What you need before you start

Before verifying dimensional tolerances before printing, have the final part requirements ready. Record the dimensions that affect fit, movement, assembly, or contact with other parts. Keep the original CAD model available so printed results can be compared with the intended design. Decide which areas need the closest checks and which dimensions have more room for variation.

Prepare the printer information, material choice, and planned print settings because these can affect the final part. Have measuring tools ready for checking printed features after a test print. Calipers, gauges, or other measurement tools can help compare the finished part with the target dimensions.

A clear list of critical features helps avoid checking the wrong areas. Focus on holes, slots, mating surfaces, walls, and other features that control how the part works.

Step by step

  1. Identify the important dimensions. Mark the features that control how the part fits or works before printing. These are the areas that need comparison after a test print.
  1. Review the model before printing. Check that the design dimensions match the intended function and that the selected tolerances make sense for the material and printer process.
  1. Choose a measurement method. Decide how each feature will be checked after printing, including which tool will measure the size, position, or fit.
  1. Print a test part or representative feature. Use a design that includes the dimensions that matter so the result can be compared with the target.
  1. Measure the printed result. Record the actual dimensions and compare them with the design values. Note where the print differs from the intended size.
  1. Review the cause of differences. Check whether the change comes from the design, material behavior, printer settings, or the measurement method.
  1. Adjust the design or print settings. Make changes based on the measured result and repeat the check when the tolerance is important.
  1. Verify the final version. Confirm that the updated part meets the required dimensions before moving to production or use.

Tools that can do it

Several tools can help with parts of dimensional tolerance checks. The tools here are options, and each does what its source says it does.

LunarWerx 3D Print is made by the team that publishes this site. It is a set of browser tools that work out ironing settings for your printer, check a part for injection moulding and design 3D-printable foam inserts. [1] It runs in a web browser. [1] You use it on its website, which is hosted on Cloudflare. [1]

For checking parts before production decisions, it checks a part for injection moulding with 13 checks, shows shrinkage, pressure and weak-point maps, and builds the two mould halves; all numbers are estimates. [1] It can also help prepare physical part storage by laying parts out in a box and designing a 3D-printable foam tray and top pad that each part lifts straight out of. [1]

LunarWerx 3D Print can also help with other print preparation tasks. [1] It works out ironing settings for your printer, material and finish and exports a ready 3MF file. [1] For an uploaded Bambu or Orca project it adds per-object ironing settings and keeps the rest of the file unchanged. [1]

The tools are free to use. [1] The code package is marked private, not public. [1]

Common mistakes to avoid

Checking only the overall size of a part can miss the features that control whether it works. Measure the areas that affect assembly, movement, or contact.

Printing without recording the target dimensions makes later comparisons harder. Keep the intended measurements with the test results so changes can be reviewed.

Ignoring material and print settings can lead to confusing results. A tolerance that works for one material or setup may need another check when those conditions change.

Measuring a part without a consistent method can create unclear results. Use the same approach when comparing different versions of a design.

Changing several things at once can make it harder to understand what improved or caused a problem. Adjust one factor at a time when possible and record the result.
