I am not conviced yet...
The video is not that informative, a lot of laser light, hardly a finished product just out of the printer. The printer itself is not visible..
All the example parts shown are heavily polished or cut afterwards, comparison between a rocket-thing and a bottle-opener???

Leuke calculator. Er zit trouwens in Cura ook een calculator.
Daar kun je in de preferences een bedrag per gewicht of per meter instellen
Ga je niet de mist in met je brons filament? Lijkt me veel te goedkoop omdat het sg veel hoger ligt.

or make them even shorter...

I like the putty knives, they come in different sizes, and you can sharpen them even more, like a razor blade, but then you have a nice handle to hold. Try to get it just under a corner and tilt the blade upwards. Most of the time the object pops off.

could be worse...
someone started a print and walked away, all the pla (5 hours print) got stuck.
Removed it like gadget freak said; heating the nozzle and a soldering iron.

Rhino for Mac! FREE, use it as a beta tester, until it is finished. But I use it for 5 years now…. and for a beginner everything works.
Only thing: no plug-ins yet

by default the 'skirt' is active (and usefull)
if you set the line count for skirt to zero, you can use the whole platform (under expert->expert settings)
But this way you cannot use the skirt or brim….

and of course made some spacers for the limit switches X ,Y and Z to prevent collision. Especially for the Z height to compensate for cookies or so.
when placing an object in Cura, mind that the object will not be printed in the center but more to the right and back. This could probably be edited in the gcode as well.
Here is the gcode, for a chocolate star with cold extrusion:

This is what finally worked; a combination of different ideas and some of my own.
http://www.thingiverse.com/thing:14421
- parts from Joris, some files are old and don't fit any more. The printhead layout changed a lot.
http://www.thingiverse.com/thing:21302/
- from mechadense. But with this setup the winding part broke (lots of force here). But this idea works because the use of spectra line through a bicycle/motorcycle brake tubes instead of thick filament.
I also had to replace the cap of the syringe part by a wooden layered part; the printed one in XT broke...

the 'science' will be the content of the tumbler. I am a goldsmith and we use these tumblers for polishing silver with different metal shapes (pins, balls, satellites) in combination with a soapy liquid. This will get rid of this residue, the water needs to be cleaned regularly. When using liquid, watch out for rust forming, keep the metal under water or dry them thoroughly.
Have not tried this with pla, don't know if the pla gets harmed by the water.
@ CoffeeCup: Colorfabb mentioned that the conductivity is very low because the bronze powder is covered in pla.

Cura geeft alleen de bovenste 10 lagen accuraat weer, die daaronder worden schematisch. Deze routine bevorderd de grafische weergave.
De blauwe lijnen zijn bewegingen van de printkop zonder extrusie, en de verticale blauwe streepjes zijn retractions, en die zitten meestal aan het einde van een actie. Dus om te ontdekken waar een geel vlak begint en eindigt vergt wat puzzelwerk..
-
perfect!
-
attended the Ulti-evening last night with the Colorfabb lecture. They are launching their XT material in different colors in Birmingham.
-
If you do it that way, it is important that your model doesn't vibrate during the movement of the z-stage.
-
I am not from Taulman, I used the from the Kicksterter page to point out that they finally changed their 3mm to 2.85.
I have one of the early spools of 618 nylon with the 3mm, and it gets stuck in the bowden.
-
the nylon can be colored afterwards with die. When the object is thin, this goes really fast, just dip in.
-
Taulman just has a Kickstarter with 6 new products: https://www.kickstarter.com/projects/2144287795/taulman3d-toolbox-of-6-new-materials
there is a flexible one also
" All materials will be available in both 1.75mm and 3mm sizes. The new specification we use for 3mm is actually 2.85mm +/- .1mm rather than 3mm. "
-
you want to use a laser (not a beamer?)
That way you could (?) use the z stage to move the object up and down instead of moving the laser...
-
see here:
the whole setup in a box
-
or use a wide brim and when it starts the second layer, tape over the brim with ductape .
Be careful not to push to hard on the print-bed otherwise your leveling/layerhight will change.
-
I don't understand why you want to put it inside the printer...
The turntable can stand everywhere (no size limit there), the calibration panel is just 2 panels at a 90 degr. angle, so they will stand by themselves and are easy to store. The camera can be on a tripod..
You will have to buy the software anyway.

bring your printer, and get advice

Is it possible to make the line type support, that is already in Cura, like the line style in 13.04? So that the line is a zig-zag?
The point is that with the line support, every line has to start new, and lots of the time the start curls up and has a poor adhesion to the bed. If it was a zig-zag the line would be continuous. The travel from line to line goes in travel speed, so that rips pieces away..
And with removal it was very easy because it is a harmonica; peel one part and the rest follows.
