S1. Make molds. Use nylon powder to print with 3D printing equipment to make different types of molds. The shapes of the molds include multi-bud branches, mushroom-shaped bulges, cauliflower-shaped bumps and other common shapes in clinical cases.

S2. Pour 10g of konjac flour and 2g of gelatin sponge into 100g of deionized water and heat to boiling. Konjac flour, gelatin sponge and deionized water can form a colloid with conductive properties, wherein the konjac flour plays a role of gelling, and the gelatin sponge is a hydrophilic colloid mainly including gelatin protein and sponge skeleton protein.

S6. Add 6g of isopropylacrylamide and 5g of acrylamide in sequence and stir until completely dissolved. Since there are hydrophilic amide groups and hydrophobic isopropyl groups in the isopropylacrylamide molecule, the homopolymer has a relatively good Good properties such as low critical solution temperature allow materials to be fully dissolved. Acrylamide is mainly used to make water-soluble polymers, where it acts as a binder.

S7. Add 0.2 g of N,N,N',N'-tetramethylethylenediamine as a reaction accelerator and stir until completely dissolved; using N,N,N',N'-tetramethylethylenediamine as a reaction accelerator can accelerate the reaction and molding of the gel, thereby achieving the purpose of improving the efficiency of making polyp replacement blocks.

S8. Pour the polyp replacement block 300 into the mold, cool it, and take it out after molding. This completes the production of the polyp replacement block 300.
