Desperately seeking ideas re: large build-area, cheapish 2nd 3D printer

It's come to my attention that my excellent Flashforge is not cutting it in the legs department. The build area is just too small for legs and other larger projects I'm contemplating. 

I don't want to spend mega-bucks on a second printer at this stage.  

Can anyone please suggest/warn about any 3D printers they've used with large build areas? I would like a fairly reliable one with a build area around 280mm/300mm cubed or larger. Preferably with a heated build plate. One extruder is okay.

A kit one would be okay, provided it arrives with all the parts.

P.S. I won't hold you responsible for future print failures.

Have you thought of building your own design?

Start with a RAMPs controller, parts are readily available from Ebay.

You can make it as big as you need that way.

I think CR-10 is one of the best low cost large printers today.

You can get it in sizes from 300*300*400 up to 500*500*500.

Much easier and faster than to source and build one yourself.

Re: the Creality.

That one looks interesting, Mats.  It looks like I would be paying a minimum of 800 Aussie dollars for that one, even on ebay from Hong Kong.  That's still pretty cheap for such a large build volume. The youtube reviews seem pretty favourable. Do you have one of these or know if any MRL people have one?  

Are you familiar with that software which was mentioned?  Do you think it would it be difficult to source and set up the software? 

Going from the video I would have to enclose it somehow to print ABS. 

Worth looking into.

The software that is used is Repetier / Cura ( Slicing software ). That's the software that I use for both my 3D printers. It looks like they use a modified version of Marlin ( for the hardware ).

It's a software combination that I have used for more than 2 years. 

The printer comes with an SD card with the software, or you can download the latest version from

I setup both Marlin and Repetier when I built my own 3D printer. I found very good guides, so that was never an issue.

I took the plunge

Mats, I took your advice and just ordered the 500x500x500 CR-10 from ebay for $1,143 AUD (about 763 Euros or $906 USD).  I'm crossing my fingers it's not a dodgy knock-off and that the bed is heated.  

I'll build some kind of simple cube to cover it for printing ABS. With that size I won't ever be able to complain about build area. I could even print the cube parts in the printer, I suppose. 

Now to wait 3 weeks to a month for it to arrive. 

Thanks for your prompt advice, guys.

I wouldn't know how to build

Thanks for that suggestion, Ray. I wouldn't know how to build one from scratch. I've got too many other projects going at the moment to research how to go about it.  Good suggestion, though. Maybe one day in the future.  

I think I'd rather get a pre-built one or a very straight-forward kit at this stage.

Update on the CR-10 (500*500*500 size)

I thought I'd provide an update and a bit of a review on the 3D printer formerly known as the 'Creality CR-10' but now known as 'The Monster that ate my work-room'. 

There was an initial no worky involving the ebay seller having to send me a new power-supply which I had to replace.  It's now fully worky and is producing very nice quality PLA prints.  As an act of loyalty, it was christened by first printing the myrobotlab keychain. Thanks, Alessandruino!  It turned out perfectly. 

In my haste to obtain the largest build volume known to man I failed to consider that, in order to print ABS, I would have to find a way to enclose this beast.  This is particularly an issue with this size as the glass bed moves a LONG way back and forward if you are making a very large print. I'd be looking at about 1040mm long for clearance (sheesh!).  I'm tempted to print some large square plates and slot them into some aluminium extrusion with printed corner brackets as a cheap and lightweight alternative to making a perspex enclosure.

It arrived with a glass bed which was nice as I prefer printing on glass. However, using the edge of a long ruler, I noticed the centre of the glass was concave by at least a millimetre. This is a problem given that a lot of printing is done in the middle but when the extruder on this model moves to the 'home' position it moves to the front left corner. This could cause a glass damage risk if it was levelled in the centre area which you would have to do. I found the other side of the glass was almost perfectly level so I just had to turn it over.  Happy days.  Youtube reviews seem to suggest this is a common issue. 

It has four screws for levelling which makes it pretty easy.  I've never been able to get my head around why so many printers have three when all the squares and rectangles I've come across have four corners.

The only other criticism I have is that some of the cables are too short, severely limiting where you can place the control unit. I've heard this complaint even in relation to the smaller models.

It does take a while to heat up and the bed heats up completely before it starts heating the extruder. Weird.  

The thing is practically silent. I was surprised at how much quieter it is than the Flashforge Creator Pro, even with it's door closed. 

I'm using Cura, which I down-loaded from the web-site, as the version provided with the SD was ancient.  

I recommend leaving the broken-English instructions, provided on the SD, to the angels and relying on youtube instead.

I'll update this review when I've tried it out with other filaments but, all-in-all, I'm a happy camper. Thanks, Mats, for the suggestion.

I'm so happy to hear that you got it worky and that the PSU problem got sorted out.

I think the printer is heating up the printbed first to avoid melted plastic to flow from the nozzle before it prints. 

The reasons that many printers use only three leveling screws is that you don't need more. With four screws you may bend the printbed, and that can be really bad if you have a printbed made of glass. It might transform into 1000's of pieces if foreced to bend.

If you have a chair with 3 legs, it will be stable even if you put it on a bumpy surface. But with four legs it will not be stable unless all four legs are on the ground.
