Enclosure & Air Filtration for Formlabs SLA, Wash & Cure

General Discussion

Hey everyone,

Managing resin VOCs and IPA evaporation, especially when opening Wash lids is a constant challenge in shared lab spaces.

We wanted to share a quick look at a custom enclosure setup we designed for Safran in France to house their Formlabs printers, Wash, and Cure stations:

Key features we integrated for safety & air quality:

  • Air Extraction: Negative pressure for IPA & VOC capture.

  • UV Safety: Opaque/UV-blocking panels to prevent ambient light curing inside the enclosure.

  • Safety Integration: Built-in smoke detectors and fire safety setup.

  • Lab Organization: Lower shelving for bulk resin and IPA storage.

Free STLs: If you’re building your own ventilation setup, we put together a set of free 3D printable STL files for air intake grids and duct mounts you can print yourself: https://www.alveo3d.com/en/free-stl-files/

Looks great!

Just a warning - if those panels aren’t actually rated to block out 405nm (ie. they’re just plain acrylic or PC) - it’s going to let 405nm UV through. Most standard acrylics and PCs are great for blocking a lot of lower wavelength UV but it will still let a lot of 405nm through. I’ve tested this before with a 405nm UV meter.

Otherwise cool work!

For those who have less budget and time, using an off the shelf grow tent also works great and is what I’ve done in my space.
