If it is the same type of material i.e. Vera Blue to say Vera Black, all you need do is peel off the round RF tag on the very top of the container and swap it with the other one wanting to use. under the material label you file smaller Metal washer that is the RF tag.
The machine will get fooled in thinking it has the same material.
The only downside to doing this is your part may have a blend of the different colors but if it’s going to be painted or the customer does not mind this will save you that loss of unused grams. I have been doing this for years with no issue or no problems with the print heads.
However you cannot do this when you’re changing to a different material types.
this is when you have to do a complete material flush there’s no way around it.

With the greatest of respect, the machine should be used in the proper fashion. It is an Objet. If you go outside the parameters you have no comeback on your warranty. I have two and they are brilliant. The loss of material can be worked into your pricing and you should allow for it in your calculations. Stacking jobs to run in order of materials is another good way to minimise waste. Changing over too often will obviously result in the loss of more material. Hope this helps, happy printing!
Not at all
what about using a cleaning fluid for parking, and then changing it to new material would it will prevent loss of material?.
There are other print heads from China, that cost a few hundred vs 1k+, I havent seen them but I know they exist.
The rest of the printer, is really easy to maintain and support. Don’t even buy their 4-5k yearly support, just put that money aside, better buy a print head every year, replace a light bulb every 6 months, and you can even replace all the tubing inside, but thats up to you. What I am saying, this thing is really a simple piece of technology. Its just a glamorized InkJet printer with 100+ heads and bunch of tubes.
Keep cleaning this thing and you will get at least 5000 hours before you have to replace a head. The servos last forever but even if they burn, you can replace them with market servos. The printer actually costs a few thousand to make, but sold for 50k+, only because they have patents, which expired this year, actually.
I haven’t tried it yet, but I think its possible to hack their communication mechanism with the printer and completely write a whole new software on top that prints and does better stuff.
Also, since this machine is windows, call your support specialist but before you do that, install a key logger onto the machine. The support specialist will put in their password into the machine, which gives them extra options within the Objet software. Capture that password with the keylogger and there you go, full control!
Oh another, don’t buy those waste containers that cost $10+. I just bought a huge industrial container and extended a tube out of the printer into it, done! Haven’t changed my waste container for over a year.
But at first, i was just taking the waste container and emptied it into the large industrial waste container, kept recycling it. highly recommend it!
