you might know me as the small computer guy or the ubiquity fairy or whatever
you want to know me as but what you probably don't know me as is a dude that
likes 3D printers I have a prusa mark 4S at home and that thing freaking rips
it's the most reliable printer I've ever had and the only thing I've ever wanted
out of it is an enclosure I have this stupid like weed grow tent thing that's
honestly bigger than this box but today prussa is solving that problem for me
maybe this is the prusa Core 1 it is
their new core XY printer which if
you're unfamiliar and you might be familiar with prusa's other uh printers
which are the bed Slinger style as in the build plate actually moves back and
forth for that axess this one not unlike their prusa XL the bed only moves up and
down and the print head is what moves back and forth which gives them a bit of
an advantage uh specifically in terms of space you don't have to move the giant
build plate back and forth so we should be getting a bigger build area in the
same amount of space and also an enclosure they include gummy bears we've
got a sheet with whatever stuff's in here a steel sheet core one I like the
new design though it's it's pretty this is a smooth Pei sheet so this is
something you would use with like pla filament um usually not with filaments
that are stickier and might get stuck enough that you would damage the plate
trying to take it off we've got a power cable this thing got wared in
shipping there's a screw Glen
what's this oh it comes with a roll of filament uh prusa pla Galaxy black this
is really pretty stuff despite the loose screw it doesn't have any obvious damage
now this thing is built around a steel exoskeleton as they call it so in theory
it should be incredibly strong and I mean it got bonked pretty hard and it
still looks like a big old rectangle
there's the screen we've got a number two Phillips screwdriver a little pair
of pliers which is always nice and then the various Allen keys and wrenches you
need to service this thing if you're not familiar with prusa's a big selling
point for them they make and sell parts for basically any piece of this machine
and not only that you can modify them which is super cool like thanks
Belle Belle Belle
Bell now one curious change I've started
to notice in prusa's uh manufacturing it
used to be that like every single part of your printer that was plastic was 3D
printed well now they've started doing injection molding for the screens which
it does look nicer but it also means that this part is less replaceable I
guess I mean I'm sure they'll probably give you a 3D printable version of this
I mean this is basically the same screen cover they've been using for ages it
feels a little bit icky let's try and click it on here speed that through
there there we go boom boom attached we've got other build plates so there's
all three of them smooth satin and textured and if you're unsure of which
one you should use at the certain filament uh they actually have a pretty good like materials guide on their
website that tells you which one is best if you're just printing with pla all the
time the uh smooth one it comes with will be just fine this is the camera
module couple extra magnets these don't come in the box but because it's steel
you can print some cool accessories and then nylon ribbits oh that's what this
is held in is a nylon rivet this printer uses PR's extruder which is the fancy
word for extruder and you can see it right here and it has a high flow nozzle
it's kind of a cool piece of technology inside the nozzle you have like the
stream of plastic comes in and then it splits into multiple paths inside to
like better distribute the heat load I guess and allow the nozzle to flow
faster than just a normal one that's exactly what I was hoping for
let's install our little camera thingy there's a USBC
cable and then is this just magnetic now that it's sitting there properly it
magnets in there pretty good and all this hard work has really got me feeling
like gummy bears here I'll give you guys one too and you can have the segue to
our sponsor vessie ah February that time
of year where you feel like yeah the weather's going to be clearing up but
then no it starts snowing in Florida well with vessie and their dry sock
guarantee it doesn't matter you'll be ready for any weather any time of year
so maybe pick up a pair of their weekend chelseas they combined yearr round Style
with a hight traction Rubber Sole and a cozy fleece lining that keeps your feet
warm and dry all while still letting them breathe so you don't have to worry
about knocking anybody out when you go to take them off go to v.com sshort
circuit to get an automatic 15% off your first purchase we going to have that
linked down below like I mentioned before the enclosure is one of the
biggest changes here it's just like a lot of the other 3D printers in the
market now uh their previous printers you would have to buy or build a
separate enclosure that made them like way bigger but this one nice and Compact
and includes an enclosure and part of that is this door which is actually
pretty cool and it does open and lock in a few different places and you can
actually flip the hinges to the other side which is pretty cool there is also
a vent on the top here you can see and this vent is important when you're
