Worked out the other day I'd probably have paid for one many times over with small plastic parts I've bought, or could make to use. Not interested in doing firearm parts, just bit's n pieces around the home and whatnot.
Does anyone have any specific info on locally available ones, not too interested in going the Temu route etc. Jaycar is about the only shop I can get to locally easily, but there may be others I've not thought of yet.
Doesn't have to be huge, small desktop would be fine and I'm pretty competent with PCs and design software so I have no worries there as I've used a number of CAD programs for other stuff before.
Thanks

Yep; I've had two of them so far, and seriously contemplating my third...
Mine were both FDM printers, rather than resin-bath.
First one (Flashforge Creatoor Pro 2016) had 2 extruders, though I had a lot of difficulty keeping the second one working properly, and eventually removed it.
Creator Pro has a build volume of around 4.5 litres max.
Second one(still in use) is a Flashforge Guider IIs, with the High-temp Mod and Swiss Hot End Mod, which gives it a print temp of up to 300 degrees, and build volume is around 21 litres max.
First question would be what sort of plastic you intend to print?
PLA (The most common starting plastic) is great, is biodegradeable, but starts to deform in temps as low as the high 40's.
It's also vulnerable to direct sunlight(UV).
But it's hard when printed, and it prints well, so handy if you dont expect it to be exposed to high temps.
Also REALLY handy to get your hand in on printing plastics.
There are 'Blends' of PLA that include wood or various metal powders, to give them additional characteristics, but the heat/UV restrictions dont really change.
So, next is either ABS, or (my preference) ASA.
Difference between these 2(in everyday use) is that ASA is more resistant to degradation in direct sunlight.
But both ABS and ASA need more heat in the build process, and usually require both a heated platform, as well as an enclosure to control the temp around the print.
However; neither ABS or ASA are perfect; they arent biodegradeable at all, and so you need to consider how you keep your worksite from becoming covered in microplastics.
Fumes from ABS and ASA are bad for you, so need a well-ventilated area (prefer fume extraction if possible), if you value your health over time.
PLA doesnt produce anything nasty (as far as I understand), and is supposed to be biodegradeable, due to being made from plants.
I have sucessfully printed things like remote camera mounts to fit to road-sign posts, as well as things like switch cutouts for a Landcruiser dash, Icom UHF handheld radio base brackets, A jig for aligning stamps onto an alloy plate, a bolt protector for a Tikka T3, little potting containers for Mum, Torpedo bottle holders for display, Archery Light mounts, a multi-level pen-holder based on a lazy susan bearing, etc etc etc.
There are heaps of other plastics, but the most common starter is PLA, and people often then migrate onto ABS.
Next question is whether you want one extruder or two.
2 Extruders gives you options for running a second plastic that dissolves, and so you can print much more complex shapes with them.
Single extruder can print support structures, but it does so in the same plastic, and so require more post-print work.
Some types of dual extruder printers can also run in IDEX mode, where each extruder prints a copy of the same item.
My next printer that I hope to buy in the next 6-12 months, will be around the same build volume as the Guider(21L), or slightly less.
It will be dual extruder, both running at least 300 degrees, but prefer 350.
It will be an enclosed chamber with a heated platform that can go up to 120 degrees.
It will have both IDEX and quick-change extruders(to swap out in the event of a jam or blockage).
It will have network, including wi-fi, as well as option for memory card or USB stick.
It will have a camera for watching the print.
It will have the trickery to cancel out the vibrations(increases speed).
Much of this above list the Guider already does, but mine lacks the option of a dual extruder, so some of the really complex projects I'd like to try, will be nigh impossible on a single extruder.
I'd also recommend a UPS to filter the power to the printer as well.
There is an Australian brand made down in Melbourne, but I've heard some mixed stories about them.
I bought some filament from them, and not 100% sure, but it might have been the root cause for buggering the extruder on my Guider last year.
[More to that story, and I cant be sure, but the QC on that filament seems rather varied.]
Anyway, if you have more questions, PM me, and I can tell you more about my experiences, as well give you a list of some of the items I've printed, as well as the ones I've designed, but am yet to print.
