Any reccomendations for unclogging the hot end

Not being hip to plastic, what are the properties of polycarbonate?

[jimc]

Polycarbonate is very hard and strong. Its basically a harder version of plexiglass. If you try to break the xt along the layers it wont do it. The break will shoot off in another direction. This shows there is basically no layering and your 3d printed part is basically one piece almost like an injection molded part. The bond on the stuff is truely amazing. Atleast with the black stuff i sampled.

My fishing tackle is all made out of polycarbonate. The raw granules must be blown dry to almost zero moisture
so it does not explode/shoot steam out of the injection mold. Heard 500F was the temp that's made under pressure
in a screw gun that feeds hot plastic in the runners of the tooling.

This is the strongest most durable plastic there is and was developed by GE back in the 1950s as Lexan, or thereabouts.
Fighter jets all use polycarb canopies and it's the bullet proof glass in banks.

My guess is being to print this material reliably is still years down the road for 3D printers. When 300C hot ends
and heater build chambers are more commonplace. Patent on heated chambers will expire.

Drying Temperature 176 to 233°F
Drying Time 2.7 to 5.0 hours
Drying Time, Maximum 6 hours
Maximum moisture 0.020 to 0.043%
Melt point 479 to 529 F into a heated mold at 139 to 189°F

Great for injection molding, by one big pain in neck for us 3d printer model makers.
Moisture is the biggest deal breaker.

I own 3 injection molding tools that make 5 products.
