Topic: Recycling "Head & Shoulders" bottles HDPE

I cut a few Head and dandruff bottles with scissors by hand that took me weeks to gather like a few grams, the extrusion worked well (3mm / 150 deg) but very slow like an hour / 1m , because no pressure from the little chunks I believe...  had no luck extruding HDPE pellets

I know HDPE is a $%^^ material to print with, but was just curious to see the results :

I couldn't print or test more because the smell is super horrible, I mean when you heat the plastic you'll breath dandruff and shoulders instead of air, the shampoo odor remains.

But I believe this material can be used, the printed gerbils in picture are 0% infill, so I think for basic geometric shapes with 100% infill I believe this material should it.

Good to see some results. Looks promising. So did the plastic have a smell along with the shampoo, or just the shampoo smell?

Re: Recycling "Head & Shoulders" bottles HDPE

with 100% infill layer to layer adhesion is OK, the rest needs to be worked, don't have too much filament to experiment.
printed at 190 deg, 50 deg bed , no cooling , with Pattex on ground, print is 2,5cm x 1,7cm x 1cm U shape with wholes on sides.
