General Information

The Bambu Labs 3D Printer can be found inside the Clean Room. 

The purpose of this page is to give a more in-depth look at the Bambu 3D Printer.

If you have any issues with Clean Room equipment, the slack channels associated with this space include: #general, ##general, #shop-3d-printing, and #shop-laser.

Filament

Material - PLA, PLA+, PETG
  • Please let us know if you'll be using PETG, or unlisted materials. A cold pull will need to be performed after use
    • A cold pull involves clearing out the hotter melting filament before using a colder melting filament. PLA is the most common used filament at the space, and has the lowest melting temp - any debris left after a PETG or similar print will not melt under PLA hotend temperatures. This generally requires preheating the hotend to the temp of the higher melting point material, passing PLA filament through, cooling the hot end below the PLA melt temp (ideally around 160c) and physically pulling out the filament.
    • This should remove extra filament that was remaining in the hot end before the procedure
    • This may need to be performed multiple times
    • If you are not comfortable doing this, please stick with PLA, or coordinate with Jess or another experienced printer in order to load and unload your filament
      • That said, please get comfortable doing this. I'm happy to help you the first time, or if there is an unexpected clog, but advanced filaments require you to be competent in this level of printer maintenance
Filament Size - 1.75mm
Brand - Most PLA and PETG available these days is of adequate quality. Amazonbasics, SUNLU, Hatchbox, Overture are my most purchased filaments
    • IIID Max is a great option if you're buying a lot. Free shipping and the lowest per kg prices right now
    • PushPlastic is my preferred vendor for large rolls. The filament spool holder I have available for the cr-10 max supports their rolls. Be wary, as the hole size for various vendors for 5kg+ spools can vary drastically.

Recommended 3D Modeling Software

  • TinkerCAD- Browser based, cloud-based, approachable for makers of all ages
  • Fusion 360- Cloud-based parametric 3d modeling software. Collaborative, powerful, free license available
  • LuBan- Has a number of fun features for scaling models to any size, lithographs, box making, extrusion, etc. We have a license for this software on-site, available on the PC located in the 3d Printing Area

Using the printer

Loading / Unloading filament (side spool)

https://wiki.bambulab.com/en/x1/manual/loading-filament

  • The filament tab is the easiest way to load filament, but the instructions above still work.
    • You can configure your filament type, and then select load or unload to begin the process
    • The printer will preheat to the required temperature (usually 250 for most filament), and prompt the user to insert the filament into the PTFE tube
    • Once you've pushed it into the extruder, it will grab and feed the filament into the hotend
    • You will be prompted to check if the filament fed properly (you should see old filament coming out of the nozzle). Hit ok, and it will further purge the nozzle of any remaining previous filament

Installing a print surface

  • We have multiple build plates available
    • Cool Plate - A polycarbonate sticker. PLA only (despite what the plate says). Sticks really, really well. MUST have a layer of gluestick on it, or it can damage the surface from over-adhesion
    • Engineering Plate - original surface we had for non-PLA. Works with petg, abs, nylon, tpu, etc. Must have some glue stick on it to work well at all.
    • Smooth PEI (high temp plate) - great all-around surface, works well with or without gluestick. Smooth surface on bottom.
    • Textured PEI - works with many filaments without glue, not as reliable for really big, really tall or really long print times.
  • If it looks particularly gummed up with glue stick, its probably a great time for you to clean it!
    • Warm water, some hand soap and a sponge is everything needed to wipe the glue stick off
    • Let it completely dry, put a fresh, minimal layer of glue stick on (if required) and continue
  • When installing, make sure it lays between the two indexing tabs on either side of the bed
    • If its sticking up, you've installed it wrong!
  • Make sure you configure Bambu Studio to the correct build plate before sending the file over
