{"product_id":"dimensional-correction-test-piece","title":"Dimensional correction test piece","description":"\u003cp\u003eHere's a dimensional test object I created to calibrate my printer and make sure I was printing dimensionally correct parts. The end result of this process is accurate scale figures you can use to make sure parts fit tight tolerances. The piece includes 6 100mm measurements in the X direction, and 6 in the Y. The protocol I used was to measure each of these 3 times, giving 36 total measurements.\u003cbr\u003e \u003c\/p\u003e\u003cp\u003eIt's not very easy to correct for X\/Y skew in bambu studio, however, using this piece I was able to determine that the scale factor I needed for dimensionally accurate ABS, was equivelent to what the thermal expansion was. I can imagine a use cases for this print: making sure your printer is dialed in, determining if you have significant X\/Y scaling issues (not a problem for me), or determining the scale factor you need for a new material.\u003cbr\u003e\u003cbr\u003eI've included a sample calculation here: \u003ca target=\"_blank\" href=\"https:\/\/docs.google.com\/spreadsheets\/d\/e\/2PACX-1vTmJj0n_KWD1p4YhHnH3_yh-n6kqhBvkYMBoA1sziJdUuPQxl_UmbK5K7rfRINvHJ_IOk7Ggc3IUz72\/pubhtml\" rel=\"nofollow noopener\"\u003ehttps:\/\/docs.google.com\/spreadsheets\/d\/e\/2PACX-1vTmJj0n_KWD1p4YhHnH3_yh-n6kqhBvkYMBoA1sziJdUuPQxl_UmbK5K7rfRINvHJ_IOk7Ggc3IUz72\/pubhtml#\u003c\/a\u003e and will attach a spreadsheet for you to do this calculation yourself.\u003cbr\u003e\u003cbr\u003eIn my tests, printed out several of these pieces, corrected for scale, and printed again. Eventually, I converged on the scale factor required being equivelent to the theoretical thermal expansion for ABS.
