Welcome, prints look good for that size. High detail at this scale is usually not practical(very long print time) so I’m curious to know, what size nozzles and layer height are you guys printing in?

NASA is right up my alley! I have been playing with this Saturn V model. That Woolly Mammoth model is amazing, that would be impressive.
Thank you for all of the help!

Well we are very new to the 3D printing world so we are learning very quickly how much “time” plays a factor. I have been using a 1,0mm nozzle with a layer thickness of 0.5mm a extrusion width of 0.8mm and a skin thickness of 1.6mm . I use the 0.5mm for smaller objects with the settings set to layer thickness of 0.25mm a extrusion width of 0.5mm and a skin thickness of 1mm. I am open to any suggestions as far as settings.

Well to be honest im not sure how this machine differs from the standard printers, this is the first 3D printer we have used, I can say that the set-up and training on this machine was far simpler than I thought.

Thank you for the links, that is a very interesting concept. It would be nice to see NASA release a 3D model of the solar system with all of the data they have collected over the years. Printing the surface textures of different planets would be pretty cool.
I think your best bet is to stick with that setup if you intend on taking advantage of the full dimensions. The big nozzles and thick layers might limit detail/resolution but with geometric designs(like the beautiful crystal you printed) dimensional accuracy is still perfect and should yield great prints. I use .1mm nozzles with .1mm layers on my smaller printer if I need high detail but using that set up on anything larger than a few cm^3 starts to get ludicrous. My largest printer is 25.4cm X 25.4cm X 26.0cm. Use anywhere up to .8mm nozzle on one extruder for infill/support any anywhere from .2-.5mm on the other. I have considered putting together a large format (looks like so much fun) but I haven’t had the need that would justify. Good luck and enjoy!

For practical purpose large format printers usually have much larger nozzles and run with thicker layers (unless you want to spend days or more on a print). So it’s literately like zooming in on the model. For example, using a 1.0mm nozzle means any detail in the x/y axis smaller than 1.0mm is not possible without putting a smaller nozzle and therefor drastically increasing print time(resolution in z axis depends on layer height). While small detail isn’t possible this shouldn’t have any effect on dimensional accuracy or quality of prints that don’t involve tiny detail. This also means there is little room for error because small imperfections are also “zoomed in”. A hiccup on a print with .1mm layers can easily go unnoticed without a magnifying glass but with the large format any imperfection is going to be much more noticeable. Looks like these guys have it dialed in pretty good!

I have been playing with speed vs detail for a few days now(that crystal took 16 hours) with , with the dragon currently printing the time lost seems really to be in the supports. We are printing him completely hollow at about 38" long and the support structure its generated is a bit excessive. I am trying to get the support settings right so that I can shave hours off my print times. The large format is fun and surprisingly simple to work with!
Thank you for all of the help. Ill be sure to continue posting our creations.

Maybe you can be the first to print Pluto? Does anyone know if those height maps already available to the public?
+1 on the finished big Marvin

That would be amazing! I would love that. Let me know if the height maps are available. We are planning on printing a scale model of the Eiffel Tower at 80" high!

Congratulations on your new purchase. I am the US reseller of BigRep GmbH.
Contact me if you need anything.
Thank you.
Wow that’s awesome! You could collaborate with the guys (@Tiesdenh ) next to 3D hubs that are trying to make the kids bike from 3D printing. You could almost print the entire bike in one!
