Hi everyone, first post here, 

Correct me if I'm doing something wrong or I'm posting this in the incorrect space. 

 

First of all I wanna say that I have a 3rd party 3d printer and I use ultimaker cura (4.3) to create the gcode files. The piece I want to print is like a flat rectangular frame with thic bezel (and a big square hole in the middle) and i have to print it upright (touching the bed with the smallest face to clarify) due to print space limitations.

 

Here's my problem, I don't want to use a lot of material and the only support avabile on Cura without plugin (if u can suggest me one I would appreciate) are the tree and the normal one and both start from the bottom of then print plane or fill the whole hole (wasting a lot of material and time). My idea is to create a support starting by the lateral hole faces and with a 45 degree angle get to the upper hole face (to support the print of the topmost bezel). Is that possible to create such a support in Cura? Ask me for more info, maybe i will upload some images later.

 

Thanks in advance for your help.

    You can always design your own supports in CAD, thus as part of the drawing itself. Then you have total freedom of design. When printing in PLA, you could for example design all supports in PLA too, except for a small interface layer of PVA, so you can wash away that and get nice clean undersides in your model. Automatic tools are great for general use, but for very specific cases, it is best to do it yourself I think. The automatics can't know what you have in mind.

     

    See a few examples here:

    This is how you could make custom supports in PLA, and have only a thin PVA-layer inbetween them and the real model, using a dove-tail for good mechanical bonding.

    The pink and orange are custom supports. So I can wiggle them out by grabbing them with pliers, as the model is way too small to get in with a knife. Text caps height is 3.5mm. The added custom brim is to prevent them from falling over. This is for a single-nozzle printer.
