Novel CH2 domain template molecules wherein donor loops from a database of domains are transferred to a CH2 domain scaffold. At least one or up to three loops from a donor are transferred to the CH2 domain. The donor loops may be chosen based on length, e.g., the donor loop may have a length that is similar to that of a structural loop in the CH2 domain scaffold.

The invention discloses a full-color sandstone dye for 3DP (three dimensional printing) and a forming method of a full-color sandstone dye product. The full-color sandstone dye comprises 15%-25% by mass of dye powder, 60.0%-85.0% by mass of main body powder, 2.0%-15.0% by mass of an accelerator and 8.0%-20.0% by mass of a binder. A traditional dye is subjected to chemical grafting, surface active points are increased, and the dye is mixed with the accelerator, the binder and the like. According to a process, the adhesiveness of the dye to the surfaces of sandstone particles is improved effectively while the dye dispersing effect is improved, and the bleeding fastness and the coloring intensity are improved in a manner combining physical adsorption and chemical bonds. A dye reagent can be mutually dissolved with various cosolvents and is high in forming speed, and rapid forming of full-color sandstone for 3DP can be realized. The process is simple, the forming cycle of the product is short, the production efficiency is high, the designability is high, and the full-color sandstone dye and the forming method are suitable for realization of large-scale and industrialized 3DP technology.
