Stratasys material definitely has an expiration. The expiration of opened material is debatable and depends on the environment, but I do know that the foil sealed cartridges are good for over six months.

What is the MFG date on your cartridge?

When was the last time your print tips were changed?

What model machine?

Also, can you recommend a brand and model of 'Clean Station' tank and solution? We don't have one yet. Also, what is the exact model of your machine?
I use a Thermo Scientific W45 like this: http://hylandscientific.com/process-...h-wdl30-heater

I think they might be out of production though. You may want to get an ultrasonic tank anyway which is more efficient for support removal.

Here are some other tanks http://cleanstation-srs.com/

Essentially all the tank does is heat to 70c and circulate the water. So as long as you find a tank that does that you are good to go. The only catch is that it must hold up to the sodium hydroxide over time. Stainless :-) Ebay may have some good deals if you find the right tank.

The chemical is powdered sodium hydroxide. I get mine directly from my Stratasys reseller in a bulk case.

I donate my services to the Tigertrons to make motor mounts, encoder mounts, potentiometer mounts, brackets, spacers, and other similar hardware for the last few years. I even made a whole transmission for display purposes and even scale replicas of the FIRST trophies.

Here is the prototype motor mount for our 2012 practice bot.

There are also a bunch more projects and photos here:

If anyone else has an questions about the Dimension/Stratasys machines I will try to help as I've operated thousands of hours on a 768 BST, 1200es SST, and Fortus 250mc.
