Why do we still use stepper motors? (sopuli.xyz)

Why are 3D printers still stuck on stepper motors? Why haven't we transitioned to servo motors with encoder feedback for positioning?

Is it just too cost prohibitive for the consumer-level? We would be able to print a lot faster and more accurately if we had position feedback on the axes. Instead we just rely blindly on the stepper not skipping any steps when we tell it to move, hoping for the best.

The print as absolute shit though. Literal garbage.

Looks pretty good for the speed to me! This is an experiment. Someone will be able to build on that and make it better.

Speed Benchys mostly are garbage quality.

This is as fast as I've seen for PLA while still retaining good quality. And he probably could go faster with more powerful motors or more of them.

Honestly, there’s going to be a hard peak to how fast a 3D printer can go, because physics. Unless we start running prints in a vacuum and start tuning local gravity….

[–] TwanHE 2 points 10 months ago

There will always be limits to how fast you can go. But as long as the average printer is not even close to whats doable there is room for improvement.

That’s much much nicer. I’ve been looking at the bamboo x1c, its speed and quality is pretty amazing right out the box.

This is mostly a cooling issue. Not being able to solidify the plastic fast enough after it's been deposited.

No shit lol
