Here’s the problem with large printers. For those that ask why there aren’t any more large printers out there. This is why, that is pretty much a simple tower scaled to the size my printer can print it would take 66 hours to print. just over 500mm high. I don’t know about you but 3 days is a long time for something to go wrong, any hiccup and you need to either start over or re do it from where it failed. and for that you may as well print it in 2-3 parts anyway. IF you look at the size of the base its under 300mm (only Just) but you can print this in 2 pieces on a 300x300x300 printer, and that’s why I said its the ideal size for a printer in my opinion.
i totally agree with you
Yeah the Eiffel tower is an awesome example of that. I printed one on my smartrap and got lucky because I only had one failure. 14 inches tall at a .3 layer height still took 18 hours all together.
That was sliced at .2 layers and it’s for the 1st printer I built. It prints nicely but realistically if I run it at over 55mm/s it will skip steps so this was sliced at 45mm/s. I have printed a 500mm high 10mm tube at .2mm layers it took 3 hours. The bigger nozzle is also the only way I could potentially justify big prints but the loss of resolution is a concern for me. In the end I have a printer able to print that size if I have to truth is the only time the z axiz got near its max was when I built it to measure how high it goes and then twice to print the 500mm tower to see if it could.
Buy an E3d Volcano nozzle and print at 0.64mm layer height, cutting the print time down to around 21 hours.
@Adam_Steinmark part of the Eiffel tower to me is the detail. I think that .3 was too large of a print height and therefore lost detail. Getting .64mm layers is gonna make it look really rough. But then again there are some people that are ok with that…
@Griffin_Paquette I’m not overly familiar with the geometry of it so I’m partially speculating. It depends on the feature size in my opinion. I think that you could get by with half a mm layer height and still have appreciable detail and not much obvious surface layering on the sloped areas. At this size less resolution is expected from 3D printers but if you insist on printing at 0.2mm layer height it really becomes a torture test for the printer (time-wise). I wouldn’t print that size (even if I could) at that resolution unless I was being paid to.
I have a 300x300x400mm printer and I’ve printed many 30+ hour prints on it. I’ve never had an issue with long prints getting ruined due to the fact that they’re long. I just make sure that I have enough filiment. I would definitely recommend enclosing it to prevent changing room temps from messing with it, I’ve had problems with that on my small printer and I can only imagine how bad it would be for the large one.
Am in need of a printer that can print flayers,stafdnID cards and Cds
Or 7.5 hours on a DLP printer 
(at 100 micron layer height)
I wanted a 12x12x18 printer…when I was done sucking up the envelope, it was closer to 10x10x14…It’s rare I print anything bigger than about 4x4x6.
