Hi RobotArms24!


The infill is set in the printer settings (not in the model) and it's typically only used for FFM-machines (the typical home desktop 3D printers). Shapeways will always make a solid model, I believe.

I usually print with something called "fast honeycomb". There are lots of alternatives, but I feel that fast honeycomb is a good combination of strength, speed, weight and also the zig-zagging gives less pull on the edges and less warping of ABS prints.

I use a software called Simplify3D. They have a lot of good information on their web site. This is a video on infill:

And they also have and this very helpful 3D-printing troubleshooter:

I don't know exactly the strength of different infill percentages, but to the hand it feels linear, i.e. 20% feels twice as strong as 10%.


Best regards,
Stein :-)
