Infill lines connection problem

Recommended Posts

I am printing something with little squares. But the problem is Ultimaker2 is not combining the vertical and horizontal lines. Using Cura 4.0.0

 

I guess that it is trying to prevent printing over an already printed area but how can I fix that?

 

Thanks in advance! 🙂

So I have seen this exact pattern when printing too fast - like 200mm/sec on my fastest printer.  Slower I suppose on my um2 with the black feeder.  I'm not sure what causes it.  But it goes away when I drop the speed by 50% (which you can do in the tune menu for your printer (looks like it's a um2,um3 or s5)).

 

Please clarify a few things:

1) Please show this or a similar layer in layer view in cura.

2) Did you model a cube and set the top/bottom infill to 0 and use an infill pattern to make this?  Or did you actually model all those thin walls?  You will get *much* better results with the former method.  And it will print much faster (only one pass on walls instead of 2 or more).

Attached a view in cura

It is an UM2 with a 0.15 mm nozzle

Yes it is a cube and I use infill patterns. Line width is 0.15 mm.

Speed is 45mm/s

 

What I want is squares with equal height and connected walls.

 

Thanks!

    • "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.
