A new approach to multi-colour prints
Have you seen this?
http://hackaday.com/2016/06/20/mosaic-p ... -printing/
It seems they were also running a kickstarter campaign which was successfull and they started shipping out the units:
My first thought is that's a bit pricey as of now...but it looks neat!

Re: A new approach to multi-colour prints
Yes, saw it last year with the kickstarter campaign...
Will be interesting to see how well they manage to synch the filament change with the print.
With 1.75mm filament and a 0.4mm nozzle the ratio is about 1:20, so a 1mm offset in the filament gives 2cm extrusion with the wrong color, and the error margin with a Bowden is definitely higher than that.

Re: A new approach to multi-colour prints
Well, that is untrue.
If you check the how-to-set-up videos you see they're using this with bowden setups and actually they're increasing the lenght of the bowden itself.

Re: A new approach to multi-colour prints
I recall posting about this on the Ultimaker forum a while back. Since it only does 1.75mm, that leaves the Ultimakers out

Well...those who are still using 2.85mm yes.LePaul wrote:I recall posting about this on the Ultimaker forum a while back. Since it only does 1.75mm, that leaves the Ultimakers out
I still find the concept interesting regardless of the filament size.
By checking on the pictures this is using an Ulticontroller, an Arduino Mega, a Ramps 1.4 board, 5 steppers and probably 1 servo.
It's functioning is quite interesting.

As do I, the video on the kick starter is very, very impressive

Re: A new approach to multi-colour prints
The problem I see with this kind of stuff it's that there's little to zero users reviews/videos. For example if you search bcn sigma prints, they exist, but for this stuff? I would love a solution like this, but to jump a expensive boat one needs some users reviews or something.

Re: A new approach to multi-colour prints
I agree, I like to see a lot of reviews that highlight the good, bad and could-be-better points of view on something that expensive too

I haven't made any statement, I just said that precision is important and difficult to achieve with Bowden -- nothing less / nothing more

Re: A new approach to multi-colour prints
So to answer to you I watched the set-up videos.
What they do to compensate that is using what they call the "Scrollwheel" (I wonder if they used this name cause it's just the rotary encoder of a mouse scrollwheel or for some other reason).
This is a small device that they ship together with the main package and is attacched externally before the extruder motor.
They then run a calibration session to measure how much filament your specific printer feeds and that provides sort of an "ad-hoc" calibration.

Re: A new approach to multi-colour prints
Pretty awesome. Would probably consider pre-ordering it I the UM2 was 1.75mm
Don't really feel like converting it as I have tons of 2.85mm filament.

I really like the idea of being able to print a steak, although I suppose the texture will be a little tough.

Re: A new approach to multi-colour prints
You could use NinjaFlex, but if you do use PLA it will biodegrade just like a normal steak, only slower, and without the maggots!
