3D print without some objects

Recommended Posts

I am user of new Ultimaker 3 and Cura 2.5. I decided to buy some objects to print - I want to make the model of Boening Stearman PT-17. The 3D Lab provides STL and GCODE files for Cura 2.3, which does not support Ultimaker 3 printer. Therefore, I cannot import provided settings for older version of Cura to a new one (the error message is – multiextrusion is not supported). I listed/printed the settings file provided with model and I tried to set parameters manually.


I successfully printed some parts of my Stearman, like seats, radial engine, “screws” etc. Now I started to print fuselage I could not solve the problems myself. I tried many times with diffrent settings/profiles. I can print outer and inner walls (I mean – the walls of the fuselage) with line 0.4 mm, but without internal support beams. I can see the support beams on the screen, but as the result of 3d printing the interior of fuselage is empty!

What amazes me is that I see support beams, but my slicer/printer can not print them. I tried to solve problem myself, I spent 3 days and I left a lot of fillament. Could you help?

That lower photo above has walls that are too thin for the printer I think. Try setting "line width" in cura 2.X to a smaller value just to see if that is the issue. If so try the largest possible nozle size where it still prints.

If your resulting nozzle size is smaller than .28mm then I would opt for a smaller nozzle. 3dsolex sells .25mm nozzles for um3. If a line width of .30 makes cura happy (or hopefully larger) then you should be fine with the .4mm nozzle. Consider maybe setting flow rate to 200% or so to compensate. You can experiment during the print in the TUNE menu to see how changing flow rate changes the look of the walls of that cowling (or whatever it is).

      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