printing pla or PG because uh despite an
enclosure being helpful for like keeping dust down and whatnot and and regulating
the temperature so that if somebody opens an exterior door you don't get get
a big rush of cold air PLA and petg don't really like it when it gets really
hot uh so you're better off keeping this open to keep the temperature down but
then you still get the benefits of an enclosure on the outside they've got these cool like cutout things uh which
are perfect for this side like you can see with the included thing putting your
spool of filament and then the filament feed you can see the tube is poking out
right there so you put your spool on feed your filament in there and it doesn't take up any additional space on
the back or the side of the printer it is INS set and and then you also have
the same thing on the other side in the future once they have the multimaterial
add-on kit available I guess you could probably put another spool here and that
could be two filaments and maybe put three more on the top I don't know we'll
have to see what that actually looks like once it comes out the back we can see the power cable here we've got an
Ethernet Jack NFC which is used for
pairing Wi-Fi more easily if you download the app you can then like NFC
the Wi-Fi credentials to the printer which is a nice add-on and then they've got this chunk here which is where the
Wi-Fi module is located it's inside of here and then there's a header here
which at least on the mark 4S is used to connect an accelerometer uh I know that
they also have a gpio hacker board thing where you can use the printer to send uh
signals to other things what that is it's kind of up to you you could use it
to like trigger a DSLR camera if you're doing a time lapse or something like
that and then there's a USBC Port which I don't actually know what is for power
button power plug which we're going to need now a lot of this printer is very
similar to the previous prusa bed Slinger style printers like the mark 4S
so you have your z-axis screws here um
there's three now which is interesting this axis I think it's the xaxis my
brain always screws this up uh it's a linear rail now instead of two rods I
don't know why they've made this change but that's what it is now uh and then
there is two sets of steppers for the Y
AIS now instead of just one Lighthouse Beni 17 hours that might be a little too
much sauce fast forward some amount of time the printer is actually out now so
we've got public access to the profiles and we can go through this like you
would at home if you were to buy one of these so I've got prusa slicer
downloaded on this lovely MacBook here which is not mine thank you Jake Bell for letting me borrow it now it's worth
noting you don't have to log in to use this printer at all you can use this
printer with any slicer that's compatible with it you can use it
without having to log in without having to connect to the internet you just take
the USB stick out plug it into your laptop which I guess we're not doing
because it's a Macbook and it only has type-c plug it back in and print but I'm
going to use the account anyways because I think that this is how most people
will do it and it does allow us to show off some of the cool online features
that it does have there's lots of places you can find stuff to print thing of ours printables um maker world I usually
like to use printables which is P's own service because it's just got nice
interface good quality models there's lots of fun stuff on the main page which
honestly is probably the main thing for me speaking of cool models on the front
page I scrolled past this M1 Pro Car Kit
card that looks pretty sick and I think it's complicated enough with some
overhangs and stuff that this would be actually a good way to test this printer
so we're going to do this now what color
was there ever an orange Pro
car oh yeah okay I like red Red's a good
color they made a M1 in red did they not yeah they did hell yeah actually there
was even a pro car that was red perfect see you later orange lipstick red pla
you know if you've ever done 3D printing or looked into 3D printing you probably heard of pla pla is great uh because
it's really easy to print with it doesn't like to like stick to the nozzle
and gum it up it doesn't clog it doesn't really wear out the nozzles it's
dimensionally pretty stable the only thing it isn't uh is good at high
temperatures so if you're printing something for inside your car not going
to work unless you live somewhere where it's literally cold all year round I was
designing like a little phone mount for my car and printed like a test version
just to check the dimensions and stuff I printed it in LA and like a day of it
sitting out in like not that hot Vancouver weather it it was like drooped
way down it didn't even have a phone on it we're going to pick print pla I'm
going to change the infill uh the default grid is like fine when you're
just printing something that you just for looks or whatever but I pretty much
always use adaptive cubic which is
pretty much the same speed as the grid
pattern but it's three-dimensional so whatever you print is not exactly but
more equally strong in all Dimensions than the grid pattern which is like
across so vertically might not be as strong and the cool thing about the
