Three dimensional deposition method to create layers of polymeric material onto an object

A process for producing a three dimensional object made of one or more thermoset polymeric materials having elastomeric properties, said process having at least the following steps:

• providing a thermoplastic polymeric composition having a viscosity >10 Pa.s at room temperature measured according to ASTM D445-11a and comprising at least one cross-linkable thermoplastic polyurethane material containing radically polymerizable unsaturated groups;
• and then
• heating the polymeric composition to achieve a liquid cross-linkable polymeric composition having a viscosity below 4 Pa.s measured according to ASTM D445-11a, and then
• depositing the polymeric composition onto a pre-shaped object using a spray, swirl, or extrusion nozzle and wherein the deposition is performed while the pre-shaped object or nozzle are moving to at least partly coat the pre-shaped object with said polymeric composition;
• and then
• optionally, cooling down the at least partly coated pre-shaped object to room temperature, and then
• optionally, repeating one of foregoing steps, and then
• applying a cross-linking treatment selected from radical curing, UV curing, or heat treatment in order to convert the cross-linkable thermoplastic polyurethane material(s) into a cross-linked thermoset polymeric material(s);
• and
• removing the pre-shaped object from the cross-linked thermoset polymeric material(s) after the cross-linking step, optionally with the aid of a release agent, and wherein the cross-linked thermoset polymeric material defines the three dimensional object made of the thermoset polymeric material.
