3D printing and manual production of a maquette each have their own advantages and disadvantages.
3D printing allows for precise and accurate reproduction of a digital design, which can be particularly useful for complex geometries or intricate details. It also allows for the easy modification of designs and the production of multiple copies with consistent quality. However, 3D printing may be limited by the size of the printer and the materials that can be used, and may require some post-processing to remove support structures or improve surface finish.
Manual production of a maquette, on the other hand, allows for a greater degree of creativity and spontaneity in the design process. It also allows for the use of a wide variety of materials and techniques, such as sculpting, molding, and casting. However, manual production can be time-consuming and may require more skill and experience to achieve the desired result. It can also be more difficult to reproduce the maquette exactly, particularly if modifications are made to the original design.
Ultimately, the choice between 3D printing and manual production of a maquette will depend on the specific needs of the project and the available resources and expertise.
