WEBVTT

00:00:00.040 --> 00:00:06.319
you might know me as the small computer guy or the ubiquity fairy or whatever

00:00:04.640 --> 00:00:10.800
you want to know me as but what you probably don't know me as is a dude that

00:00:08.200 --> 00:00:14.639
likes 3D printers I have a prusa mark 4S at home and that thing freaking rips

00:00:12.799 --> 00:00:20.600
it's the most reliable printer I've ever had and the only thing I've ever wanted

00:00:17.720 --> 00:00:26.240
out of it is an enclosure I have this stupid like weed grow tent thing that's

00:00:23.519 --> 00:00:32.000
honestly bigger than this box but today prussa is solving that problem for me

00:00:28.400 --> 00:00:35.239
maybe this is the prusa Core 1 it is

00:00:32.000 --> 00:00:36.399
their new core XY printer which if

00:00:35.239 --> 00:00:41.039
you're unfamiliar and you might be familiar with prusa's other uh printers

00:00:38.719 --> 00:00:44.760
which are the bed Slinger style as in the build plate actually moves back and

00:00:42.920 --> 00:00:49.280
forth for that axess this one not unlike their prusa XL the bed only moves up and

00:00:47.239 --> 00:00:53.160
down and the print head is what moves back and forth which gives them a bit of

00:00:50.760 --> 00:00:56.760
an advantage uh specifically in terms of space you don't have to move the giant

00:00:54.879 --> 00:01:00.559
build plate back and forth so we should be getting a bigger build area in the

00:00:58.559 --> 00:01:04.640
same amount of space and also an enclosure they include gummy bears we've

00:01:02.800 --> 00:01:10.360
got a sheet with whatever stuff's in here a steel sheet core one I like the

00:01:08.400 --> 00:01:13.880
new design though it's it's pretty this is a smooth Pei sheet so this is

00:01:12.200 --> 00:01:18.479
something you would use with like pla filament um usually not with filaments

00:01:16.320 --> 00:01:22.720
that are stickier and might get stuck enough that you would damage the plate

00:01:20.320 --> 00:01:31.600
trying to take it off we've got a power cable this thing got wared in

00:01:26.200 --> 00:01:31.600
shipping there's a screw Glen

00:01:33.640 --> 00:01:41.040
what's this oh it comes with a roll of filament uh prusa pla Galaxy black this

00:01:38.159 --> 00:01:46.880
is really pretty stuff despite the loose screw it doesn't have any obvious damage

00:01:44.479 --> 00:01:52.159
now this thing is built around a steel exoskeleton as they call it so in theory

00:01:49.840 --> 00:01:58.119
it should be incredibly strong and I mean it got bonked pretty hard and it

00:01:54.280 --> 00:02:00.320
still looks like a big old rectangle

00:01:58.119 --> 00:02:05.079
there's the screen we've got a number two Phillips screwdriver a little pair

00:02:02.799 --> 00:02:09.399
of pliers which is always nice and then the various Allen keys and wrenches you

00:02:07.240 --> 00:02:14.400
need to service this thing if you're not familiar with prusa's a big selling

00:02:11.560 --> 00:02:18.680
point for them they make and sell parts for basically any piece of this machine

00:02:16.599 --> 00:02:26.640
and not only that you can modify them which is super cool like thanks

00:02:21.599 --> 00:02:26.640
Belle Belle Belle

00:02:27.200 --> 00:02:33.519
Bell now one curious change I've started

00:02:30.239 --> 00:02:35.239
to notice in prusa's uh manufacturing it

00:02:33.519 --> 00:02:39.080
used to be that like every single part of your printer that was plastic was 3D

00:02:37.200 --> 00:02:43.959
printed well now they've started doing injection molding for the screens which

00:02:41.519 --> 00:02:47.920
it does look nicer but it also means that this part is less replaceable I

00:02:46.599 --> 00:02:51.800
guess I mean I'm sure they'll probably give you a 3D printable version of this

00:02:50.200 --> 00:02:56.239
I mean this is basically the same screen cover they've been using for ages it

00:02:53.680 --> 00:03:01.400
feels a little bit icky let's try and click it on here speed that through

00:02:58.800 --> 00:03:05.400
there there we go boom boom attached we've got other build plates so there's

00:03:02.959 --> 00:03:08.040
all three of them smooth satin and textured and if you're unsure of which

