What is 3D Print Resin Material For SLA?
3D print resin material is a type of material that is used in 3D printing processes, which utilize stereolithography (SLA) or digital light processing (DLP) technologies. Unlike traditional 3D printing materials such as ABS or PLA, resin 3D printing material is a liquid that is cured by light exposure. This liquid resin is placed in a vat, and a light source is used to selectively cure the material, layer by layer until the object is complete.
Resin material comes in various formulations, each with its own set of properties and characteristics. Some of the most common types of resin material include standard resin, flexible resin, and high-temperature resin. Each of these materials has unique properties that make them suitable for different applications.

Biocompatibility of SLA 3D Printing Resin Materials
The biocompatibility of 3d printing resin material refers to its ability to interact with living tissue without causing harmful effects such as toxicity, inflammation, or rejection. In 3D printing, biocompatibility is especially important for medical and dental applications where the printed parts come in contact with human tissue.
To ensure biocompatibility, resin manufacturers typically test their products according to international standards and guidelines. The ISO standards classify the biocompatibility of materials into three categories based on the level of risk:
Class I: Materials that are considered to have a low risk and are typically used in applications that have limited contact with the body, such as packaging materials.
Class II: Materials that are considered to have a moderate risk and are used in applications that have prolonged contact with the body, such as medical devices that are implanted or used in direct contact with tissues or fluids.
Class III: Materials that are considered to have a high risk and are used in applications that are critical to the patient’s health, such as implants or devices that come into contact with blood or other bodily fluids.
Over these classifications, some regulatory bodies, such as the U.S. Food and Drug Administration (FDA), have additional requirements for the biocompatibility testing of materials used in medical and dental applications. It is important to choose a resin material that has been tested and certified for biocompatibility for use in these applications.
