Printing PEEK on Ultimaker

Rajil Pahuja is printing PEEK and it looks real good. Other materials also like PEI but PEEK is the most diffiult. Here is a post about it on the UM forum: https://ultimaker.com/en/community/51853-topic-for-printing-ht-filaments-peek-ultem-1010-ultem-9085-ppsu-psu-on-um2 and here is a video of print...

Re: Ultimaker Software News, Cura 3, Cura Connect etc.

I do my own support about 70% of the time. It doesn't matter who designed it but usually I'm the designer. I don't think it's only 1% of people who print their own prints . I guess we all think everyone else is just like ourselves. Which is actually a healthy attitude. I expect it's at least 80% of ...

Re: Super hard nozzles - Test pilots

I agree. I have a few .25mm but haven't sold any. Ruby is good for abrasive materials and those are more likely to clog a .25mm.

So are you working for 3dverkstan now?

Re: Super hard nozzles - Test pilots

Nice! 3dsolex also has multiple sizes of ruby/sapphire nozzles: 0.25 0.4 0.6 0.8 1.2 for both e3dv6 (UMO,UM2) style and for UM3 nozzles. Would that nozzle on the right in the photo above fit in a UM3 core?

I'm not sure .25mm ruby makes sense though.

Re: Block v3 or Olsson Block

No I mean I'm still happy without any modifications at all other than the Olsson block. No iRoberti feeder. But I *did* have the iRoberti feeder on one of my 4 um2 machines for a year and it was great. Now I have the bond tech (I was asked to test it out). The bond tech is still sitting on my most-u...

Re: New heater block to fit standard nozzles on Ultimaker 3

So far I have been able to do cold swapping of nozzles on all my Olsson blocks and all my block V3 changes and all my hardcore changes. At this point I know how much force is "safe" on these (it's about the same force on all of them I think - somewhere around 4-6nM the nozzles break). However doing ...

Re: Block v3 or Olsson Block

I've used both the "Olsson" block from 3dsolex and the V3 block from 3dsolex and I find the Olsson block to be a huge improvement from not having it at all but the block V3 is only a minor improvement. It has better heat transfer but I guess I never push my machine to the limits. I mean I am still h...

Re: New heater block to fit standard nozzles on Ultimaker 3

Very cool modification neotko! I'm surprised the screw on the front of the core doesn't get hit by the internal metal piece inside the UM3 head when you swing the door closed. I didn't think there was room enough for a screw head that big.

>For a 0.8 nozzle it would be just double flow.
4X the flow. But we know what you mean.

Re: Super hard nozzles - Test pilots

Sorry didn't test just the race nozzle change. I did 12 tests. It was a pain changing blocks and feeder systems so I didn't do as many as I wish. I had printing speeds from 7mm^3/sec to 31mm^3/sec depending. Here's probably the 4 most interesting: bondtech feeder, 220C .4mm nozzle: olsson block and ...

Re: Super hard nozzles - Test pilots

The shininess of the block v3 is just for looks. It does not extend internally so it is no harder or slippier inside. Although it can make nozzle cleanup easier I have noticed. Not that I care about that. I'm not going to claim that matchless is any better than olsson blocks but they might be. Some ...

Re: Zero Gravity Direct Drive Extruder

I think this will work with a foehnsturm dual head style solution also as long as the non printing head is parked in a corner adjacent to the corner with the feeder steppers and not in the opposite corner and not in the same corner.

Re: Super hard nozzles - Test pilots

Just to clarify - I think Carl's patent has nothing to do with ruby or sapphire nozzles and instead is related to a newer secret nozzle. But I could be wrong. And it's *that* nozzle, the secret nozzle, that "can't be made in china". Which I translate to meaning, "is unlikely to show up at 1/4 the co...
