We have a Fuse 1 30+ Nylon 12 and sometimes there is only a small defect in a large part. Its a cosmetic issue for sure and we want to be able to fix it!
I was hoping to fill it with an epoxy mixed with some of the powder, has anyone tried this? any help would be appreciated!
That looks like you have contamination issues in your hopper. If you have not already, I recommend that you cover the hopper opening with a lint-free cloth or a 150 sieve mesh. I am using the latter on my hopper secured with magnets.
As it happens however, I am trying this proposed fix today to try and recover from another print defect. I have simulated your defect to test this proposed fix. I will have the results in the morning when the epoxy cures.
I am using Loctite 2 part epoxy and Nylon 12 from my Fuse Blast Waste Hopper.
Thank you so much for the advice! I will definitely try a mesh sieve, did you buy one and cut it to size? or does formlabs sell one?
I acquired this one from McMaster-Carr 9319T185 and cut it in half as it matches the specifications of the Fuse Sift mesh. I shared a picture this on this thread
Good news! The fix works. It appears to work better on my simulated defect where I sliced into the part with a knife to recreate your defect. It also appears to work with the “Orange Peel” defect though multiple coats appear to be required.
Here is a before photo, showing the mild “orange peel” and a simulated contamination defect.
For the epoxy mix, I simply added spent nylon 12 powder to the 2-part epoxy until it looked mildly grainy. The nylon 12 is from the waste hopper of the Fuse Blast so it would have a small amount of spent glass bead powder.
That looks great! I have some epoxy here and going to give it a try! Will post results when I get them!
