Before printing with a Resin 3D Printer, did you know there are 7 types of resin? From general-purpose resins for prototyping, to Tough resins similar to PP, high-temperature resistant resins (200-300°C), ultra-hard resins mixed with ceramic, Wax resins for jewelry, flexible resins similar to rubber, and even high-standard dental resins. Choose correctly for good results and no problems later. Read full details on all 7 types in this article.

Currently, Resin 3D Printers are highly popular due to their diverse applications, including dental prototypes, jewelry, engineering, and more. The key material that ensures effective and high-quality results is “resin.” However, there are 7 types of this material, each with different uses. To understand and choose the most suitable one for your work, a detailed study is necessary.

Introducing 7 Types of Resin Used with Resin 3D Printers

1. Engineering Resins or Tough and Durable

This group of resins is highly popular for use with Resin 3D Printers. It is suitable for materials that are wear-resistant and flexible, with mechanical properties similar to polypropylene (PP), featuring high elongation, low modulus, and high impact resistance. This results in parts with a glossy, smooth surface, high resistance, and no deformation. It is ideal for consumer goods, various packaging, bearings, snap fits, and flexures, as well as products requiring exceptional flexibility.

2. General Models, Prototypes: Standard Resin or General Resin

This type is suitable for creating prototypes and general models, serving as a starting point for all brands. It is easy to print with high clarity. These resins offer a wide range of color options and are highly versatile, divided into 3 main categories:

• General purpose resins
• Fast-printing resins, which print 5 – 10 times faster than normal, though with slightly lower detail than general resins.
• Water-washable resins, which can be cleaned with plain water, saving on cleaning chemicals and solutions.

3. Heat Resistant Resins

These are used with Resin 3D Printers for applications requiring heat resistance, such as fluid flow devices, mold prototypes, tooling, or thermoforming. Most of these applications require high thermal stability and operate at high temperatures, tolerating temperatures of 200 – 300 degrees Celsius.

4. Extra Hard Resins or Stiff Resins

This group offers exceptional hardness, often referred to as Standard/General Resin. However, they do not immediately break upon impact. Some types are mixed with Ceramic or other fillers, making them stronger than usual and resistant to deformation. They are ideally suited for printing thin walls or thin-walled structures.

5. Jewelry Resins or Wax Resin

Resins used with Resin 3D Printers in this category are suitable for jewelry applications that contain wax or Polymer Wax blended according to the manufacturer's formula. When these resins are burned at temperatures exceeding 700 degrees Celsius, there is almost no soot from combustion, or so little that it's equivalent to 0 – 0.05%.

6. Flexible Resin/ Elastic Resin/Rubber-like Resin

This group has rubber-like characteristics, allowing engineers to easily and quickly simulate soft-touch rubber parts. They have a low tensile modulus but very high elongation at break. They are suitable for applications requiring compression or bending. Their flexible hardness has 2 values: Hardness decreases with lower values. Lower letters generally indicate more softness than higher letters, for example, Shore 75A is softer than Shore 75D. They have diverse uses such as rubber stamps, packaging, and creating wearable prototypes like clothing or shoes.

7. Dental Resins

Finally, this group is also used with Resin 3D Printers, specifically in the dental field for making models or for direct use within the human body, such as retainers or endodontic treatments that require devices to be worn in the tooth cavity. These resins are high-priced and require strict adherence to manufacturer standards to ensure customized and high-quality results.

We hope that after learning about these 7 types of resins used with Resin 3D Printers, you will be able to choose the most suitable one for your work, ensuring efficient production and preventing future issues.
