PLA + Breakaway Surface Quality Issues

Recommended Posts

Posted · PLA + Breakaway Surface Quality Issues

I am trying to implement Breakaway in an academic maker space and I am running into some issues with surface quality.

 

To start:

I am using a UM3 with Ultimaker brand PLA and Breakaway. The machine being used for the test is serviced on a monthly basis and has no other issues.

Slicer settings:

(Default for Cura if not stated)

Layer height: .1

Infill: 40%

Model Extruder: Extruder 1 (PLA)

Support Extruder: Extruder 2 (Breakaway)

Support Z distance: .1

Prime Tower: Enabled

 

I came to these settings after looking through the forums on topics related to Breakaway but my search didn't lead me to anyone with my same issue.

 

Here is an example of the surface issue:

The area on the top of the print is what I am concerned about. In all the test prints I have done, this surface warping has occurred to some extent. I have tried Support Z distances between .1 and .3 with prime towers on each print and this continues to happen.

 

Has anyone else had this issue? The rest of the print looks great and I would really love to solve this so that we could use it in our space.

 

Thanks!

I don't have a dual nozzle printer, so just guessing:

 

When using dedicated support materials like breakaway or PVA, shouldn't the gap between support and model be zero? So that they are squeezed well together for a good bonding?

 

Maybe you could try this on a couple of small test pieces?

I will give that a try, I have tried these tests now on two machines and I get roughly the same result so it seems like a slicing issue. Thanks for your input!

    • "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.
