How to queue prints across many printers in a print farm

Q: Is LunarWerx 3D Print free for print farms?

The tools are free to use. Whether a print farm needs anything beyond the browser tools depends on its own printers and workflow. The information published for LunarWerx 3D Print does not describe extra services, so check the site for anything beyond the free tools before you plan a workflow around it.

A tool-neutral guide for print farm operators on queuing prints across many printers, with steps, tool options and common mistakes.

Queuing prints across many printers means keeping one list of jobs, matching each job to a free printer that has the right material and enough build space, and checking each finished part before the next job is sent.

What you need before you start

Before you queue prints across many printers, have each printer's status visible in one place, whether that is a shared sheet, a dashboard or a simple list. Note each printer's build volume, the materials it runs and its nozzle and bed type, because a job that fits one machine may not fit another. Keep the sliced files for every part in a folder your team can reach, and name them so anyone can tell the part, material and settings at a glance.

Keep a record of print times and failures for each printer, since that record shows which machine should take the next long job. Calibrate the printers to the same standard, so a part printed on one unit matches the same part printed on another. Decide who may start, pause and cancel a job, because a queue with no owner drifts quickly. A shared sheet for recording results is enough to begin.

Step by step

List every job with its file, material, quantity and deadline.
Sort the jobs by deadline, then by how well each one fits the build volume and material of the printers you have.
Assign each job to a printer that is free, loaded with the right material and has enough build space for the part.
Check each sliced file against the settings of the printer it is sent to, because a file prepared for one setup can fail on another.
Send the job, then record the printer, start time and file name in your queue record.
When a job finishes, inspect the part, note any fault, and mark the printer free or flag it for maintenance.
Re-queue any failed part on the next free printer that suits it, and review the whole queue at set times each day.

Tools that can do 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 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]

Its ironing helper works out 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]

Other queue and farm software is not covered by the facts on this page, so this guide does not say what those tools do or what they cost. Check each tool's own page before you choose.

Things to check before you choose: ask whether a tool sends a job to a chosen printer and reports when it finishes, how it handles printers that run different materials, and whether it keeps a record of each printer's jobs and failures. Ask also whether LunarWerx 3D Print sends jobs to several printers, since the information published for it does not say whether it does.

Common mistakes to avoid

Sending a file prepared for one printer to another is a common mistake. Settings that suit one machine can fail on a different one, so check the file against the printer it is going to.

Loading a job onto a printer with the wrong material wastes time and filament. Check the material before each job is sent.

Letting a failed part sit unnoticed is another mistake. A printer that stalls for hours holds up every job waiting behind it, so review the queue at set times and act on faults as they appear.

Running a queue with no owner causes jobs to be duplicated or dropped. Name one person who answers for the queue.

Skipping the record of print times and failures makes it hard to see which printer is reliable. Keep the record from the first day.

Frequently asked questions

How do you queue prints across many printers in a print farm?

Keep one list of jobs with each file, material and deadline, then match every job to a free printer that holds the right material and has build space for the part. Check each sliced file against the settings of the printer it is sent to, record the start time and printer, and inspect each finished part. Review the queue at set times each day so a stalled printer or failed part is caught early, and re-queue failures on the next suitable printer.

Can LunarWerx 3D Print queue prints across several printers?

The information published for LunarWerx 3D Print covers ironing settings, injection moulding checks, foam insert design, fixing faces on STL files and sign-in that keeps your settings and print results with your account, and it does not say whether it sends jobs to several printers. Check that directly on the tool's website before you rely on it for that. You use it on its website, which is hosted on Cloudflare. ^[1]

What should a print farm check in queue software before buying?

Check whether the software sends a job to a chosen printer and reports when it finishes, how it handles printers that run different materials, and whether it keeps a record of each printer's jobs and failures. Ask what each tool costs, and whether that cost is published on its own page. Test the process with a small batch across two or three printers before committing the whole farm to it.

How do you keep a print farm queue from falling behind?

Assign one person to own the queue and have them review it at set times each day. Flag any printer that has stalled or failed a part, and move its waiting jobs to a free printer that suits them. Keep a simple record of print times and failures so the next long job goes to the machine that has been most reliable.

The tools are free to use. ^[1]
