Cura doesn't show all print area

Recommended Posts

Hi everyone, I’m new with 3D printing and I’m having some issues with Cura. Basically, when I open an STL file and I chose the layers view, some part of my object doesn’t appear… and when I sent to print, it didn’t print that area.

I tried to rescale the object and when I did it, the Cura was able to show all the object area, so I think that the problem is the object size… but that doesn’t make sense because the size of the object is smaller than the print size limit.

Someone can help me here please?

Thanks,

Joana

Some of your walls are too thin to print. Cura doesn't like to print thinner than 2xnozzle width so about .8mm. Due to floating point errors it's safest to make all your walls at least 1mm wide.

If you want a quick and dirty solution you can lower your nozzle a bit *and* lower your shell size to be an integer ratio of that. .4mm is standard nozzle. So for example you could enter .35mm nozzle and .7mm shell and your part might come out in layer view. If so you can increase to .36 .37 .38 and so on until you have the thickest possible. The printer will print okay at .35mm (even though it's a .4mm nozzle). It will put the lines .35mm apart in the infill instead of .4mm and it will underextrude the proper amount. But the quality will suffer a little bit. Going down below .3mm will be pretty bad quality - still maybe good enough for you.

If you created the model it would be better to just make all the vertical walls at least 1mm.

By the way - always trust layer view - it's what you get. If it doesn't look right don't "hope for the best" and go ahead and print, lol. And always check layer view as it reminds you things you forgot such as "oh - crap - I forgot brim" or "oops - infill is wrong" or "oops - those overhangs will be tough".

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
