Friends who are often exposed to 3D printing should be very familiar with the printing parameter of fill rate. In order to reduce the weight of the printed parts, many 3D printed parts are not solid inside but use a honeycomb-like structure. Recently, Steam Lab conducted a strength test on the internal filling structure of the current mainstream prints. Let's take a look at the results.
Grid
Consists of the intersection of multiple lamellae that provide support. The test results are: the maximum compressive strength is 455.2 kg, the Z-axis can withstand more than 350 kg of force, and the X-axis and Y-axis can withstand about 200 kg of force. The tensile strength is about 50 kg.
Zigzag
The zig-zag structure is similar to the grid structure, but only one set of slices is printed per layer, which is then extended alternately. The test results are: the maximum compressive strength is 435.82 kg, the Z-axis can withstand more than 300 kg of force, and the X-axis and Y-axis can withstand nearly 200 kg of force. The tensile strength is slightly less than 50 kg.
Triangle
It is also composed of multiple slices intersecting but not at right angles. The test results are: the maximum compressive strength is 379.94 kg, the Z-axis can withstand a force of about 350 kg, and the X-axis and Y-axis can withstand a force of about 240 kg. The tensile strength is 13 kg.
Honeycomb
The honeycomb-like structure is supported by hexagons. The test results are: the maximum compressive strength is 430.75 kg, the Z-axis can withstand a force of slightly less than 350 kg, and the X-axis and Y-axis can withstand a force of slightly less than 200 kg. The tensile strength is 12 kg.