00:03:06.959 --> 00:03:13.239
one you should use at the certain filament uh they actually have a pretty good like materials guide on their

00:03:10.720 --> 00:03:16.519
website that tells you which one is best if you're just printing with pla all the

00:03:14.760 --> 00:03:21.040
time the uh smooth one it comes with will be just fine this is the camera

00:03:18.840 --> 00:03:26.360
module couple extra magnets these don't come in the box but because it's steel

00:03:23.440 --> 00:03:31.560
you can print some cool accessories and then nylon ribbits oh that's what this

00:03:29.200 --> 00:03:37.159
is held in is a nylon rivet this printer uses PR's extruder which is the fancy

00:03:34.480 --> 00:03:42.400
word for extruder and you can see it right here and it has a high flow nozzle

00:03:39.959 --> 00:03:46.360
it's kind of a cool piece of technology inside the nozzle you have like the

00:03:44.080 --> 00:03:51.560
stream of plastic comes in and then it splits into multiple paths inside to

00:03:48.879 --> 00:03:55.760
like better distribute the heat load I guess and allow the nozzle to flow

00:03:53.879 --> 00:04:00.239
faster than just a normal one that's exactly what I was hoping for

00:03:58.400 --> 00:04:04.599
let's install our little camera thingy there's a USBC

00:04:02.159 --> 00:04:08.000
cable and then is this just magnetic now that it's sitting there properly it

00:04:06.519 --> 00:04:11.159
magnets in there pretty good and all this hard work has really got me feeling

00:04:09.760 --> 00:04:15.959
like gummy bears here I'll give you guys one too and you can have the segue to

00:04:12.760 --> 00:04:17.880
our sponsor vessie ah February that time

00:04:15.959 --> 00:04:21.560
of year where you feel like yeah the weather's going to be clearing up but

00:04:19.199 --> 00:04:24.840
then no it starts snowing in Florida well with vessie and their dry sock

00:04:23.120 --> 00:04:28.960
guarantee it doesn't matter you'll be ready for any weather any time of year

00:04:27.199 --> 00:04:33.440
so maybe pick up a pair of their weekend chelseas they combined yearr round Style

00:04:31.479 --> 00:04:37.320
with a hight traction Rubber Sole and a cozy fleece lining that keeps your feet

00:04:35.199 --> 00:04:40.160
warm and dry all while still letting them breathe so you don't have to worry

00:04:38.600 --> 00:04:45.400
about knocking anybody out when you go to take them off go to v.com sshort

00:04:42.800 --> 00:04:48.479
circuit to get an automatic 15% off your first purchase we going to have that

00:04:47.000 --> 00:04:52.440
linked down below like I mentioned before the enclosure is one of the

00:04:50.479 --> 00:04:55.600
biggest changes here it's just like a lot of the other 3D printers in the

00:04:53.680 --> 00:04:59.800
market now uh their previous printers you would have to buy or build a

00:04:57.639 --> 00:05:04.160
separate enclosure that made them like way bigger but this one nice and Compact

00:05:02.400 --> 00:05:09.039
and includes an enclosure and part of that is this door which is actually

00:05:06.520 --> 00:05:12.199
pretty cool and it does open and lock in a few different places and you can

00:05:10.440 --> 00:05:16.280
actually flip the hinges to the other side which is pretty cool there is also

00:05:14.080 --> 00:05:21.240
a vent on the top here you can see and this vent is important when you're

00:05:17.479 --> 00:05:23.840
printing pla or PG because uh despite an

00:05:21.240 --> 00:05:27.840
enclosure being helpful for like keeping dust down and whatnot and and regulating

00:05:26.400 --> 00:05:32.479
the temperature so that if somebody opens an exterior door you don't get get

00:05:29.800 --> 00:05:36.880
a big rush of cold air PLA and petg don't really like it when it gets really

00:05:34.160 --> 00:05:39.720
hot uh so you're better off keeping this open to keep the temperature down but

00:05:38.639 --> 00:05:46.080
then you still get the benefits of an enclosure on the outside they've got these cool like cutout things uh which

00:05:43.680 --> 00:05:50.360
are perfect for this side like you can see with the included thing putting your

00:05:48.479 --> 00:05:53.919
spool of filament and then the filament feed you can see the tube is poking out

