3D Printing

The 3D printing room holds the makerspace's filament (FDM) printers, their AMS units, two filament dryers in the hallway, and a resin printer.

Course required. You must read the course and pass its quiz before you print on your own.

Module 1 lets you print ordinary PLA on the four upper-row X2Ds, one spool at a time.

Module 2 covers the rest of the filament printing.

Start here: Filament 3D Printing.

Resin printing has its own, separate authorization.

Floor plan of the hallway and the printing room. In the hallway, the filament shelves and the two dryers. In the room, the build-plate rack just inside, the X2D rack and the two H2S printers along one wall, the wooden shelf and resin cabinet at the far end, and the wall computer, tools and nametag rack opposite the printers

What is in the room

View along the Bambu printer rack, with eight X2D printers in two rows and the two H2S printers at the far end

Machine	Number	Names	For
Bambu Lab X2D	8, in two rows of four	Upper row, left to right: Döderhultarn, Eldh, Milles, Saint Phalle. Lower row: Calder, Giacometti, Koons, Kusama.	Everyday printing. Upper row: beginners and PLA. Lower row: more materials.
Bambu Lab H2S	2	Michelangelo, Picasso	Large prints, only when you need the size
Filament dryers	2	Sunlu S4, Royal dryer	Drying filament before you print
Prusa SL1S Speed and CW1S	1 and 1		Resin printing. Not covered here.

Each printer's name label matches its name in Bambu Studio.

Who may use it

When you have passed	You may
Module 1	Print ordinary PLA and Bambu PLA Silk+, one spool at a time, on the four upper-row X2Ds
Module 2 (after Module 1)	Use the lower-row X2Ds and the H2Ss, more materials, support material and several colours, the dryers, and the 0.8 mm hotend on an H2S
The Resin 3D Printing course	Use the resin printer

Before your first job: pass the Module 1 quiz, put your member label on your spools, and print your own nametag (first-print_circular-name-tag.stl). The nametag is your first job, and the only print that may run without one.

Everyone takes the course, including long-time members and people who print at home: most of it is about this room. There are no locked doors; the room works because members follow the rules.

Finding your way around

The floor plan above shows where everything is.

In the hallway: the filament shelves (spools taken off printers, and free filament; not personal storage) and the two dryers.
Build-plate rack: just inside the door. Finished prints wait here on their plate, and you take a plate from here.
Pegboards: small tools you may use, if you know how, spare scraper blades, and the Bambu Lab Liquid Glue.
Nametag rack and wall computer: on the same wall as the pegboards.
Wall fan above the H2S printers: you may switch it on.
Steel cabinet: the resin equipment. Uncured resin never leaves it.
Sink for washing plates: in the wet room, with dish soap.
Member booth: prints your nametag and spool labels.
Purge waste ("poop") runs down chutes into collection boxes, under the X2D rack and inside each H2S stand. They are emptied on community work days. If your job made a lot of waste, empty the box yourself, into the ordinary rubbish.

Filament

Buy your own, from anywhere, as long as it follows the material and spool rules. The member shop sells some Bambu Lab PLA: https://medlem.makerspace.se/shop/#category13. Bambu Lab filament is recommended while you are new: the AMS reads its RFID tag, and the settings are tuned for it.
Only moulded plastic spools, and only materials on the allow-list (Allowed materials). Not on the list means not allowed yet; ask in #3D-Skrivare to get something tested and added.
Keep your filament in your member box, each spool sealed in a bag (an IKEA ISTAD 4.5 L or 6 L zip-lock bag fits one well).
Took out someone else's spool? Put it in the shelf section marked "This week." The signs move one step every Sunday; whoever does it replies to the Slack reminder first.
Free filament has a FREE sticker over the owner's name, and stays in the room. ROOM DEV. spools belong to the room developers: leave them alone.
Glue and the shared build plates are paid for by the makerspace.

Computers, files and the network

The computers are shared, with one account. Nothing on them is private, so keep your own copies.
Each printer has its own USB drive. Take it out only to copy your file, then put it straight back. It never leaves the makerspace.
Your own USB drive is fine too. Once your print has started, take it out and put the printer's drive back. The printer has already copied the file, so the print carries on.
Never change the installed Bambu Studio profiles. Save your own settings under a clear name instead.
LAN mode only. Never change a printer's network settings, or connect a printer or camera to Bambu Cloud or the internet.

The most important rules

This is the short version. The full lists are in the course (Module 1 — Rules summary, Module 2 — Rules summary).

Pass the course first. Label your spools, and print your own nametag as your first job.
One printer at a time, first come, first served.
Nametag on when you start loading filament, off when your print is out. It must show your member number and name, like the member-booth label; a tag with less counts as no nametag.
Only allow-listed materials, on moulded plastic spools.
Filament goes through the AMS, with the tubes as they are. No rerouting, no external spool holders or splitters, no pushing it by hand.
Washing plates: warm water and dish soap. Never hand soap or acetone, and no IPA on SuperTack.
Plastic scrapers only.
Glue: only Bambu Liquid Glue, only on Textured PEI, and always for PETG.
Auto Bed Leveling stays on Auto, never Off.
Watch the whole first layer. After that you may leave, even overnight.
Hot nozzle, hot bed, fast print head. Let things cool, and never reach into a printer whose job isn't finished.
Leave the printer empty: plate in the rack, AMS empty, nametag off, inside vacuumed. Take your print with you.
Bin full? Take it out.
H2S only when your job needs its size.
Fire or electrical fault: deal with the danger first. Then, if it's safe, switch off, unplug, and tell us in Slack.

When something goes wrong

Fire, smoke or an electrical fault: deal with the danger first. Warn the people around you, get out and call 112, and use the nearest fire extinguisher only if you can do it safely. Then, if it is safe, switch the printer off, unplug it, and tell us in Slack.
Everything else: post in #3D-Skrivare. If it is urgent, tag @roomdev-3d.
A printer you can't fix: report it, and put a red Out of order! Reported on Slack tag from the pegboard on it. Never use a printer with a red tag.
Someone's print has obviously failed? Anyone may stop it. Tag the owner in #3D-Skrivare, without a photo, and leave the print on its plate in the rack. Run Unload before you take their spool out.
Fixing things yourself: see each machine's "Problems and fixes" page. Nothing that needs screws out or wires off without asking in Slack first.

Tell us when something breaks. The makerspace would rather teach than punish.
