Simple Printer Speed Test Objects

thingiverse

These items are specifically designed to enable you to test and measure the maximum speed at which your printer can successfully print. They include: 20mm Square 10mm high rectangles with 1.2mm walls and .5mm floors 50mm Square 10mm high rectangles with 1.2mm walls and .5mm floors 150mm Diameter Cylinders 10mm high To use these items, bring one into your favorite slicer and set your speed to whatever you want to test and print them. It's suggested that you use a layer height of .25 for the best results with a .4mm nozzle. To measure your actual average speed, pick a spot or corner and use a stopwatch to check each pass several times to determine how long each pass takes. You can then compare the actual time to the expected time. If you set your slicer to 100mm/sec for the 150mm circle, each pass should occur in approximately 4.71 seconds. The 50mm Square should take around 2 seconds per pass, while the 20mm Square should take about .8 seconds per pass. Each level with a .4mm nozzle will have three passes, making it easier to measure level to level if that's what you prefer. Each of these items tests your machine in different situations. The 20mm square tests your actual maximum speed for small detailed parts, the 50mm Square tests your average sized parts, and the 150mm Circle tests your printer's top speed. You can then use this information to create ideal slicer settings for your future prints based on what you're printing. There are two primary failures that can occur with this test. In one case, your printer may not be able to hold accurate dimensions - 20mm, 50mm, or 150mm. The other case is that your extruder may not be able to extrude the plastic fast enough, resulting in skipping and underextrusion. To improve the printability of the 150mm Circle, try changing the settings to: 3 Perimeters, 0 top layers, 0 bottom layers, and 0 infill. If you have bed adhesion issues, a skirt might help resolve them.
