Technologies and materials

Every 3D printing technology runs its own families of materials. The pairing you choose – technology and material together – is what decides the strength, accuracy, finish, durability, flexibility and cost of the finished part.

Start with the printing technology

Materials are not interchangeable across processes – each one exists only in the technology it is made for. Pick the technology first to see which materials actually run on it.
