Hi,
We want to use the hole Printing Room in our Ultimaker 3 Extended.
I tried now several times to print a huge Part (190mmW x 180mm L x 267mm H)
It is a model designt with a lot of thin walls (0.8mm - 2.4mm) and has overhangs which are horizontal an need support.
I would need 900g of PVA, so I used PVA only in the Interface Regions which I made 6mm thick.
To go down with running times below 1 Week, I used 0.3mm layer thickness.
But quality is bad. Does anybody has good settings for huge parts with 0.3mm thickness that work?
Or is it necessary to use 0.2mm layr thickness and let run the job longer?
In the picture you see, that we use RED PLA with transparrent PVA
We hope to get help here. We bought the printer for bigger parts.
Some Details on the settings:
5% support density for PLA (20mm space between support lines, we know the bridging in ultamker is possible to work with this), 15% Support density for PVA, 6mm Interface thickness in Z at bottom and top of PLA-Supports
