Abstract
A method of building up a physical object by additive manufacturing which has the steps of building up the object and at least one support structure layer by layer along a build axis. The support structure supports the object relative to a build platform. During building up the object and the at least one support structure a connection is provided between the support structure and the object by a plurality of layers each of which being a common layer of the object and the support structure.
Claims15
A method of building up a physical object by additive manufacturing, the method comprising the steps of:
- building up the object and at least one support structure layer by layer along a build axis, wherein the support structure supports the object relative to a build platform,
- during building up the object and the at least one support structure, providing a connection between the support structure and the object by a plurality of layers each of which being a common layer of the object and the support structure, and
- providing the connection between the support structure and the object with at least one void that is filled with non-hardened light hardenable material.
(canceled)
A physical object made of a plurality of stacked and cohering layers, wherein a build axis is defined in a dimension along which the layers are stacked and wherein the object exhibits one or more fraction surfaces extending across a plurality of layers, wherein the fraction surface extends entirely across each of the plurality of layers.
