Does anyone happen to know the flow rate of the extruder? IOW how many kg per hour of plastic can it extrude if you just let it extrude freely with a large nozzle size and a decent size extrusion motor?

@sigmatero

By searching this forum I was able to find some info. Based on some peoples comments and estimating from the videos the flow rate with the standard screw is about 0.016m3 an hr.

Did you find out anything different?

@rorydickens No, nothing different here. So about 17kg/hr from the 25mm screw. Seems about right from the research I’ve done so far. Not so sure why this is so difficult to get from them.

Based on 0.016 m^3/hr x 1060 kg/m^3 [ABS] = 17 kg/hr.

The person in the Netherlands told me they got one 1.25 meter extrusion 25x25mm in 15 min. that only came out to around 4-5 kilos per hour in my numbers.. Maybe its a engineering issue?

There is also the amount of heat that the heaters can transfer into the plastic on that short of a extruder.

My research into industrial extruders shows them to be quite long and vastly more power.

I would be very interested in a much longer length extruder and more heaters.

Unfortunately in off the shelf parts, I am only able to find concrete masonery bits that long.
