I’m going to accumulate my experiences with printing with polycarbonate here.

I have a Flashforge Inventor dual nozzle printer. I’m using Simplify3D as my slicer. I have recently purchased Gizmodorks (www.gizmodorks.com) transparent polycarbonate filament (1.75 mm).

My goal is to print a box with a transparent window.

Simplify3D has a page (https://www.simplify3d.com/support/materials-guide/polycarbonate/) which describes some of the challenges with 3D printing polycarbonate.

I don’t know if I can print both polycarbonate and PLA or ABS at the same time. Because the temperatures of both nozzle and bed will be different, there’s a chance that I will either not get adherence or the polycarbonate will melt the ABS/PLA during the printing of that material.

Simplify3D says the bed temp should be 110 degrees Celcius for adherence/release. However, I don’t plan on printing directly on the bed, so I will probably use the bed temperature for the other material.

Simplify3D says to set something called ‘coasting.’

I’m still looking for a nozzle temperature. Since Simplify3D say “lower the temp to 280) at one point, I presume the temp should be 300 degrees Celcius or higher. This page talks about using 290-310 degrees Celcius. (https://www.matterhackers.com/articles/how-to-succeed-when-printing-with-polycarbonate-filament)

There’s a youtube video describing how to deal with settings in Simplify3D (https://www.youtube.com/watch?v=JFynhtvPBPQ)

Simplify3D talks about printing different sections of the model with different settings: https://www.simplify3d.com/support/articles/different-settings-for-different-regions-of-a-model/.

Gizmodorks has a nice section on the various 3D printing material types (https://gizmodorks.com/blog/3d-printer-filament-types/).
