Summary

This is a 3D printing speed test. It consists of two 3D models, optimized fortesting speed and acceleration of the perimeters and the infill respectively.You can use these to tweak your speed and acceleration settings and lookfor quality issues (e.g. ghosting, surface quality), problems like layeradhesion or mechanical limitations (layer shifts). How fast can you go?

For the purpose of comparability, I recommend the following print settings.

General

• The stl files are designed to provoke ghosting on the X and Y axis andto test the infill.

• Recommended material: Standard materials like PLA, PETG, or ABS.Materials with shiny and silky surface finish will show ghosting moreclearly. For that, you can also increase your print temperature slightly(5-15 °C) to make the surface shinier.

• Also adjust settings as "max print speed" and "max volumetric speed"if you go very fast; e.g. 180+ mm/s to ensure that the desiredperimeter speed is applied.

• If necessary, decrease „Slow down if layer print time is below“ toabout 3 sec in the filament settings to ensure that the desiredperimeter speed is reached Ghosting Test (Perimeter speed)

• Settings: 0.2 mm, 2 perimeters, linear advance on, top/bottom layers:0, no infill

• Interesting speeds/accelerations: Perimeters, External Perimeters (Itis recommended to set both parameters to the same value for thetest)

• The model features offsets of 1mm (bottom), 2mm (top), straightlines for reference (middle), embossed text, sharp corners, and awiggly path

• What to look for: Ghosting, layer shifts, layer adhesion, surfacestructure on the outside and on the inside Infill Test (Infill speed)

• Print Settings: 0.2 mm, 2 perimeters, linear advance on, top/bottomlayers: 0, 12 % infill

◦ Infill pattern: Cubic (This pattern features straight lines whichallow acceleration to the maximum speed and pissues as layeradhesion, layer shifts are easily visible.

• Interesting speeds/accelerations: Infill • What to look for: Surface structure of infill, layer shifts, adhesion

Important Notes:

Always make sure the gcode is really using the desired speeds. Keepin mind that parameters like "Max volumetric speed" or accelerationscan limit the attainable printing speed. It is recommended to checkthe speeds in the gcode or in the Slicer PE preview every time beforeyou print. Slicer PE does only show the max speed for a move.However, acceleration and deceleration must be considered. If youincrease speed settings and the print time does not change evenwhen Slicer PE shows higher speeds, it is a clear indicator that thereached speed is limited by the acceleration. Also, the desired speedwill only be reached after a certain acceleration distance. Keep that inmind and examine especially the middle section of straight moves.
