Method for printing 3D structures
The invention comprises a method for forming a 3D object, wherein the method comprises the step of depositing a support structure. According to the invention, the support structure comprises an organic di-acid having a molecular weight of 300 g/mole or less. The invention further relates to an assembly of a 3D printed object and a support structure.
1. A method for forming a 3D object, the method comprising the steps of:
selectively depositing layers of a building material by ejecting droplets of the building material;
depositing a support structure by depositing droplets of a support material, wherein the support material comprises an organic di-acid having a molecular weight of 300 g/mole or less,
wherein the support material comprises at least 85 wt % of the organic di-acid, based on the total amount of support material.
2. The method according to claim 1 , wherein the method further comprises the step of:
removing the support structure.
3. The method according to claim 2 , wherein the support structure is removed using water.
4. The method according to claim 1 , wherein the organic di-acid is glutaric acid.
5. A method for forming a 3D object, the method comprising the steps of:
selectively depositing layers of a building material by ejecting droplets of the building material;
depositing a support structure by depositing droplets of a support material, wherein the support material comprises an organic di-acid having a molecular weight of 300 g/mole or less,
wherein the organic di-acid is glutaric acid.
6. The method according to claim 5 , wherein the method further comprises the step of:
removing the support structure.
7. The method according to claim 6 , wherein the support structure is removed using water.
8. The method according to claim 5 , wherein the support material comprises at least 85 wt % of the organic di-acid, based on the total amount of support material.
