I'm guessing a local hardware store or McMaster-Carr should have replacement augers and pipes.

I'm going to consider both approaches and see how that works!

elmoret: when you say "disassemble", do you mean unscrew the pipe from the collar?

Also, if I want to go the route of replacing the auger and pipe entirely, what are the specs of the pipe and the auger?

Thanks!!

Make sure it doesn't get on any other plastic items I.E. wires. As with all chemicals it needs to be done causally. Protective equipment and vented area as it does give off fumes.

The resulting form is generally brittle, and can easily be broken apart and dug out, if it didn't fall out on its own. This is a reliable method for cleaning 3D printer nozzles, given one has the tools to pull it off (most commonly the cleaning cycle of an oven).

The longest I've gotten out of one is ~1500 hours, the shortest about 600 hours. But that is with a sample size of about 5, so it isn't too crazy that one might wear out sooner.

You could try tearing it down and blowtorching, others have reported success with that here on the forum. To swap the barrel you disassemble, heat to ~220C or so using the heater band, then pull the auger out of the barrel (I usually slide pliers between the shaft collar and flange and "lever" it out like that.

I wish the expected lifespan or MTF of the barrel and augur were documented somewhere, that's all.

With the plastic being solidified in the barrel, how do I replace the barrel and auger? Is there documentation or a video for that procedure?

Someone other than me must have had to do that by now tongue

How many hours do you get out of an auger or barrel?

Thanks!

It is certainly 2 years old, but keep in mind it has only run for a total of 320 hours. (8hr/kg*40kg)

This is the same as running for 2 weeks straight.

Are you telling me the expected lifespan of the product is only 320 hours? o_O

Thanks!

I'm saying it may need maintainence parts after that time. For example after 320 hours of running a chainsaw one would be expected to replace the chain.

Here's what the inside of the pipe looks like:

How do I unclog the pipe itself?

Thanks!!

Just my 2 cents.

It is possible there is so much internal wear to the barrel that it can no longer build pressure.

Replacement parts are available by using the contact form on the Filastruder site.

I tried higher temperatures, and I'm at least getting output now, but it's still very very slow, and the texture of the output is rough.

Also, where can I buy replacement fiberglass? I have found it at hardware stores in sheets for like attic insulation, but nothing curved like that which is needed for the filastruder.

Thanks!

I'd also recommend adding the insulation back. It is not only for heat loss, it lengthens the melt zone of the barrel which results in more pressure internally.

Thanks!

How do I test the thermocouple? Is there a test procedure? I have a multimeter.

Thanks!
