Why not (Fast) Honeycomb?

Recommended Posts

Hi Cura-Team.


I love to use Cura with my UM3E and print a lot large objects. Why you don´t implement fast honeycomb with no overlapping an full honeycomb with overlapping? Fast honeycomb is the strongest and fastest way to print rock solid infills.


So please please please implement at least fast honeycom into Cura please. Rectangle and octo infill cant really beat/substitute honeycomb in stability and printspeed.


I appreciate it so much like other users will do i guess.

I'm not a UM employee but I really don't believe that honeycomb is stronger than all the other infills.  Maybe you mean the strongest for it's weight?  Certainly not the strongest for it's speed of printing.  It's only strong in certain dimensions.  Honeycomb is a bit weak on 2 of the axes I believe.  I think the cube pattern that Cura has might be stronger than honeycomb for it's weight and also for it's speed.


Really the best infill is a gradual infill with higher density near all walls (side/top/bottom) and less infill in the center.  Cura supports this.


Please try to draw a little bit of the honeycomb pattern on paper.  You will see that you can't go very far at all in a straight line.  The printer has to jig and jag constantly.  Making it print very slow.  There is a "triangle honeycomb" pattern that cura supports that is very similar to honcomb but prints much faster (all straight lines).

Geometrically speaking honeycomb pattern an efficient use of 2D space when your trying to make an structure to house a bunch of basically round pupae. I think of it as circles packed tight, without the lost space between. I've never bothered with it due to all the jerking required to print.


My favorite infill for strength is Cubic.  It is a triangular (also results in hexagons) pattern that on subsequent layers, each line also shifts, creating sloping line that form tetrahedrons inside your part.  Since it is straight lines, it prints fast.  It seems cubic would be the best candidate for gradual increasing infill (or support) as you print up. I say this because each new infill wall could be placed such that it has support starting off an existing infill wall.  On the other hand, gradually denser grid or line infill (or other straight vertical infill), always result in a lot of unsupported overhangs at the start height of a new course.  Am I making sense i that explanation?


Cubic Subdivision, Octet, and Quarter Cubic are similar in that the infill walls are sloped, and should also yield the same benefit to gradually increasing infill.  I can't distinguish the difference between Octet and Quarter Cubic or between Cubic and Cubic Subdivision.

      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
