Topic: Filament extruder from Heated Compactor?

Imagine a metal box with walls that can be moved inward and heated.

Would it be possible to melt and compact the plastic at the same time into a block.

Then turn the block into a strand?

How would you "turn the block into a strand"?

This wounds more complicated (and expensive) than a granulator + extruder.

Filastruder - the robust, inexpensive filament extruder

Perhaps compress it into a large heated pipe, but use a hydraulic jack to push a plunger sort of like a bench top arbor press...

Re: Filament extruder from Heated Compactor?

There are industrial extruders that use a ram rather than a screw.   The disadvantage is that you can't feed pellets continuously,  you are limited to what fits in the barrel.
