What Is Resin For 3D Printing?

Resin or synthetic resin are UV-curing liquid plastics. These materials are used in stereolithography 3D printers. The photosensitive resin can be cured by laser or light and thus transformed into a solid model. The liquid resin is exposed at the desired locations with the 3D printer, curing the resin.

What is resin used for in 3D printing?

Resins are a big part of materials research within 3D printing, and are ideal for quickly producing parts with a high level of accuracy. 3D printing resins are liquid photopolymers, primarily used with technologies such as Stereolithography (SLA) and Material Jetting.

What material is used in resin 3D printing?

SLA 3D printers use light-reactive thermoset materials called “resin.” When SLA resins are exposed to certain wavelengths of light, short molecular chains join together, polymerizing monomers and oligomers into solidified rigid or flexible geometries.

Does resin print 3D printing?

Stereolithography (SLA) is the oldest form of 3D printing. It works by exposing a layer of photosensitive liquid resin to a UV-laser beam; the resin then hardens in the desired pattern, and the object is built layer by layer until it is complete. This allows you to print a model with extremely fine detail.

Is resin A plastic?

Key Differences. The resin is simply a form of unprocessed plastic while plastic is the final product for using further. Solid resin has a bit more versatility regarding how it can be formed. It is also supposedly easier to repair.

What are resin prints good?

Resin 3D printers are popular for producing high-accuracy, isotropic, and watertight prototypes and parts in a range of advanced materials with fine features and smooth surface finish.

Is 3D resin toxic?

UV resin used in 3D printing is very toxic, not only for people but also for the surrounding environment. Any body part directly exposed to the resin can be harmed, and improper treatment of the resin can harm animals and the environment. UV resin can be very harmful, but few are aware of its effects.

Are resins toxic?

Epoxy and resin can be poisonous if they are swallowed or their fumes are breathed in.

What type of plastic is 3D resin?

Acrylonitrile butadiene styrene (ABS) — A terpolymer fabricated by polymerizing styrene and acrylonitrile with polybutadiene, ABS is another plastic commonly used in 3D printing.

What types of 3D resin are there?

  • Standard Resin. Our most recently added resin is Standard Resin.
  • Gray Resin. Gray Resin, previously known as Prime Gray, is a very smooth resin, much smoother than almost all other 3D printing materials, and easy to paint.
  • Mammoth Resin.
  • Transparent Resin.
  • High-Detail Resin.

What materials do I need for a 3D printer?

  • Plastic. Out of all the raw materials for 3D printing in use today, plastic is the most common.
  • Powders. Today’s more state-of-the-art 3D printers use powdered materials to construct products.
  • Resins.
  • Metal.
  • Carbon Fiber.
  • Graphite and Graphene.
  • Nitinol.
  • Paper.

Which is better plastic or resin?

Although, plastics are more durable than resins. Plastics also contain lesser impurities than resins and are more stable. So, by comparison, we can see that resin is better than plastic for the environment.

What is the difference between 3D printing and resin printing?


There are two main liquid-based materials primarily used in 3D printing: resins and thermoplastic filaments. FDM (Fused Deposition Modelling) printers use filaments, while resins are primarily used for Stereolithography Apparatus (SLA) technology.

How do you make 3D printer resin?

Are resin prints Food Safe?

Is resin food safe? The answer is no. Substances may migrate from SLA parts which makes none of the resins and printed parts food safe by default. While some resins for dental and medical applications are certified biocompatible, that doesn’t mean that they’re food safe.

What temperature can 3D resin withstand?

High Temp Resin offers the highest heat deflection temperature (HDT) among Formlabs resins and is suitable for printing detailed, precise parts with high thermal stability. The new formulation, shipping now, has an HDT of 238 °C @ 0.45 MPa and improved elongation to decrease brittleness.

Is resin a strong material?

Resin is a very strong material.

What is PETG resin?

PETG resin is a thermoplastic polymer commonly used as an insulator in electrical applications. Other common applications are: Thermoformed Plastic Clamshells. Cosmetic Packaging.

How loud are resin printers?

Resin 3D printers are usually quiet compared to filament 3D printers, but they do still emit a decent amount of noise from the stepper motors (50 dB).
