5 months 1 week ago - Commented on Big batch of printer filament for sale - Fire sale price

Closing down our business in the UK (Aberdeen, Scotland) and selling off our machines. We have a year old MCor Iris HD with a stock of some materials (blades etc). Open to sensible offers. info@revolv3d.co.uk.   Also have Projet 4500, 450 and 650, but all require service and repair to be fully operational. Due to condition, happy to accept a suitably low offer.

Hi all,  Wondering if anyone has experimented with alternative paper and glue suppliers and found any that work satisfactorily. We are currently using the suggested Viking Business paper and MCor glue, but at about £60 a bottle delivered, this seems to be a bit of a rip off for the official stuff, when a similar bottle of PVA can be bought for £1 or £2.

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!!!

Hello, I am just wondering if anyone has a 4500 and a 660 and can comment on the reliability of the two? Basically, we are having such problems with the 4500 that we are considering chainging it for a 660. However, we don't want to buy one and find we have been duped again and the 660 is just as bad. Any comments welcome.

Hi, we are also in this position although we have not contacted any legal firms and are at all costs, trying to avoid a dispute. Did your case ever move forward or was the issue resolved in any way?

Hi, we have been using a 4500 since 2014 and have also had similar problems. In fact, the various comments made for interesting reading as we sat and went "yup", "been there", "done that". It seems this machine has several mechanical issues. We have had the same overfill and block the vacuum issue. This seems to have been resolved with a recent firmware which is a bit stricter about entyping the overflows. The failure itself eventually caused the cleaning station to block and welded the head to itself at one point. We suspect this caused the head to be damaged as we have been struggling with alignment ever since. Since then, we have had a bearing go on the fast axis, and regular Clear Binder low failures. And lately, we have had the issue of powder overspilling onto the bed which we have narrowed down to a failed seal on the feeder hopper. We are waiting for that part but in the mean time, we have had yet another problem with the slow axis this time. It seems to hit the cover which moves to allow powder to spill out, but we are not sure why. Basically, we are receiving a very high failure rate and a lot of downtime. I realise this is an older thread, but wondered if you could advise if you have had any resolution or if the printer is behaving better for you now? Also, can you put a figure on the failure rate? Is it in the 50% range or worse?
