Eiffel Tower

Am having a go at the Eiffel Tower at http://www.thingiverse.com/thing:124990

Printing at 30% with PLA

The shrinkage is making some struts ‘disappear’ and so it has got a bit messy under the first platform - will need a clean up of ‘dropped girders’

But overall I’ve pleased with what I’ve got so far….

I suspect PLA is better material to print it than ABS. My first attempts to print something similar with ABS ended up in disaster as ABS shrinks a lot and then those curved sides tend to straighten up making them taller than supposed and head then starts catching them up causing missed layers, printing in air/dislodging ‘towers’, etc. To fix it I was heavily tinkering with gcode adding additional paths and approaches to towers from ‘correct’ side…

I am glad to see your sides eventually met and formed proper structure.

Here’s what I have noticed which I think does contribute to printing in air not “making it”
Whenever AM starts to print a layer it doesn’t print the outer edge first - it prints the layer just inside the outer edge first and then goes back to do the outer edge - if the supporting material is marginal - i.e. four tiny posts (i.e. leg of a tower) the first run around (one layer in from the edge) misses on two out of the four posts and droops - then the second run around (the very outer edge) and that completes OK

I’ve noticed this on ALL prints recently - not a problem unless your supporting material is very small as was the case with this print

Anyway here is the finished bottom third - all in all not bad

I would just like to say that it is not AM directly but Cura (I am sure that Slic3r would do something similar). You can see it with previewing gcode.

[Steve N @discosteve My Robox is a Blue Commercial Version]

I agree its Cura not AM - the scaling shrinks some parts to the point where Cura doesn’t bother generating GCode for it - anyway here’s the finished article, some gaps and the tower top got lost in a blue stringly splodge - this was at 30% scale - I’m reprinting in my new Yellow PLA at 50% now to see if it will include all the cross struts

@discosteve do use some kind of gcode preview to see it before you print it. If you are interested (and brave enough) I can pass you a patch for integrated gcode-preview that works with the latest AM (as in here).

[Steve N @discosteve My Robox is a Blue Commercial Version]

@clicky I may take you up on that - not sure I want to be messing around too much with AM internals but as the GCODE files just sit in the cache folder is there a standalong GCODE viewer anyway - love the video on that thread linked BTW

So this is a nice online 3D viewer

Mine is definitively nicer! :p And optimised for Robox gcode (or at least was before) knowing about 0.3 and 0.8 nozzle…

I might need to deploy it somewhere online as well (it can run as standalone app on desktop, HTML5 web page or even android app!). It just requires some time to provide proper deployments for them… eh - where to find another 10 hours a day?

Anyway - even simple http://gcode.ws/ would give yo some indications of printing in the air in you carefully go from one layer to another…

[Steve N @discosteve My Robox is a Blue Commercial Version]

Yes I do like gcode.ws but there’s no 3D view (that I can find)

I have my own domain and webspace (somewhat of a dustbin at the mo mind) if you need a web home @clicky

I’m pretty sure I have answered this already once, but that reply might have ended up in spam again. Anyway - thanks for the offer - I’ll keep it in mind. It is mostly finding time to crack now to nicely load gcode over the net in JavaScript and integrate it with GWT. Drag and drop of file would perfectly do as well…
