| Description | L'invention concerne une méthode de production d'un objet physique par fabrication additive. La méthode comprend les étapes consistant à fournir un matériau primaire durcissable à la lumière (11), construire l'objet (100) en durcissant successivement des parties du matériau primaire durcissable à la lumière (11) par irradiation des parties avec de la lumière, revêtir au moins une partie de l'objet (100) avec un revêtement perméable à la lumière ou un matériau de protection de l'oxygène ; et irradier l'objet revêtu (100) avec de la lumière et ainsi post-durcissir toute matière durcissable à la lumière (11). |
| Abstract | A method of making a physical object by additive manufacturing. The method has the steps of providing a light hardenable primary material (11), building up the object (100) by successively hardening portions of the light hardenable primary material (11) by irradiating the portions with light, coating at least a part of the object (100) with a light permeable coating or oxygen protective material; and irradiating the coated object (100) with light and thereby post-hardening any light hardenable material (11). |

| Claim | What is claimed is: A method of making a physical object by additive manufacturing, the method comprising steps of: (a) providing a light hardenable primary material, wherein the light hardenable primary material is liquid or pasty; (b) building up the object by successively hardening portions of the light hardenable primary material by irradiating the portions with light; (c) coating at least a part of the object with a flowable coating; and (d) irradiating the coated object with light and thereby post-hardening any light hardenable primary materia The method of claim 1, further comprising a step of cleaning the object from the coating by moving the object and thereby generating a mass inertial force in the coating. The method of claim 1 or 2, further comprising a step of cleaning the object from excess material by moving the object and thereby generating a mass inertial force in the excess material, wherein the step of cleaning the object from excess material is performed before the step of coating the at least a part of the object with a coating, and wherein the excess material is formed by at least one of the light hardenable primary material and a light hardenable secondary materia The method of claim 2 or 3, wherein in the step of cleaning the object from the coating or from excess material, respectively, the moving of the object is a rotation of the object. The method of claim 4, wherein the rotation is performed about at least a first rotation axis and a second rotation axis, wherein the first rotation axis and the second rotation axis have different orientations. The method of any of the preceding claims, wherein the object comprises a workpiece for providing a dental restoration from the object. The method of claim 6, wherein the object further comprises a fixture portion that does not form part of the dental restoration, wherein the fixture portion is configured for retaining the object in a post-processing device for cleaning the object. 8. A system for making a physical object, being configured for performing the method of any of the preceding claims. An object that is made of at least a light hardened material, comprising a flowable coating made of a composition comprising between 50% by weight and 99% by weight glycerol and between 1% by weight and 49% by weight fumed silica. |
