How Long Does Uv Resin Take to Cure in 2023

Multiple factors go into determining how long it takes UV resin to cure. These include what type of chemicals you use and the ambient temperature. UV resin should always be handled in an area without direct sunlight, as this can cause premature curing. Keep reading our article to learn more about How Long Does Uv Resin Take to Cure?

Understanding UV Resin

UV resin can harden or cure when exposed to ultraviolet (UV) light or direct sunlight. This resin is used to make jewelry, dentures, and other 3D parts.

Understanding UV Resin

Clear liquid resin can be mixed with other colors or materials. It dries to a shiny, attractive appearance. It can coat retractable plastic paper, fill small silicone molds, or coat metal bases.

The UV resin is different from epoxy resin. You don’t need to mix the resin with any other components such as an accelerator or catalyst for it to cure.

UV light can help heal the resin. A UV lamp or flashlight is required. This lamp could also be used to dry nail polish.

The excellent advantage UV resin has over epoxy resin’s fast-drying speed is that it can be used in various applications. You don’t need to mix it with other additives.

Here are some of the main characteristics.

  • Without long waiting periods, you can have your condition cured in minutes.
  • Without mixing with other components, such as epoxy resin, it can be fixed by UV light and sunlight.
  • Transparent color
  • Available for immediate use
  • Non-toxic materials.

How Does The UV Resin Work

How Does The UV Resin Work?

To pigment the UV resin, you must place it in a silicone or plastic container. We will then need to use a remover to mix the resin until it reaches the desired color.

After applying the resin to the base, a UV lamp/flashlight must be used to direct the light at the wax. This will allow it to dry completely.

The thickness of the piece will determine the drying time. It is essential to understand that the mold must have transparency to allow light to penetrate the resin to dry it thoroughly. It can encapsulate objects within the resin, allowing you to work in layers.

Resin should always be treated with care and taken into consideration.

  • Keep the container tightly closed to prevent the resin from hardening.
  • It would help if you preferred to work in well-ventilated areas.
  • Keep the resin out of reach of children.
  • It is essential to use gloves when working.
  • Use a transparent mold.

What Methods Can I Use To Cure A Resin?

It is known that UV light can cure the resin. However, other curing methods can speed up or slow down the process. We will be reviewing some of the most popular curing methods.

Professional Curing Device

A professional curing machine can be used to cure the resin. The device will completely wrap the object in a container and emit a uniform UV light of approximately 405 nm.

The uniformity of light makes curing the model remarkably consistent across its entire surface. This reduces the chance of over-curing certain areas of the object.

The UV Light Lamp

The most popular method for curing resin is using a UV light lamp.

These lamps are much more affordable than professional curing devices. This technology can quickly cure nearly any type of resin and is both inexpensive and powerful.

The main drawback of this method is the inability to cure all surfaces. People usually manually rotate the model to fix its sides.

To counteract these shortcomings, you can create a curing zone with a cardboard container with reflective material on both sides.

Aluminum foil can be used as a reflective material. This will allow the UV lamp to reflect around your object, improving the uniformity of the cure.


Imagine that you don’t have the funds to purchase a professional UV lamp or curing device. There is always an alternative.

You need natural UV light from the sun to get the treatment you need. However, keep in mind that UV from sunlight can be intense but not as powerful as UV provided by professional devices or lamps.

This means that while the sun can cure resins, it will take longer. While curing resins with UV lamps takes only a few minutes, curing with sunlight can take several hours.

How Long Does 3D Resin Take to Cure Under UV Light

How Long Does Uv Resin Take to Cure?

If you use a high-UV wavelength and your resin 3D printer is very small, it takes just minutes to cure them. Average-sized prints can take up to 30 minutes under the same conditions.

Lower UV intensities (e.g., It will take longer to cure 3D images that have lower UV intensities (e.g., from the sun), and larger prints will also take longer to cure.

These figures are not necessarily correct. If your 3D resin is not ready after the prescribed time, you can continue curing for a little longer. The time it takes to cure 3D resin depends on its type, color, model size, and curing method.

Even though the material may cure in just 15 minutes at a UV curing station, it can take many hours to cure under sunlight.

The sun can cause color changes in resin when it is cured. High-end curing and washing machines can cure the same material in a matter of minutes.

The settings that you choose will affect the efficiency and duration of the curing process. The ideal location will produce the best results in the shortest time possible.

Factors Affecting How Long It Takes 3D Resin To Cure

The duration of post-curing can be affected by many factors, including surface area, geometry, color, and 3D resin models. The UV strength and temperature levels of your 3D resin will also impact the time it takes to cure.

We will be looking at these factors in more detail in the sections below.

Geometry and Surface Area

More extensive resin 3D printing takes longer than smaller or smaller prints. Complex 3D parts take longer to cure.

It would help if you used rotating plates in your UV chambers to make 3D resin prints. These chambers cure tough 3D resins more quickly and evenly.

Resin Color

Explicit materials take less time than opaque materials such as black and gray. Clear resin, which is transparent or transparent, takes less time as UV light penetrates them more easily. The color resin is more challenging to penetrate, so it takes longer.

UV Strength

Lower wavelengths (e.g., Direct sunlight UV rays take longer than high wavelengths, such as unique UV curing stations.

Some UV stations use small lights, while others use large ones. Although larger curing lights use more power than smaller ones, they cure 3D resins quicker.

You should expect to remain longer for the post-curing process if exposed to sunlight. The UV strength can be affected by weather conditions. The UV strength isn’t stable, so it is difficult to predict how long curing will take.


Because the resin cures faster with high heat, the polymer network of resins is more open to cross-linking. The curing time will decrease if the temperature rises. Also, the UV chambers’ light bulbs provide heat which speeds up curing.

How Dangerous Is UV Resin?

Resin can be very dangerous for human health and the environment, even before being fully cured. The skin is particularly vulnerable to UV resin.

UV resin can cause skin problems if it is exposed excessively or regularly. Any body area can be injured if it comes into direct contact with resin that has not been correctly or untreated. However, you should not be exposed to resin in any way other than by accident.

Is UV resin toxic? The environment is also highly toxic by UV resin. Unsafe and improper disposal are the main threats to environmental safety.

Resin is particularly dangerous for aquatic ecosystems. Resin is especially dangerous for marine ecosystems. Doing so could cause harm to other aquatic animals. This could lead to the destruction of entire ecosystems and plant life.

Can You Cure UV Resin with an LED Lamp?

Any LED lamp can treat UV Resin with 4 watts and more. UV LED light can be used to cure UV resin. This is a cost-effective way to cure miniature 3D resins like nails. However, the UV light might not be strong enough to cure larger models or some types of resins.

Experts recommend LED resin to be the best UV resin. LED polishes are less likely to form air bubbles. It takes much less time to cure. LED resin also has a lower price.

How Do You Wash And Cure Resin Prints?

Before curing a resin model, you need to wash it in an Isopropyl Alcohol bathtub after printing it. Submerge the resin print into an Isopropyl Alcohol container.

Swirl the 3D printed part around for 3 minutes to remove the extra resin. You can cure the model by heating it and exposing it to UV light.

It can be messy if you have to clean 3D resin by hand. Many people now use all-in-one solutions to cure and wash resin prints. These machines can wash resin prints and emit UV light to cure them.
