🔬 What is resin for 3D printing?

Resin is a photosensitive liquid material that solidifies when exposed to ultraviolet (UV) light. This process, known as photopolymerisation, enables superior detail compared to filament. SLA, DLP and MSLA printers from leading brands such as Anycubic and Elegoo use this technology to build objects layer by layer with extreme precision. In the example below you can see the printing process using Anycubic Resin.

🧪 How does photopolymerisation work?

Unlike 3D printing with filament (FDM), where the material is melted and deposited in layers, in resin printing the material is a photosensitive liquid that hardens when exposed to light.

This process occurs in several phases:

1️⃣ UV Exposure: The 3D printer projects ultraviolet light onto a layer of liquid resin, activating its chemical photoinitiators so that it solidifies.

2️⃣ Layer formation: Each layer adheres to the previous one, building the object layer by layer with incredible precision.

3️⃣ Lifting and repetition: The print platform rises slightly after each layer, allowing the uncured resin to flow and prepare for the next light exposure.

4️⃣ Post-processing: Once printing is complete, the part must be washed and cured under additional UV light to achieve its final strength. 🔎 Differences between resin printing and filament printing (FDM)
