Hi davidepecchini,

I have purchased and have been using my Wanhao Duplicator 4s for quite some time, it’s a great printer with a metal frame construction, it uses the MK9 Dual extruder, which is a great product. I just looked at their web site www.wanhaousa.com 1 and they now use the MK10 dual extruder. This printer is going for $979.00, over all if you use the correct filament it prints perfect. I have been experimenting with different filaments and they all seem to work but some need more heat and or a cooling fan. The filament I got with my printer works perfect!!! I have not had any issues with my printer except my filament gets stuck, or breaks off in the extruder. A easy way around this is to pull the filament out by heating up the extruder and removing the filament. This way it doesn’t pull it out cold and won’t leave any broken pieces in the extruder head. My only issue with the printer is getting it to print on the bed with out any painters tape and glue stick or rafts. Hope this helps!!

I now use the duplicator 4s having got it after leaving my uni lab having had a Makerbot 2X and its almost identicle but I have to say the 4s seams a much more reliable printer most the time, it works great and I’ve had no issues with it. I’ve only had it 2 weeks it does seam to have a little Z wobble but its an easy fix I will soon upload some parts to eliminate it.
