My first Mask: what causes the print lines?

Recommended Posts

I've just printed my first mask, in a smaller size to make sure it all works.

The pic is lit from behind and clearly shows the print lines. I rather enjoy what many would regard as a fault - almost like a Maori moko (facial tattoo).

I'll do more research and maybe print a full-size one as in the other pic, and paint it afterwards. All credit to Jacob/JTM: https://www.thingiverse.com/thing:1013350

I would like to learn how to avoid those print lines.

These are the Cura 2.3.1 settings I've used:

- UM2+, PLA, 0.4mm nozzle, normal quality.

- Layer height: 0.1mm

- Wall thickness: 1.05mm

- Top/bottom thickness: 0.8mm

- Infill density: 20%

- Infill pattern: Grid

- Infill layer thickness: 0.1mm

- Enable retraction: On

- Print speed: 50mm/s

- Travel speed: 120mm/s

- Print cooling: On

Thank you!

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
