How is 3D printing resin made?

Ph.D. Chemist Explains 3D Printer Resin

What is resin for 3D printing?

Resin or synthetic resin are UV-curing liquid plastics. These materials are used in stereolithography 3D printers. The photosensitive resin can be cured by laser or light and thus transformed into a solid model. The liquid resin is exposed at the desired locations with the 3D printer, curing the resin.

Where do resins come from?

Resins are produced in special resin cells in plants, and are also produced when an injury occurs to the plant. Resins can be produced through the bark of a tree, the flowers of an herb, or the buds of a shrub. Think of a pine tree that has a missing tree limb.

How resin is manufactured?

Most common epoxy resins are produced from a reaction between epichlorohydrin (ECH) and bisphenol-A (BPA), though the latter may be replaced by other raw materials (such as aliphatic glycols, phenol and o-cresol novolacs) to produce specialty resins. The epoxy resins can be obtained in either liquid or solid states.

How is synthetic resin made?

Synthetic resin is organic compound made by combining carbon atom, hydrogen atom, and a small quantity of oxygen atom, sulphur atom through certain chemical bond.

What is natural resin?

Natural resin is a product that is derived from plants, contrary to a synthetic resin that is typically produced via chemical synthesis. Natural resins have been widely utilized in the field of mummification.

Can I put my resin printer outside?

A 3D printer can be used in a hot or cold garage, but it needs to have temperature regulated in some kind of enclosure and some protection against drafts. I wouldn’t recommend putting a 3D printer outside because you can get significant temperature changes too rapidly, resulting in bad quality prints.
