  • Process for producing implants and components by directing shaping
    Patent number: 9034225
    Abstract: The invention relates to a method for producing implants and components by direct shaping. The method includes the steps of producing a mold for the implants or components to be produced, making allowances for changes in geometry occurring during after-treatment after the implants or components are removed from the mold, and, providing partial areas of the mold with a structured surface for transferring this structure to the surfaces of the implants or components. In the method, raw material is introduced into the mold and, after remaining in the mold for a certain period of time, the hardened raw material is then removed from the mold to allow the implants or components to take on the structured surface of the mold as well as its geometry. The demolded implants or components are finally subjected to any after-treatment that may be necessary.
