Recommended Posts

20180523_172043.jpg?width=226&height=301

 

The one below is taulman bridge, no prob

in the middle, colorfabb PLA, no prob

Up, taulman bridge but printing 20 same models at the same time, Not good on any of them

 

They all use the same settings, can't find the way to copy/past all settings from cura and I'm shure, the settings I'll give you will not be relevant ^^ I'll just say 100% infill, 70mm/s speed, 6.5mm restractation.

 

merci beaucoup !

Can you share a picture of it? Just because it doesn't look burnt doesn't mean it's not worn out. The more subtle wear and tear signs are:

* It's not round anymore

* The opening at the bottom is wider than it used to be

* Scraggly edges/lips that will catch the filament.

 

How many print hours are on your printer? Maintenance --> Advanced --> Runtime Stats.

Hey 🙂

The printer has 1200hours, in 3years ! I'm not a big user I guess 😛

 

The narrow end was aliitle rough, so I trimed it a little ( not very good at it ^^ ) filament could pass smoothly and still can... But it's allitle tiny bit ovale !

Should I change it ?

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