Adaptive One is if there's big voids in your print like in the middle you see it
like it just leaves empty space there and puts the more structural stuff in
the parts that actually matter it's very cool okay I played around with it a
little bit more we're going to do 20% infill so a little bit less point two
layer height by default and then I have adaptive layer height enabled and I just
left it at the default told it adaptive and sliced it and it says 6 hours and 20
minutes so that should give us a pretty good balance of you know the tops of the
model being pretty smooth but it printing relatively quickly so prus
connect is their online Cloud platform I guess this allows you
to be like in a different place than your printer and as long as it's
connected to the internet and ready to go you can queue up prints from anywhere
so you can see the file transfer to prusa connect is already done and then
it needs to download to the printer which you can see hey downloading now
this is one of my pain points with this thing this is a 12 megab G-Code which is
on the larger side G-Code being like the file that tells the printer what to
print but as you can see the remaining time on this file transfer says almost
10 minutes now I don't know if it's actually going to take that long and
we're talking 12 megabytes I'm not not 12 gabes 12 megabytes the reason that
this is so slow is because they're using this like really crappy Wi-Fi module
that um it's pretty cheap and uh it actually does does the file transfer
over serial which is a bit of a limitation now I complained about this
to them because my home printer I have the same problem where the file
transfers are just excruciatingly slow
and apparently it has set a bit of a fire off at prusa so maybe by the time
you're watching this video they'll have released a new version I don't know
however if you use prusa connect they have this cool streaming feature where
the G-Code streams from P connect to the
printer so it can actually start before it's even done the transfer uh which
which is very cool kind of resolves some of the concerns I just brought up but if
you have an unreliable Wi-Fi connection and it cuts out partway I could
definitely see how it would cause some problems for you on a printer of this
Echelon I want 5 GHz Wi-Fi you're paying a lot of money it should be a little
better than this since we're printing pla we've got to open the little top
vents as per the instructions that allows cool air to come in 25 out of 20
so its Target is 20° which means the fans at the back are going to be running
constantly can I feel them to try to keep the chamber cooler oh I didn't
realize there's like LEDs here but what I do know is there's LEDs behind here
that's just to make it a little easier to see your print oh you know what it's
also for to make it easier to see with the camera right I forgot about that hey
you see look at that there's a camera it doesn't have like a time-lapse
mode or anything like that as far as I'm aware which I feel like it probably
should and the fact that it's a separate product in general is kind of weird at
this price point 1,200 $ should come with better wi-fi and uh a
camera by default it's not an expensive camera like how much does this thing
cost prusa okay so the camera is $40 does feel like it should just be
included now to be fair I I almost never use the camera on my mark 4S prusa
because it is so reliable I actually don't know if I've ever had a print
failure on it it's pretty high resolution it's like nice and sharp so
that's good at least I guess at this point let's just let this print and
we'll come back and see the results and let's take a look at our prints so I
ended up printing a couple more things and a couple different materials to try
things out um but this is the first
print with our variable layer height in pla it's not the cleanest thing ever I
don't know if the variable print height is the best thing ever and I think
there's just some wonkiness in this model in the back you can kind of see
you can kind of see there's some voids there on the overhangs but I mean it did
warn us about those to be honest the overhangs on the Wheel Es are not
perfect but they're pretty damn impressive for the amount of just like
free hanging plastic that's there and how thin that is and how aggressive of
an angle it is it looks pretty good but you can see hey the variable layer
height sometimes is obvious on the side you can see the spots right there this
is with the speed profile and and definitely not like tuned for maximum
quality or anything like that and to be fair I didn't dry the filament at all
ahead of time if you're new to 3D printing buy a filament dryer dry all
your filament it will make things so much easier because that one wasn't
perfect I decided to print it again in a different filament without variable
layer height aside from just on the top to smooth that out a little bit and with
a .15 height elsewhere and also with no
supports and like overall in terms of like print quality it seems to be
exactly as I would expect it's basically like a mark 4S and I guess I can
assemble a car hey look at that you can
see our first attempt at the wheels not bad second tempt looks a little bit
cleaner I did have a chance to dry this marble filament before we used it so I
