls or cantilevered parts should be at least 3 mm thick. Part orientation in the fabrication bed may affect tolerances and should be considered in the process.

Plaster is made from crushing and dehydrating gypsum. One major building product that uses plaster is gypsum board. It is made by mixing plaster with various fillers to produce a paste which is then formed between sheets of paper board and dried. The energy coefficient for gypsum board is about 60 to 80 MJ m−2 (5300 to 7000 Btu ft−2).8,16

After 7 days from applying the primer the surface was treated by gypsum plaster (Knauf Rotband, Knauf Sp. z o.o., Warszawa, Poland). The gypsum plaster was prepared by mixing dry powder with water. In this research, the ratio of the gypsum plaster-water was 20 kg–12l. The components were mixed together using a low-speed drill. Ten millimeters of ready gypsum plaster was applied on the concrete blocks with firm pressure by a trowel. When the gypsum plaster was firm enough, the surfaces were scoured with a sponge float. Finally, the surfaces were troweled progressively to obtain a smooth matt finish (Figure 3c). The setting time of gypsum plaster was 14 days.
