  • Publication number: 20210054125
    Abstract: The invention relates to a method for producing an object from a precursor, comprising the steps: I) depositing a radically cross-linked resin on a carrier so that a layer of a construction material connected to the carrier is obtained, said layer corresponding to a first selected cross-section of the precursor; II) depositing a radically cross-linked resin on a previously applied layer of the construction material so that an additional layer of the construction material is obtained, which corresponds to a further selected cross-section of the precursor and which is connected to the previously applied layer; III) repeating step II) until the precursor is formed, wherein, at least in step II), the deposition of a radically cross-linked resin is carried out by allowing energy to act on a selected region of a radically cross-linkable resin, corresponding to the respectively selected cross-section of the object, wherein the radically cross-linkable resin has a viscosity (23° C.
