Technology of 3D printing and possibilities of use in building elements

The paper deals with 3D printing technology and its use in construction. There are several 3D printing technologies, where the main aspects that need to be considered are the choice of printing material. Examples of printing material include polymers, resins, concrete, steel or ceramics. The print material can be chosen in the form of an eco-friendly polymer material, where examples include PLA (PolyLactic Acid), rPLA (Recycled PolyLactic Acid), PETG (Glycol-modified Polyethylene Terephthalate). It is also possible to choose from a range of other polymers, wherein the material includes for example ABS (Acrylonitrile Butadiene Styrene), PE (PolyEthylene), PP (PolyproPylene), PVA, etc. The choice of the printing material itself is closely linked to the choice of the 3D printing printer itself, with each printer considering the material used in 3D printing. In the construction industry, polymers can be used by creating special atypical moulds, which can be further used in laboratory tests or, for example, in the field of architecture for interior design elements or exterior furnishings in the form of furnishings.
