UV chamber

UV chamber

The UV chamber, also known as UV box or UV curing unit, is an essential piece of equipment for the post-processing of 3D printed resin parts. After printing, photosensitive resin requires additional exposure to UV light to fully cure and reach its final mechanical and aesthetic properties.

Why use a UV chamber for 3D printing?

In resin 3D printing (SLA, DLP, or LCD), the object is formed layer by layer through photopolymerization. However, once out of the printer, the piece is still soft or sticky: it must be cured in a UV chamber to harden completely.

This post-curing process is essential to:

• Improve the mechanical strength of the parts
• Stabilize shapes and prevent deformation
• Enhance the aesthetic finish (shine, clarity, uniformity)
• Reduce risks of detachment or breakage

How a UV box for resin works

A UV box for 3D printing is typically equipped with UV LEDs (often 405 nm) that evenly distribute light over the entire piece.

Some chambers rotate the part for even exposure. Others combine washing and curing functions (Wash & Cure stations), like the popular models from Anycubic or Creality.

How to choose your UV chamber?

The choice of a UV curing chamber depends on several factors:

• The maximum size of parts to be treated
• Compatibility with your resin 3D printer (LCD, DLP, SLA)
• A rotating platform for even exposure
• The type and power of LEDs (e.g., 405 nm for most resins)

Brands like Anycubic, Elegoo, and Creality offer reliable and efficient UV chambers for 3D printing, suitable for hobbyists and professionals alike.
