Grey areas and can't seem to print?

[natsucielo 0]

Hi, I'm new to Cura and recently while trying to print a chair for my set design, I have encountered some problems. I downloaded the model from grabcad.

1) What is the grey square my model is resting on? Is there any way to get rid of it?

2) Is there a reason why the estimated time to print is this absurd? It is a 4cm chair with quite a bit of detailing, I don't think it should take this short a time to print.

3) It seems that my model is not resting on the plane flat, is there any way to lower the model so there is no gaps between the bottom and the base of the space given in Cura?

Hi @Natsucielo,

Welcome to the community!

What Ultimaker do you have? Depending on what machine you have selected the buildvolume may change.

1) Do you mean the big square? That is part of your 3D model. You can sink it through the bed to avoid 3D printing it. Or you can remove it in a CAD modelling tool.

2) The time is probably not accurate.

With the level of small details I would also suggest to print 2. So both chairs have enough time to cool down before the next layer is build.

3) Yes, in advance you can lower your print in the bed.

You can also under 'rotate', bottom left, choose lay flat.

It will rotate your image so it is flat on the bed.

Good luck!

2.) this absurd print times often results from details in the model that are too small to get printed with the given nozzel-size - have a look at the layer view ...
