High-speed printing processes are the low cost of production of the element. In addition, material ABS and PLA are the cheapest available on the market for materials used in the building blocks of 3D technology, extremely resistant to high temperatures (120-140 ° C), available in many colors (possible use of transparent materials). Also possible to print from Nylon and PVA (soluble bioplastics). Technology less precise, the material quite difficult to handle, does not allow for very precise printed elements, moving and complex geometry.
