  • Patent number: 9688023
    Abstract: A process for additive manufacturing of a resorbable implant to be implanted into a patient includes providing a biocompatible resin including a liquid light-polymerizable material that is resorbable after polymerization and an initiator. The process further includes actuating an additive manufacturing apparatus to expose an amount of the biocompatible resin to light to at least partially cure the exposed amount of biocompatible resin to form a layer of the resorbable implant and actuating the additive manufacturing apparatus to expose at least some additional amount of biocompatible resin to light to at least partially cure the exposed additional amount of biocompatible resin to form an additional layer of the resorbable implant and to at least partially overcure previously cured layers to cause at least some interlayer binding between the previously cured layers and the additional layer.

  • Patent number: 7831328
    Abstract: The invention relates to a method for producing a three-dimensional object by solidification of a material solidifiable under the action of electromagnetic radiation by means of energy input via an imaging unit comprising a predetermined number of discrete imaging elements (pixels), The method comprises performing solidification with exposure using bitmap mask. The bitmap mask may be formed from a stack of bitmap data provided by an overlap analysis of a three-dimensional volume completely or partially enclosing a three-dimensional model of at least a part of the three-dimensional object to be produced. Alternatively, bitmap mask may be formed from a two-dimensional data set comprising overlap information. Solidification may be performing with exposure using bitmap mask generated “on the fly”. The invention is also directed to devices, and a computer and a data carrier useful for performing or executing the method.
