| abstract |
The invention discloses a 3D printing molding wax which can be cross-linked, has high printing speed and high printing fineness, and can be used for casting and models at the same time. It comprises the following components in parts by weight: 20-90 parts of unsaturated wax, 5-30 parts of adhesive, 0.1-1 part of nucleating agent, 0.1-1 part of compatibilizer, 1-20 parts of photosensitive resin, 0.5-1 part of photoinitiator, 0.5-1 part of crosslinking agent, 0.1 part of antioxidant ‑0.5 part, toner 0‑1 part. The present invention also provides a preparation method of the above molding wax. The invention has the characteristics of good lost wax performance, fast printing, high printing precision and cross-linking. After cross-linking, it has the advantages of good toughness, high strength and good rigidity. It can be applied to both lost wax casting and printing models at the same time. field. |
