Need help choosing a 3d printer

[curious aardvark]

well that was probably a huge mistake fil.
ender 3's are the single most problematical printer around at the moment.
it doesn't help that they use the worst i3 design out there.
It seems like every day we have someone else on here, who's been suckered in by the 3 people in the world who have working ender 3's and make youtube videos.

the cr10s pro - has the same crappy bed design, single central rail, mounted on sideways wheels. basically the bed will never ever be completely level.
However because it uses aluminium extrusion, you can probably mount a couple of side rod and bearing supports. I'd do that.
Actually I'd never buy an i3 with that design in the first place :-)

If you are going to buy an i3 - basically an open framed printer where the bed moves in the x dimension and the printhead in the y & z(or the other way round). Then make sure the bed has rods and bearings on both edges to keep it stable.
One reason I bought the ctc i3 pro b - cheapest printer in the uk, But fundamentally based on a good design.
I bought it to mod and keep the overall cost under ?100. And it's nearly ready for work. I certainly didn't expect it to work as it came. to be fair, it actually did - but once I've finished the mods and sorted the gcode out, it's going to be a really useful workhorse.
But I would never buy an i3 with just the central support for the bed. The larger the print volume, the more hassle you're going to have with it.
I've played with horizontal wheel mounts and they seem stable. but bear in mind that even a 0.1mm wobble - which won't be discernible to the human senses - out at the edges of the bed, can bugger your print up.
And it doesn't matter whether you have auto bed levelling or not, it's going to wobble - so the auto levelling is practically irrelevant.

Back to printing large items for cosplay:- Invest more money.
A good cosplay prop will sell for hundreds of dollars, so look on the printer as a serious investment.
Once you get good at making items for yourself - sell them to other people, you'll recoup your printer cost pretty quickly.
realistically you need a printer with dual printheads. Soluble supports will be your very bestest friend.
The near perfect machine is a formbot t-rex2 - not cheap, but huge build volume, independant dual extruders and a whole host of cool features.

The other thing it's worth looking at - which is Tevo little monster: https://tevo3dprinterstore.com/produ...3d-printer-kit
Very good price, not dual extruders, but large volume and delta print speeds.
tevo's i3's are all based on the central wheel rail design, so I'd avoid them.
