Printing PC filament on a budget printer can be a challenge due to its high printing temperature requirements and tendency to warp. To successfully print with PC filament, certain upgrades are necessary. Firstly, the stock nozzle of the printer should be upgraded to a higher quality nozzle such as the e3d v6 or Mosquito. Additionally, the bowden tube used should be capable of withstanding temperatures up to 300 ℃, such as the Capricorn tube. It is important to note that even with these upgrades, the nozzle temperature should be set at a minimum of 280 ℃ for optimal printing results.

In terms of the heated bed temperature, cheap printers may not be able to reach the recommended temperatures of 135 to 150 °C. To overcome this limitation, using a polycarbonate build surface can be a viable solution. Polycarbonate sticks well to itself at just 85 °C, providing a suitable printing surface for PC filament.

One important factor to consider when printing with PC filament is its tendency to shrink when cooling down. This shrinkage can lead to warping or layer separation in the printed part. To minimize this issue, it is recommended to print smaller parts to reduce the forces exerted during cooling.

Overall, while printing PC filament on a budget printer may require some upgrades and adjustments, it is still possible to achieve successful prints with careful temperature management and the use of suitable printing surfaces.
