Solid layer fill behavior causes difference in coloration

[jrgandara]

Hello!

I´m having a hard time trying to achieve a quality solid layer fill with Simplify3D when there are holes on the plane. Let´s say I want to print a square box. If this box have no details on top, the layer fill will do a nice and clean job. The look and feel is quite nice printed with Original Prusa Mk2. But if there is a hole in the top pf the box, when the fill reaches the hole, it will kick back and let a void in the other side of the hole which will be filled later. But when filling this void later, the color and pattern of the continuation is different. Maybe because is adding plastic to a already cold plastic. So this print end up with a lot of tones and different lines. My question is:

There are any configuration where I can prioritize the fill and if there are any obstacle in the way, like a hole, the fill just jump the obstacle and keep going until reach the opposite edge and come back until fill the whole layer without jumping randomly?

Hi, I don't believe there is a setting to do what you are asking.

One way to overcome the problem is to cover the holes with a single layer of skin, i.e. make the holes stop before they reach the surface. If you do that, the surface will be printed without interruptions and then when the print is finished, you need to remove the single layer of skin that covers the holes.

This is normal behavior when the top or sides etc. aren't one solid plane. No setting I am aware of to change it.
"Smart's" idea is a good one that might work in most places.

You can find this idea and some other good stuff here...

It's aimed at Ultimaker 2 users but a lot of it is generic and can be applied to any printer.

Colour variation in the vertical direction also occurs when perimeters are printed at different speeds so to achieve the most uniform colouration disable the minimum layer time feature that slows the printing down. Obviously, if the model is small, you may get overheating by doing this so more settings may need to be tweaked.

Thanks for the info.
