Introduction

Resin 3D printing, also known as stereolithography (SLA) or digital light processing (DLP), is a widely adopted additive manufacturing technique that leverages photopolymerization. This technology enables high-resolution production of intricate designs and is recognized for its precision and surface finish quality.

Principles of Resin 3D Printing

Resin 3D printing operates on the principle of photopolymerization, where liquid resin is selectively cured by a light source to build objects layer by layer. The key parameters influencing the process include light intensity, exposure time, and layer thickness.

• Light Intensity: Typically measured in mW/cm², affecting the curing depth and speed.
• Exposure Time: Dictates how long the resin is exposed to the light, influencing layer bonding.
• Layer Thickness: Often ranges from 25 to 100 microns, impacting detail and speed.

Technical Process

The technical process of resin 3D printing involves several structured phases:

1. Design Creation: Models are designed using CAD software and converted to STL files.
2. Preparation: The printer’s build platform is coated with a thin layer of resin and set to the desired starting position.
3. Printing: A light source cures the resin layer by layer according to the design specifications.
4. Post-Curing: Printed objects often require additional curing under UV light to achieve optimal mechanical properties.
5. Cleaning and Finishing: Excess resin is removed, and supports are detached to finalize the product.
