Summary

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".

Prints:

  1. Dimensional Accuracy
  2. Bridging Performance
  3. Overhang Performance
  4. Negative Space Tolerance
  5. Fine Positive Features Performance
  6. XY Resonance
  7. Z Resonance

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

Is the Negative Space Test radial or diametral? I.e. - does "0.2" refer to the difference in diameter of the pin and hole (in which case, the precision would be down to 0.1), or difference in radius (in which it would just be 0.2)?

I did the negative hold test. 6 - 4 came out off the bed. 3 needed a little push. But 2 is stuck in there.
What do i need to do to be able to get my printer printing that.

are theese things supposed to be printed without any support or with them?

How to evaluate link is dead!

Where can I find the actual test prints by the printers tested by Make?

What type infill would you recommend for printing these tests? Hollow or a light infill?

10%-20% is pretty standard. Most of these should be printed with the machines medium or standard settings so we are relying on the settings the vendor recommends.

Instructions link ("Learn how to evaluate the test geometries at: http://wp.me/p22K2I-1TOt ") heads to locked file? Is there anything more than on the web? (www.makezine.com/2014/11/07/how-to-evaluate-the-2015-make-3dp-test-probes/) – I want to compare my test prints (including robot with joints) from MakerBot Replicator with those from the last 3D printers roundup. But if I will use partly different methodology, it will be hit and miss procedure. :o)

I will look into that and see what happened to the link.

The abbreviated link is still leading to a private wordpress site. However, I was able to open the www.makezine.com link that tomulinek provided in his comment.

These calibration prints are almost completely useless without some way of correcting the errors. Any fool can hit print and rate the print but how are we supposed to improve the prints?

MAKE - in reply to GPPK

These probes are just to compare the machines in a more scientific fashion. We were not looking for a way to tell you how to tune your machine.

The problem with giving recommendations for "fixes" is that this may be different for every printer. Some things can be fixed in the slicing profiles, if the user has access to those. Other issues are inherent to the hardware of the machine and would take a manufacturer (or user created) upgrade. I suggest looking for super users of your machine on forums dedicated to that machine for details on how to get better prints from your particular printer.

True! I wish they had a guide on how to fix it...

For the accuracy/backlash test, I suggest that people report the measured length of the diameter in the X direction and the Y direction so that there will be a clear picture of where different people's results differ.

Including the print time is important because slower printing may increase the quality of a print.

The "how to evaluate" document linked on the instructions page could be better. The document only details scoring in seven categories, while the magazine scores are broken into ten. It would also be very helpful and scores people come up with would be more consistent if pictures of prints and the scores they would get are provided - some of the scoring descriptions aren't all that clear.

I think you should add to the description or the instructions here to include your...

Great suggestion. Will do!

The instructions have been updated. Thanks!
