Filament Friday is brought you every week by the generous donations of my patreon
supporters this is the wanhao duplicator 7 I got this from the ultimate 3d
printing store ultimate 3d printing store dot com
I brought in the expert Jim Carter you're big on social media what's your twitter tag.
Im on Twitter at JWC Productions I also have a small youtube channel another 3d
printing channel but I said Jim you want to help me sort this out because I can't
figure out how to get this thing to work and he was gracious enough to take it
home and he figured it out and now you've got several printers this is your
delta back this is my seemecnc rostock Max v3 and then you've got a wanhao
no mono price maker select version 2 which is like a wanhao Di3
so you're familiar with wanhao and then you've got a CTC yep CTC so
you're very familiar with FDM have you ever done SLA or the DLP what is this
SLA or DLP This is DLP. SLA uses a laser DLP uses some sort of a
projection onto something with UV lights to make it all cure so no lasers
I call this DLP my biggest thing is it runs Windows software or the software
for this is Windows I'm a Mac guy and I have a Windows laptop but I could not
get the HDMI port to work this requires an HDMI setup because it's like a second
screen on your computer you figured this out with raspberry raspberry Pi on the
SD card in the back you load your operating system which in this case for
this machine is something called nano DLP now this is software that's you've
loaded on the SD card that you put on the Raspberry Pi that's just running
Linux absolutely Linux in the background but
instead of Windows it runs a program called nano DLP so okay so
nano DLP is a program for this machine what's our only 30 bucks yeah make it
work another 30 bucks it's almost like why don't they put this inside right
now resin is the filament for these guys it's a liquid resin that you actually
pour into this thing and that's how you do your prints we've got some from mono
cure and then some came with the d7 some resin so you have some to print out
of the box and this Monocure actually donated some to the channel for you to
try out so we'll talk about these two guys how did the Wanhao stuff work
it was awesome I got three or four or five prints off of it even you're chess
pawn printed my chess pawn and I gotta tell you I'm a little surprised the ball
on the top it didn't get underneath the ball it kind of printed it straight but
the rest of is really really smooth this would be great for finishing but I
actually like the the results off my Prusa MK 2s and my CR 10 actually a
little better if I do a real fine print so I'm a little surprised by that but
you've got some other great prints here such as this Eiffel Tower and this was
actually done with the Monocure done with the monocure rapid grey so this
you were telling me which kind of bugs me this stuff stinks right so if you're
gonna use this type of printer that's one drawback because you've got to put
up with the smell yeah I don't necessarily feel that it's makes you
nauseous but there is definitely a smell enough so you definitely want good
ventilation and probably more than you would with a ABS printing which you know
I don't mind so the detailing this is absolutely incredible I'm blown away by
you can see the girders so clearly I'll show a close-up of this this was done
with the with the monocure so how would you compare would you say the monocure is
recommended that I mean personally between the two it seems like it just it
works nicer in the machine and it's something that's widely loved and
accepted by everybody in the community of this printer like Facebook with the
d7 group it's a lot of people or everything yeah everything I've read and
talked to people that's their go-to and what's the cost you know what the cost
is for a bottle of this I'll tell you you can pick up three bottles that you can pick
up the three bottle sample pack for I think it's under $100 u.s. we're right
around $100 so they're $100 comes straight out of Australia
and you've printed a bunch of stuff this thing's probably about half full yeah
more than half but you know this is the clear that's okay and you printed
actually printed a benchy what's interesting about this I wouldn't call
this a fantastic print which is typically what you are supposed to get
off this you printed you didn't print it flat is my point some things like this
that are larger you know the folks say to print on a 45 degree angle build the
supports and then send the STL over so yeah then you think I don't we mentioned
that you do send the STL to the Raspberry Pi and then it slices it and I
dropped the print. there's a lot of finicky things to learn with this and processes
where with FDM take a file slice it throw it into whatever your favorite
slicer is put it on a card and hit print this there's a lot of little
steps to be able to get to that okay all the additions he's made to it I want
you to explain some of these additions you got something here on top you got
something on the side you had a bunch of little pieces that you printed and these
are all printed on FDM, FDM so you kind of needed a printer to print for your
printer in this case yeah didn't have much of a choice something like this at
the top this printer is known to have a Z wobble issue pretty severely grab a
608 bearing from all those fidget spinners that we've thrown away and
there you go and that wobble is gone that is not moving at all okay so this
was just 3d printed that's it on your FDM put a bearing inside fix that issue you
got it okay and then you have some over here on the side that you've added what
does that do? so when this this is done there's there's a lot of ooze happening
from the from the loose resin so basically what you do is you take your
plate off bring it right over here and then your part would be sitting on it
like this now everything in the Z would be higher but now everything is gonna
drip right back down into the vat so you don't waste any resin okay then
you've got a few other things here you got like a cover yeah absolutely so some
of the other add-ons this just goes in here. we were done printing
and you you want to kind of cut down I use this to cut down on the smell myself
but also so nothing falls in here it gets dirty or dusty just like that so it
keeps the the resin you have in there okay so deep so this makes it easier
this makes it easier to drip the thing off but this you found actually needed
to get better prints out of it but all these are available on Thingiverse
just search d7 on Thingiverse wanhao D7 now the funny thing is this piece here it's
now stock on the new version 1.4 also they've actually added this.
What are the steps to post process remove from the plate with the gloves
remind you you have you have to wear gloves with this stuff you won't you
don't want this to touching your skin at all once it's removed you
have to take your prints carefully and put it in some isopropyl alcohol IPA and
let it sit for a little while and that will wash off the loose resin
that's still on the print once that's done you now have to finish
curing the resin. Is that where people put it outside in the Sun you can do
that that's one of the more popular ways I have a nail dryer that you find in a nail salon found it on Amazon.
You could do your nails while you are doing that. You can you just take the the print and the best thing to
do so the print has a nice finish and it's not sticky is to put your print in
a jar of water and then put that in front of the UV light to cure for an X
amount of time which I haven't figured out yet the benchy is yellow and
the rook is more of a frosted clear and that's because I over cured the Benchy
the castle here you got this it's a little castle this thing is really
detailed it's incredible and this is actually pretty clear absolutely so this
one came out good so if you get the post-processing right you can get down
to some really clear cuz you could never 3d print this with FDM. Not that
level of detail not that small. Not anything I've seen anyway so
there's so there's a lot of steps to this if you weren't familiar with all
this hopefully this has helped you guys out I know I learned a lot I'm glad I
gave it to him to deal with and so basically what you've told me is it
smells you got to do a lot of post-processing and you got to add a
Raspberry Pi to get this thing to work or at least it helps I don't know you
guys be the judge if this is the type of thing you want I could see where in
certain situations where you need that detail where you're making jewelry I
guess like things like that you've done some amazing prints just that shirts for
me but you know what you just keep this thing and if I need a print tell you
what. I'll get a hold of you. How's that for a deal. Absolutely.
All right thanks Jim, Thanks for going through this if you guys have any
questions you can get Jim on social media if you have questions or leave it
in the comments below we'll try to get them answered I hope this was helpful
not a typical review like I've done but thanks for stopping by.
Anytime thanks for having me. All right we'll see you next time on Filament Friday
