We managed to push our local distributor into getting 3DSystems to replace our machine with their other 3D Printers. Keeping the 4500 is a lost cause.

But 3dsystem is giving credit for another machine? If you can let me know any detail so I can tell a distributor

Not willingly. Took us a couple of months pushing and convincing both our distributor and 3DSystems to replace the machine. We had the machine for about 2,5 years. It broke as soon as it arrived (kept leaking - drips at first), so we had an ongoing problem during the maintenance period and was never resolved well after its maintenance period ended.

So, we kept pushing. At first just to get machine fixed. Then to replace the 4500 with another working 4500. They kept trying to fix the same machine though. Lots of parts changed. Lots of engineer visits. On the 2nd year, even our distributor’s got tired of trying to fix the machine (became even worst than before). They finally agreed to switch the 4500 but they cannot give any additional guarantee (we pushed for financial collateral) that the new 4500 would perform the way that it’s supposed to.

They were willing to do the exact same thing we had like the first machine. If it brakes, they will fix it. Without the additional collateral, we rejected. So, we pushed them to replace with other printers instead.

I don’t know what items you produce with this machine, but if it is possible for you, i would say,

have your 4500 replaced with a Projet 660.I own one and have been printing with it for one year now,

without any major problem. just had to replace 1 flex datacable.

Do you still have ProJet 4500? I have a spare printhead if you are interested in and I am looking for someone with working 4500.
