Getting started with 3D printing: How to choose the right resin?

Buy your first resinAfter 3D printing, it is time to consider a key factor: the choice of resin. Indeed, the resin used plays a determining role in the quality and characteristics of the print.

Discover the different types of resins

Before you start choosing a resin, it is important to understand the different options available on the market. Each type of resin has unique properties and characteristics suited to specific applications. Here are some of the most common types of resin:

Standard resin: These versatile resins offer a good balance between print quality, ease of use and price. They are perfect for beginners and general object creation.

High performance resin: These resins offer superior mechanical properties such as improved tensile, flexural and impact resistance. They are suitable for demanding applications such as creating functional parts or prototypes.

Engineering resin: These resins have specific properties such as biocompatibility, heat resistance or flexibility, fusibility (for investment casting), electrostatic discharge, flame retardancy, etc. They are suitable for special applications such as printing medical parts, molds or seals.

Resin art (or miniatures): These resins are designed to produce prints with extraordinary detail and color. They are ideal for creating sculptures, statues and decorative items.

Choose the right resin for your project

The choice of resin depends on several factors, including the final print application, desired physical properties, your experience level, and your budget. Here are some tips to help you make your choice:

Consider the application: Determine the end use of the printed object. If you need strong, durable parts, you may want high-performance resins. For decorative pieces, artistic resin may be more suitable.

Physical properties: Consider the physical properties required for your application, such as tensile strength, flexibility, heat resistance, or biocompatibility.

Experience level: If you are a beginner, choose a standard, easy-to-use resin. Engineering resins may require more expertise, particularly setting up print settings when die-cutting (although most manufacturers provide profiles).

Budget: Resin prices vary widely. Define your budget and research the options that best suit your needs.

Compatibility with your printer: Make sure the resin you choose is compatible with your3D printer compatible. Each printer has its own resin requirements. While most current resin 3D printers use a wavelength of 405 nm, some use a wavelength of 385 nm and therefore require specific resins. Additionally, some 3D printers use proprietary material cartridges.
