4x PLA 70mm front-end loader prints all show scarring

Recommended Posts

Posted · 4x PLA 70mm front-end loader prints all show scarring

I'm printing some front-end loaders for my US friend's grandkids, @ 70mm width, in various PLA colors. The original miniature model was created by agepbiz and posted on Thingiverse. I've resized it to 70mm in Cura 2.3.1 and have printed 4 of them.

I created the supports in Meshmixer and scanned it for mesh defects, and also sent it to NetFabb for checking and used the resulting model in the UM2+.

Printing mostly went well but every print has a scar on the linkage between the loader cabin and the front end. I've posted some pics here:

Thank you for any pointers!

I guess I can heat-weld some filament in the scars.
