From the Vertical to the Horizontal: 3D Printing Without the Requirement of Formwork

Abstract

The objective of this article is to develop a methodology to print selfsupporting, synclastic and anticlastic double curved surfaces tending to the horizontal from the vertical without requiring formwork. To achieve this goal the following was studied, fist place, the definition, the stresses and behaviors of double curved surfaces. Second place, he performance and applications of 3D printing in the construction area, in three companies of this field. From the bibliographic review, the variables are identified to propose an algorithm to print synclastic and anticlastic surfaces in 3d. Finally, the feasibility of the method to print these types of surfaces in 3d was proven by printing four prototypes which confirmed the proper operation of the algorithm, along with showing aspects to improve at the time of printing.
