Hi we have a 660 and It is very riable. Unfortunately we are closing our 3D area for other problems and we would like to sell it. If are you interested in, please let us know.

Bye

The 660 is a good machine. You will get your share of errors so be prepared to learn the in’s and out’s of the machine. The powder machines require regular upkeep and experience pays with this equipment. Lots of benefits once you get it down in speed, volume and color If you do not need color or speed switch to an FDM machine from Stratasys. It’s all application dependent.

Thanks to everyone for the advice, even those who don’t seem to own the printer! It seems we are not alone when it comes to our 4500. We have a range of errors, rarely the same and most seem to be caused by changes of the design between the 660 and 4500. IMHO, it seems the 4500 took a step back, rather than forward. The cleaning station is more basic, positioned badly and fails easily, due to spilled powder. There was a bad error in the original firmware which allowed the machine to overfill itself and block the vacuum. The head is fragile and ours became damaged very early on, unlike the 660 which costs buttons to replace, the 4500 is thousands. We are currently trying to get 3D systems to replace this on warranty, but we may be in for a legal fight on that one. They recently updated the firmware and now we constantly are having Binder Level Low warnings, when clearly there is plenty. This one seems to be model specific and presumably caused by a bug in the firmware. Add in the problems with Blacks and the cost and problems with the powder and I think we are at the point of giving up on the machine. I could go on, but to cut the story short there, the 660 seems the better choice!!!
