Abstract
The present invention relates to the use of a composition comprising isosorbide diglycidyl ether and a curing agent as a sacrificial support, to a sacrificial support comprising isosorbide repeating units, to methods for producing the sacrificial support of the invention and to uses of the sacrificial support of the invention for producing three-dimensional objects.
Claims16
A process for preparing a three-dimensional object, the process comprising:
- producing a sacrificial support comprising a polymer including isosorbide ether repeating units and not comprising a bisphenol A based epoxy resin, the sacrificial support being produced by a process comprising:
- providing a composition comprising isosorbide diglycidyl ether and a curing agent,
- casting the composition in a mould,
- at least partially curing the composition, and
- separating the cured composition from the mould to obtain the sacrificial support;
- depositing a material to at least partially cover the sacrificial support, wherein the material comprises a polymer;
- and
- removing the sacrificial support from the deposited material to obtain the three-dimensional object.

A process for preparing a three-dimensional object, the process comprising:
- producing a sacrificial support comprising a polymer including isosorbide ether repeating units and not comprising a bisphenol A based epoxy resin, the sacrificial support being produced by a three-dimensional printing process using a composition comprising isosorbide diglycidyl ether and a curing agent;
- depositing a material to at least partially cover the sacrificial support, wherein the material comprises a polymer;
- and
- removing the sacrificial support from the deposited material to obtain the three-dimensional object.
