I'm assuming this is working too loud sound good cool okay my name is todd blatt
I have a presentation about crowd-sourced 3d printing that I want to
show you I want to tell you a little bit about myself and what I do I run a
company called custom 3d stuff we are based in Baltimore so it was a easy trip
for me to get here I started it in 2011 I've been making 3d design since 97 I've
been doing 3d printing since 2004 and then I started my company in 2011
officially I make a lot of jewelry so a lot of these 3d printed earrings
and shapes that you couldn't make other ways outside of traditional outside of
3d printing I make a lot of Star Wars props movie prop replicas for collectors
and these aren't like just desktop FTM prints they're usually a high-end made
from at the actual metal or the real parts that they use when they made the
movie props so this is like the the ring that Rose Tico had in the last Jedi and
the you know all the way down to the disassembling the mechanical iris that
they used and casting the band in brass and chemical etching the the faceplate
so it really functions I do short runs of projects for
collectors so this is the ring from the Twin Peaks to TV show they commissioned
me to make rings for the new stuff for the new show so it was the actual
filming and then I made some of these for collectors this is a cast bronze
polished ring from Doctor Strange and I made a whole bunch of these Hodor
doorstop so a lot of like tongue-in-cheek jokes and then small
things and big things full Scott full size scale Han Solo in carbonite and
then silver rings in 2013 I started a a fun project it was just something that I
wanted to do people started getting these 3d printers and you know they they
figured I figured that they want to be a part of a fun project and work with
other people because in the past when you have you know blueprints or
something you're working on you're working by yourself and you can work on
in your own shop but now that we have you know the internet plus 3d printing
we're able to connect with other makers and say hey let's all work together on
one project so over the weekends Marty there who's on the Left built the
website we the builders com with the help of the rest of the team
Michael Raphael in the back right in the red shirt 3d scanned a sculpture and
I'll go through those steps here if you haven't heard yet it's called we the
builders calm you can download apart print it out and send it to us so if you
haven't signed up yet you can sign up for the next project and that's the URLs
we the builders calm so right now it's basically Marty and I aside from that
original weekend where we had you know this this team that's the sculptor of
there our third project is wearing the leather jacket on the right name Ryan
Kittleson so I'll show you his sculpture shortly so these are the first four
sculptures I have them here today from left to right we have the Georges
crowdsourcing ttan benjamin franklin stein rosie the riveter
and edgar allan print so these were all done by the community you know people
like you who have a 3d printer or access to one and then submitted the parts to
us after printing and mailed it to us you can see the original sculpture the
first one was it was sculpted in Italy about 185 years ago and then sent to
Baltimore it's of a young George Washington and it is 33 inches tall in
and it lives in the original Washington Monument in Baltimore so for a couple of
months while they were doing renovations we put it in the they put it in the
Walters Art Museum in Baltimore which is you know right down the street and we
were able to 3d scan it there and then use that for the project on the right is
a miniature of the hood on bust of George Washington of Ben Franklin and
that one's in the Metropolitan Museum of our 22 inches tall
we scan that like nine-inch sculpture and scaled it up to be the same size as
George then Ryan sculpted this one digitally Firpo and
this one we we separated it into two colors so for George and Ben it was you
know free for all and you can print any color you want just make sure the
outside surface stays the same for 4po it was our first time saying we want
either light or dark parts so we sorted those files separately so you could
choose to download a light one or a dark one and then print it in that color and
that that tone and then send it to us that way so we had the hair and the
jacket in the darker color and then there's a local artist in Baltimore
named Jen Schechter and she sculpted Rosie and clay about eight inches tall
and then again direct dimensions 3d scanned nylon with a the Faro arm a blue
laser and it picks up all the details and we scaled that up to the same 33
inch tall height as the first three and then chopping them into pieces
we used netfabb and meshmixer to do the slicing and each project was a little
bit different where we're cutting it for you know just cubes or rectangular
shapes and I was you know slicing so I didn't like have a line right between
the lips or or right through the eyeball trying to to move them so it made more
sense and then I deleted all of the solid cube blocks on the inside that way
no one had like a super boring print and there's no real need to have those
internal cubes the gorge project was a hundred and ten parts we did the whole
thing in three weeks including building the website doing the scanning printing
it assembling it and bringing up to the 3d printshow in New York which was I
think that the end of 2013 or 2014 Ben was a hundred and ninety eight parts
and he was sliced in netfabb we did the the George had all of the coordinates
engraved digitally so we have these XYZ coordinate systems so each block we get
we build one layer at a time and we can piece the parts together because even
even though you know that like X 4 y 3 Z 7 is right next to X 4 y4 z 7 it's hard
to tell which ways up and you have to rotate them and orient them properly and
there's like 24 different configurations in each block so it's it's complicated
even though you know the two parts are next to each other it turned out that it
was a whole lot of time to do this labeling for George a hundred and ten
parts and we had two people doing it and we were rotating the parts for best
arrangement for free nobility but once we scaled up to larger numbers of parts
it was too much work so we we just had people like labeling them with a marker
with a sharpie and they it's still really manual like I'm saving each block
from meshmixer or net fab as an STL and typing in its XYZ coordinates as the
