Definitions
- the second curing means is a light source, wherein the deposited second printing material is illuminated during at least a further period of the fourth step
- the light source in particular a UV-LED, emits UV-light.
- the use of the further light source has the advantage of correcting defects immediately.
- the further light source emits IR-light.
- the light of the further light source is directed by light guiding means to the defect. Consequently the light of the further light source retransforms the first printing material from being in the second state to being in the first state selectively.
- the first printing material is transformed from being in the first state to being in the second state immediately after the first printing material is replaced, for instance by immediately cooling the first printing material. As a result the first printing material being again in the first state may be removed or replaced. Concluding the quality of the finished three-dimensional structure, in particular its surface is improved, advantageously.
- a layer comprising the first printing material is less thick than a layer comprising the second printing material.
- the first printing material being in the first state and the second printing material being in the third state are deposited such that the second printing material being in the fourth state at least partially wraps the first printing material being in the third state.
