3D printer calibration tools

As anyone who has done a bit of developing and printing in photograpy knows that getting the correct exposure is essential, the same is true for 3D printing.

There are multiple different exposure test prints available, but recently came accross these two.
Both from members of the TableFlip Tabletop gaming community.
Cones of calibration was created first, then the cubes of calibration.


Cones of calibration
You will need to download the calibration tool archive (the link is in the show more) - it's free
And follow the instructions



and

Cubes of calibration
This one takes a slightly different approach, you are printing to an exact size. Again follow the link in the summary to download the files.



I'm away to do some print tests

Hi Jim

Yes for resin 3D printers.

For FDM (filament) printers, you would have to play with layer height, and scaling to get the correct size. You may have to create several size cubes. Print and measure to see if there is a constant scaling factor you can apply, otherwise it may be a print by print adjustment.

And needs to be done for each resin or filament batch, may even need to be adjusted for temp as well

Viscosity is also an issue for us in the colder climes, and most of the published guide data is based around an ambient temp of 25C, probably 5C above my melting point .

When I build my permanent print area, it will have some form of temp control and fume extraction. Hopefully soon so I can get the smell of IPA out of the house.

A little further on the tests for resin

From Vogman



And again now using the Cones of calibration



The cones appear to be a good validation test for new batches of resin, or a confirmation of the resin settings as the resin ages. Resin has a shelf life of between 1 and 2 years (depends on the resin).

And now adjustments to reduce layer lines using Antialiasing and image blurring

I have recently upgraded the firmware on both my mono X's, so will give it a try.
