You may wonder why I didn't consider using aluminum or metal since I have a lathe. Simple reason: I already had the PE laying around which meant I didn't have to spend any money on that.

The real question is why did you use a 3D printer at the beginning instead of the lathe ? Especially in this case where removing material from a blank is particularly adequate ...

@@esakhwaja8592 Yes, it is possible to make 100% infill (no airgaps inside the printed object) on 3D printed objects. There's usually an infill setting where you can specify how much infill the objetc will get. This however drastically increases the printing time if you are using 100% infill.

@Anifco67 If you have a good 3d Printer you just need to turn it on and print the object. There is not that much work involved, he probably just made a 3d Model in like 5mins for that piece and send it directly to the 3d Printer. If it didnt failed it would have been alot less work and cleanup to do. In the video it seemed he made that piece in 5 mins but actually it probably took him more than an hour.

dunno what settings ya used, but if ya try again for fun, id try use prusa slicer and use it to make a moddifier. Copy the part and edit it for a thick spoke wheel like design. export it. take the original put it in prusa slicer. the orginal design is processed as normal with the settings you wish to have the space between the spokes, say like 20% infill or something. right click the original and go to moddifiers load in the spoke design. the spoke design is then put in the exact same place as the original but right click and make it a moddifier, then use the modifier to make it 100% infill or super think walls and 75% infill.

Your videos are excellent and I watch every one of them. I think the three phase AC motor has immense startup torque, as you have mentioned. The two large wheels of the band saw and blade make for a large startup inertial resistance. You have to get all that mass moving and spinning. I think the cross pin is way too short. There is a lot of force on the plastic during spin up. The pin should be longer.

For the 3d printed version, seems like you put in a whole lot of perimeters but had basically the default bottom and top layers. It completely sheered off. I usually try to have the same bottom top thickness than the side wall when I do mechanical parts. Having the model with cutouts with a branch style design would probably have helped distribute the load to the outer portion. Still, your final solution is probably better for long term reliability. 3d printed parts definitely has its limits
@MariusHornberger4 жыл бұрын
Top and bottom layer were 2 layers more than default. For the motor pulley 3D printing is not the optimal choice, but for the wheel pulley I think it's a good solution.
@pascal7894561234 жыл бұрын
Marius Hornberger 3d printing is usually cheap and effortless enough that it’s worth a try. For a 0.4 mm nozzle, I usually print 0.25 layer height, 0.5 mm line width and use double the amount of layers vs perimeters for a equal thickness all around, 1 more for top since the first over the infill kind of doesn’t count. 4 or 5 perimeters with 50% infill is usually my go to settings for those kind of parts and they end up surprisingly sturdy. Good work! Keep it up 👍

I wonder why you are going for almost a 1:1 ratio. Do you also want to achieve higher speed for cutting wood? To make the saw more capable for cutting metal it might have been better to go for a 1:2 ratio that would result in more torque at lower speed. For cutting wood you could then just let the VFD run at 100Hz to achieve the same speed for cutting wood as before.
@MariusHornberger4 жыл бұрын
I aimed for 25 m/s max. cutting speed with the motor still running at 50Hz. And the pulley ratio is almost 1:1 for that
