a year ago we took a look at the prusa markv today we're looking at the prusa
Mark 4S which is a big upgrade and for
the same price or if you already have a markv only a $100 upgrade kit so we're
going to take a closer look at some of the upgrades that theyve put into it
we gummy bears as always we use the
crues around the office quite a bit they're one of the workhorses we have
around here and I'm looking forward to adding these
ones to our Arsenal and upgrading the ones we have to
this as always another USB stick
anything else hiding yes many things
hiding more boxes in this box we have
the accessory kit which has a bunch of tools a
filament guide spool holder and some
lube and a couple of other odds and ends
and a spool of filament Galaxy black
always pretty most of the parts of this are similar to The markv but there are
two big improvements one is the part
cooling shroud and fan system which is going to allow for faster Printing and
way better overhangs and something we can't see right now is a new hot end to
allow for way higher flow rates some of the other quality of life upgrades are
the screen cover which is now injection molded and some of the more mechanically
robust parts are printed out of a polycarbonate carbon fiber infused
filament the unit we got was fully assembled so just take it out of the box
put it down plug it in and go they say it would take you about 10 minutes to
get from out of box to your first print let's flick it on one of the other
things they've released is a mobile app and an update to their desktop app this
allows you to browse through your printers start and stop prints and you
can set up print notifications for either failures or successes and other
General printer status information setup pretty straightforward you just tap the
NFC with your app going and scan a QR code to get it set
up as with all PR printers you don't need to have it set up to the Wi-Fi and
you can print completely offline if you want to let's finish up the self tests
and calibrations it's going to go through and just make sure that all the systems are behaving the way it expects
to make sure that it arrived in fully functioning
order hi there o nice and quiet
one of the things I appreciate with the prusa systems is they go through the
self testing calibration right at the start and then after that you pretty
much never have to recalibrate them unlike some of the other systems which
run it before every single print which can take a lot of extra time when you're
running a lot of prints it's all the main axis
done and heat testing this might take a
minute that's probably a good time to cut cut cut cut since we didn't build
this printer ourselves we don't have to deal with the gearbox test but from what
I've seen it's pretty straightforward all right now we're
going to take out the filament and make sure the filament sensor is working correctly insert filament make
sure doing more calibrating and
remove sweet happy printing now that the
printer is all set up and ready to go let's give you a word from our sponsor

while this is heating up one of the other changes they made was to put some
more bearing style engineering materials on the inside of the gearbox housing
just to give smoother running in the long term generally speaking prusa
doesn't push printed as fast as you possibly can but one of the things they
did include on this is an 8-minute Beni which I'm very curious to see how that
runs that was really
fast and it looks really good especially
given how quickly it printed obviously not a regulation Beni it's a little
Hollow but still for how quickly that
printed this looks spectacular one of the big things that
they claiming is to be able to handle 75° overhangs without any support
cleanly I've done a couple of test prints on some of the other printers we
have in house we'll start a print here and see how it turns
out overall I'm really excited for the
upgrades that this brings and I'm probably going to reach out to them
today to get a bunch of kits to upgrade all of our printers internally cu the
speed Improvement and the quality improvement looks substantial and all of
these upgrades coming at the same price point as the original printer at $800
for the build your own kit and ,100 for the
pre-built it's pretty compelling if you want to see us talk about other printers
