Yeah and as its mm when sold here. Unsurprising why I could not see it.

Thanks for the help.

For us beginners in 3d printing.

What do the numbers in nema moters actually mean.

I recognise they go up in size/power. But being from the UK. And Nema being a US standard. I’d love a guide.

Yeah thanks for the bad news.

I am using these https://www.printables.com/model/50375-desiccant-silica-hygrometer-spool-container-modula

So should be able to tell. Treating the cheap, crappy meters as binary. IE, if RH% above minimum readable the bag has failed.

Yeah UK ain’t a swamp. But 50 to 60% rh is common.

So I’m thinking I may have to think that way.

I am rapidly discovering. That spools do not seem to arrive dry.

Also, desiccant will not dry a spool. It keeps the air dry and will prevent a dry spool becoming wet. With ASA, I am learning you always need to dehydrate before first use. But am hoping using desiccant and vacuum bags will limit the time needed when reusing an open spool.

Just to confirm. Hygroscopic does not mean the material is unsuitable for wet conditions as a finished product.

Your comment suggested that was your assumption.

The issue is that FDM (and all plastic 3d printing) depends on the molecular bods reforming as plastic is melted and reshaped. Almost all physical materials absorb moisture from the air. But some more than others. Highly hygroscopic materials when melted below glass transition temps. The moisture within the molecular bonds dramatically affects the materials’ ability to rejoin and reform those strong bonds. This results in some very odd effects on the final product, making effective production impossible.

The general rule is heat (30 to 90c depending on material) and time is needed to remove the absorbed water before printing. As for how long. Well for every 5c below the perfect temp for your material, the time doubles. This time starts at 4 to 12 hours depending on the material. (data is online) So yeah the time can become days if not using the perfect temp.

I am currently struggling with this myself with ASA. As its my first time trying it. (im new to all this).

This. Just require all gov products and documentation to be open. (unless military and even then open were possible)

Creating a new distro is not needed. Let users or nation gov bodies select or create as they see fit.
