I plopped $320, printed a few things to improve it, and added about $7 in misc ****, and print at 150. The authentic prusas are way overpriced IMO.

Kinda nerdy, but we should do a print comparison. All these machines, same test part, print time limits- compare quality.

It depends on what you are printing. If you want to do higher temp plastics that need a heated chamber then the prussia is going to be poor platform to start with. If you are printing PLA and the occasional ABS part then no biggie.

My print visual quality is just ok. Where my current printer shines is that it can make a dovetail shaped piece and cover the board with it and all of them will be within +/- 2 thou of each other measured across gage pins.

They don't skimp on components though.

I have a re-branded WanHao i3 V2.1 clone and many of the components had to be replaced or modified in some way because they "cheaped-out".

The fact that wiring to the build plate on the motherboard connector burns out easily because the wires can't handle the amperage required is a classic example of how crap some Chinese products are (see https://3dprinterwiki.info/heatbed-t...-mosfet-board/.)

So far I've added an external MOSFET to handle the above problem, added a glass plate because the build plate is now warped, added a Swiss hot-end and re-wired the heating element because the OEM wiring was too fragile.

Haven't been able to use it for weeks now because I can no longer level the build plate because the tray that the build plate mounts to (via screws and springs to control the bed levelling) keeps bending at the corners - it's way too thin aluminium so I can't tighten the offending corners.

I've ordered a more-robust lower plate but also the new Prusa Mk3 - there's so many useful things to make with a 3D printer and mine was running continuously while I was at home and I'm sick of having to deal with the ongoing issues of the WanHao printer

The mk3 looks amazing. Multiple extruder, easy eject built plate, faster, etc.

Cheap CR10, few essential mods, pretty happy with it so far. Not great, but decent for what it is. For geeking out, here's what has been keeping me (amongst a fairly big team) busy designing, building and testing the best part of the past 3 years:

TLDR; blown powder, laser-based deposition, 11 degrees of freedom, 4000x1500x750 mm build chamber