00:05:52.440 --> 00:05:58.720
right there so you put your spool on feed your filament in there and it doesn't take up any additional space on

00:05:56.639 --> 00:06:01.960
the back or the side of the printer it is INS set and and then you also have

00:06:00.199 --> 00:06:05.479
the same thing on the other side in the future once they have the multimaterial

00:06:03.199 --> 00:06:08.639
add-on kit available I guess you could probably put another spool here and that

00:06:07.199 --> 00:06:11.319
could be two filaments and maybe put three more on the top I don't know we'll

00:06:10.360 --> 00:06:18.880
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

00:06:15.599 --> 00:06:20.560
Ethernet Jack NFC which is used for

00:06:18.880 --> 00:06:23.919
pairing Wi-Fi more easily if you download the app you can then like NFC

00:06:22.599 --> 00:06:30.880
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

00:06:28.800 --> 00:06:35.440
Wi-Fi module is located it's inside of here and then there's a header here

00:06:33.120 --> 00:06:40.240
which at least on the mark 4S is used to connect an accelerometer uh I know that

00:06:37.479 --> 00:06:45.720
they also have a gpio hacker board thing where you can use the printer to send uh

00:06:43.400 --> 00:06:48.919
signals to other things what that is it's kind of up to you you could use it

00:06:46.960 --> 00:06:52.039
to like trigger a DSLR camera if you're doing a time lapse or something like

00:06:50.160 --> 00:06:56.919
that and then there's a USBC Port which I don't actually know what is for power

00:06:54.440 --> 00:07:01.080
button power plug which we're going to need now a lot of this printer is very

00:06:58.759 --> 00:07:07.120
similar to the previous prusa bed Slinger style printers like the mark 4S

00:07:03.280 --> 00:07:09.039
so you have your z-axis screws here um

00:07:07.120 --> 00:07:12.800
there's three now which is interesting this axis I think it's the xaxis my

00:07:10.960 --> 00:07:18.360
brain always screws this up uh it's a linear rail now instead of two rods I

00:07:16.160 --> 00:07:24.360
don't know why they've made this change but that's what it is now uh and then

00:07:21.240 --> 00:07:26.879
there is two sets of steppers for the Y

00:07:24.360 --> 00:07:31.919
AIS now instead of just one Lighthouse Beni 17 hours that might be a little too

00:07:30.160 --> 00:07:35.840
much sauce fast forward some amount of time the printer is actually out now so

00:07:33.560 --> 00:07:38.840
we've got public access to the profiles and we can go through this like you

00:07:37.080 --> 00:07:42.080
would at home if you were to buy one of these so I've got prusa slicer

00:07:40.440 --> 00:07:46.720
downloaded on this lovely MacBook here which is not mine thank you Jake Bell for letting me borrow it now it's worth

00:07:44.440 --> 00:07:50.960
noting you don't have to log in to use this printer at all you can use this

00:07:49.039 --> 00:07:54.879
printer with any slicer that's compatible with it you can use it

00:07:53.120 --> 00:07:57.919
without having to log in without having to connect to the internet you just take

00:07:56.360 --> 00:08:01.560
the USB stick out plug it into your laptop which I guess we're not doing

00:07:59.680 --> 00:08:05.319
because it's a Macbook and it only has type-c plug it back in and print but I'm

00:08:03.879 --> 00:08:09.080
going to use the account anyways because I think that this is how most people

00:08:06.919 --> 00:08:12.479
will do it and it does allow us to show off some of the cool online features

00:08:11.080 --> 00:08:18.800
that it does have there's lots of places you can find stuff to print thing of ours printables um maker world I usually

00:08:16.680 --> 00:08:22.599
like to use printables which is P's own service because it's just got nice

00:08:20.360 --> 00:08:26.159
interface good quality models there's lots of fun stuff on the main page which

00:08:24.520 --> 00:08:30.919
honestly is probably the main thing for me speaking of cool models on the front

00:08:27.879 --> 00:08:33.839
page I scrolled past this M1 Pro Car Kit

00:08:30.919 --> 00:08:37.120
card that looks pretty sick and I think it's complicated enough with some

00:08:35.800 --> 00:08:42.240
overhangs and stuff that this would be actually a good way to test this printer

