I finally did it... What went wrong... I started to print to small, it does not work. You need to print as big as possible . It is a beautiful model, thanks

There have been rumors of folks completing this project at 95% on the Ultimaker 3 -- if you do so, please share photos!

Also another thought, I have the dual extruder. So for example, any idea how to take the STL file of the fuselage and make it into 2 so you could do the fuselage in white and the windows in black? I'm obviously new to the 3D printing world and just curious as to how you combine 2 different files to line up perfectly to perform this task....

I can't find a smaller nozzle than .4 for my UM3 Ext. Do they make a smaller nozzle?

Tom brookhart, it was designed for the Ultimaker 2 extended was released before the UM3 came out. The UM3 on paper is 5mm shorter than the 2 .. this is because of the new print head is much bigger than before

I have an ultimaker 3 extended and I printed the fuselage at 100% but the wings don't fit until you get it down to 97.2%??? I thought this was made for the ultimaker extended?

@imaginables Yes, so you can either print a few engines at once about an inch apart which would allow the tips to cool enough as it travels to the next one (some stringing may occur) or you could drop the temperature down to 200 or so and set min layer time to 10 seconds. (which sounds crazy but it works and takes forever) Cool head lift has never worked well for me... Also, printing the fan blades at 0.25 nozzle is ideal if not smaller. @youmagine@lamor-selles.de wow. this worked better than I expected.. the engines are too small though I assume?

Hi @valcrow , fantastic model. Thank you for sharing. Been following your instructions closely but Do you have any tips on preventing this blobbing at the tips of the engines? Is it something to do with cool head lift? It was set to 10mm/s min speed http://postimg.org/image/l53f8ki3x/ Thank you in advance

Max has a similar feature in subdividing polys, but like the example with the wing, if you have booleans and creases like the wing does, it may smooth out the main surfaces, but it also tends to mess up the edges. I think the subdivisions need to happen before the booleans, but that also makes the booleans a lot more intensive. I guess its a case of picking your poison. The Engines I agree are a little bit facety, but everything else at the scale we printed it looks pretty smooth. So unless you're scaling it up a lot, it should be pretty smooth for the most part.

I uploaded two examples of what blender can do in my dropbox: https://dl.dropboxusercontent.com/u/10226162/blender_edited_airplane.zip The engine housing uses only subdivision surface which distorts sharp edges while the wing use both subdivision and edge split to keep sharp edges. Hauke made them, he is the expert, in fact we share office at the University :-)

Hej, You can use Blender to smooth the mesh. In this case one can apply two modifier, "Edge Split" to keep sharp edges unaffected and "Subdivision Surface" to smoothen the rest.

@andres Olsson Hey Anders! Thanks for the Kudos, means a lot coming from you :D Unfortunately this doesn't exist in a CAD format, this was done in mesh based software and that's the tessellation level that it was done at unfortunately. And due to it's complex curvature it was difficult to up the amount of polys without breaking other things. While It's fast and organic to make things in Mesh software, you're right in that it shows it's limits here when you start seeing facets.

This is an extraordinary design job, nice work! It is a pity though that you saved the STL-files with such low quality settings as the STL-resolution is now limiting the quality rather than the CAD-model or the printer precision. It would be nice if you re-saved the CAD-files as STL with much higher quality settings, aiming at a file size of like 5-10 times larger that the current files. It appears like that 95% of all models that are uploaded are saved using default settings, which is unfortunate as a simple change of quality settings before saving would make the prints look nicer.

What settings do you recommend to print this plane?

@ Nick S thanks! :D I think scaling it down may not work so well for tolerance on the connections, and the size of the engine blades would be so small that they likely wouldn't register. What I would recommend instead is to print the tail fuselage in 2 halves, and the wings in 2 halves and glue them together but keep the same overall scale. That said I haven't tried scaling it down to UM2 size... maybe you can try and let us know how it goes :D

This looks just brilliant. You have done it again Valcrow. For those of us with the shorter UM2, could you do a smaller version? Or if we scaled it down in Cura would it still work out?
