Hi there !
I need to print a Cover for a Light that will be placed on a Maschine, and it has to be printed with ABS ( View-1.jpg). It's round about 16cm*16cm and has a height of 4cm.
No matter what i have done...warping has happend all the Time. I tried Glue first - that was not helping - needed to abort print. Then I used ABS-Slurry which was
a lot better (covered the whole Glass with a Spraygun to get it the same hight everywhere - and leveled Bed every time new) ...but still warping ( Bending.jpg).
First we modelled a little groove on the bottom to close the Cover against wetness underneeth - but I deleted this in a next try with still the same Problem of warping.
Last try I added a Rim of 15 Lines and the adhesion seemed to be that high that the Layers split apart on the Edges ( splitting.jpg). :(
Because the Model is big it takes a long time to print it - round about 20 hours. Now there are a few things left to try....
I heated the Bed with 100°C and 110°C ....could it help to print on a lower temperature ?
I printed with Nozzle-temperature 250°C slower speed (40mm) and 260°C higher speed (50mm)....has the Speed an effect on warping - because it happens after a print-time
of round about 10 hours on this Model....is it better to get the Model finished fast or slow ? I have the different Speeds in Expert-Mode of Cura set low to get a good Quality,
but at least I need the Model without warping !
Thanks for fast help - I need 8 of this Parts in the next 3 weeks !!