00:08:39.159 --> 00:08:45.320
so we're going to do this now what color

00:08:42.240 --> 00:08:49.640
was there ever an orange Pro

00:08:45.320 --> 00:08:52.080
car oh yeah okay I like red Red's a good

00:08:49.640 --> 00:08:55.680
color they made a M1 in red did they not yeah they did hell yeah actually there

00:08:53.920 --> 00:09:00.000
was even a pro car that was red perfect see you later orange lipstick red pla

00:08:58.600 --> 00:09:05.760
you know if you've ever done 3D printing or looked into 3D printing you probably heard of pla pla is great uh because

00:09:04.240 --> 00:09:10.240
it's really easy to print with it doesn't like to like stick to the nozzle

00:09:07.720 --> 00:09:13.880
and gum it up it doesn't clog it doesn't really wear out the nozzles it's

00:09:12.320 --> 00:09:17.360
dimensionally pretty stable the only thing it isn't uh is good at high

00:09:16.040 --> 00:09:21.440
temperatures so if you're printing something for inside your car not going

00:09:19.680 --> 00:09:25.040
to work unless you live somewhere where it's literally cold all year round I was

00:09:23.600 --> 00:09:28.839
designing like a little phone mount for my car and printed like a test version

00:09:26.880 --> 00:09:33.399
just to check the dimensions and stuff I printed it in LA and like a day of it

00:09:31.720 --> 00:09:37.920
sitting out in like not that hot Vancouver weather it it was like drooped

00:09:36.240 --> 00:09:43.000
way down it didn't even have a phone on it we're going to pick print pla I'm

00:09:41.000 --> 00:09:47.120
going to change the infill uh the default grid is like fine when you're

00:09:44.880 --> 00:09:52.160
just printing something that you just for looks or whatever but I pretty much

00:09:48.959 --> 00:09:55.839
always use adaptive cubic which is

00:09:52.160 --> 00:09:57.880
pretty much the same speed as the grid

00:09:55.839 --> 00:10:03.120
pattern but it's three-dimensional so whatever you print is not exactly but

00:10:00.600 --> 00:10:07.760
more equally strong in all Dimensions than the grid pattern which is like

00:10:04.800 --> 00:10:10.480
across so vertically might not be as strong and the cool thing about the

00:10:08.839 --> 00:10:14.399
Adaptive One is if there's big voids in your print like in the middle you see it

00:10:12.279 --> 00:10:17.959
like it just leaves empty space there and puts the more structural stuff in

00:10:15.959 --> 00:10:21.160
the parts that actually matter it's very cool okay I played around with it a

00:10:19.519 --> 00:10:26.240
little bit more we're going to do 20% infill so a little bit less point two

00:10:23.600 --> 00:10:30.480
layer height by default and then I have adaptive layer height enabled and I just

00:10:28.160 --> 00:10:34.120
left it at the default told it adaptive and sliced it and it says 6 hours and 20

00:10:32.600 --> 00:10:37.399
minutes so that should give us a pretty good balance of you know the tops of the

00:10:36.079 --> 00:10:41.480
model being pretty smooth but it printing relatively quickly so prus

00:10:39.720 --> 00:10:46.200
connect is their online Cloud platform I guess this allows you

00:10:44.120 --> 00:10:48.639
to be like in a different place than your printer and as long as it's

00:10:47.240 --> 00:10:52.279
connected to the internet and ready to go you can queue up prints from anywhere

00:10:50.839 --> 00:10:56.360
so you can see the file transfer to prusa connect is already done and then

00:10:54.240 --> 00:11:00.880
it needs to download to the printer which you can see hey downloading now

00:10:58.639 --> 00:11:06.079
this is one of my pain points with this thing this is a 12 megab G-Code which is

00:11:03.320 --> 00:11:10.000
on the larger side G-Code being like the file that tells the printer what to

00:11:07.639 --> 00:11:13.720
print but as you can see the remaining time on this file transfer says almost

00:11:12.279 --> 00:11:16.920
10 minutes now I don't know if it's actually going to take that long and

00:11:15.399 --> 00:11:22.680
we're talking 12 megabytes I'm not not 12 gabes 12 megabytes the reason that

00:11:20.360 --> 00:11:28.800
this is so slow is because they're using this like really crappy Wi-Fi module

00:11:26.079 --> 00:11:31.600
that um it's pretty cheap and uh it actually does does the file transfer

00:11:30.160 --> 00:11:36.519
over serial which is a bit of a limitation now I complained about this

