Infill splits

Recommended Posts

Hey guys.

Just started printing with ABS so not sure what to expect. I finally managed to get it to stick to the print bed with some tape, but now i've found that the infill seems to be pulling apart where the lines of infill meet (only using a 15% infill). I was playing around with the settings when i noticed this (bumped the speed up to 200% of 50mm/s) so I'm not sure if this is due to the speed change or it's something that would have happened anyway.

Any advice would be great

Thanks :)

ABS often has a problem with upper layers not melting the next layer down enough such that the layers can separate easily.

So: Are you talking about "layer bonding" or something different? bonding within the same layer?

Anyway the first thing, "layer bonding" or "layer adhesion" is common with "high glass temp" materials such as ABS, Nylon, etc. One fix is to turn off the fan. This works well for ABS. I print at 245C usually with fan off. I guess the quick answer is: "higher nozzle temp, less fan".

Another solution is to use a heated chamber. Simply print with 110C bed, and enclose the top and front of the printer to keep the heat inside.

i haven't had a lot of problem with layer bonding, the problem seems to be on the same layer. when the mesh which makes up the infill crosses to make the square shapes, the corners start to pull apart, like the wall of a box pulling away. i haven't printed a lot with ABS just yet, so i don't have any photos of the problem yet. i'll take some the next time it happens

      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "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.
