Resing Printing

What is Resing?

Resin for resin printers, also known as photopolymer resin, is a liquid material used in Stereolithography (SLA) 3D printing. Photopolymer resins are designed to harden or cure when exposed to ultraviolet (UV) light. In SLA printing, a vat of liquid photopolymer resin is exposed to a highly focused UV light source, which causes the resin to cure and solidify, forming a single layer of the printed object.

Photopolymer resins come in a variety of types, each with its own unique properties and characteristics. Some common types of photopolymer resins include:

  • Standard Resin: A versatile, general-purpose resin that is suitable for a wide range of applications.
  • Flexible Resin: A flexible, rubber-like material often used to create parts that need to bend or flex.
  • Transparent Resin: A clear, transparent material that is often used for creating optical lenses, light pipes, and other transparent parts.
  • Hard Resin: A strong, stiff material that is often used for creating high-strength parts, such as gears, tools, and mechanical components.
  • Castable Resin: A special type of resin designed for casting processes, such as lost-wax casting.

The choice of resin will depend on the specific needs of the project, including the desired strength, flexibility, transparency, and curing speed. Photopolymer resins are available in various colors, and some resins can also be dyed to achieve a desired color.