00:11:34.519 --> 00:11:41.480
to them because my home printer I have the same problem where the file

00:11:38.000 --> 00:11:43.360
transfers are just excruciatingly slow

00:11:41.480 --> 00:11:47.079
and apparently it has set a bit of a fire off at prusa so maybe by the time

00:11:45.800 --> 00:11:51.200
you're watching this video they'll have released a new version I don't know

00:11:49.040 --> 00:11:55.800
however if you use prusa connect they have this cool streaming feature where

00:11:52.519 --> 00:11:57.279
the G-Code streams from P connect to the

00:11:55.800 --> 00:12:01.800
printer so it can actually start before it's even done the transfer uh which

00:11:59.240 --> 00:12:05.760
which is very cool kind of resolves some of the concerns I just brought up but if

00:12:04.000 --> 00:12:08.399
you have an unreliable Wi-Fi connection and it cuts out partway I could

00:12:07.040 --> 00:12:13.440
definitely see how it would cause some problems for you on a printer of this

00:12:10.839 --> 00:12:16.160
Echelon I want 5 GHz Wi-Fi you're paying a lot of money it should be a little

00:12:14.639 --> 00:12:19.959
better than this since we're printing pla we've got to open the little top

00:12:17.800 --> 00:12:26.399
vents as per the instructions that allows cool air to come in 25 out of 20

00:12:24.160 --> 00:12:30.839
so its Target is 20° which means the fans at the back are going to be running

00:12:28.720 --> 00:12:34.880
constantly can I feel them to try to keep the chamber cooler oh I didn't

00:12:32.839 --> 00:12:38.720
realize there's like LEDs here but what I do know is there's LEDs behind here

00:12:37.320 --> 00:12:43.279
that's just to make it a little easier to see your print oh you know what it's

00:12:40.800 --> 00:12:48.160
also for to make it easier to see with the camera right I forgot about that hey

00:12:45.920 --> 00:12:52.040
you see look at that there's a camera it doesn't have like a time-lapse

00:12:50.320 --> 00:12:55.279
mode or anything like that as far as I'm aware which I feel like it probably

00:12:53.560 --> 00:12:59.959
should and the fact that it's a separate product in general is kind of weird at

00:12:57.480 --> 00:13:07.000
this price point 1,200 $ should come with better wi-fi and uh a

00:13:04.839 --> 00:13:11.160
camera by default it's not an expensive camera like how much does this thing

00:13:08.279 --> 00:13:14.480
cost prusa okay so the camera is $40 does feel like it should just be

00:13:12.440 --> 00:13:19.680
included now to be fair I I almost never use the camera on my mark 4S prusa

00:13:17.240 --> 00:13:22.839
because it is so reliable I actually don't know if I've ever had a print

00:13:21.199 --> 00:13:26.399
failure on it it's pretty high resolution it's like nice and sharp so

00:13:24.600 --> 00:13:30.000
that's good at least I guess at this point let's just let this print and

00:13:28.040 --> 00:13:33.079
we'll come back and see the results and let's take a look at our prints so I

00:13:31.519 --> 00:13:38.000
ended up printing a couple more things and a couple different materials to try

00:13:34.880 --> 00:13:40.440
things out um but this is the first

00:13:38.000 --> 00:13:45.720
print with our variable layer height in pla it's not the cleanest thing ever I

00:13:43.519 --> 00:13:50.079
don't know if the variable print height is the best thing ever and I think

00:13:48.360 --> 00:13:54.000
there's just some wonkiness in this model in the back you can kind of see

00:13:52.040 --> 00:13:58.120
you can kind of see there's some voids there on the overhangs but I mean it did

00:13:56.160 --> 00:14:02.000
warn us about those to be honest the overhangs on the Wheel Es are not

00:14:00.279 --> 00:14:06.240
perfect but they're pretty damn impressive for the amount of just like

00:14:04.360 --> 00:14:10.199
free hanging plastic that's there and how thin that is and how aggressive of

00:14:08.360 --> 00:14:13.680
an angle it is it looks pretty good but you can see hey the variable layer

00:14:11.800 --> 00:14:17.880
height sometimes is obvious on the side you can see the spots right there this

00:14:15.600 --> 00:14:21.880
is with the speed profile and and definitely not like tuned for maximum

00:14:20.440 --> 00:14:25.120
quality or anything like that and to be fair I didn't dry the filament at all