filename one at a time manually but the the digitally carving each block was
just too much work so now you just once you print it out you you write it with a
sharpie and these are about half of the parts that users submitted for the Ben
Franklin project we made a little photo collage of them and people customized it
they write little jokes or notes or messages and send it in to us the first
one we received all the parts at my house the second one was at my
makerspace the third one was at a 3d scanning company the direct dimensions
one and then we had the fourth one also the fifth one which I'll get to in a
little bit was from was all sent to Santa Fe so we we did it a much larger
version of this and people are customizing it there's like a resin
print the Bronzeville the sharpie colors are swapping filament and the first four
sculptures we use e6000 to assemble it here's just some of the
pictures of the boxes being sent in and loaded up so we can move on I sorted
them into layers so this is Ben and it's sorted into the ten layers so we solved
the puzzle by putting them all in a ring or and arranging them based on like
where they go from its X x and y coordinates once you sort them by Z then
you have like all the all the first layer parts together and then you can
arrange them in a circle and and glue them together that way so here's at the
last Baltimore node our previous space is where I assembled this one so we did
each layer one at a time and then stacked up the layers and yeah I draw I
travelled him around so I have like George in the seat with a seat belt on
because that's kind of an easy way to bring him to different places and here's
the finished George Ben and Rosie and Poe this one actually is a photo from
the 2018 East Coast RepRap Festival I took it over there so the nation of
makers conference was in Santa Fe two weeks ago and we were contacted to build
a huge version and I thought these 33 inch tall like meter tall sculptures
were we're large you know each block takes hours to print and then there's
hundreds of them so I thought that was a big project but the conference said hey
we want a big one we're gonna have Adam Savage help and we want you to make at
least a six foot tall sculpture and it's in two months and I said that's crazy I
don't know if we can do it let's try and do it so I went and chopped up the same
model that we had I scaled it up I offset the outside surface inward six
inches so I have like a thick wall around the outside and then saving each
one of these parts was still one at a time because it's
you know I have to give it the XYZ coordinates we we didn't have an
automated process for it even though netfabb ultimate has this built-in it
doesn't like seal the mesh it only gives you the outside surface so I couldn't
use that because you can't print you know just the outside surface so but it
saves the files perfectly and it labels with XYZ coordinates and saves each STL
just it doesn't seal it so it wasn't useful so we put a call out adam savage
announced that on his blog lamar freed put it up on Adafruit and we had a lot
of people share it we had over 700 people help over the five or six weeks
that we were printing parts and we had them ship all the parts to the Santa Fe
makerspace make Santa Fe which is where they were hosting the nation of makers
conference at a conference center downtown so this had about four or five
hundred attendees from different maker spaces people who either organized a
maker space run a maker space own a maker space or want their makes her
space to improve so it was a really neat conference and just neat to meet all
these people there and now here's about six or seven hundred of the people who
printed parts and mailed them in so everyone on the website gets there like
Google logo from their gmail account sent over and then there's a little
number next to each picture of each person of how many parts they submitted
so make Santa Fe had a room they stored all these big boxes those are 4 foot by
4 foot by 1 foot boxes and they were all filled up with all these parts it just
it's so many parts each layer was like hundreds of parts so each layer of the
new sculpture was about the size of one of the ones that I brought here I made
these blueprints so each outline you could layout and it was 21 layers so we
had 21 different blueprints of each 3 foot by 5 foot sheet people went through
found the parts laid them out so these next pictures are all just of the
different blueprints and one neat trick that I did for this
project was I made sure that the components each were rectangular prisms
and not cubes they were like taller than they were longer and wider so that way
we knew automatically which way was up or down and then if you looked at the at
the paper it would tell you kind of which way was up or down most of the
time so that saved a lot of assembly a lot of a lot of work because of the size
and cost of glue and weight and number of parts we were applying it we used a
caulk gun and the Loctite there's like a block type power grab all part of a
tease of bought a few cases of these tubes the conference gave us about a 20
foot by 20 foot area and coated the floor with plastic and we went and laid
these all out and built it we started a little bit Friday night build it all day
Saturday and then six hours Sunday so all these parts all these layers we had
about 40 people helping over the weekend and it was just everything was working
we came across some problems but we were able to you know fix them as we went one
of them was interesting because any part that was a curved surface on the bottom
couldn't be assembled that way so it's not something I thought of before so we
had to flip it over upside down so like the bottom of her elbow we couldn't
build that way so we had to flip it upside down to glue it but that made our
blueprints kind of mirrored so we had to transpose them in one of the directions
we then started building we needed to be movable so we have it in a few different
sections so this is the bottom section and it was then mounted to a platform
we're putting on the caulk the glue spreading it around it was really neat
to work with Adam so he helps all all day sunday was gluing parts together
with us and they were documenting it so that should be up in about a week or two
up on untested he has a video that they're editing together so there's the
plinth there was like a 4 foot by 4 foot base or so
for this project all the colors were skin tones so we just did a call-out for
skin tone colors and I don't have too many of this part because I was in their
