Polymer material in 3D Printing

Photosensitive resin is composed of polymer monomers and prepolymers. Due to its good liquid
fluidity and instant light curing characteristics, liquid photosensitive resin has become the first
choice for 3D printing consumables for high-precision product printing. The photosensitive resin
has fast curing speed and excellent surface dry performance. The appearance of the product after
molding is smooth, and it can be transparent or semi-transparent in a frosted state. The
photosensitive resin has the characteristics of low odor and low irritating ingredients, which is very
suitable for personal desktop 3D printing systems.
Polymer gel
Polymer gel materials such as sodium alginate, cellulose, animal and vegetable glues, peptone, and
polyacrylic acid are used for 3D printing. Under a certain temperature and under the action of
initiators and crosslinking agents after polymerization, a special network polymer gel product is
formed. When subjected to changes in ionic strength, temperature, electric field and chemical
substances, the volume of the gel will also change accordingly, which is used for shape memory
materials. The gel swells or shrinks and undergoes volume conversion, which is used for sensing
materials. The controllability of the gel mesh can be used for smart drug release materials.