00:14:23.600 --> 00:14:29.720
ahead of time if you're new to 3D printing buy a filament dryer dry all

00:14:27.000 --> 00:14:33.199
your filament it will make things so much easier because that one wasn't

00:14:31.560 --> 00:14:36.680
perfect I decided to print it again in a different filament without variable

00:14:35.000 --> 00:14:39.759
layer height aside from just on the top to smooth that out a little bit and with

00:14:38.839 --> 00:14:45.320
a .15 height elsewhere and also with no

00:14:43.160 --> 00:14:50.000
supports and like overall in terms of like print quality it seems to be

00:14:48.000 --> 00:14:55.279
exactly as I would expect it's basically like a mark 4S and I guess I can

00:14:52.000 --> 00:14:57.759
assemble a car hey look at that you can

00:14:55.279 --> 00:15:02.560
see our first attempt at the wheels not bad second tempt looks a little bit

00:15:00.279 --> 00:15:06.240
cleaner I did have a chance to dry this marble filament before we used it so I

00:15:04.560 --> 00:15:09.920
think that that's definitely part of it and then it would be weird if we had red

00:15:07.560 --> 00:15:15.440
tires so we also printed tires but these are out of a soft filament you can see

00:15:11.920 --> 00:15:17.160
this got some squish I used duramic TPU

00:15:15.440 --> 00:15:20.639
I mean TPU assuming that it's dry is fairly easy to print with because it's

00:15:19.480 --> 00:15:24.399
so sticky it's not like it's going to peel

00:15:22.600 --> 00:15:27.240
off of the build plate I didn't test the tolerances on using different materials

00:15:26.160 --> 00:15:34.560
cuz some of them shrink a little differently than others stick it on there anyways nothing a little glue

00:15:30.600 --> 00:15:36.800
couldn't fix I mean it it rolls but like

00:15:34.560 --> 00:15:41.800
you might lose a tire now let's talk tricky filaments

00:15:40.240 --> 00:15:46.319
because let's be honest the big draw of having an enclosure is being able to

00:15:44.199 --> 00:15:50.160
print filaments that require like a heated environment because they're so

00:15:48.279 --> 00:15:55.920
high temp that if you don't have it they will warp and uh warp they did this is

00:15:53.120 --> 00:16:01.040
with print PC blend which is designed to be like an easier to print polycarbonate

00:15:58.720 --> 00:16:05.040
um this is a material that prints at a very high temperature is traditionally

00:16:03.279 --> 00:16:09.279
quite difficult to print with I left the filament in a heated dry box in between

00:16:07.839 --> 00:16:14.440
these two prints for several hours and you can see on the left the results are

00:16:12.279 --> 00:16:18.040
quite a bit better the second go around this is with the satin build plate and

00:16:15.959 --> 00:16:23.880
it looked like it adhered pretty well at the start but this was like a 5 six hour

00:16:21.560 --> 00:16:29.440
long print and eventually it did start to warp I tried to print them all in one

00:16:26.120 --> 00:16:31.839
go and these are very tall and the

00:16:29.440 --> 00:16:36.440
spaghetti happened so while having an enclosure is definitely nice uh for

00:16:34.279 --> 00:16:41.519
printing more complicated Advanced filaments like this it's not a magic or

00:16:39.440 --> 00:16:45.920
silver bullet but it does offer some other nice things uh I definitely

00:16:43.720 --> 00:16:49.920
noticed that this printer is way quieter than the mark 4S I'm not sure how much

00:16:47.759 --> 00:16:53.720
of that is because it's a core XY design and it's not like moving this giant bed

00:16:51.720 --> 00:16:56.720
back and forth versus how much is from the fact that it's an enclosure I

00:16:55.120 --> 00:16:59.759
imagine the enclosure is a big part of it because I was having problems with

00:16:58.120 --> 00:17:05.079
the other model I tried a different little like clampy guy it's a little bit

00:17:01.959 --> 00:17:06.880
smaller and this one printed pretty much

00:17:05.079 --> 00:17:11.839
perfectly I tried the textured build plate and if you look at it it doesn't

00:17:08.400 --> 00:17:14.799
look like it warped much at all maybe a

00:17:11.839 --> 00:17:19.760
tiny tiny little bit on the first print I had everything on there and uh the

