Postprocessing prints: Support removal, sanding, polishing, smoothing. Chemicals, tumblers, etc.

It was good to hear some of the solid reasoning behind the colorfabb material choices. For some time now, I have been hoping for a PLA/ABS hybrid (combining low-shrinkage from PLA with smoothability from ABS) but now I know why it won't come from Colorfabb (styrenes are baaad). I'm looking forward to using more metal-fill filaments. Bronzefill really made me "fall in love" with my printer all over again. If I could suggest something to set Colorfabb apart from many (if not all) other filament producers, it would be a line of colored matte (non-glossy) filaments. High gloss accentuates surface imperfections, and hopefully a non-glossy surface would be sandable.

@ultibrain, I would love to catch a ride. How late will you be at S'dam central?

Aw, snap... I'm not going to be able make it :-(

One idea for more "interactive"/workshop-like activities during the event is postprocessing prints. Polishing bronzefill, sanding PLA/PHA etc. Also it might be a good idea to bring lots of reinforced teflon parts, because Colorfabb is going to release new (non-transparent, colored) XT filaments that print at the same high temperature. I'll have two of those parts please... Daid, did you finish the cookies you got last time yet?

At the ulti-evening I tried freezing my buildplate to make the nutella less droopy once printed. Should have used liquid nitrogen: http://3dprint.com/9148/3d-printed-ice-cream/

I would think that dipping chocolate for icecream could make for a quick setting material. You know, the type that instantly hardens when you poor it over icecream. I found a recipe that refers to it as "Magic Shell": http://www.thekitchn.com/make-chocolate-magic-shell-ice-cream-topping-with-only-2-ingredients-171745 Yesterday I tried if we could make the nutella a bit less runny by placing the buildplate in a freezer for an hour or so. This did not really work (the perspex material did not seem to have a high heat capacity and warmed back up rather quick), but I think there is merrit in a chilled buildplate for pasteprinting. A "frozen" slab of aluminum would have worked better.

Thanks for a nice evening, and thanks for the inspiration Joris!

Awesome. I backed the Discov3ry paste extruder, but decided I wanted to build one of my own. I'll try to make it over.

(my edit)

No, pretty sure they are "new batch" (production dates april 5th and may 2nd 2014). Here's a timelapse of it printing (245°C at 40mm/s, no heated bed, blue tape): http://instagram.com/p/pQscQRRY1h/

Strange, both rolls of XT I have printed with print fine without a heated bed on my UM original at 245 degrees. I just need to make sure the first layer is printed really close to the printbed (pressed into the blue tape).

AFAIK, Octoprint does not display (or know) the filament diameter. I guess where it says "Filament: 1.93m", it is telling you it will use 1.93 meter of filament. The number you can fill in on the Control tab is only for manual extrusion (and it is not a speed, but a length). Octoprint basically copies the gcode file directly to the printer, without altering it. If it prints directly from Cura (over USB), it should also print with Octoprint (over USB).
