A smart compensation test for 3D Printing
A compensation test allows you to determine how much your printer oversizes parts, so that you can design around that and create accurate to size parts.
This is the most elegant compensation test you will ever see!
It's a one-of-a-kind gauge that relies on a slight taper. This design foregoes the typical binary go and no-go style, and gives us powerful results, easily.
It prints very fast relative to other gauges, requiring very little filament, yet it still gives full range from 0 mm to 1 mm, plus fine decimals!
Never pile up bulky go/no-go tests again! It also makes an attractive ornament when finished.
The bottom has a square width of 20mm, and gently tapers to 19 MM over 60 MM.
The ring has a 20 MM inner square width.
How to Print
Print using a spiralized contour, otherwise known as "vase mode."
How to Use
To perform the test, the ring is gently slid onto the tower to see how far the ring can travel before stopping.
Measure the distance (in millimeters) left from the bottom of the ring to the bottom of the tower.
Insert this distance as "X" in 1/60(X)
The result should typically be a number between 0.15 and 0.6, which is the amount in MM your printer must be compensated for in your future designs.
For example, if the bottom of the ring was 20mm away from the bottom of the taper, you would enter 1/60(20)
That would equal 0.33 MM.
Therefore, in order for your printer to produce a ring which fits perfectly onto a 20mm wide square block, the ring's inner dimension must be designed to be a minimum of 20.33mm, or the block must be reduced to a maximum of 19.67mm.
- You can vary the amount of force applied in the experiment to adjust whether the part design you are considering will be a snug or loose fit.
I like to find both a minimum and maximum compensation amount, where the high and low numbers found represent a scale of snug and loose fitting parts possibilities.
You can run the test several times and find the average, if you are so inclined.
Once you typically fall under a specific compensation, you can cancel the print mid way to save even more time and filament!.
- Additional tests may be ran to determine compensation requirements for different speeds, temperatures, and more!