building and and stacking the layers but it ended up being over 6 foot tall I'm
estimating 450 pounds and it was it was just massive it's the the biggest thing
I've ever made so it's really neat so that's a normal print all the way on the
left like a six six inch tall miniature Rosie the Riveter the
full-color one you can see here which is the 33 inch wall and that's that I had
my booth behind me and then the finished one on the right which wit which was I
think like six foot one inch we then had the fellows from make Santa Fe move it
to the New Mexico Museum of History so it's set up there for the for the next
six months at least maybe a little longer depending on how it goes and then
there's there's me and Jen with the with the final sculpture yeah please help so
if you guys have a printer or access to a printer then you can sign up we the
builders comm if you don't please meet someone this weekend who has because I
feel like everyone has access to a 3d printer we've been doing one build a
year after this conference after this build where it was like so many people
helping we have had several groups reach out to us asking for us to do do this
kind of thing at their event so it's you know something that we're interested in
doing as long as we can get it also work out and you know we'd love your help we
we literally can't do the project without people like you so it would be
really neat to have you tell your friends and help out with future
projects and there's the contact information for me and we the builders
at the bottom there and I have I guess time for questions we have 10 minutes or
so if you guys have any yep thanks
who here helped on the project anybody we have some here that's really neat
yeah we had like over 750 people because there was teams and people building and
then all the parts
I have personal cards for for my business I don't have we the builder's
cards but just sign up go read the builders calm and there's like a sign-up
button we have a Facebook group also it's like at we the builders yeah thanks
the question was is the file available for the smaller version we do have them
but they're not easy to act yeah in one piece for the small version the little
pink one in the corner there we do have the files for all four sculptures so far
they're not like easily accessible on the website but it's something that I
need to put up you can get to it if you go to like the file preview on the
website but it's not like a hot link URL or anything like that
you have to like right click view source and grab them yes we we have heard that
feedback we just haven't uploaded them that way yet yeah if you email me and
ask for it then I'll be able to post it there they're there but you have to hit
the f12 view source and and go through and grab the Amazon link so it's not
like the websites not so we the builders is a totally nonprofit like not
registered nonprofit just like a a project that we do so there's it's just
me and Marty making the website and building the building the parts and
getting people to sculpt in print and with that without like funding so it's
it's a lot of work to do but right now it's up on the website as the preview
URL for the in browser SDL viewer yeah
yeah sure
well I'm estimating it's 10,000 hours of printing for the big Rosie because it's
2600 parts in approximately 4 hours per per part so it's around 10,000 or 11,000
and then around the same four dollars of shipping costs to get them to New Mexico
and then I guess my time was about 80 hours of prep and getting all the files
ready and then the building time so yeah a lot of hours went into it I don't have
a specific count of number of countries but I know we had parts from every
continent except for Austria for Antarctica and then a lot of parts from
Europe and we had Singapore and China and South America there's a few
different countries that submitted par Saudi Arabia Italy yeah a lot of places
for four the question was that the shapes not solid so how did we do it how
do we know how much the material I take out the first one for George there's no
inside George was sculpted from marble at that scale so the back of George has
kind of hollowed out as a as a post so there really is no no depth to George
beyond what you see because it was carved from marble and was thick and
they needed to make it lighter for Ben since we scaled it up we introduced this
extra internal area so I just deleted every block that was a solid block so
there's no there's no solid parts inside Ben it's just the blocks that were on
the surface so they're about three or so inches thick all the way around for
Rosie at the small scale there's some hollow parts but it was just again
wherever there was a solid block I deleted it once I scaled it up for the
big Rosie I you know made a judgment call and I said well I think if if this
sculpture is six inches thick on average so I'll offset the whole part in like so
I have two or three blocks going deep in any direction so it's it's got that six
inch offset and then we built an armature inside I'm not sure if I had a
picture up here of the armature but if you look at her her left arm there which
is in the bottom of the frame you can see a white rectangle and that's where a
2x4 was slid in so it was kind of built around dowel rot two inch dowel rods in
2x4 so we could build a internal armature
yeah Adam Savage is a cool guy you can see like the hole for the dowel rod and
the arm and the front bottom left of this photo so that that hole there is I
think two and a half inches because we had a two inch dowel rod in there with
some space so it's it's really massive this is some of the support to buy for
our beams inside there and the posts going up
but occasionally we had a part that we would reject because either the color
was was very wrong or the print was poor or but for the most part all the parts I
got sent in and got used we send out emails because you're supposed to print
the part and then send it to us and if we don't receive it or don't hear from
you or never got like hey that part shipped we need it then we will send you
some emails and if we don't hear back then we release the part back to the
pool and some other people can print it but a lot of those we end up receiving
the part anyway so we have duplicates so then we kind of just whichever one we we
grab first of the two is the one that gets included but I think it was about I
don't know less than 5% great I will be at the table until the end of
the day and then a little bit yesterday so if you have more questions you can
reach out to me then
you
