Annoying wires on final print!!!

Recommended Posts


I have a problem with my prints:

I printed that object and it took me several hours to remove extra PLA around every element; now i know that the nozzle had to move every time from a place to another and that was the result but can I actually do something else from the beginning to solve this problem?

I use retraction speed 10mm/s and length 0.5mm, witch is a little lower than default but when i raise them it make holes in the object. Other settings: 0.09mm resolution, 230 degrees temperature, 100% speed (it is one of the first good prints with 100 percent speed), material PLA.

Does anyone knows what my problem could be?

Yes this is called stringing

One thing that is probably no helping is the high temperature you are using. To reduce stringing print as cold as possible. The fact that you reduced the retraction setting is also a reason.

If you have underextrusion (the holes you mention) then you need to print slower or clean your nozzle (maybe it's clogged partially)

    • "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.
