Abstract
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.
Claims8
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.
