Printing the Eiffel tower  

Re: Printing the Eiffel tower

That's a small model that I based mine on: http://shop.prusa3d.com/forum/hall-of-fame-best-3d-prints-f15/photo-for-exhibition-t1506-s10.html#p11702

Prints with very few issues.

Re: Printing the Eiffel tower

Hi Peter!!

Did you base your tower on that 615 mm tall i linked to? just wondering because its not small 🙂 but alot smaller than yours.

Could you please look at the part called EiffelTower-part-E1-repaired if i would be better to place the part upside down with the legs pointing up?

Thanks

Re: Printing the Eiffel tower

I cut that model up and printed to 1600mm (or thereabouts), about 9Kg of filament, so 675mm is small...

Some parts are better printed downside up, E1 is not repaired very well and needs a lot more work. I cut that into about 8 parts (I think). I oriented them so they would print with the least clean-up. Just do what makes sense.

Peter

Re: Printing the Eiffel tower

ok Peter thx for your advice!!

I decided to do a test run on E1, scaled it down to 95% and flipped it up and down, did not touch anything else so i will see how it looks tomorrow.

You mention something about repairing the files, i have never repaired any models and dont really know what to look for so i feel that is something i have read about before i go forward with any complicated projects. Do you have any tips where i could learn some more about this?

Re: Printing the Eiffel tower

ok so now 4h into the print im not sure if my printer is going to be able to handle this!!

all the retractions and rattling is is going to kill my printer 🙂 hmm not sure if i have the guts to see what happens

Re: Printing the Eiffel tower

Why would the retractions "kill your printer"?

As long as there are no faults with the printer, just let it continue. When I printed this, I used 2 printers (Mk1 + Mk2) and it took 2+ weeks of constant retractions and Z Lifts. Yes, it was a little noisy, but this is what the printers are built to print.

E1 is too bit to fit on the Mk2 bed. Cutting it both horizontally and vertically into smaller manageable parts is a really good idea.

You should have NetFabb Basic installed from the driver package. This is an excellent tool to repair models and cut them up. I also uploaded some parts to Tinkercad to manually repair.

Re: Printing the Eiffel tower

Now 15h 65% in to the print some small parts were knocked of by the pinda, it was looking good until now, saw some curling on the tiny beams..

I will start looking into Netfabb, i have the basic version installed so its time i take a look.

Re: Printing the Eiffel tower

Sorry, the other thing I should have mentioned is that you need to print this model very slowly to ensure cooling and prevent curling...

Peter

Re: Printing the Eiffel tower

After about 25h the print was finally done, it looks a little rough but only 3-4 small beams where broken of by the pinda probe or the nozzle. Maybe I can use this part anyway after gluing back the broken parts and some sanding, i will try to post a picture later.

Peter, I was also thinking maybe i have to print this slower, what about slowing the printer down to 80%? what do you think?

Re: Printing the Eiffel tower

80% of what speed?

I know that I set the speed in my slicer, but I cannot remember the figures - it was probably perimeters at around 30mm/sec.

Peter

Re: Printing the Eiffel tower

Ahh, just found my GCode files:

; Perimeter Speed = 22.50
; Loops Speed = 35.00
; Solid Speed = 32.50
; Sparse Speed = 47.50

Peter

I note that I also used relatively slow acceleration rates:

M201 X1000 Y1000 E600 ; set default acceleration

Re: Printing the Eiffel tower

Ok Peter i will try your speed settings as soon my kids are ready with their pangolins and i get my printer back 🙂 What i meant was just to turn down the speed to 80% while printing but i will re-slice and try your settings instead.

Re: Printing the Eiffel tower

and thx again Peter for helping me 🙂

Re: Printing the Eiffel tower

Now my Eiffel tower is ready, please take a look and many thx goes to Peter for helping me out.

Re: Printing the Eiffel tower

Brilliant! Well done.

Peter

Re: Printing the Eiffel tower

Hi there, found the same model. I think it's awesome and a challenge for every 3D printer(owners patience 😉 ). Just got my MK2S Kit and assembled it. Will wait printing this project until the multimaterial Kit arrives (oh so many weeks...) Since i rather want the supportmaterial done wth water soluble material. Will save a lot of work/time i guess.
And whow. the print looks great 😀
Can't wait to print it too.

It prints without support...

Re: Printing the Eiffel tower

Hi Peter,
it prints without support? What about all those overhangs and large horizontal parts?
Can my Prusa printer handle all those parts without support? Would be happy about. Could then start trying his project right away.

See this thread: http://shop.prusa3d.com/forum/hall-of-fame-best-3d-prints-f15/yet-another-exhibition--t5555.html

1.6 metres tall and printed without supports.

Consider the orientation of the model on the bed when slicing.
