What are the best resins for Dental 3D printing

Introduction to dental 3D printing

3D printing is a technology that is revolutionizing the field of dentistry. This innovation allows the creation of models and personalized dental prostheses quickly and accurately, facilitating the professionals' work and improving the patient's experience.

Benefits of 3D printing in dentistry

In addition to saving time and money, 3D printing in dentistry offers other advantages, such as the reduction of errors and the possibility of creating more comfortable and aesthetic prostheses. However, to guarantee the quality of the final product, it is crucial to choose the right resin.

Types of resins for dental 3D printing

There are several types of resins available on the market, each with its advantages and disadvantages. Below, we present the three main categories of resins used in dental 3D printing.

Methacrylate based resins

These resins are quite common and have an excellent cost-benefit ratio. They are derived from polymethyl methacrylate (PMMA), a polymer widely used in dental prostheses.

Advantages of methacrylate

  • Low cost
  • Easy handling
  • Good mechanical resistance
  • Dimensional stability

Disadvantages of methacrylate

  • Lower accuracy compared to other materials
  • May cause irritation in sensitive patients

Resins based on methacrylic acid ester

Methacrylic acid ester is a newer and advanced material compared to methacrylate. It offers better accuracy and biocompatibility.

Advantages of Methacrylic Acid Ester

  • higher precision
  • Better biocompatibility
  • Suitable for sensitive patients
  • Less shrinkage during polymerization

Disadvantages of Methacrylic Acid Ester

  • higher price
  • Requires specific equipment for processing

Acrylate urethane based resins

Urethane acrylate resins are a high-performance option for dental 3D printing. They combine the advantages of methacrylate and methacrylic acid ester, providing excellent quality and durability.

Advantages of urethane acrylate

  • High mechanical strength
  • Dimensional stability
  • Biocompatibility
  • Suitable for long term applications

Disadvantages of urethane acrylate

  • high price
  • More complexity in handling

Factors to consider when choosing a resin

When choosing the ideal resin for dental 3D printing, it is important to consider several factors:


The resin must allow the creation of models and prostheses with precise and well-defined details.

Dimensional stability

The resin must be able to maintain its shape and size after polymerization, without deformation or dimensional changes.


The resin must be biocompatible, that is, not cause allergic reactions or irritation in patients.

Mechanical resistance

The resin needs to have adequate mechanical resistance to withstand the wear and pressure exerted on the prostheses and dental models.

print speed

The resin must allow a reasonable printing time, without compromising the quality of the final product.


Choosing the ideal resin for dental 3D printing depends on the specific needs of each application and the desired characteristics of the final product. Considering the aforementioned factors, methacrylic acid ester and urethane acrylate based resins are more advanced options and suitable for most situations. However, methacrylate resins can be a viable alternative in cases where cost is a determining factor.


  1. Is there any specific resin for making dental crowns and bridges?

Yes, there are specific resins for the manufacture of crowns and bridges, generally developed based on methacrylic acid ester or acrylate urethane, which offer greater precision and mechanical resistance.

  1. Are dental resins safe for allergic patients?

Most dental resins are biocompatible and safe for allergic patients. However, it is always important to check the manufacturer's information and consult the dentist before use.

  1. How long does it take to print a denture using 3D printing?

The time required to print a dental prosthesis depends on the type of resin, the equipment used and the size and complexity of the prosthesis. In general, the process can take from a few hours to a day.

  1. Is any special treatment necessary after 3D printing a dental prosthesis?

After 3D printing a dental prosthesis, it is common for a post-cure process to be carried out, which may include cleaning the part, removing supports and final polymerization in a UV light chamber. This process is important to guarantee the strength and dimensional stability of the prosthesis.
