    Hi all,

    I recently entered the world of 3d printing. Bought a Flashforge Adventurer 3, since I wanted something that would be easy to get going and had an enclosure so ABS printing was possible.

    Included with the "tools" they supply, there is a tiny package of some white grease, obviously intended for lubricating the various rods and things. It's probably enough for a tiny application on each rail/screw and that's it.

    What should I use after that tiny package runs out? What do you guys apply to your 3D printers? And more importantly, where did you get it? There are plenty of recommendations out there, but the brand names don't seem to be available in Australia.

    Thanks!

    I use the same lubricant you use for bike chains. Some teflon stuff.

    I don't recommend the aerosol spray, but a drip on solution like this

    Looks good. Where did you buy that?

    Ahh, that's the missing link. I've only looked at Bunnings and super cheap auto.
    Thanks!

    White grease is most likely white lithium grease so that might be another option.

    Oh, didn't notice the age of this thread when I replied LOL. Just ordered my first 3D printer last night and was browsing around and must've gone back further than I thought.

    All good. Might be handy for someone else with the same question.

    That 3-in-1 oil is not great. It's very thin and tends to dissipate too quick. There is also the issue that any oily/greasy surface will tend to attract and hold dust, increasing wear.

    Dry lubes are better in that regard, there is a variety of spray PTFE (teflon) products at bunnings that spray on like a damp powder and then dry off. eg:
    https://www.bunnings.com.au/wd-40-specialist-150g-anti-friction-dry-ptfe-lubricant_p6100410 and
    https://www.bunnings.com.au/selleys-150g-ezy-glide-dry-lubricant-aerosol_p1235305

    The garage door lube is also a reasonable option. Once again it has to deal with attracting dust so it's designed to dry off. Not sure if it's plastic compatible though. https://www.bunnings.com.au/3-in-one-300g-professional-garage-door-lubricant_p6100232

    Oh, damn. Thanks for the tip.

    I'll try some of those bunnings options. Cheers!

    I use the Tamiya moly grease. It's expensive on a flat per gram wise but we don't have a lot of the gun related lubes the US guys seem to get for cheap, so aside from the other hobby brands that come and go it's been my go to for metal small mechanisms. You don't need to use a lot at all for it to work so the big tube actually lasts ages. It isn't a full dry lube but the grease base is very light and not particularly sticky.

    Most of the auto moly lubes (a lot of auto lubes for matter) are far too thick and sticky for things like 3D printers.

    Also toothed belts properly tensioned won't really have any issues with a little bit of lube contamination.

    What gun lubes are commonly recommended? Most remain wet or are a grease which I would've thought was too much for a printer. FWIW you don't need to have a firearms license to buy lube just because it's marketed towards gun use.

    I've used a jar of Penrite moly grease as a substitute for the Tamiya stuff. Way cheaper and no difference in appearance, texture or viscosity that i can see from just handling it. Have used it in the diffs of RC cars etc.

    Is it this stuff?
    https://www.penriteoil.com.au/products/molygrease#/

    Will have to grab some next time my moly runs out - although by the progress on the 10 gram stick that might be a couple of years yet :lol:

    The gun stuff I'm not sure about the brands; only have come across it when looking into the topic, apparently there's equivalents to the moly and boron nitride greases that are marketed for gun mechanisms and as bullet lube, although when I looked most of it wasn't widely sold within Australia.

    I'll have to check the tub to be certain but I'm reasonably confident that's it. Disclaimer: I have heard that Tamiya changed their moly grease a few years ago. My tubes, if I still have any, are decades old and that's the stuff I'm familiar with and comparing to.
