Testing ColorFabb nGen: can I do better than that?

Recommended Posts

I've printed the famous ctrlV test (download it here) using ColorFabb nGen. I'm using it instead of PLA because I need outdoor resistance to moisture (rain) and temperature (from -10 °C to 50 °C).




Ultimaker 2

Temp 230 °C

Bed 75 °C

Fan 0%

Flow 100%


I'm a newby. Do you think I can improve this print? How?

Whoa that looks bad.

Yes you can greatly improve on it. It can get a better appearance then PLA.

Firstly change all the speeds so the are the same. For the best quality, the amount of flow through the nozzle needs to be constant as your set temp is constant. Changing speeds means that the slower speeds have less flow and can over heat, while the faster speed have over twice the flow and can be to cold. So you have to then experiment to find the correct temp for you desired speed.

You can however have a fast travel speed. On my UM2 I have it set to 250mm/s and my UM2go is set to 300mm/s

30% infill is quite high, I normally use between 10 and 20 depending on the model.

For nGen I normally have 30% fan.

    • "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.
