Impresora 3D de casas y estructuras

The global cost of construction and infrastructure has been 11.4 billion dollars in 2018 and is expected to rise to 14 billion in 2025. As of last year, the general price in material cost has been of 7.53%, especially due to the cost of steel which increased in 33.47%. For 2021, there is a total of 195545 projected sales, corresponding to 34.8 billion COP. Regarding the environment, considering that cement production generates 2.2 billion tons of CO2 emissions yearly, which equals to 8% of the global production, it’s important to think in sustainable ways to continue construction that can significantly reduce the emission of greenhouse gasses (GHG), without impacting the industrial household construction sector. 3D printing is a process in which physical objects are generated through the deposit of a material in fine layers from a digital model. This alternative has the potential to mitigate the carbon footprint and price rises of the traditional construction materials. This project has as objective to develop an additive manufacturing CNC mechanism/system that can construct robust, economic, sustainable, and fast buildings and able to be deployed in-site to cover the demand of a wide spectrum of horizontal, residential, commercial and auxiliar construction (Condominiums, offices, furniture, cabins, or design structures). Having this in mind, a design process; from specifications to part of detailed design, for a gantry platform and screw-extruder 3D printer was conducted.
