ABS printing not very good...

Recommended Posts

Hi gurus,

I'm trying to print out this tiny object:

As you can see the result (printed in ABS) is not very good: borders are not clean and so on.

I tried to print the same in PLA and the result is much better. Any suggestion for the ABS settings: I tried with 245 degrees and a layer of 0.2. It looks like there is a bit of overextrusion, or am I wrong?

Settings are:

print speed: 100mm

fill densiti 100%

tem: 245

flow 100%

Thanks,

It's too small... print several at a time and make sure your retraction is set right... possibly up it from 4.5 to 5 in the menu. The fan idea is good if you're trying to print one at a time, but remember the heat from the hot end will deform the part unless you can move that heat away for bit... hens multiple prints at a time.

Try right clicking the part i normal view and multiplying it by 5 (6 part total) and seeing how they come out....from there you can gauge how it prints... multiple vs. single parts

    • "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.
