From what I see after unboxing it yesterday, this is a great printer. So far I ran tests with a low-poly model, organic sculpture, a mechanical part and a flexible set of parts, in all four it excels. It is all steel so will remain stable for a long time. Very suitable for professional use. The microprocessor is an Arduino mega so very good and easy to program.

A nice surprise is that the printhead has room for up to a triple extruder, which can be developed quite cost-effectively.

Make sure to install stable releases of firmware, also there is software to convert gcode to the proprietary idea (.i) format Wanhao works with.
The Wanhao maker slicer produces great results and will generally have all the settings available you need.

I recommend this machine to everyone.
