Printing Fast = Matte Surface Finish

If you ever notice that your print may be more matte on one section than another - this is more than likely due to the fact you a printing too fast for the hotend and material you are using.

Materials that are not meant for high flow printing will often turn a more matte finish when attempting to extrude too fast. This is because the material is not given enough time to heat to its set temperature.

If you want to print fast and maintain a shiny surface finish - make sure you are using a high flow material with a high flow hotend.
