Is my intake fan melted?

Just cleaned my machine & while cleaning the intake fan noticed little bits missing on the fan blades. Also it looks slightly melted. I’ve never had a fire or flare up while using it. Had it since November 2020. Can I get a replacement intake fan?

Not sure what fan you’re talking about since the intake is underneath down on the right side. This looks like your air assist fan from behind the printer head. I don’t think that’s melted…it looks like lots of caked on residue.


Get some mascara brushes and or q tips and work on cleaning up the blades. It is hard to tell if there is any damage with all the gunk.


Agree with the above, curious what material you have been using in the machine to deposit that residue…? It looks particularly gooey.
As long as the fan is spinning, a good cleaning should take care of that, it doesn’t look like the blades are heat damaged, just a heavy deposit.


Comments above are correct that you are looking at your assist fan, not your intake.

I received a GF that had the same residue. This is what the intake fan looked like and the assist was in the same condition:

So I dont think its melted. Idk what all the previous user was cutting but it was not easy to get off (q-tips and any brush did not do any good). 3M Novec Electronic Degreaser had no effect on it either. I ordered replacement fans as backup and decided to just put the old fans in a tub of simple green (why not when I have backup ones on the way). Keep in mind that simple green is not really good with aluminum and you need to take caution with it. So I let them soak for about 10 minutes and then rinsed them really well with distilled water and let them dry for a few days. They looked brand new and I ended up putting them back in the machine (although I still have the backups just incase).

So up to you but you can try and clean it or you also could order a replacement.


This is exactly what I needed!! Thank you for the information. I’m going to order a replacement and try to give the original a good clean.

You’re right, it is the air intake fan. Any suggestions on how to remove the gunk? It seems stuck really well and tears the q-tips when I try to clean the blades.

I had that issue a lot at one time and also thought it had been melting. What I did with the machine unplugged and without even removing the carriage was to hook up a vacuum hose to the metal outlet of the fan and pull air through. I had discovered that hand sanitizer did a great job of dissolving the gunk on the work and so pumped it on the fan which was taken up immediately by the vacuum and dissolving all the gunk along the way. Letting the vacuum continue after I was done every trace of sanitizer was removed as well.

This is what my fan looked like…


Oh no, I’m sorry to hear about the trouble @danifruit.

I’ve extracted your machine logs, and I’m unable to find any errors related to your Air Assist Fan. This is excellent news!

You can try to deep clean your fan with a lint-free cloth with isopropyl alcohol.

If you’d prefer, we can absolutely create an invoice for a replacement part. The Air Assist Fan comes on a Carriage Plate with an X-Axis belt as well and is $150.50 plus taxes and shipping.

If you would like to proceed, let me know and I’ll send a separate email to you to gather some personal information.

Just knocking the dust & bits of wood have done a great deal for resuming cutting. I don’t thing the fan needs replacing but I’m still having a time removing all the built up residue. I haven’t tried isopropyl alcohol yet but will give it a go.

It’s great to hear that removing some of the dust and debris has helped. We’ll leave this thread open while you try some additional cleaning. Please let us know how it goes!

I use 99 per cent isopropyl alcohol it cleans really good . I use a small paint brush just keep it wet and brushing

gunk from cleaning wish i took befor and after