think that that's definitely part of it and then it would be weird if we had red
tires so we also printed tires but these are out of a soft filament you can see
this got some squish I used duramic TPU
I mean TPU assuming that it's dry is fairly easy to print with because it's
so sticky it's not like it's going to peel
off of the build plate I didn't test the tolerances on using different materials
cuz some of them shrink a little differently than others stick it on there anyways nothing a little glue
couldn't fix I mean it it rolls but like
you might lose a tire now let's talk tricky filaments
because let's be honest the big draw of having an enclosure is being able to
print filaments that require like a heated environment because they're so
high temp that if you don't have it they will warp and uh warp they did this is
with print PC blend which is designed to be like an easier to print polycarbonate
um this is a material that prints at a very high temperature is traditionally
quite difficult to print with I left the filament in a heated dry box in between
these two prints for several hours and you can see on the left the results are
quite a bit better the second go around this is with the satin build plate and
it looked like it adhered pretty well at the start but this was like a 5 six hour
long print and eventually it did start to warp I tried to print them all in one
go and these are very tall and the
spaghetti happened so while having an enclosure is definitely nice uh for
printing more complicated Advanced filaments like this it's not a magic or
silver bullet but it does offer some other nice things uh I definitely
noticed that this printer is way quieter than the mark 4S I'm not sure how much
of that is because it's a core XY design and it's not like moving this giant bed
back and forth versus how much is from the fact that it's an enclosure I
imagine the enclosure is a big part of it because I was having problems with
the other model I tried a different little like clampy guy it's a little bit
smaller and this one printed pretty much
perfectly I tried the textured build plate and if you look at it it doesn't
look like it warped much at all maybe a
tiny tiny little bit on the first print I had everything on there and uh the
screw you can see there's a giant glob on there if you're doing Advanced
filaments like this highly recommend trying the uh hardened obsidian nozzles
that they sell uh you you can also get like fancier nozzles from other vendors
that work with these printers because the stock brass nozzles that come on
here are very sticky for certain Plastics especially polycarbonate and as
it builds up you're just going to have situations like this overall thoughts
then if you're willing to get DIY and um
I don't know the exact amount of time it will take to build a machine like this
because the DIY kits aren't out yet but when they are it's about $250 less
you're looking at 950 USD to buy the DIY
kit and if you want to compare to the mark 4S it's about $200 less uh
regardless of if you're doing DIY or buying pre-assembled you're getting
bigger build volume which is always nice you can print bigger stuff you're
getting a quieter printer one that takes up less space assuming you were going to
buy a mark 4S with an enclosure it's better than the marvs in a lot of ways
it still has some of the same issues like the Wi-Fi is not great it's not the
most beginner friendly like don't get me wrong I I can understand why people Buy
printers from like bamboo Labs for instance um they are very newbie
friendly you also have to consider the rest of the market price comparison wise
your other options x1c from bamboo Labs
the new creality is it K2 Pro I think is
what it's called they're all kind of in the same price bracket so if you were to go with the bamboo you have their AMS
system if you are looking for a multimaterial setup um which to be
honest the prusas they have their mm mu3 which is a multimaterial setup it can
only do five materials and is a lot more bulky than the uh the bamboo equivalent
and creality has a similar setup uh but
with way bigger build volume on the printer that's in the similar price
class as this so there's a lot of competition but if you go with a prusa
you're getting something that is repairable with parts that you can 3D
print yourself to replace if you need with a big Community behind them and a
lot of modding support even though this printer like came out a couple days ago
there's already accessories that they made first party like I saw this cool
door you can put on to make a dry box inside of here definitely recommend that
um and who knows what the community will develop I think it's pretty sick if
you're going to buy a mark 4S you should probably just buy this one instead if
you care about spending your money on something you can actually fix and
upgrade I didn't even mention that they're actually going to offer this as
an upgrade kit for the mark 4S for like 400 or 500 bucks us we'll put it on
screen however much it is it's not out yet but that's a pretty compelling upgrade if you want an enclosure I uh
I'm very very tempted personally prusa you still got some work
to do but I like this thing and I like you so get subscribed hit the like
button and let me know what you think about this prusa core one
