Make Magazine's third annual 3D Printing Shootout was conducted using these files, created by Andreas Bastian to benchmark performance of desktop 3D printers. You can read all 26 machine reviews in Make:'s Annual Guide to 3D Printing 2015 (Volume 42).
These test geometries are designed to evaluate specific performance characteristics and motion systems in common low-cost FDM/FFF machines. Traditionally, layer height has been used as a proxy for resolution or quality, but it is a bit of an oversimplification of what is often termed "print quality".
1. Dimensional Accuracy
2. Bridging Performance
3. Overhang Performance
4. Negative Space Tolerance
5. Fine Positive Features Performance
6. XY Resonance
7. Z Resonance

##Documentation and Sharing:
Please use the “I Made One” button on your file sharing site of choice to share your results! Make sure to include the following information with your photo(s) of your completed test prints:
1. Machine make and model
2. Slicer and slicing settings (layer height, number of shells, print temperature, extrusion multipliers, speeds)
3. Print time - start with a room temperature extruder and platform. Begin timing when you start the print, and include the preheat sequence. Keep timing through any post-print sequence, like the extruder or platform returning to a homing position.
4. Filament source
