Working on a solution to that darn PVA

Posted · Working on a solution to that darn PVA

Hiya,

I have been one of many struggling with PVA absorbing moisture ad dessamating the nozzle.

so here is my solution that I will give a go once I have the quote and recieved the acrylic parts.

as an interim i created this 5a333fdae97f7_PVACASSING.thumb.jpg.addf53a06f7a8d32eb2a7aa8b1d26834.jpg

pva-reel-casing

there is little friction but works well, I have been printing over a week now and it's still achieving good prints.

but I want something with a bit more elegance and also will make more for other filaments as I have added runners to the base so I can slot the case into a rack. (one for storage and the other for printing)

I will be sharing the new one once I have finished it and used it for a bit.

enjoy

Thank you @SandervG.

I hope so. I think moisture is the primary cause of everyone's problems.

I might strip my old on out to see how we can resolve it once the problem exists because £114,- is a lot to spend on something that you assumed worked straight out of the box. (which I did) could you apply a supplier warning or a sticker on the UM3 to emphasise the need to ensure a controlled environment for the PVA? just so that new buyers fully realise the gravity of moisture and PVA.

    Hi, what the moisture of your place? I notice that you are in the UK, and I know it's usually rainy place. But I also know that in the UK, strict indoors air-cons make me feel a little dry. So I wonder the exact number of humidity if you can provide. Thanks.

    hiya,

    I have no idea. I don't have a measuring device.

    I am a heavy home user where the printer is going all day every day with little down time.

    the blockage is cause for two reason; Too hot or moisture. if using cura heat shouldn't be a problem so moisture is the go to problem. I think any level of moisture will at some point cause an issue as it is accumulative. so short of Sahara dry condition we will struggle at some point eventually.

    kind regards
