PolyD 3D Prints on Nylon, Polyamide and Rubber. These robust thermoplastics are ideal for 3D printing of high-quality, functional plastic parts and complex parts such as housings, enclosures and waterproof applications. 

Black UV finishes 

For your 3D printing you can range from raw grey, without any treatment applied, to natural matt with its anthracite grey finish, standard black or even UV Resistant black.


RAL Industrial Painting

Choose the most suitable colour for your 3D print: naval yellow, pure orange, fire red, cobalt blue, sky blue, silver grey, etc. Our finishes resist moisture, light and scratches. They guarantee durability and perfect adhesion.

Oversize Formats 

With MJF technology you 3D print online Complex Parts up to a maximum volume of 380 x 284 x 380 mm. If your part exceeds the printable area, PolyD can section it into several parts to fit the maximum print area and then reassemble them into a single body.
