Abstract
The present invention describes a method for building modes in layers, wherein a first material and subsequent thereto selectively a second material are applied in layers in a build space, and these two application steps are repeated until a desired model is obtained. The two materials form a solid object in a suitable mixing ratio, the first material including a particulate material and the second material being applied with the aid of a print head. The first material, the second material and/or the particulate material include one or more diamines and/or one or more dicarbonyl compounds as tree binder.
Claims21
A method comprising:
- i) depositing a layer of a first material including a particulate material;
- ii) selectively depositing a second material are applied in layers in a build space, and these two application steps are repeated until a desired model is obtained;
- over the layer of the first material;
- iii) reacting a diamine compound and a dicarbonyl compound in a condensation reaction for bonding a portion of the particulate material.
