LEF 300 Odor Issue

Post by RobertB » Fri Mar 06, 2020 2:37 am

Hello Guys First Post Here

Main Issue - We are printing on plywood & MDF and the product smell is horrible. Taking suggestions on how to improve this.

Our Current Idea is a Vented air flow chamber with Wire Racks - Force air in the Bottom & Pull it out on the top end going outside.

Its bit worrying, do you clean your UV light? You should clean the lens with IPA, and not the cleaner and it should be pretty clear. If the UV light isn't strong enough it Isn't curing enough, then this can cause an issue. The problem with woods etc is they are a bit absorbent, I noticed this trying to print beermats once. The smell lingered for weeks. I print onto a lot of plastic, and there is no smell at all. All I use for ventilation is a mixed flow bathroom fan from Screwfix and out the window, we rarely smell the ink in the unit, and even then you have to have your head in the machine.

Has the drain bottled overflowed and spilt ink into the sponge below the drain, I have seen an instance of this previously where the smell became more pungent because of the sitting ink.

Also ensure the lamps are clean as the lack of curing could cause the smell.

There is a post cure option too, send the UV lamp again for more absorbant materials

Thanks for the Input Joe,

We did the Extra UV Lamp Scan but it still had a strong odor & took forever, Thank you for the suggestion though. It seems like its printing fine & Clear but the strong odor is just intense. We are gonna give it one more shot before we put the printer up for sale. Any suggestions on our ventilation and curing area ?? We plan on creating a small enclosure with wire shelves & have a fan force air in the bottom & than a exhaust fan at the top to remove the air (Working on it this weekend). We are hoping that the moving air will help the printed boards loss there odor faster. We printed parts two weeks ago that still have a strong odor to them & we also have some that smell fine with little to no odor. Im up for trying any suggestions before we take the big hit on selling. We mainly work with Birch Plywood & Painted MDF.

You could also seal the wood, with PVA or similar?
Airing rack sounds good, sure it would help.
