Side pealing off

Recommended Posts

Why would the side peal off like this? It seems to go all the way down to the first layer.

Pealing off

Printer did have underextrusion problems (too high speed as it was just a test print for size). Is underextrusion the reason? Why?

Printed on UM2 in PLA, layer 0.2mm, shell 0.8mm, speed 50mm/s (changed to 30mm/s half-way into the print once I noticed the underextrusion issue).

Look at this graph when choosing temperature's and speeds. At 210C and .2mm layer height the absolute max speed for a UM2 is about 60mm/sec (blue line in graph). You were too close to that absolute limit. I recommend you don't exceed half the max speed (30mm/sec should be fine at 210C). Anyway if you want to print 50mm/sec and .2mm layers then the graph tells us 240C is about right. I print at that speed often but if you want higher quality I would stick at 210C and 30mm/sec and be patient.

Also note that different colors of PLA and different brands may need 10C or so hotter or cooler than the brand used for the graph test (UM light blue).

    • "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.
