Resin 3D print guide

Executive Summary

What is resin printing?

Resin printing is a 3D printing technology where a liquid plastic (resin) is cured using UV light. Unlike FDM printers that melt and extrude plastic filaments, resin printers build the model layer by layer by curing liquid plastic in a vat using a UV light source.

Resin printers are known for providing a high level of detail on the model and a smooth surface, which can be difficult to achieve with FDM printers. Resin printers are also usually more precise than FDM printers, making them suitable for printing small and detailed items. Resin printers typically have a higher resolution than FDM printers, meaning they can produce more complex models with smoother surfaces.

Resin can have different properties, such as being flexible, strong, transparent, or coloured. This means you can print a wide variety of different models with different characteristics.

Resin printers require more attention to detail and more post-processing than FDM printers. After printing, you need to remove the model from the build plate and clean it in isopropyl alcohol. Subsequently, you also need to cure the model in UV light before you can use it. It’s also important to remember that resin is toxic and can harm your health, so it’s important to have good ventilation and wear protective gear when working with it.

What should I be aware of with resin printing?

When printing with resin on your 3D printer, there are several things you need to be aware of:

  1. Environment: Resin is toxic and can harm your health, so it’s important to have good ventilation and wear protective gear when working with it.
