Supplier recommended same temperature as last material processed, so 230C was probably a little hot.

Its also probably not a good idea to run with a melt filter nozzle, better to run with a non melt filter nozzle or no nozzle at all, so there isn't a screen that can get plugged up.

Other than that, its a pretty standard purge material that gets used a lot in industry.

Thanks for trying it out, and for posting it here. I'm following up with the supplier/manufacturer to get more details on this and/or recommendations. It is possible that 230C is too hot, and that there is too much fiber content to use with melt filter nozzles. I'll follow up here when I get more info about heart bingo casino, and in the meantime I've pulled it off the site.

Any update?

Purgepro 1000 - Not recommended.

So, I finished up some Irogan A85 recently, and still need to write up the review, but I got it to extrude and print with pretty good results with photos so I just have to write it.

I decided to switch to some EL700 last night, and thought this would be a good time to try the Purgepro 1000. I heated it up to the ~150C I was extruding the Irogan A85 at, put some Purgepro 1000 in, and waited until nothing was being extruded anymore. I thought that meant the Purgepro had purged the Irogan A85 - at which point all that is in there was high temp Purgepro being moved around at the end of the pipe (I thought). I upped the temperature to the one required for EL700, 230C, and added EL700. Then - an odd thing happened - nothing came out. The pellets were being crushed, the motor was turning, but nothing was coming out. I turned it all off, removed the insulation, removed the thermocouple, got a wrench, started to unscrew the nozzle and BOOM - the nozzle shot out across the room with a plume of smoke behind it. Then a big cloud of smoke came out of the barrel to envelop me - I got out of there trying not to breathe any of it, but it did knock me down a few pegs.

Later I found the nozzle, and it is really really clogged, all the way down through - the Purgepro apparently has something in it that doesn't quite melt, a stringy material mixed with a very sticky material. It's like a mixture of long hair and solid glue. What happened is the Purgepro instead of pushing the Irogan out, it clogged the nozzle (so when I thought it had emptied the barrel of Irogan, it actually had just plugged it up and trapped the Irogan in), then when I added the EL700 that melted and plugged the Filastruder further up. The Irogan decomposed into various gases that built up between the Purgepro blockage and the EL700, and shot the nozzle off the moment it was loosened.
