Scalable 3D Printer
One big challenge with scaling anything up (or down), is that not all properties or characteristics scale linearly.
Consider a trivial case: a small cube. If you double the size, you've quadrupled ...

Determining the temps and speeds for DIY printers?
The short answer is, you use the temps and speeds that give you good results. It's trial and error.
The temperature number your printer reports really doesn't matter. That's just a process control ...

How fast can printer head move without damaging steppers?
Short answer no
We use stepper drivers to limit the current, the travel speed is at capped by the amount of current supplied by the stepper drivers. This prevents the stepper motors from damaging ...

How to obtain high resolution prints in a shorter period of time?
You could experiment with slicing. For example, you might not need high resolution all over the object, but you can speed up some straight parts by using greater layer high there. See a part of Slic3r ...

What exactly is the relationship between Flow/Feed Rate and (Print) Speed?
By turning the knob in the main screen, you're adjusting "feed rate".
This is essentially a factor that all g-code speed settings are multiplied with - "speed dial" seems an appropriate name for it.

How fast can printer head move without damaging steppers?
What would my printer do if I set very big travel speed?
If a speed is set above the limits of the stepper, the stepper will stop rotating or stutters.
Basically there are 2 limits, the first is ...

How to 3D print an object with variable printing speed?
As @fred_dot_u mentions, Simplify3D has the capability to do this, but you can achieve the same effect by slicing the file twice, once at 40 mm/s and once at 50 mm/s, and then manually combining the ...

Monoprice Select IIIP Plus - Best speed settings and speeding up prints
In my experience a print speed of 50-70mm/s is ideal. Even if you set the speed to 150mm/s the print head still changes directions often and rarely will have enough time to accelerate from 0->150 ...

How to print a cylinder with hundreds of small holes?
That's a hell of a print!
You are printing a model that has a highly complex structure there, with about 650ish holes, assuming there is space for about 2 perimeters between each hole.

Nozzle moves very slowly from home to start position
I had the same problem, and I solved it by changing the Z-Axis Feed Rate to a much higher value (1000 mm/min.) in Repetier Host via Config -> Printer Settings -> Printer.

Improving print speed by adding holes
Holes in vertical walls will make it take significantly more time to print, not less. Rather than being able to make a continuous path around the box on each layer, keeping the print head at the ...

Is there a slicer that can set the print speed for each layer as a function of the layer area?

Ender 3 seemingly speeds up too much on straight long shell lines
