Great statistical work. It’s a small sample size but the data is pretty neat.
CNC kitchen also tested this. https://www.cnckitchen.com/blog/brick-layers-make-3d-prints-stronger
You won’t find this built into any slicer because some assholes patented it and are defending the patent.
It looks like this was testing in tension? I image most of the improvements would happen in shear. Since that’s where you make the crack more tortuous. In tension the increase in contact is very slight.
TLDW;? Will watch it after work, but I’m curious now. 😁
Not as drastic as I had hoped, but it looks like around 5% better layer adhesion provided you increase the flow rate slightly to fit in the gaps. It essentially makes a print that’s more solid in the walls.
I saw elsewhere someone doing prints with transparent filament and they were also getting optically better prints with this.
Also, there’s a pull request on Orca… Not sure when it’ll come out, but they’re working on building it into the slicer.
TL;DW: Small sample size aside, it looks like the brick layers could be marginally stronger in some ways, but it can be weaker if you don’t also increase the extrusion multiplier since offsetting a column of circles down by half a row in a grid of touching circles will make the circles not touch (hopefully that’s an intuitive explanation of the need to increase the extrusion multiplier).
he mentions only vertical offset but I don’t see why it could not be done horizontal if the lines are stop/started at regular intervals. Im guessing it would not be stronger though than a continuous line.
It could, but I don’t think there would be any benefit. The key thing this does is make walls a bit closer to the theoretical perfect solid structure.
ok yeah when he talked about it sorta fitting in between the cracks. so yeah it is closer to more solid. Thanks that actually wraps my head around why better.
