Clear Resin Material Details


General Informations

Clear Resin is a specialized material designed for Stereolithography 3D printing (SLA). In its initial state, Crystal-Clear Resin is a liquid substance that solidifies through UV laser curing. SLA technology results in components characterized by exceptionally smooth surfaces and high precision.

Clear Resin Material Highlights:

  • Exceptional Transparency: Clear Resin is engineered to create parts with remarkable transparency. Objects printed with this material become crystal clear, while internal features, such as conduits, acquire a translucent quality.
  • UV-Sensitivity: Over time, Clear Resin components may experience yellowing when exposed to UV radiation. The application of UV protection coatings can mitigate this effect.
  • Ideal for Fluid and Flow Analysis: Its transparency and translucency make Clear Resin particularly suited for applications in fluid and flow analysis. It is also used for crafting transparent casings, such as those used for product displays.
  • Water Resistance: SLA-printed parts, including those made with Clear Resin, possess high density and water resistance, making them suitable for applications involving immersion and water flow tests. The exceptional surface quality makes them ideal for wind tunnel testing and flow analysis.
  • Not Weather-Resistant: Like many SLA materials, Clear Resin is generally not suitable for outdoor or UV-exposed applications. It is best utilized in protected environments.
  • High Precision: Clear Resin's high precision makes it a valuable choice for simulating injection-molded components and for shape and dimension checks.
  • Support Material: In SLA 3D printing, the support material is the same as the printing material and requires manual removal. This process can impose some limitations on design freedom compared to other manufacturing methods.
  • Post-Processing: SLA parts, including those made with Clear Resin, can undergo high-quality post-processing. These parts can be manufactured with intricate details (as small as 0.05 mm) and sharp edges. With appropriate post-processing, such as painting or coating, they can also be employed for long-term applications.

Pro`s and Con`s


  • Exceptionally Smooth Surface: Crystal-Clear Resin produces parts with an incredibly smooth surface finish, perfect for applications where aesthetics and precision are critical.
  • High Precision: It offers outstanding dimensional accuracy and fine detailing capabilities, making it suitable for intricate designs.
  • Fine Details Possible: With Crystal-Clear Resin, you can achieve very small and intricate details in your 3D prints.
  • Water and Heat Resistance: The material exhibits high-density and water repellency, making it suitable for water applications, such as swimmer testing and water flow analysis. It also offers high heat resistance.


  • Low UV Resistance: Crystal-Clear Resin is not resistant to UV radiation, which can cause degradation over time if exposed to sunlight or UV sources.
  • Not Weather-Resistant: It is generally not suitable for outdoor or weather-exposed applications due to its lack of weather resistance.
  • Manual Support Removal: In SLA 3D printing, the support material used is the same as the printing material and requires manual removal, which can be time-consuming.
  • Brittle Characteristics: Crystal-Clear Resin, like many SLA materials, can be relatively brittle compared to some other 3D printing materials, which may limit its use in load-bearing applications.
