Hi everyone,
I’m looking for advice on UV protection for a room with windows where an SLA printer and UV resin are used regularly.
The room itself has been in use for a while, but until recently it was winter, with generally lower UV levels, and there used to be a nearby building that cast shadow onto the windows. That situation has now changed, and the room receives direct sunlight.
This has already caused an issue for me in the past: with a small SLA printer, I once briefly removed the protective cover, and the resin in the vat partially gelled due to ambient UV light. That’s why I’m now looking for a more robust solution before continuing regular use.
Ideally, I want to keep the room bright and usable, so fully blocking or darkening the windows isn’t my preferred option. I’m currently considering UV-protective window films that block most UV radiation while remaining largely transparent.
I’d be especially interested in:
Whether UV window films are effective against resin-relevant UV wavelengths
If such films are sufficient on their own or still require additional measures
Recommendations for specific products or specifications
Real‑world experience, especially over longer periods
As a worst‑case fallback, I’m aware that completely darkening the windows and switching to artificial lighting would solve the problem, but I’d prefer to avoid that if a reliable non‑darkening UV protection solution exists.
If anyone here has dealt with a similar situation or tested UV protection films in a resin printing environment, I’d really appreciate your insights.
Thanks a lot!
