ALDI email tells me that one of this weeks online specials is this:

I have no experience of 3D printers so any comments regarding this item would be appreciated. Hopefully one of these could be on its way down the chimney in a few weeks time . gift

That is a rebadged Wanhao i3Plus Duplicator & £300 is a competetive price for what it is.

If you have no specific need for a printer & have the time to learn the basics & experiment then it might be a good buy.

In the early days of computers I used to shout out loud to anyone who would listen that EVERY child should have one in the family. I feel exactly the same about 3D printers.

Beware though, there isn't much of a market for good 3d printers with little use & if you find it's not for you then you may be chucking £250 away if you cannot offload it.

So, should one be getting one to make lost PLA patterns for foundry work? With the design being done via Alibre Atom, of course.

I think pattern would be the main use I would have for a printer if I get round to buying. I would only go for lost PLA if the part was shaped such that it could not be pulled from a sand mould.

Good point, and one that eventually crossed my mind later while out in the shed. Maybe next year.

hmm, I have one (Wanhao) and in my view the mechanics are very poor and difficult to retrofix and the firmware not easy to upgrade without a great deal of faff.

That being said it turns out reasonable prints provided you are content to be constrained to 'not quite' engineering plastics.

Secondly, seems rather expensive, so unless you have a burning desire to unload 300 notes do a quick search for Creality Ender 3, should be sub 200 and possibly less (got mine for 160) from a UK supplier. Mechanics much better and upgradeable, but same problems with firmware upgrades. Your expectations need to be along the line of Chinese mini lathes, they will work reasonably well after you have spent some time fettling and retrofitting the junk components with ones that actually work.

If you only want a machine for pattern making then you wont need to print high temperature material like PC and POM so firmware changes not an issue. BTW, I have seen low temp wax filament becoming available if you wanted to use total loss moulding.

I suppose I should have asked already but better late then never. How smelly - or not - are these things when they are running and is the noise - if any - likely to disturb at night as it would be operating in my study next to our bedroom.

I've heard say that ABS can smell & is possibly bad for your health in a small poorly ventilated office.

I'm a heavy smoker & have an industrial sized carbon air freshener rigged up courtesy of our local cannabis farmer.

I'm happy to leave mine overnight but the noise can be as loud as the old dot matrix printers. Mine is also well isolated for vibration which was a bigger problem than noise or smell for us.

The Aldio one has a heated bed which opens the door to PETG and Nylon 6 which certainly are 'engineering' plastics.

As far as I know the Creality doesn't have a heated bed.

(I had the chance of keeping the Dremel printer I reviewed for half price - I decided not to entirely because of the lack of a heated bed and inability to print other than PLA.)

Pla is almost smell-free, noise depends largely on not putting it on a 'drum like' surface. You can also slow down to reduce noise.

I agree that heated bed is a minimum requirement for printing useful materials, Ender3 (and 2) have a heated bed. PETG Hmmm... = quite hard to print well and overly brittle - maybe there is a good variety or I need to persevere.

The problem (as with most budget printers) is the stock crummy hotends cant cope with the temperatures around 250 as the liner starts to distort and caused extruder flow problems (at least it did for me) Considering fitting all metal hotend replacement,

Delighted to be made aware by anyone in the know of a cheap (circa £300) 3d printer that will as supplied go reliably to 300c on the hotend and has a fully configured bootloader already installed so the firmware can be tweaked as required without the risk of bricking the mainboard.

I stand corrected.

I haven't had any issues printing PETG with my prusa i3 clone, and it is less brittle than PLA. Bog standard Mk 8 hot end.
