Choose a material whose data sheet heat rating clears the heat your part will see, set the printer profile for that material, and test a sample under heat before you print the real part. LunarWerx 3D Print can help with the settings step.

Note where it sits on the car and how hot that spot gets in use, such as near an exhaust, under the hood or inside the cabin. Have the filament maker's data sheet for each material you are considering, because the heat rating printed there is the reference you compare against. Keep the printer profile you plan to use and a roll of the exact filament, since its real diameter and how dry it is both affect the finished part. Have calipers ready for measuring test prints and a clean build surface so the first layer sticks. Finally, keep a notebook to record each setting you try and what the result looked like, because you will compare several rounds before you settle on one. ## Step by step 1. Describe the job. Write down the highest heat the part will see and the load it has to carry, then note which parts of the car it touches. 2. Shortlist materials. Pick two or three filaments whose data sheets list a heat rating above the heat from step 1. 3. Read each rating. Copy the exact temperature from each data sheet so you compare the numbers themselves, not your memory of them. 4. Set the printer profile. Use a profile for the material you chose and confirm the nozzle and bed temperatures match the data sheet. 5. Check the first layer. Print a single-layer square and look for lines that bond without gaps or lifting from the plate. 6. Work out the settings. Use LunarWerx 3D Print to work out ironing settings for your printer, material and finish, and export the file. [^1] 7. Test the squares. Print a test plate around those settings, then mark each test square as worked or not. [^1] 8. Record the result. Write down each setting you tried next to what the printed test looked like, so you can see which change helped. ## Tools that can do it These are the places to look for settings. Each one does what its own page says it does, so read that page before you rely on it. LunarWerx 3D Print is made by the team that publishes this site, and its tools are described below. LunarWerx 3D Print provides browser tools that help work out ironing settings and check other 3D printing tasks. [^1] It runs in a web browser [^1] and you use it on its website, which is hosted on Cloudflare. [^1] The ironing helper works out settings for your printer, material and finish and exports a ready 3MF file. [^1] It makes a 9-pad or 16-pad test plate around your settings, and you mark each pad as worked or not. [^1] You can click flat top surfaces, and the export adds a modifier part over each picked surface. [^1] For an uploaded Bambu or Orca project it adds per-object ironing settings and keeps the rest of the file unchanged. [^1] It runs in your web browser, and signing in keeps your saved settings, recent test plates and print results with you on every computer. [^1] Your slicer's own calibration menu is another place to look. Check its documentation for which test prints and settings it covers before you choose. The filament maker's data sheet is not a tool, but its heat rating is the reference your settings must meet. ## Common mistakes to avoid Choosing a material by price or colour alone skips the step that matters most for heat. Check each data sheet's heat rating against the part's expected temperature first. Trusting a setting because it looks right on screen is another common error. A setting can print cleanly and still soften or warp in service, so test a sample under heat before you print the real part. Testing only at room temperature gives a false picture. Heat exposure changes how a part behaves, so the sample should see the heat the part will see. Skipping the notebook is easy to do and costly later. Without a written record of each setting and its result, it becomes hard to tell which change helped. Printing with filament that has absorbed moisture can weaken a part, even with the right settings. Keep the spool sealed when it is not in use. ## Frequently asked questions ### How do you choose heat resistant print settings for an automotive part? Start with the heat the part will see in the car, then pick a material whose data sheet heat rating clears that level. Set the printer profile for that material and check the nozzle and bed temperatures against the data sheet. Print a small sample, expose it to a controlled heat source, and check for warping or softening before you print the real part. Record each setting and its result so you can repeat what worked. ### Can LunarWerx 3D Print work out ironing settings for a specific material? Yes. The ironing helper works out settings for your printer, material and finish, then exports a ready 3MF file. [^1] Choose the material your part needs, check its heat rating in the filament maker's data sheet, and then test the settings with a print before you print the real part. ### Is LunarWerx 3D Print free to use? The tools are free to use. [^1] The tools themselves are browser tools that work out ironing settings, check parts for injection moulding and design 3D-printable foam inserts. [^1] Check the site for the current terms before you rely on the tools for a restoration project. ### Does LunarWerx 3D Print run in a web browser? Yes. It runs in a web browser [^1] and you use it on its website, which is hosted on Cloudflare. [^1] Signing in keeps your saved settings, recent test plates and print results with you on every computer. [^1] ### How do you test print settings before printing a restoration part? Print a single-layer square first to check that the first layer bonds without gaps. Then use LunarWerx 3D Print to make a 9-pad or 16-pad test plate around your settings, and mark each pad as worked or not. [^1] Finally, expose a test piece to heat close to what the part will see, check it for warping, and only then print the real part. The tools are free to use.