00:17:17.520 --> 00:17:24.160
screw you can see there's a giant glob on there if you're doing Advanced

00:17:21.679 --> 00:17:30.120
filaments like this highly recommend trying the uh hardened obsidian nozzles

00:17:27.720 --> 00:17:34.760
that they sell uh you you can also get like fancier nozzles from other vendors

00:17:32.919 --> 00:17:38.880
that work with these printers because the stock brass nozzles that come on

00:17:36.600 --> 00:17:43.880
here are very sticky for certain Plastics especially polycarbonate and as

00:17:42.039 --> 00:17:49.520
it builds up you're just going to have situations like this overall thoughts

00:17:46.240 --> 00:17:51.880
then if you're willing to get DIY and um

00:17:49.520 --> 00:17:56.520
I don't know the exact amount of time it will take to build a machine like this

00:17:54.280 --> 00:18:02.880
because the DIY kits aren't out yet but when they are it's about $250 less

00:17:59.400 --> 00:18:04.120
you're looking at 950 USD to buy the DIY

00:18:02.880 --> 00:18:08.799
kit and if you want to compare to the mark 4S it's about $200 less uh

00:18:07.159 --> 00:18:13.200
regardless of if you're doing DIY or buying pre-assembled you're getting

00:18:10.400 --> 00:18:17.080
bigger build volume which is always nice you can print bigger stuff you're

00:18:14.960 --> 00:18:21.240
getting a quieter printer one that takes up less space assuming you were going to

00:18:18.760 --> 00:18:24.840
buy a mark 4S with an enclosure it's better than the marvs in a lot of ways

00:18:23.280 --> 00:18:29.159
it still has some of the same issues like the Wi-Fi is not great it's not the

00:18:27.280 --> 00:18:33.039
most beginner friendly like don't get me wrong I I can understand why people Buy

00:18:31.120 --> 00:18:37.799
printers from like bamboo Labs for instance um they are very newbie

00:18:35.799 --> 00:18:43.960
friendly you also have to consider the rest of the market price comparison wise

00:18:40.679 --> 00:18:47.440
your other options x1c from bamboo Labs

00:18:43.960 --> 00:18:48.760
the new creality is it K2 Pro I think is

00:18:47.440 --> 00:18:54.159
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

00:18:52.240 --> 00:18:59.400
system if you are looking for a multimaterial setup um which to be

00:18:57.000 --> 00:19:03.799
honest the prusas they have their mm mu3 which is a multimaterial setup it can

00:19:00.960 --> 00:19:10.320
only do five materials and is a lot more bulky than the uh the bamboo equivalent

00:19:07.039 --> 00:19:12.480
and creality has a similar setup uh but

00:19:10.320 --> 00:19:15.240
with way bigger build volume on the printer that's in the similar price

00:19:13.880 --> 00:19:19.320
class as this so there's a lot of competition but if you go with a prusa

00:19:17.880 --> 00:19:23.559
you're getting something that is repairable with parts that you can 3D

00:19:21.679 --> 00:19:26.960
print yourself to replace if you need with a big Community behind them and a

00:19:25.360 --> 00:19:31.000
lot of modding support even though this printer like came out a couple days ago

00:19:29.520 --> 00:19:35.159
there's already accessories that they made first party like I saw this cool

00:19:33.080 --> 00:19:39.039
door you can put on to make a dry box inside of here definitely recommend that

00:19:37.400 --> 00:19:42.520
um and who knows what the community will develop I think it's pretty sick if

00:19:40.720 --> 00:19:45.200
you're going to buy a mark 4S you should probably just buy this one instead if

00:19:43.960 --> 00:19:48.960
you care about spending your money on something you can actually fix and

00:19:47.240 --> 00:19:53.039
upgrade I didn't even mention that they're actually going to offer this as

00:19:50.400 --> 00:19:57.159
an upgrade kit for the mark 4S for like 400 or 500 bucks us we'll put it on

00:19:55.480 --> 00:20:03.720
screen however much it is it's not out yet but that's a pretty compelling upgrade if you want an enclosure I uh

00:20:01.360 --> 00:20:08.640
I'm very very tempted personally prusa you still got some work

00:20:06.240 --> 00:20:11.640
to do but I like this thing and I like you so get subscribed hit the like

00:20:10.200 --> 00:20:15.840
button and let me know what you think about this prusa core one
