One thing to look out for when printing with flexible filament is bending and jamming between the gear and the hot end.  You might need some tubing or something to guide the filament closely through that gap.

It would be cool to see if you could mix rigid and flexible filament in the same part using a dual extruder.  It would have to be a printer like the Replicator with the extruders on the carriage however.  The flexible filaments apparently don't work well with Bowden extruders.

Based on the operating temp from the website, it should be ok, but we won't know unless someone here purchases and tests it. 

Processing Guidelines:
Recommended extruder temperature: 210 - 230°C

This is why Tim's point is completely valid. What flexible filament? There are many types and the one I thought the OP was talking about was
http://store.makerbot.com/flexible-filament.html <-- that.

Flexible filament in 1.75mm will require slow print speeds, and probably a fan on the extruder to keep the filament cool at the feed portion. A PTFE guide between the feed wheels and the hotend would help too.

A conversion to 3.0mm filament would also help, since stiffness is proportional to diameter^4.

I don't have a problem with noobs asking questions - but at least use full sentences and punctuation, provide links, and show you did even a little legwork. My very first post on these forums was actually helping another user with his Z-tab. Here was my second:

Hello,

I'm having a problem with large prints curling up. I've leveled the bed, and the raft prints great, nice and even, but the print curls off the bed, and worse, curls off itself.

I'm using ABS, at 200deg extruder, 80deg bed. It seems like the extruder hangs out at 190 degrees, not 200.

Tips? The separation mid-print is particularly troublesome. Coming off the bed I can deal with.

Should I run the extruder hotter to get the layers to bond better?

Here's a picture:

A very common problem, but I discussed measures I'd taken up until that point, gave plenty of information, posted a picture. The cure was using an enclosure, but this was before that was common knowledge.

Oh, and I gave advice back as soon as I started learning. All of tapout's 26 posts have been asking for advice.

Are you serious right now?

What flexible material?
Use it how?

EDIT: I should just stick to the Filastruder subforum. sad


The users in the filastruder forums are generally a bit more advanced. I think your expectations might be a bit elevated for the general population but please, don't leave us here with out your knowledge. Your the simon cowell of these forums and some people just need to learn to deal with harsh criticism. I enjoy people lighting into me when I have a lapse in judgement. So please don't retreat to the world of filastruders. We need you here.

As Ian pointed out to me:
As far as the filament is concerned, the new flexible filament has the same properties as U-mold. It melts at a very low 60c.

That means you will need to alter your firmware to allow for the ultra low temps. I have some U-mold at home that I was going to try to run through my filastruder. Not sure how that will work yet.
