Re: UM2 print head project

Guys, sorry for being so emotional about the drawings but it was really horrible to take apart my UMO to just crosscheck the dimensions... Anyway - I agree that open all manufacturing details would be a headshot as it would make it much more easy to copy/clone. So I think I will start porting the s...

Re: Teaser for the New Ultimaker....here we go!

zoom in... https://ultimaker.com/src/image/teaser/111016.jpg the part that rests on the ground is bent... the surface quality seems suffering some kind of vibration.... the internal side is not visible and ... it looks pretty good, if you look at it for 1 second... but it's not so impressive as some...

Re: Filamet copper

I am thinking this filament, if it conducts electricity well, would be interesting for printing electronic circuits in 3D inside a non conductive polymer. That assumes one would get across a properly working dual printer of course and it would be most suitable for small scale production, but it is ...

Re: Filamet copper

... I don't think so... huge potential??? PCB etching is faster, more precise and reliable process (even in a DIY process).. and it is much cheaper! You should try for yourself making a PCB at home you can reach result as this one (prototype of amplifier for a pressure sensor) https://plus.google.c...

Re: PTFE coupler - Theory and practical details

Your block appears to have little to none chamfer. The early ones had an additional chamfer where the thread starts, which some said would have a negative effect on the lifetime of the spacer, so that chamfer was removed. Yes, both original block shipped with UM2 are without any chamfer, the change...

Re: Nozzle Temperature

You equipments seem to be ok but as Anders pointed out a bit, there are a lot of effects to be considered and whenever possible to be excluded. On the long-term equilibrium state heat conductance through the sensor certainly plays a role. However, the biggest influence I see with measuring at diffe...

Re: Nozzle cloggs BETWEEN two prints???

You can take out the nozzle and inspect the hole with the phone camera. Also if it's deformed I fixed mines with a 2mm drill bit. 3.2mm drill bits exist but I suppose they are more expensive and I'm not sure if the olsson it's 3.2 or 3.15 Hi, I don't know what you mean for expensive... but just for...

Re: Filamet copper

So, we'd need a way to get that plastic out after printing a complex and sensitive net of PCB traces without moving these traces by as much as 0.3 mm (that requires around 0.5 mm copper-copper spacing which is huge compared to the 0.15 mm standard). Maybe print the traces onto a heat resistant mate...

Hi Drayson,
Yes, it's true! They are almost completely useless !
And it is shameful that a device marketed as Open-source in reality it is not at all! :-(

Re: PTFE coupler - Theory and practical details

I wish to share my thought about the deformation of the spacer... So, have you ever noticed the shape where the spacer get in contact with the hot side of the integrated nozzle? https://plus.google.com/115298954657177960462/posts/RNiVDhosKZJ This could be the reason why the spacer begin to deform a...

Re: Anyone purchase the Advanced 3D printing kit?

with ABS having a frontal door is quite usefull (above all if the ambient where is collocated the printer is suffering from air currents) but it must be possible to open on a side when you print big model or the air moved from the little rear vent will bounce back to the model bringing it to detachm...

Re: UM2 print head project

I will invite you to do some calculation about the linear expansion of a filament of PLA ... http://www.engineeringtoolbox.com/linear-expansion-coefficients-d_95.html Linear expansion is pure thermal expansion -- that is what happens to the filament when it gets hotter, and I agree it is not signif...

Re: UM2 print head project

Hi Neotko! Still don't understand your explanation... Seem that you talk about "heat" (caused by IR irradiation) like if it was a fluid... really this doesn't make sense for me ... The problem is the following: when you retract you bring hot filament higher in the head. If you just retrac...

Hi all Hi Neotko It's been a long time ! I was busy on other project This may be why it worked for me :roll: , because I always tested PBI with the Bondtech feeder from the beginning, never with the UM origin one. Anyway my PBI print head still works fine without any problems yet. Neotko ,   for PB...

Re: UM2 print head project

0.2 layer height 210 - 215 & 225 C. The heat crawls up on each retraction moving the heat up, is a well know effect and the cause of real clogs while using Wood filaments, wood filament moves the heat really fast (because is a filament that is very easy to 'heat' fast) then with each retraction...
