[holes/circles first layer]

See if Optimize Wall Printing Order makes a difference.  It can effect the print order of inner and outer walls around holes.  When enabled it will print the inner wall and proceed to the outer wall for each hole.  When disabled it will do the inner walls and move on, then come back and do all the outer walls (that face the centerline of each hole).

gr5's video is very good.

It's Aquanet Superhold hairspray that is the ticket for me.

"Optimize Wall Printing Order"   is the right answer!!. This is honestly what I was looking for. This will definitely print all of the wall lines at once when printing circles layer by layer and it will give you stronger adhesion. This option is activated by default in another silicing software. Well done @GregValiant you made my night man!!. Thanks a lot

Thanks very much guys for all of your suggestions. I think @GregValiant ' s idea about "make the Infill Layer Height 2X the regular layer heigh" is best fit for my case. It looks like a really good time saver and the only settings I never experimented with.

I will give it a go.

Thanks. I can see there is always something to Sacrifice between quality/printing time.

 

I've been slicing a very complex skull (approx. 100x100x114mm)

 

- Loads of overhangs

 

- 1.2mm wall thickness 3 wall lines

 

- 0% Infill & 0.2mm Layer height

 

- Speed (40-60mm/s and 30mm/s Top/Bottom) plus 150mm travel speed.

 

 

 

The biggest problem is the time spent building supports even using,Zig Zag build plate only and 12% support density.

 

 

 

But I am afraid If Increase speed It's very likely to brake parts as the nozzle travel between overhangs/bridges or those thin supports. 

 

 

 

I tweaked several acceptable options but I don't really want to go lower than 0.2mm quality neither split the 3d model. 

 

I rotated the 3d model in several positions and still with the above speed/Quality It's so frustrating not being able to get a print under 8 hours.

 

Regards,

Andy

@Ultimaker 2+ why nobody seems to talk about how to keep a good balance Quality/Speed? Real problems are how to print under 8 hours big complex models with loads of overhangs ,very thin walls and it's not feasible to split the 3d model. Any tips for UM2+?
