General info

  • A. What is stereolithography?
    1. Stereolithography is an additive manufacturing technology based on a process of photo-polymerisation for laser-sensitive resins or liquid materials. The object is formed as each of its layers solidifies instantly under the laser beam. This system overcomes all the obstacles posed by traditional technologies in the manufacture of complex, hollow or undercut objects. Watch the video on our YouTube channel
  • B. What is additive manufacturing?
    1. The 3D printing field comprises many technologies, but the basic concept shared by all is additive manufacturing. This is the addition of layers of material to create an object rather than removing material from a solid block as is the case with most traditional technologies.


  • A. How long do the materials or resins last?
    1. One year in the unopened packaging.
    2. In the closed machine or away from UV light sources, it should be used within 2 months.
  • B. Can I reuse the material in the tank?
    1. Of course, this is one of the distinctive features of our technology. The material solidifies in a quantity proportional to the object being manufactured, without any additional waste. The material left in the cartridge can be used to make other objects. The cartridges are immediately interchangeable, allowing for rapid changes in material with maximum flexibility of use.
  • C. What are the supports for?
    1.  The supporting elements are made from the same material used to produce the object and are generated automatically by the Nauta software. They support the object during the creation phase to prevent structural collapse.
  • D. What characteristics do the materials have?
    1. DWS materials are photo-polymers filled with elastomers, nanoceramics and other functional components. In their initial state they are liquid and solidify thanks to laser photo-polymerisation.
  • E. Do I need to use protection?
    1. Thanks to our innovative system, the interchangeable cartridges containing the liquid material are simply inserted, meaning none of the material requires direct handling.
  • F. How do I clean the tank after use?
    1. The cartridge is designed to be used until empty. Any solid residues in the work area should be removed by hand, using the tools provided in the kit supplied.
  • G. Can you send me samples?
    1. To receive a standard sample, please write to
