Steps Etsy print sellers can follow to cut print time per item, the tools that can help, and the mistakes to avoid.

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

Print time per item usually falls when fewer prints fail, when several parts share one bed, and when slicer settings match the printer and material. The steps below cover these points, and the tools section lists options for each.

What you need before you start

Before you change any setting, make a clear list of what you sell. Note the parts you print most often, the material each one uses, and how long each print takes now. The goal is a lower time per item, so you need a starting number to compare against.

Keep a working slicer profile for your printer, since every later change builds on it. Have a test print of your most common part ready, so you can check that a faster setting still gives a part that looks right and matches your listing photos.

Make sure the build plate is clean and the first layer sticks. A failed print costs more time than most settings can save. Keep a simple log of each print with its settings, its time, and its result. Over several weeks, the log shows which change helped and which did not.

Finally, know what your buyers expect from each item, so a shorter print does not lower the finish they paid for. Write the numbers in one place and review them once a week.

Step by step

Record the current time per item. Time one full print of each part you sell, including warm-up and cooling, so you have a baseline.
Fix failed prints first. A print that fails halfway wastes the whole run. Check bed leveling, the first layer, and the filament before you tune speed.
Group parts that share a material and a similar height. Arrange several copies on one bed so one run makes more items. Leave enough space between parts that they do not touch while printing.
Set the layer height to the thickest value that still meets your finish. Thicker layers finish faster. Test a wider layer height on a sample and compare its surface with your listing photos.
Raise speed in small steps. Increase print speed a little at a time, and check each print for ringing, weak walls, and skipped layers before going higher.
Reduce infill only where strength does not matter to the buyer. Keep outer walls and top layers solid enough for the finish.
Use supports only where they are needed. Orient each part so it needs little or no support, because removing supports takes time after the print.
Compare the new time with the baseline. Use your log to check whether each change cut the time per item without raising the failure rate. Keep the changes that help and undo the rest.

Tools that can do it

Several kinds of tool can help with this job. Slicer settings, batch layouts, and test prints each do part of the work, and the options below cover different parts of it.

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 whether a part can be made in a mould (the kind of checking done before plastic is poured into a metal mould) 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, a separate company that hosts websites. ^[1]

The ironing helper works out ironing settings for your printer, material and finish, and exports a ready 3MF file. ^[1] The test plate tool makes a 9-pad or 16-pad test plate around your settings, and you mark each pad as worked or not. ^[1] Ironing is a separate step from print speed, so use these tools for finish settings and check the time they add. For an uploaded Bambu or Orca project, the tool adds per-object ironing settings and keeps the rest of the file unchanged. ^[1]

It also lays parts out in a box and designs a 3D-printable foam tray and top pad that each part lifts straight out of. This one helps with packing finished items rather than printing them faster. ^[1] It runs only in your browser, and signing in with Connections lets your settings, recent test plates and print results follow you to every computer. ^[1]

A slicer is the program that prepares a model for printing, and most settings that change print time live there. Check its speed, layer height, infill, and support settings against the steps above.

Frequently asked questions

How can Etsy print sellers reduce print time per item?

Start by timing each part you sell so you have a baseline. Fix failed prints first, because a failed run wastes the full print time. Then group parts on one bed, lower the layer height to the finest value that still meets your finish, and raise speed a little at a time. Check each change against your log before you keep it.

Does LunarWerx 3D Print reduce print time per item?

For it, the tool works out settings for your printer, material and finish and exports a ready 3MF file, a common project file format for 3D printing. ^[1] Check the tool's own page for any print time figure before you rely on it for speed. Time each print yourself, before and after any change, and keep the results in your log.

Is LunarWerx 3D Print free to use?

Yes, the tools are free to use. ^[1] It runs in a web browser, and you use it on its website, which is hosted on Cloudflare. ^[1] It runs only in your browser, and signing in with Connections lets your settings, recent test plates and print results follow you to every computer. ^[1]

Can Etsy print sellers batch several parts on one print?

Yes, when the parts share a material and a similar height, several copies can share one bed. Arrange them so none touch while printing, and check that the first layer sticks across the whole bed. Batching cuts the time per item, but a failed run now costs more, so fix first layer problems before you batch.

What should Etsy print sellers check before choosing a print time tool?

Check what the tool says it does for print speed, not only for ironing or packing. Confirm its fee and whether it runs in a browser or on your computer. Test it on one part you already know, and compare the print time with your log. Keep the tool only if it saves time without raising your failure rate.

The tools are free to use. ^[1]
