3D Printing Resin

What is resin

Broadly speaking, resin refers to a polymer or prepolymer used as a plastic substrate. Generally insoluble in water, soluble in organic solvents. According to the source, it can be divided into natural resin and synthetic resin.

Its relative molecular weight is uncertain, but it is usually high. At room temperature, it is solid, medium solid, pseudo solid, and sometimes liquid organic matter.

The role of resin in 3D printing

As an important industrial raw material in the world, resin has played an important role in various fields. The same is true in 3D printing technology. Resin is a very important and commonly used 3D printing material. For example, the printing material of SLA, ProJet and LCD is resin.

Classification of resin

Natural resin and synthetic resin

According to the source, there are natural resin and synthetic resin.

Natural resin refers to the amorphous organic substances obtained from the secretions of animals and plants in nature, such as rosin, amber, shellac, etc.

Synthetic resin refers to the resin products obtained by chemical synthesis of simple organic substances or chemical reaction of some natural products, such as phenolic resin and polyvinyl chloride resin. Synthetic resin is the main component of plastics.

Adduct and polycondensate

According to the synthetic reaction, the resin can be divided into adduct and polycondensate.

Adduct refers to the polymer prepared by addition polymerization. The chemical formula of its chain link structure is the same as that of monomer, such as polyethylene, polystyrene, polytetrafluoroethylene, etc.

Polycondensation refers to the polymer prepared by condensation polymerization. The chemical formula of its structural unit is different from the molecular formula of monomer, such as phenolic resin, polyester resin, polyamide resin, etc.

Thermosetting resin and thermoplastic resin

According to the properties, it can be divided into thermosetting resin and thermoplastic resin.

Thermosetting resin: unsaturated polyester, vinyl ester, epoxy, phenolic, bismaleimide (BMI), polyimide resin, etc. This kind of resin is generally used for FRP

Thermoplastic resin: polypropylene (PP), polycarbonate (PC), nylon, peek, PES, etc.
