I recently purchased this CTC 3D printer. It came very well packaged, and within an hour of opening the box, I had my first print going. Since then I have further calibrated the printer, and found that the Yaxis belt needed a little more tension. Now it is printing like a dream. Soon I will be adding a glass build plate to further simplify the printing process and give better results.
The printer itself is a clone of the Makerbot Replicator Dual. Other clones include the Flashforge Creator, and the Wanhao Duplicator 4. I am very impressed with the outofthebox performance of this printer and believe it is at least on par with the Makerbot Replicator I used at school.
