A guide for filament testers on recording settings per material: what to note before a test, how to mark each result, and tools that can keep the record.

By TexHouse · 2026-10-23

TexHouse is published by the makers of LunarWerx 3D Print, Vector3D and MeshyDL, which are compared here alongside other tools.

Documenting settings per material means giving each filament its own entry with the values that worked, then keeping that entry next to the printer so a good result can be repeated. The entry is only useful when it also names the machine, nozzle and plate that produced the values.

What you need before you start

Documenting settings per material is mostly about deciding what a record holds before the first test, because a note that changes shape every time cannot be compared with the last one.

Have the spool in hand and write down the material, the colour and whether it has been dried. Two spools of the same material can need different values, so the spool, not just the material name, belongs in the record.

Have the printer side ready as well: the machine, the nozzle size, the plate surface and anything changed since the last test. An ironing setting or a flow value means nothing without the hardware that produced it.

Set up a test print that shows one change at a time and can be read by eye, such as a plate of pads that can each be marked as worked or not. Keep a pen next to it, because an unmarked pad turns into a guess a week later.

Decide where the notes live before the first print and keep that place the same, whether it is a notebook on the bench or a file on the computer that runs the printer.

Step by step

Write the baseline first. Record the printer, the nozzle, the plate surface and the material with its colour and drying state. Everything after this step is a change against that baseline, and a value copied without it cannot be trusted on another machine.

Change one setting at a time. If flow and temperature both move between prints, the next note cannot say which one made the difference. Leave the rest as they were and write down what moved.

Print a test piece that shows the change. A plate of pads at different values in one print gives several results from one run, and each pad can be looked at on its own.

Mark every pad as worked or not and write the value that ran on it. A pad marked as good with no value beside it only tells you that something in the set was right.

Record the result under the material name, not the spool colour alone. Write the value, the test piece it came from and the date of the test.

Keep the file that produced the result. Settings in a file can be reused; a number in a notebook has to be typed again, and typing is where mistakes creep in.

Start the next material from the closest note you already have, then test again. A record from a similar material narrows the first test, and the test still confirms it.

Recheck after any hardware change. A new nozzle, a new plate or a re-squared machine can move the values that worked, so an old note becomes a starting point rather than an answer.

Keep the notes where the printer is. A record in a folder nobody opens during a print works out the same as no record at all.

Copy the finished values into the place the next job starts from. That may be a printer profile, a project file or a printed sheet taped to the bench, and it should be the same place every time.

Tools that can do it

Several ways of keeping filament settings exist, and the ones here are options, each described only as far as its source allows.

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] and you use it on its website, which is hosted on Cloudflare. ^[1] The tools are free to use. ^[1]

For ironing, it works out ironing 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] One checkbox slows just the first layer to 15 mm/s by default; LunarWerx 3D Print says it then sticks to a clean plate without glue. ^[1]

For an uploaded Bambu or Orca project it adds per-object ironing settings and keeps the rest of the file unchanged. ^[1] When you open an STL file with faces turned backwards, it turns them right side out and says how many it fixed. ^[1]

It runs in your browser, and sign-in with Connections lets your settings, recent test plates and print results be available through that account. ^[1] The code package is marked private, not public. ^[1]

A paper log kept with the spools is the simplest option, with a line per material and the values written in after each test. A spreadsheet on the printer computer is another, with a row per material and a column per setting, which can be sorted by material name when an old spool comes back after a long gap.

Common mistakes to avoid

Changing two settings between tests is the mistake that costs the most time. The next note cannot say which change helped, so the test has to be run again from the start.

Writing the result on the spool only is another. The spool runs out, the label goes in the bin, and the values that worked with that material go with it.

Recording a value without the nozzle or the plate is a quiet error. A setting copied onto a different plate can look wrong even though nothing about the material changed.

Trusting a mark remembered rather than written is a mistake on a plate of pads. Two pads close in value can look the same under bench light an hour later.

Keeping the exported file somewhere that gets cleared is a slow loss. The values in the note then have to be rebuilt by hand, and that is where a decimal slips.

Leaving the drying state out of the note is easy to do and hard to spot. A spool that printed well after drying and then sat out in the open will not repeat the result, and the note will not explain why.

Frequently asked questions

How do you document filament settings per material?

Give each material its own entry and fill in the same fields every time: printer, nozzle, plate surface, material and colour, drying state, the values that worked and the test piece they came from. Keep the file that produced the result with the entry, so the values can be reused rather than typed again. Recheck the entry after a hardware change, because a note without the machine it came from can mislead the next test.

How often should filament settings be rechecked for a material?

Recheck the values whenever the nozzle, the plate surface or the printer changes, and when a new spool of the same material arrives. Start from the last note for that material and run one test piece before a longer job. A note written months ago is a starting point rather than a guarantee, because a dried spool and a damp one do not print the same.
