👋 Introduction to 3D Printing at the Idea Lab
In this section, Trevor introduces himself as the facilitator at the Idea Lab and explains the goal of the video: to teach the basics of 3D printing using the Prusa Mark III machine. After watching the video, completing an online quiz, and passing an in-person practical test, participants will earn the 3D Printing Basics patch. The video covers safety guidelines, such as avoiding contact with the heated build plate and extruder, which can reach over 200°C, as well as operational rules like ensuring a facilitator is present during printing. Tools, tickets, and cleaning supplies can be found in specific locations within the lab.
🧰 Using the Tools and Filaments for 3D Printing
Trevor explains how to prepare for using the 3D printer by wiping down the build plate with a provided wipe and safely disposing of it after use. He also mentions the process for changing filaments if they run low and advises asking a facilitator for help if all filaments are empty. Participants must log into OctoPrint to start their printing session, upload their file, and slice it using the slicer settings. He recommends not changing the default settings, except for specific options like removing supports, before proceeding with the print.
🖨️ Monitoring and Starting the Print
This part focuses on monitoring the 3D printing process. After uploading and slicing the file, the machine will automatically begin printing. Users can monitor the printer’s status, including heating progress and the current layer of the print, through the OctoPrint interface. Trevor advises calling a facilitator to check on the print once the file is successfully sliced. The section also covers filling out a 3D printing ticket, which includes details like the user’s name, project type, contact information, file name, and the specific printer being used.
🛠️ Completing the Print and Handling the Build Plate
Trevor explains how to remove the completed print by lifting the flexible build plate and carefully taking off the print, including any excess test lines. He advises aligning the build plate back into position after removal. Participants can access tools to remove any supports from their print, ensuring the cleanup process is done gently over a garbage can to avoid damaging the print.
♻️ Unloading and Loading Filament
This section provides detailed instructions for unloading and loading filament. To unload filament, users must select the unload option, wait for the printer to heat to 215°C, and press the knob to retract the filament. Trevor explains how to keep the filament spool tight by threading it through a hole to avoid tangling. To load new filament, users should insert it into the top of the machine, which will automatically grab and extrude the material. After confirming successful extrusion on the screen, the printer is ready for the next print.

hello i'm trevor i'm the facilitator
here at the idea lab
for 3d printing and today we're going to
be going over the basics of 3d printing
with the prusa mark iii after completing
this video
the online quiz and in person practical
you will be receiving the 3d printing
basics patch here at the idea lab
where you can use the octoprint and
prusa machines
these machines print with a diameter of
1.75 millimeters using pla
filament these machines can get to a
temperature of over 200 degrees celsius
and the build plate is 25 centimeters by
20 centimeters
with a max height of 20 centimeters as
well
one of the main rules regarding safety
here on the 3d printers is to not touch
the build plate or extruder
when the printers just start warming up
or currently printing or just finished
because they can be considered
dangerously hot
here are the 3d printing rules you can
find them here or on the website
the main rules are that a facilitator
must be in the room when printing
and you must have a 3d printing ticket
and you can only print when you have the
basics badge
here's where you can find the tools for
the 3d printers
you can find the 3d printing tickets
here as well which you must fill out and
have a facilitator sign
here you can find the wipes to clean off
the beds of the 3d printers
as well as the pliers and scrapers
when preparing the 3d printer for use
make sure to grab one of the wipes from
the tool bin
and simply open up the paper
take out the wipe and wipe down the
build plate
when you're done make sure to throw out
the wipe
here is where you can find the filaments
you can
change out the filaments if they're
running low for your print
if all the filaments are unavailable or
empty
please ask a facilitator for help
once you log into octoprint this is a
screen you'll see
on the top is the state of the printer
right in front
is the temperature currently and when
you click on these set tabs at the top
you can see the different settings and
right here is the slicer which is where
you would go first
once here you can upload your file go to
the bottom corner click upload
find your file open it
wait for it to load in
all right once it's loaded in here it is
on the finder
you can see it here you can right click
to move around
scroll down here's the settings you can
see the
current settings after slicing you want
to do is
start printing make sure this is the
profile
here's the settings you can change i
suggest not changing any of them
for this one i'll take off supports
and once everything's ready you can
click slice it
and it will start printing automatically
all right once it's done slicing it'll
start printing automatically
here you can see what's currently
happening
right now it's heating up which you can
see at the temperature at the top here
it'll take a little while to do so and
once that's all ready you can go to the
g-code viewer and see the current layer
it's currently on
once you have successfully uh sliced
your file on
octoprint you can call over facilitator
to check on it
once everything is complete there you
can grab a 3d printing ticket
and once you grab the ticket you can
fill it out so first at the top is your
name
and then the date
and here is where you can choose what
type of project it is personal
for a class or something else
and here's the contact you could put a
phone number or email
and here's where you put a file name
and which printer you're using so i'll
put
prusa and then i'll put the number of
the printer it is
so three and then this is where i sign
or facilitator in charge and once that's
all done
you can put your ticket in front of the
printer
and you can start your print
all right when the print is finished
simply lift up the
build plate flex the bed so that the
print comes off
and take off the test line at the bottom
and simply line it back in place so that
everything is perfectly lined up
when your print is finished simply come
over to the tool section
you can take any tools that you need to
remove any supports
that may have formed when printing when
removing supports make sure to do it
over a garbage can
and be super gentle not to break the
print itself
to unload filament simply click the
button
scroll down to unload filament
hit pla which is 215 degrees celsius
and wait for it to heat up
all right once you hear the beep press
the
knob to unload and then the filament
will
slowly retract and once it does so just
simply grab it
once you have successfully unloaded the
filament you can pull it
through the pulley and then keep it
tight when you roll it back
onto the spool
once it reaches the end push it through
one of the holes at the bottom to keep
it tight
you should be ready to go to load the
next filament
feed the filament through the pulley
after unloading filament the printer
should still be heated up
and to load the filament simply insert
it into the top
and the machine will grab it
automatically it will now be extruding
from the bottom
and make sure when it's done click yes
the film is extruded on the screen
and you should be good to go
