3D Printer (Generic FDM)
Video watched, quiz taken, any questions?
Identify and describe control axes, changing filament, and cleaning print surface
Cleaning the bed (for the first print of the day)
Putty knife to scrape away chunks
Lightly sand with sandpaper (grit #)
Paper towel with isopropyl
Changing filament
Pre-heat machine (215)
Cut filament near spool (at angle)
Remove old spool - keep slight tension on filament!
Filament end should be secured on spool itself, inserted into the printer, or held in your hand - loose filament WILL tangle!
Remove old filament from extruder,
Move tension spring lever on top and pull filament from extruder motor
Adding new filament (only PLA)
Select desired color from available filaments
If a new roll is opened, write down the color on the To Purchase Clipboard
Feed new filament through extruder/tube until desired color is extruded
On Minis, tension lever must be depressed
Printing from Octopi
Go to http://octopi#.makehaven, where # is the number printer you’re using (each printer is labeled on the front)
If printer state is Offline
Click the grey Connect button, printer should now say “State: Operational”
On the lower left hand side are the Folders and Files, create a folder with your name, then upload said folder
Click the Upload button at the bottom
Select your STL file, which will load into slicer automatically
Using the slicer controls: Rotate, scale, remove, duplicate
After orienting model in slicer, go to General tab
Change to “After Slicing: Select for Printing”
On Basic tab:
Change “Fill Density” to desired percentage (suggested value of 15%)
Change “Support Type” if supports are required
Build plate: only supports where model is over buildplate
Everywhere: adds supports anywhere where there is a 45° or greater overhang
Make sure extruder temp is 215 degrees and bed is 60
On Advanced tab:
Change adhesion from “None” to “Brim” as default, and to “Raft” only if you’re having adhesion problems
Click “Slice”
On left side click blue Print button
Print Process
Keep note of “Filament (tool 0)”; each member is allocated 30 meters per day. If your prints exceed this, please pay $0.10 per meter at makehaven.org/store, or in the cash box on the wall near the 3D printers
Put a Name and Date Label (printed from the label machine) on the printer so another user can put your print on the Finished Shelf with this label, or so that if the print fails another user can tell you on Slack
Removing the print: use a putty knife with the beveled side up at a very shallow angle, to avoid gouging the print surface. Prints are easier to remove once the bed has cooled below 50°C
If you experience problems that you cannot fix while printing, replace the green check mark with a red X. If able, leave a note on the whiteboard of the problem, and post on Slack
Cleaning up tool
Please make sure any bits of filament are thrown in the trash
Feel free to talk about the following:
Bed levelling
Clearing clogged nozzles

Build & Badge: 3D Printers

Ready to bring your designs to life with 3D printing? Join us for this group badging event, designed to help members confidently complete their in-person check-out on MakeHaven’s 3D printers. Together, we’ll walk through the check-out process by creating a small, personalized print. Working in a group makes the experience more approachable and provides an opportunity to connect with fellow makers!
