Topic: Is It Possible to print solid and honeycomb on same layer???

First off..Hello All.
I am using a Da Vinci Junior.
What I am trying to accomplish is:
To print a part that has 4 locations where it can be drilled so a screw may attach it to another piece.

I would like to set the print style to honeycomb or rectilinear and have the (4) areas to be drilled be solid. This would obviously be to save filament and also to keep the weight down on the part.
Is this possible?

For example: Imagine a Circle that is 1/2" high x 1/2" wide with (4) quadrants having a 1/2" x 1/2" solid area for drilling .

Thanks,
Metal

Would increasing the perimeters work? Then you can design the drill holes into the part, even a bit smaller if you still want to drill them out, and the increased perimeters should help keep the drilled hole strong. Should save a tiny bit of filament too.

Or you could just design the areas to be drilled into the psrt and even print starter or correct size holes in those areas.

Not sure if this would work as I wanted to print at 10% honeycomb. So if i increased the perimeter I would still have a somewhat hollow area where the screws would need to go. If I use rectilinear then I have a potential spitting of the part due to the overlapping design.  You would think there would be a way to print both honeycomb and solid on same layers.

I did try a test run with the holes already printed so that I could use a screw. The downside is that the wall thickness of the hole is to thin and I do not see a way to change that. So the screw (Not a bolt) actually cuts thru the wall of the hole. It works kinda, but isn't as strong as i would like it to be.

Aside from creating an AMF file with slic3r, I can't really think of a way to do this. Sorry!

Out of curiosity, I tried using two seperate STL files, one for the 1/2in circle and one for the solid holes(lol), and changed the object settings for each and it worked! If you use slic3r and want me to do a quick write up I can, just say please! big_smile

Increase your perimeter count and put pilot/complete holes in the design. I do this with my non-solid prints that need to be mounted, at 5 perimeters (0.4mm nozzle), and the screws I use have plenty of material to dig into.
Also, if you want a "perfect fit" and are using machine screws, invest in a good tap and die set. Much easier and more permanent than forcing the screws to cut their own threads.

You increase your wall thickness by increasing your perimeter layers in your slicer. However if your physical design limits it, there can only be X amount of perimeters in a given space base on your wall thickness divided by extrusion width. If the design allows it just increase the size of the area around the screws. This may require enlarging the external dimensions of your part if  you can to allow room internally for the expanded screw area.
