3D Printing

Four Bambu Lab printers in the 3D area. Shop filament is Bambu PLA only. Slice on the two workstations next to the printers (Bambu Studio). Complete 3D Printer Orientation before using any of these machines.

Printers

•       Janet — Bambu A1 with AMS. General use and multi-color.

•       Bambi — Bambu A1 with AMS. General use and multi-color.

•       Xorp — Bambu A1 Mini. Small, fast, single-color.

•       Prints Charming — Bambu P1S. Enclosed. Good for longer PLA parts.

How to run it

1.    Check Slack #3d_printers. If a machine is free, post which printer you are using and about how long the print will run.

2.    On a slicing workstation, open Bambu Studio. Import your .stl or .3mf. Pick the named printer you will use (Janet, Bambi, Xorp, or Prints Charming). Filament: Bambu PLA. Use the default PLA preset. Match the AMS slot to the color in the machine if you are using AMS.

3.    Slice. Look at the preview. If walls are missing, supports look wrong, or the part hangs off the plate, fix it or ask. Do not send a bad slice.

4.    Inspect the printer. No leftover part on the bed, no spaghetti, no note on the machine. If someone else’s finished print is still on the plate, leave it and use another printer, or contact that member. Do not dump their part.

5.    Confirm Bambu PLA is loaded. If you need a different color, take an empty reusable spool from the cabinet, load a new refill onto that empty spool, and put the old partial spool back assembled. Never split a spool that still has filament on it. Check the cabinet for that color before you open a new refill.

6.    Wipe the plate with a dry paper towel. If the last prints would not stick, wash the plate with a drop of dish soap and water, rinse, and dry it fully.

7.    Send the job from Studio or start it on the printer. Stay until the first layer is down. If it smears, lifts, or piles up, cancel, clean the plate, and start over.

8.    When the print is done, let the plate cool. Flex the plate or use a plastic scraper. Do not use a metal scraper. Throw failed prints and purge in the scrap bin. Wipe the plate. Close AMS and printer doors. Leave the station ready.

Before you print

•       Orientation is done. You are only checked out for these four Bambu printers.

•       Bambu PLA only. No PETG, ABS, ASA, TPU, nylon, carbon-filled, or third-party filament.

•       Use the shop cabinet filament. Do not bring mystery rolls from home.

•       Printer is idle and the bed is clear.

•       Correct printer profile in Studio. Default PLA preset. Do not change speeds or temperatures for other members.

Safety

•       Hotend and bed are hot. Hands off until they cool.

•       Stay clear of the moving bed and toolhead while it is homing or printing.

•       Stay for the first layer. That is the checkout rule, not a suggestion.

•       No resin printers at LCS. Do not set one up in the 3D area.

•       Do not sand printed parts at the printers. Dust in the mechanics.

Filament

In the machines and the cabinet: Bambu PLA. Partial spools stay on their reusable hubs, halves locked. Empty hubs are for new refills only. Keep the paper color label on the rim of the spool. If a spool is split with filament still on it, snap it back together or tell a lead.

Shared shop rules

•       Post in #3d_printers when you start. Do not park a multi-day print without a lead saying yes.

•       Ask before you touch another member’s finished part on the bed.

•       Do not load anything but Bambu PLA.

•       Do not tune profiles, flash firmware, or leave a custom preset as the default.

•       Report a clog, a chewed AMS PTFE, a gouged plate, or a printer that will not read RFID.

•       Need PETG, TPU, or something else? Ask in Slack. Some members will print that at home. Not on these four machines.

•       Need a model? Printables or MakerWorld. CAD help is a Slack question, not part of this page.
