Definitions
- the invention relates to a method for the layered construction of models as well as material systems for use in such methods.
- stereolithography solidification of monomeric liquids with a high-energy beam
- selective laser sintering fusion of particulate material with a high-energy beam
- 3-D printing process All these methods allow the comparatively economical production of molds for prototype construction.
- the 3-D printing process also allows superior speed when using multiple controllable nozzle printing devices.
- the application is not limited to the prototype area. There are even series components economically producible bar.
- the solidification of the initially liquid for printing materials can be done for example via UV radiation.
- two or more component systems can be used, which are brought together and solidify on the construction platform. Since the entire volume of construction must be generated by inkjet printers, but this process is relatively slow and therefore suitable only for smaller components.
- a powdery material is selectively connected.
- the particulate material is brought up and smoothed onto a workpiece platform with a coater in thin layers, for example.
- a printhead solidifies selective areas on the powder layer based on the component data stored in computers. This process is repeated again and again until the component is completed and can be removed from the un solidified particulate material.
- the solidification of the particulate material takes place here by gluing the individual particles together.
- Polymerizing systems have proved to be particularly useful since once introduced material does not have to leave the molding again. Thus, in this regard, no loss and thus delay to be feared.
- polymerizing adhesives are known for high binding forces.
- a problem with the RPS is the start of the reaction.
- a component must be liquid for processing in the drop generator. This may only begin to solidify with the application to the powder. For this purpose, a component must be present in the powder, which triggers the start of the reaction.
- the powder is a mixture of different particles or the component is contained in the particle.
- an initiator component is in RPS dibenzoyl peroxide in question. This represents a source of danger as a powdered pure substance. It tends to explode in the case of mechanical impact. Therefore, mixing in the base powder is critical.
- a second possibility are so-called bead polymers in which peroxide is present in the individual particles.
- Such a powder is completely uncritical in handling.
- RPS also have the property that the binder tends to inhibit oxygen. In this case, the polymerization is disturbed by the oxygen present in the air. As a result, the adhesive forces are greatly reduced when air enters. This is a considerable problem, in particular in 3D printing, in which, due to the process, large effective surfaces occur. In order for the reaction to proceed at room temperature, catalysts are added. These often pose a significant health risk.
- the object of the invention is therefore in different aspects a method, a binder and a material system for the layers To provide design of models that does not have the disadvantages of known 3D printing process, in particular RPS, or at least reduces or completely overcomes the disadvantages of the prior art.
- the invention relates to a method of layering models, wherein in a construction area a first material and then selectively a second material are applied in layers, respectively, and these two application steps are repeated until a desired model is obtained; the two materials form a solid at a suitable mixing ratio; the first material comprises a particulate material; and the second material is applied via a printhead and wherein the first material, the second material and / or the particulate material comprises one or more diamines and one or more dicarbonyl compounds as a binder.
- the invention relates to a use of one or more diamines and one or more dicarbonyl compounds in a method of layering models.
