Hello everyone. I have come up with an idea in my head for a very simple filament extruder (to make rolls of filament).

I was wondering if anyone here that has tinkered with a Lyman or a varient would know a round about number for the amount of force required to push the pellets through the extruder tip.

Thanks in advance.

Lyman just uses a hunk of lead pushing on top of his pellet hopper and then an auger drill bit.

I don't know how you would determine the pressure required of his design. Looks like it was probably trial and error.

I measured 150-200psi melt pressure when I was designing the Filastruder (www.filastruder.com).

What was your algorithm for determinig the pressur? Just curious.

No algoirthm, direct measurement. Which is why I said measurement. smiling smiley
