3D modelling is an efficient and environmental-friendly way to develop prototypes, visualise product ideas and simulate functionality pre-production. Designers can refine ideas and make countless iterations before a product is finalised.
You can do this in a few different ways
Physical modelling in card / paper / other materials, which is then painted
Digital and physical modelling using the laser cutter or the 3D printers
Totally digital modelling using online CAD programmes
