Thanks to the free software application OpenSCAD we can design and create solid objects.
Being it an interactive editor based on a textual description language, it makes OpenSCAD to be the best initial level tool to design and ge tinto the world of •D modelling.
An OpenSCAD document specifies geometric primitives as cubes, cylinders and spheres which are modified to reproduce a 3D model
With OpenSCAD the designer can create precise 3D models and parametric designs easily adjustable through some changes in the parameters.
FreeCAD is an free and open and modular code application which allows an advanced personalization. FreeVAD is directed to the domestic and experienced CAD users and to programmers.
FreeCAD tool has a complete nucleous of geometry that allows to carry out 3D operations. It has also an modular architecture which admits plugins to add aditional functions and a complete parametric model which permits any kind of personalized objects as boxes, spheres, cylinders or cones.
FreeCAD allows the work with nets and it also has a robot simulation module that permits the study of robot movements.
With the irruption of 3d printers the world of design and printing has no limits.
Printing spare pieces for things that we use in our daily life, designing the structure of our dron or robot, printing prosthesis, etc. 3D printing i son the increase and it isa ll about the future that is here. Printing food or even organs is something that sounds as science fiction but that, nowadays, is posible thanks to technological advances.
