Resin - What is it?

Resin is a liquid material. In nature, resins are mainly found in trees and plants. Artificial resin occurs in 3D printing. It consists of liquid polymers and other additives. Resin represents a reactive intermediate stage in the production of thermosetting plastics. Moreover, resin has long been used in model and prototype construction. Furthermore, resin has been used in model making for a very long time. The first SLA-3D printer (stereolithography) used resin for rapid prototyping since the end of 1980.

Among other things, resin contains these components:

  • Photoinitiators
  • photopolymers
  • Dyestuffs (optional)

FAQ – 3D printing with resin


What are the advantages of resin 3D printing (SLA, DLP and LCD) over fused layer 3D printing (FFF and FDM)?

Resin 3D printing has many advantages over FFF/FDM 3D printing:


  • Resin 3D printers have a very high resolution – 3D prints have fine structures and details with a high surface quality.
  • DLP and LCD 3D printers can work very fast if you intelligently fill the building platform with 3D models, because the entire layers are cured and not just the individual tracks are welded one after the other.
  • Resin 3D prints consist of well-connected layers, not sheets. Due to the material properties different from thermoplastics, resin hardens and becomes very strong and durable in all directions.

What are the disadvantages of 3D printing with resin?

To get a better idea if 3D printing with resin is a good solution for you, here is an overview of the disadvantages of resin 3D printing:

  1. Many resins smell strong before and during processing - the smell ranges from fir cone-like to strong chemical.
  2. After 3D printing, the surface of the components is covered with resin residues and sticky.
  3. Finished and already cured 3D prints cure - depending on the material - by UV radiation. This can cause the components to become brittle.
  4. Depending on the type of material, resin is still more expensive than the thermoplastics used for filaments.

Use these tips & tricks to minimize the disadvantages of resin 3D printing and benefit from its major advantages:

  1. 3D print with resin only in well ventilated rooms. We don't recommend you live or work in a room where a resin 3D printer is currently working or where the filled resin tank is.
  2. Only handle the resinous components with protective gloves. Clean the objects by placing them in a bath filled with IPA (isopropanol/isopropyl alcohol) for approx. 10 minutes and then let them dry. Then put them in a UV post-curing chamber or in sunlight for curing.
  3. Paint or varnish your cured 3D prints to protect them from the weather and UV rays.
  4. Resin material costs are constantly decreasing. Think about how you can save material with intelligent component and support structure design. Material costs are minimal, especially for small components.

Is resin a plastic?

No, resin is not necessarily a plastic. Resin is also found in nature. For example, pine trees contain resin and natural resins in their bark. These resins give pines, for example, their typical smell. Furthermore artificial resins, which are used in 3D printing partly smell after fir cones. In contrast to resins from nature, however, these are artificially produced and therefore belong to the group of plastics.

What is resin used for?

The artificially produced resins play a role in several applications. Among other things, resin is used to produce adhesives, lacquers, composite materials, electrical housings and thermosets. These materials are used in numerous industrial and everyday applications.
