Cura placing Brim under model

Recommended Posts

While trying to print a number of models together, I discovered that on some of the models Cura is placing the Brim Under a portion of the model. This has happened twice now.

I loaded four parts onto the print platform and saved the resulting Gcode to an external device. When I ran it on the printer, two of models had what appeared to be the Brim printed under a portion of the print. For these objecdts, there was no brim under the remaining portion of the model. Two other objects had the Brim correctly placed around the perimeter of the object. The misplaced brim was a tight oval, with the proper number of brim lines, under a small portion of the model. The rest of the rest of the model attempted to print correctly, but was essentially printed on-top of the brim in that one location. this resulted in the remaining portion of the model basic starting at layer 2. Starting above the bed, it had adhesion issues and warped so badly that the entire print failed.

Has anybody seen this happen before?

Hi, yes this can occur for at least two reasons:

1 - the bottom of the model isn't flat and so there's a gap underneath - if you move the model down to sink it into the build plate does the brim now go around the outside rather than under the model?

2 - the model is invalid - not much you can do about that apart from fix the model.

I have printed this model before with no issues. Also when I slice the model for my Prusa using Slic3r or the Prusa Control software, I don't get the issue.

Also when I moved the items around on the bed only one of the models had this issue instead of two.

Sorry for the delay, I haven't been able to get back to this. Here is the model in question. I printed the other three parts that were being printed with this (just deleted this model) and did not have the issue. I have not had a chance to go back and print this part by itself to see if it would work. I have printed it in the past with no issue.

    • 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.
