Topic: effects of infill pattern on warping?

Has anyone ever tested the effects of infill patterns on warping?
In other words, does one particular pattern seem to increase/reduce warping problems?

I have historically used the honeycomb infill pattern but switched up the other day to linear because it ran my print quicker.  that got me to thinking (since these parts tend to warp) if the pattern could effect this issue.

Great question!

I have never tested this, but I would submit that the pattern using more plastic (than another) would have a worse effect on warping.  The more mass of the infill=the more material to contract=more of a tendency to warp.

Although that would make theoretical sense I print almost everything at 100% infill (linear of course) and warping is really no more of an issue than with less infill.  Of course this doesn't answer the question of pattern effecting warp.  That's a good question worth some exploration.

Yes...I suppose the variable to make note of here is that with good adhesion to the printing surface (through adequate heating of the bed and hairspray or whatever medium would be applied) then warping is typically not an issue no matter what the infill pattern or density.  I too do not experience much warping even at 100% infill since I have a PCB bed heater running at 100C+ and an enclosure to keep the environment a bit toasty smile

One would almost need to run the bed at about 60C to perform the tests...would probably have some interesting results!

Re: effects of infill pattern on warping?

in my test, the worst warp is with rectilinear infill, the minimum warp is with honeycomb (but it's slower) using the same % infill

Honeycomb also helps prevent holes in round hollow objects caused by rectilinear pulling/distorting sides

Solidoodle 2 with Deluxe kit cover & glass bed with heater. and 2nd board SD2 used not 3rd and alum platform not installed yet still wood. also need cooling fan installed to board. use Repetier Host couple vers. Slic3r also have all free ware STL programs
