Hi, newbie here. I have been having trouble printing flat surfaces on an angle (45 deg). From the cube pictures, it's a cube with 2mm wall thickness, you can see that the cube deformed a bit at the bottom and a few layers got bent. Similar thing happened when I tried to print a small spur gear on an angle. The bottom part is also deformed. What could cause this? Not enough support? exposure time?
Also, if anyone has experience printing spur and bevel gears, what's the best way to orientate and support it without impacting the teeth. My gears has module=0.5, pretty small LOL.
I am using the monocure rapid grey, printed at 8s exposure and 50um layer height.
Thanks!!

Put one thick support right on that bottom corner then smaller ones up the edges

From what I’ve heard, you really don’t want to make gears without resin.

Yeah there’s people saying that and I don’t know why. I’ve had great success with both gears and threads

I think the main reason is probably because resin is brittle, hence bad for gear application. But I think it's good enough for prototype purpose, and add some flex resin would help with durability I think.

Yeah...you gotta use the right stuff...I use Siraya abs mixed with tenacious
